[ FEITENG H9500 ] Known issues and fixes

Ok.. i see many people on this forum asking questions about this device.. the truth is this device is designed very poorly and it even may arive at your hands defective / with some or with a lots of problems.. you can proceed by your very own responsibility. Take a look in the picture for pcb details
- to Fix about every problem you need to findout how to unscrew the back plastic case and be able to see its PCB (Printent circuit Board) - Its pretty easy, just remove the little screws and give a presure at the clips of the cover to be removed, don't use metal objects because you will scratch the plastic.
* WIFI / GPS very low signal
Let me begin with one problem that you have FOR SURE.. is the low wifi signal and gps.. this is due to a horible design of the antenna.. the antenna is not just horrible, but it is also causing a short circuit it self! which is the main reason why the signal is low. First you have to stop the short circuit from happning
How to fix it? Unscrew the back cover, at the top of the back cover under the flash you will see a white sticker, this is the antenna, you have to remove completely this white sticker because it can't be useful by any way. Remove every piece of it including the copper-yellow color from the inside (the place that makes the connection.
Now find a UTP cable and take a piece of a hard copper of it, remove the plastic and keep the copper wire clear, cut it and place it in the whole were previewsly was the white sticker.. you have to place it in this way so it can connect with the inside conntact with the back plastic is placed and screwed again on the phone.. there are 2 pins in that place.. the old antenna used both of this pins (that was causing short circuit) you have to use the left pin and leave the right pin completely empty.. so the right pin doesn't connect anywere, and the left pin is connected to your piece of copper wire.
Cut the copper at the same size of the top of your phone.. so you can place it horizontal ... but you can also try vertical, (use wifi analyze app from play store to see what fits better for you)
Now.. this is the same antenna for gps.. you have nothing else to do.. just install GPS Test app and go outside and test your gps..
This is what i did and im pretty happy with it, instead i used 2 pices of copper and i covered the whole top place of my phone under the camera.. but that doesn't mean is the most right way because when we dealing with antennas there are a lot of math / and calculations that have to be done to design a perfect antenna.
the wire gives really a great signal.. just in case you want to reach the extreme.. Instead of copper wire you can use thin-Copper paper. (don't use foil of aluminium is not good) and design a better antenna copying the design of an antenna from another phone (that you know it works)
* Camera autofocus doesn't work - Or camera doesn't work at all
[Don't unscrew] Frist thing you should try is remove the back cover and give a presure in the right side of your camera with your finger.. this is the place the connector is located.. and it may gets unclipped and loose the connection after a small drop or something. After that Reboot the phone.
[unscrew back] If this presure on the right doesn't fix it, then you have to unscrew the phone.. take off the camera and give it some small hits and punches.. place back the camera and see if it works.. this is due the autofocus motor got stuck.
* Mic, Speaker, USB doesn't work
[Don't unscrew] This is due the connector of the bottom part got lost its connection. remove the back cover and give presure under the place of the SIM cards, were it writes 'WCDM' and 'GSP'. press a bit those spots. reboot, if not fixed:
[unscrew back] The two bottom connectors is 1. for the touchscreen and 2 for the bottom parts.. you need to check both of those because i am not sure which is which.
* SIM1, SIM2, Microsd not working
[Don't unscrew] Try to give some press next to vol+ / vol- buttons
[unscrew back] On the top left of the PCB there are located 2 connectors, 1 is for the front camera, and 2 is for the SIM/SD parts.. the last connector to the side of vol buttons is the connector you have to check and press to make sure is connected ok.
* Touchscreen doesn't work
[Don't unscrew] Give presure right under the headphones jack
[unscrew back] This is were it is located.

Charging Problem
I would like to add the problem with charging the batteries.
I got a new H9500, with two batteries. When i try to charge it with the adapter that came with it, the phone shows the charging animation, but it never actually charges the phone.
I have the same behaviour on both batteries.
After searching for a solution i found these:
-The charger supplied is 5V, 0.5A. Some people used a 1A charger and got to the point that it actually started to charge
-ROM problem, by changing the ROM some people were able to fix the problem, since the software was not getting correct info out of the battery's third pin.
Well none of the above worked for me. I hope someone comes up with an altarnate solution.

I need a new usb pcb for my feiteng H9500 (the usb port is broken on it)
This is the part I need :
the ones on aliexpress and dhgate don't ship to tunisia :/

my expirience
Hello guys...
My story. Bought this phone for my son for 160 €. We found out that camera focus didn't work, so I took it apart.
The easiest way to take down plastic cover, after it was unscrewed, is to put something plastic under it in the place between both SIM cards places, and work around inner battery square.
When cover was off, I found out that camera plug (right of camera) wasn't even plugged in. It only laid on connector. Plugged it in, and shake camera a little and auto focus came alive.
After that I noticed that black cable between gsm antenna and PCB was very loose, so I had to sort this out
At the end I found out that speaker connections are very delicate and had to take plastic down again to properly connect speaker.
Now it is obvious to me, why these Chinese phones are so cheap. We have saying in our country: pay little, get little
But now everything is cool and my son is happy.... And I am happy

Hi.
I just got a Feiteng H9500. The problem is that the camera is not working and the camera application hangs then stop responding then quit. When I start the camera nothing apears on display. I've put some pressure then some hits and it started to work a while. The focus worked as well but It seems to me not to work excellent so I gave it more hits, then the camera stopped working again. I have disassembly it, i moved a bit the camera and removed and put back the connector and it came alive again for a while, but just the front camera. Then stopped again. I have noticed that the camera doesn't move up and down when I press on it, it is stopped down, if I lift it with a needle it goes up, so it's not stucked.I can't even comute between cameras because the aplication hangs then quit. ( Everything else works.
any help? Thanks.

Hi Guys,
Just ordered the HTM H9500, is it exactly the same Phone as the Feiteng H9500?
I mean can I use ROMs for the Feiteng H9500 to flash them on the HTM H9500?
Big Thanx

My phone is Feiteng H9500 (HTM).
Appearance is similar FEITENG h9500, but not identical.
I'm not sure that have the same Rom, so I did not dare to flash a custom ROM.
View here:
http://www.movilesdualsim.com/forums/feiteng-h9500.166/

I cannot read Spanish or whatever it may be
There is a ROM at needrom called something like this "feiteng / htm h9500".
That sounds like the device is the same...

Thanks to your photo guide, I found courage and disassembled my HTM H9500 and DG300 phones and fixed them easily (nothing to fix really, just blow off some dusts between camera connectors and in front speaker)

You should order it by the store you got the picture of it. actually there are many stores selling parts for this phone.. almost like its branded.. unlike with other chinese phones you get a struggle to find parts, so you shouldn't face any problem to order a part.

Sound when touch on Lock Screen
hi, guys
I have FEITENG (HTM) H9500 almost a year and I am very pleased with it.
I want to change the sound of the screen when touch lockscreen, but I do not know how.
It did not sound when unlock the screen, it is the sound when you put your finger on the screen while the screen is locked.
In The system/media/ui is not, and I do not know where I'd be looking elsewhere.
Please help

No Data connection
I have had a Feiteng H9500+ for a while but recently rooted it and tried some different ROMs as well as applying a GPS fix. Somehow now my AT&T data connection is not working. The SIM settings have the data on and set to AT&T and I turned roaming on just to be sure but nothing I do can get the AT&T data to work. When I am connected to Wi-Fi it works fine. This is the only way I can get Internet.
Can anyone help me get my mobile data working again?

[Q]Light Leak & Speaker[Q]

Purchased another Nexus 5 the other day, a black version, but when I got it I had to update to 4.2.2 from the box so I think it might have been a batch one device, also the speaker grills are the small ones.
At the top and bottom of the screen, a white bar is visible where the backlight is leaking. It doesn't affect the screen quality at all, and the light doesn't leak any further than the borders of the screen, but it's somewhat annoying at night. Also, it might sound silly but I do use the loudspeaker for gaming and for music sometimes. The one on mine is dreadful, just sounds tinny. Comparing it to my mothers and sisters, it sounds pretty much the same.. but with the larger holes on the newer model is it louder or any better in terms of quality?
Do the new batches have the light leak issue, I'm sure I've seen it mentioned elsewhere.

It seems the 310 batch isn't the only one suffering from issues. Even newer batches have similar issues including button rattles, simtray, light bleeds,etc. It has nothing to do with any new revisions since there is non, its been on rev11 since the release.. Its just your luck.

Life on a sidenote, when your USB Cable is inserted does it feels loose? By this I mean does it freely move from left to right, or is it quite firm in the device? Although it's still hard to pull out, I find my cable feels quite loose at the connection point.

Yes. The "teeth" will hold the cable in.

Yea it is lose. It holds on well but swings loose sideways. I tried using a Samsung charger and that manage to fit snuggly. I think its the micro USB of the charger that wears out after a while and not the port.

I think it's just a cheap cable, if you feel the cable compared to other OEM's it feels like cheap rubber though this has it's benefits! Might secretly swap my Dads Note 2 charger for it might seem trivial but it's one of those things that annoys me.

Lol. That's the first thing I thought when I first took it out the box. I also thought they mistakenly placed a different charger, figured it ought to have a Nexus logo on it too. But yea I guess thats part of the " cutting corners" to bring down the price. You can swap your dads charger but hell have to probably spend double the charging time considering the LG charger delivers less Amps compared to the Note 2's.

Things like that I think are just attention to detail and really mean a lot to me - but then again I'm purchasing an amazing device for £289. Would have preferred it if they started the prices at £329 and cut a few less corners. Can't be avoided at this price though, I guess.
Already switched the cables out. I was already using a Samsung wall connecter, he was using an old HTC charger, so his charge time shouldn't change. It's still a little loose but is much firmer again the phone, much better :victory:

[Q] My Z3 is bad. Was it bad luck and should I try again?

Hi,
I have a Xperia Z3 for a few months now. Software wise it's great, I really love it. But I have a series of very annoying hardware issues.
1) USB cable doesn't connect properly. Well, it does, but any movement breaks the connection. Touching the cable, even lightly, disconnects the USB. I lost a lot of time transferring files and accidentally pushing the cable, and it's super scary to install sensitive stuff via USB.
2) It gets really hot really fast. Playing simple games or browsing the internet for 5 minutes already makes it warm. Playing hardware intensive games for 20 minutes make the phone so hot that it's *really* uncomfortable to hold it. I can't play games outside because I can't stand holding the phone, and putting it in my pocket just makes my leg hot because the heat is spreading through my pants. Despite that, I never got a overheat warning. It happens with both stock and custom ROMs, so I don't think it's a software issue.
3) I got a small crack on my screen. I have absolutely no idea how it happened, but I don't think I was careless. Is the screen too fragile? I don't think so, this one is probably my fault , but might as well ask.
I'm asking all of this because these problems are really annoying me, and I want a new phone. I really love this software/spec-wise, so I'm thinking to get the same. But damn, if I buy another Z3 just to have the same issues I'll feel like the biggest idiot on the planet.
So, was it just a bad luck thing or should I go for another phone?
Thanks for reading.

Hi Hexenir
I've had my z3 for around 6 months now and think it's a great phone.
No. 1, have you maybe worn the USB port out by connecting lots and lots of times? (you mentioned you've used custom roms so I assume you've flashed more than the average user) Do you charge through that port too, thus increasing how many times you've used that port? I use a Magnector to charge so I only use the USB port to side load apps and mine is totally stable. I can move the phone around whilst it's connected and it doesn't break connection. Also, are you using the cable that came with the phone? Sometimes other brands can be sloppy fitting.
No 2, I can't really comment here because I don't play intensive games on mine. I have browsed reddit for easily a full hour and there might be a slight temperature increase but nothing I wouldn't expect. It's also sat in a case so I'd imagine it's harder for my phone to get rid of heat.
No 3, As I just said, I use a case so I've not got any cracks on mine (yet, touch wood) but I haven't ever dropped it either. I use a Roxfit case and I'm really happy with it. I always used to keep my other phones naked (no case) but the glass front and back made me feel paranoid about dropping it. There's also the issue that the z3 can slide if it's on a flat/smooth surface (mine slid on my bed duvet and I've heard they've slid across tables) so again, my case stops this.
These aren't cheap phones so at the end of the day it's your decision but if you do, I'd recommend a magnector and a case. Another thing I should mention, I switched to a magnector because I worried about wearing the water tight seal by opening it to charge every 3 or 4 days. Have you recently done a pressure test to see if you've worn that seal out?

The Z3 is a great phone, but ...
1)
USB - I usually use the magnetic port for charging and do most file transfers by wifi so the only usage of the USB port is for me flashing roms. Nothing happened yet but I guess this is something which can be fixed under warranty.
2)
My kids play Asphalt 8 on it and it does get warm but not hot. Before investigating further I would recommend doing a factory reset to see whether this resolves the issue. If not, warranty may help either.
3)
A pain in the ass and you are not the only one. Depending on your country you may have difficulties to get that repaired.

1- Bad USB? Have you tried using another cable and/or another computer to see whether the same problem persist? I highly doubt its software issue, wouldn’t harm to do a repair with Sony PC Companion. If you have tried all those mentioned above, I would assume it’s a defected phone, hardware issue.
2- I think its normal for the Z series, they do tend to get warm easily. I have the Z and now the Z3, both experienced the same thing. One thing is that heat disperse poorly on glass in compared to metal. This might be one reason why many OEMs do not use glass back anymore. I know its a shame, beauty or performance, your choice. However, i would say the Z3 disperse heat far better than the Z.
in addition to that, it also depends your location. Here in Vancouver, its mostly raining and windy, so heat isnt that bad in compared to Asia, Hong Kong/China etc.
Idle average CPU temp is 24 Celsius
Browsing average CPU temp is 30 Celsius - 40 Celsius
Playing games reaches 4x Celsius fast. I normally let it cool after reaching that high. Thus, i barely play games on the phone.
3- I do not believe that the Z3 has gorilla glass 3/4 so I wouldn’t bet on the glass is "tough." That said, I would advise you to put on a screen protector regardless of whether you like it or not. Trust me, a simple screen protector will hold the glass together. I had the Z before and dropped like x times and the screen didn’t crack at all. Dropped my Z3 few times and its still fine.

Well if I purchase a phone where the screen cracked randomly and have the issues u mentioned I would not buy it again.
With the screen crack Sony will refuse to repair it under warranty but u can still try.
I always have an insurance when I buy Smartphones. I paid 150€ and it covers everthing Sony will refuse to repair.

Just had to share this experience....

Well I have been a owner of a LG Nexus 5 for the past (almost) 2 years now, in fact I am coming to the end of my contract very soon and will be able to either goto another company or get a new phone.
Anyways, sometime ago I experienced a problem with my microphone and external speakers not working, or at at least some of the time... After a bit of research online I found out my problem was related to a connection inside the phone that connected the bottom assembly to the main board at the top of the phone. It required me to remove the back panel and a few screws to remove the plastic cover, but the poster suggested putting some tape on top of that connection to hold it down more firmly to the socket it connected too. So I did this. I put some black tap (electrical tape cut to fit.) on top and then assembled the phone again. Viola, It worked!
Well, a short time after I decided that I wanted to update my phone from stock kitkat (4.4.4). Always been curious about custom ROMs and gave Cyanogenmod a try. Not only that I got bold and tried the nightly releases of the new marshmellow update. After some time I started experiencing things not working, like the camera, and a lot of freezing, hang ups and random reboots (not so much the reboots as the constant freezing). Often I couldn't get anything on the screen or the phone to respond from a locked state and when I did, often the phone would lag so much, that doing anything would take a long time and proved to be impossible.
I started thinking it was the nightly releases as the source of my problem and just kind of shrugged it off and figured "they will eventually fix the problem". I kept this thinking for quite some time. But it occurred too me one day that something else was causing the issue I was facing for the simple fact that the lag started showing up in the recovery mode (also custom) and a lot of times would continue to show up after I rebooted my phone. Hence, would rule out any 'software' issues I was facing.
I began to think that my problem was hardware. Maybe it was just time for a new phone. But still months away from the end of my contract, this meant I would have to pay off the 'problematic' phone first before getting a new one. I really didn't like that idea. So while looking into this problem, in a last ditch effort, I opened my phone again. Dunno why but I also decided to get rid of the tap on the connection I tried to fix before... I popped off the connection there and had a look at it. It didn't seem damaged in any way nor did the socket. Strange as it was I put that connect back in the socket and put the cover plate back on making sure not to torque the screws and assembled everything back up....
Now the mic and ext speakers work just fine and the phone is working like I just opened the box and took it out for the first time. And I have not once seen any problems... I understand what's happening here... still just wanted to share that for it was definitely weird or what?

https://drive.google.com/open?id=0B0pUNVcVRCJ7MThMc0NHLUNkSEU
Sorry about the link, only way I can upload an image.
Just so there is no confusion... an image of the effected area, inside the phone. The arrow points to the connector and more importantly the area of the connector that seems damaged. If I press lightly where the arrow is pointing on this image, the assemable at the bottom (speaker/mic) will work, indicating a loose connection. Although after visual inspection, I cannot see any damage to connector or the socket. I suppose the only way to really "fix" the issue is to order a new part. As stated previously, already tried tape on the socket to help hold it down, but that seem to cause just as many issues with the phone performance. Any other suggestions?

When ordering a replacement part, you need to be careful because there was another XDA member replaced the same part with a cheap 3rd party solution and the phone would not charge until he replaced it with an oem part.

Does anyone else have issues with there ext. speaker and mic not working?
An update on the phone;
back to square one. My ext speaker and mic will not work. And that socket has something to do with the LCD connection on the screen as it will black out if just the right area on the back of the phone is pressed. Only way to revive the phone is to long-press the power button for a reboot. Then will come up fine but speaker and mic still do not work.

Wow, that sounds pretty low level tactics of LG... just shameful really, but not hard to believe these days...
Quite honestly, I am just going to replace the phone. Think I got a pretty good run out of it and think its pretty well time for an upgrade. Anyway, for the reason I got the phone, it wont matter the speaker and mic don't work. Just going to use it for development and it will be a good test device.

Oh an this post is related to this thread so I thought I would link it for it may help someone else facing similar problems....

I'm not sure that LG had anything to do with the low-quality replacement parts.
If I were you, look for a n5 with a smashed screen that is suitable for parts.

Good idea, except the iphone is the most popular phone around here ... find it pretty hard to find one, been looking. But thanks.

I have seen quite a few busted n5 phones in Toronto. I have managed to get working phones with a smashed screen for as little as $30 which is rare for Toronto. Average I pay is $40 to $50. For this price, I either use the phone for parts in several phones or I get third part screen from Aliexpress for around $40 CAD.

I just want to update this as well...
I am fairly certain (now thinking about causes) its not really a design flaw, but more so because I frequently sat on my phone when it was in my back pocket...

It was not me but I had that same experience. Replaced with a cheap oem and it didn't charge after that.
I found out why. The charger usb socket was not connected to anything ! Unbelievable! It lacked the black plastic backing for that part of the cable to connect to.

Which component did I destroy? (Almost all lte/hspa+/edge packets are lost.)

Hi,
I replaced the screen of my brother's Nexus 5 and even so the display works perfectly we seem to have destroyed a component.
I managed to connect the device to lte/3g/2g networks (see photo in the attachment) and sometimes a few packets are even successfully transmitted but that's an exception. Usually it is not even possible to load a website within a reasonable amount of time..
Wifi works.
Stock and cm13-caf firmware show the same behavior.
Like shown in the photo the phone is successfully connected to a 4g/lte network.
Phone calls on a 2g-network work.
Any ideas to which component we have to replace? Or any hints on what could give more information about the actual issue?
Thanks in advance!
Best Regards
Michael

Does the original screen still work? If it does, you could try moving everything back to see if that makes a difference.
When you replaced the screen, did you use a where the LCD/frame/glass were pre-assembled?

Thanks for your response.
I had two replacement displays and noticed the same issues with both of them.
(I bought a cheap one first from ebay which had multiple touch screen issues and only after that bought a way more expensive original replacement unit.)

Hmm, hopefully, it is not a motherboard issue. I would suggest trying the old screen is possible.
Another part that may affect signal would be the USB flex port cable. The other pieces that attach to the motherboard are the camera, headphone jack, USB charging/data cable, and battery.

We completely destroyed the old display unit after removing all other components except for the battery. This made it easier to bend it and remove the battery without damaging its enclosing.
I'm afraid it might be the mainboard but was hoping for a cheaper solution . The usb board is still a possibility since it routes a quite a few signals between components.... Are there some schematics of the device available online?

Haven't seen any schematics.
I guess you didn't use a hair dryer to warm the adhesive before using a spudger to remove the battery.
Examine the USB flex cable to see if there are any breaks.
If you get a phone with a smashed screen and working internals, you should be able to get the phone working.

I wasn't sure if heating up the battery is a good idea and since the old screen has already been damaged I really didn't care if it's even more so...

Heating the battery is fine as long as you keep moving the hair dryer around. The battery just needs to get warm, not hot. Also, you would heat it from the front of the phone, not the back.

I bought a Nexus 5 with a damaged display unit online and used its mainboard and antenna cables to fix my unit. Everything works again. Seems to have been something on the mainboard but I have no idea which component exactly.

Thanks for updating the thread with your solution.
