S21 Exynos mobile service not working - Samsung Galaxy S21 ROMs, Kernel

Hi everyone, i have recently flashed the pixel experience 13+ gsi on my s21 and for some reason the mobile data just doesnt work correctly. First it connects for a few seconds and it works, then it
turns into "No service" and after a few more seconds it turns back on and the cycle repeats. When trying to
enter the mobile data settings while its glitching it just lags really bad and crashes the settings app.
Everything works perfectly fine, except for just the mobile data.. Anyone got a fix?

Try to reflash the room with a clean flash, I think something got wrong. I'm on the same rom with the same phone and I don't have any problem with mobile data. 5g is working too. Only the signal bar is shown empty but the phone is connected.

Hello, I'm thinking about to install this GSI, how's going with it?
What camera app do you use?
Some bug or something broken?

Hi, well front camera not working with Google camera ports and no real 5g. You can force 5g dialing #*#*4636*#*# and selecting NR only in network menu, but it enables a faster LTE showed as 5g.
I miss encryption too using twrp, but I'm facing to solve this, using a patched stock recovery with fastboot commands enabled as soon as I find a way to do this.
Bluetooth, double tap or fingerprint can be solved easily in pph treble settings.
Everything else is really good, I don't like OneUI. What I like being on gsi is fluidity and very fast response too.

Issue with mobile data connection

Dear all,
I own a OP6 always updated through OTA. But I have a big problem: often, and without noticing it, the data connection is interrupted and the only way to reactivate it is turn off the connection from the menu, wait a minute, and reactivate the connection. It happens several times a day.
As you can imagine, it is a big problem because someone sends me emails or messages that I do not receive until I do the steps above. And I don't know when I'm connected and when I am not because everything seems okay.
Can you help me?
Thanks in advance.

Just out of curiosity, did you try downloading the latest full rom and flashing it? I was always having issues with severe battery drain if I updated by OTA. Downloading the rom from OP website and flashing fixed the issue. Could be something similar for you.
Be sure to do a backup first incase of any problems.

Not similar but this the only case. I learned it through 4 devices OTA updates always mess up something. Always do full clean install, i know it sucks to settup the phone again install backups.. etc.. but it gor good
I think i have the same problem but after every reboot. I get 4G icon, but there is no connectivity on chrome and other apps (although Spotify seems to work). Only after switching to 3G and back to 4G the data works...
I had the same problem on my OP3 in OOS, but not in Resurrection Remix... really weird. I may try Havoc OS to see.
No problems with mobile data here, but dame issues when on wifi. I did a factory reset yesterday and clean install, but sadly that didn't help.
I've just updated to OxygenOS 5.1.11 and the issue is still with me. How is it possible? It's a really annoying bug. Developers, where are you when we need you most?

Settings - Back up and reset - network settings reset
Make sure you reboot your phone once after you do that
Does anyone know what the best apn and network settings are for an unlocked Moto g5 plus on metro by TMobile
When I use OP6 on mobile data, cant use google or associated programs... Used a VPN program and problem is solved.
Updated: deleted all APN and insert manually APN for my network. Works just fine...for now.

Bluetooth settings crashing on OB12

Any fixes? It keeps crashing and reboot doesn't fix it.
Open "Beta" build. Expect bugs. Also there's a reason this build is pulled back by OnePlus. Downgrade to OB11. Everything seems fine to me on OB11.
No issues here on OB12

Anyone has fix this Bluetooth issue in ob12?
So it's still not fixed in ob14
Has this issue just yesterday in OB14. Sudden freeze and reboot. After that Bluetooth settings crash, no lock screen and theming worked buggy. Took a backup and clean flashed. No problems so far
Hello,
I had the same crash with stable 9.04 approx one week after upgrading from 9.0.3.
Suddenly, entering bluetooth made settings app force close.
I couldn't find any solution and ended up to factory reset the phone...

This happens for me every two weeks... I don't know at all why it happens. I'm thinking it could be caused by the navbar gestures, SwiftKey, cf.lumen or maybe kinscreen. Do you use one of these?
I went back to 9.0.4 because of that and it still happens.

Sorry but i use none of these. In my case the rom starts to collapse itself after a few updates dirty flashed. Some system apps not showing on ocasional boots, some sudden soft reboots and then lockscreen not showing at all, theming bugs, and Bluetooth crash. I take backup using oneplus switch and titanium and fresh install open beta, restoring all doesnt take more than 20 minutes.
My bluetooth setting crash, i couldn't connect any new devices. so i searched for solution in this forum. im on OOS 9.0.4. just before i take the plunge wipe data clean install rom, i tried the following.
I first cleared Setting App cache and data, didn't work.
then i gone into recovery and cleared Dalvik cache, didn't work.
then i used Clean Master and cleared system cache, 3gb worth, and bluetooth setting worked again!
hope this helps someone in the future.
Hello guys, i just noticed that bluetooth settings crashing ,everything was working fine for me (as long as i remember), but yesterday i was trying to pair a BT controller and it happened. So let me explain, turning on and off bt affects nothing, but when it's on and you try to go to the settings by long tap on quick settings or by the settings it crashes. when it's off you can go to the settings but once you try to pair a new device it crashes, old paired devices pair when you turn on the BT so it happens only when you try to pair a new device.
I tried to go to the 9.0.6 but it was crashing there too, so i rolled back to OB19.
I'm rooted, magisk 19.2 and twrp and with stock or smurf kernel it crashes , so i ended up pairing the controller with a third party app.
I'm sure it was working before because i paired alot of devices. I tried some "fixes" like freezing the bttestmode or clearing the cache and data of the bluetooth but none of those fixed the issue. So did anyone find a solution.
Thank you
For everyone having BT crashes, try looking at your phone Bluetooth name and check if it's blank. Usually happens to me when fsync fails and I lose my ram data.

OnePlus 7 pro wifi problems

Hi guys, I got my OnePlus 7 pro at the time of release, and up to now it's been through all of the updates etc. But I have a major problem with using WiFi. Sometimes it works normally, but other times, images won't load, or downloading images from apps such as WhatsApp takes forever. Images such as profile pictures don't load either or will take a very long time. However watching video on YouTube etc is all fine. I'm very confused at to this issue and wondering if anyone else knows anything about it.
Thankyou!
By the way, using mobile data works fine and everything loads properly.
I would recommend factory reset at this point. This beast is fast as hell on wifi. No issues here.
I've also had this issue sometimes. It pops back up every now and then but what fixed it in most apps was going into router/modem settings and make sure that the time(what tells the router your local area's current time) is being controlled by your ISP and not by the internet.

Thank you for your response, yeah the 7 pro is a beast, but i doubt that a factory reset would help

Thank you for your reply, i will try this and see if it works. I'm still unsure about the cause of this issue, and i really hope its not a hardware issue. I never had this problem on my OP3 which is quite sad

Calls not connecting on AOSP ROM

Just flashed Resurrection. Everything is cool except my calls don't connect. When I dial, the call immediately ends. If I toggle airplane mode a few times the call will finally connect. I figured this is an AOSP thing. Does anyone know of a fix?
Metro pcs is my service provider by the way
Bump.. been checking around and I've found nothing. However I'm able to dial Google voice numbers without issue

I know a fix, but you're not going to like it. Flash something else. See if the problem persist. If not, boom, problem fixed. If yes, make a log. Post it in the ROM thread together with problem description. Wait for fix.
edit:
If the same problem persist also on another ROM could be also HW problem.

I actually love flashing new ROMs lol. Unfortunately flashing a different rom didn't help. Same thing is happening. I ended up flashing Official Android 11 Pixel Experience.
At this point I'm sure it's an AOSP thing or custom ROM (don't think it's HW atm). When my bootloader was locked for the "168 hour" wait period I was able to make all of the outbound calls I wanted. I'll post some logs in both threads just for the record while I continue to find a fix.
I've found a workaround for my issue. I installed an MIUI ROM. I've been able to make calls without issue.
Not sure why MIUI allows me to dial out and AOSP doesn't. If anyone can chime in, that would be awesome. Otherwise I'll rock with MIUI ROMs for the time being.

Pixel Experience hasn't been updated for a long time if I'm not mistaken.
I personally use ArrowOS 12.1 and have no issues. Even automatic call recording works for me

I was previously on awaken os android 13 version.I noticed this call problem when I was on that rom.So I shifted to pixel experience.
But I just turned off Volte toggle and now calls are seems to be working.So could it be issue from my network provider side?

To be absolutely sure that it's your provider's fault, I would probably also flash MIUI to be 100% sure

Will any miui based rom work?Like Eu rom?

Question Every custom ROM used receiving call goes down after 30 seconds.

Hi, would like to ask for some help to the community because every ROM i've tested, Arrow, Pixel Experience, etc etc i have an issue regarding receiving calls. When someone calls me, after 30 seconds call goes off. If i am the one who calls, all seems fine.
How can i make a better report for what is happening to me? I have no idea why this happens.
Now i tried ACIP ROM, and the same happened. Just after a clean install, the only ROM that this doesn't happen is MIUI latest. I am completely losing hope on using custom ROMS. Would love some help to log or whatever.
Is 30 seconds a time to screen off?
I observe similar behavior in Lineageos, but it is only screen off, not disconnect.
No, just the call. between 20 - 30 seconds it just disconnects.

Wifi calling caused my phone to double call, it would call hang up then call again.
Maybe its a network provider issue?
Have you tried format data and also if you use Wifi calling do calls get disconnected ?
I dont use wi-fi connection.
Strange that Miui works fine. Is there a way i can make a log?
still having this issue, any thoughts on this? how to debug it?
have you tried using other cards or networks?
@OP - is the phone still under warranty? Sounds like a hardware connection problem.

Bruh that's weird, i've never experienced apps like this going ape crazy in the long run of me installing ROMs from here in XDA. Everything works fine except in all the custom ROMs
Ever tried to backup that "working" phone app and installing it on the custom ROMs?
Not sure if there's a way to log that event if ever you want logs to be saved and documented for troubleshooting.

Set Filter for errors, save output to file and analyze on a another device or try live? You could try to call somebody with speakers enabled while watching logcat
edit: forgot to mention - settings->buffers release don't stupidity
