[Q] Phone freezing after phone call ends

Wanted to see if anyone else has experienced this problem and if there is a solution. There are some other posts I found on this problem but on different phones. I can't believe I'm the only G3 owner having this problem. About half the times I receive or make a phone call, after the call ends, phone becomes completely unresponsive for about 5 to 10 seconds. Can't swipe to next screen, nothing. If the other person ends the call first then I'm stuck at the dialer interface. I can't even reboot the phone. I am rooted with IOroot and using Titanium backup and have frozen all the AT&T bloatware and some LG apps. I finally put Apex launcher on phone hoping this might solve problem. It has solved all remaining laggyness but still having the problem with freezing after phone call ends.
I have Exposed Installer and G3 Tweakbox installed. No other modules installed and this has been happening since before rooting.
I added screenshots of all the apps I froze withTB.
If anyone has some ideas on what I could do to solve this I would appreciate your help.

I've got this problem as well. Touchscreen being unresponsive after someone hangs up on me. I have no solution tho just looking for an answer myself. Only way round it for me is a battery pull but would be nice to know how to fix it.

Someone has told me why on Google +, well it will fix it for me. If you have disabled knock on/off and your on a certain firmware it is a known issue that the touchscreen becomes unresponsive. So hopefully you are in the same boat as me and you just need to enable knock on.

Thanks p70shooter. I did disable the Knock on feature, comes on in my pocket too much. Maybe this will be addressed in a future update as well as the freezing issue. I will give this solution a try and see what happens.

I am using H818N , and there is some issue with my camera and cellar.

I just buy a H818N two months ago. But some issue happened , I can't access my camera sometimes. And when it happened I noticed that my network also has some problem. The signal always unstable .
But this is issue happened only few times , but I have completely no idea what it cause.
I just try to flash my device with KDZ but I am not sure if it will work.
Anyone knows anything about it?

Never happened to me, but seems like what you're doing is the best route. Which rom were you on? Maybe check in with rom-specific forum/thread.

it happens also in official rom,no apps installed,standard settings,so i guess it s a hardware problem:crying:
something wrong with the screen maybe(which is working in every touch,everywhere else,just freezes in incoming calls)
i ll try to find another way to accept calls.intelligent gestures,maybe with power button
i will search for apps for alternative way to answer calls.
if anyone has something in mind please post it here:good:

Sound Issue: No internal speaker/No microphone/No sound by bluetooth

Hi guys,
Im here to speak about my mi 10t who got some sound/mic issue.
Everything was working good but one day, the phone muted himself on stock Rom.
When i tried to use the tap recorder, the app said "verify if an app is using the microphone an try again."
I try to put a Custom rom on it but it's the same with Lineage Os.
Now, internal and external speaker stoped working. Microphone too.
the bluetooth connect well to a device but when i play a song, no sound happen.
Even on twitter or reddit, when i tried to play a video its say, Error to load the video.
When i tried to call someone, the app close immediately
I can only send sms and read them.
Please helps
Hello,
I have the same problem just like you 1 month now,tried everything , even install custom ROMS but the problem remains.
Did you drop your phone down? I cant remember that i did , but if i shake my 10T pro near my ears i can hear that something is moving inside my device.
The temporary fix that i had was to reboot many times my device and reopen it , clear the data from phone services , but couldnt find any permanent fix though.
Does anyone else has this?

Hey!
I am running lineage and the problem is still there !
Ahah, a friend just remember me that i threw a whole beer on it during a party like 3 months ago..
I totaly forgot that and i think i was too drunk to remember.. unfortunately!
But the phone is like new and nothing is moving inside
Yes if i reboot/wipe data 363637x time it has a chance to work but the problem come back fast
I use a second phone where i put my sim on it and play with the mi10
It's sad because that 144hz screen is fkin good
And i still can't Say if it's a software or an hardware bug.
Because if i open the phone, change the internal/external speaker for nothing i will be a bit pissed
But still a good phone even muted aha

Hey,
Thanks for the answer.
I had a similar accident as well . My question though is what causes the sound issue. if i try to reboot/wipe this (which i dont want to wipe all my data every week ) there is a change also for me to work.
Do you have any idea how can i fix this ? should i give it to somebody who can open it for me as its a hardware issue?
I have the same problem, has anyone found the solution?

Entirely unrelated to the issue, but just to calm some folks
The Mi 10T Pro model rattles because the camera has OIS (the camera module itself moves). This can also give a slight rattling effect when playing very loud music
Don't worry about it

Try to open the phone x50 times and dont let it close again....This is the only way that i found out , but cant/ dont have the time to switch it off x50 times.
same problem here...
i've dropped my phone one time and after that, no sound at all.
the assistance shop said that all the components were good, but the problem remains
my last try was to flash the xiaomi stock rom, but no results
Had a similar issue.
Even multiple factory resets also didn't help.
However tried another sim and did a reset and it was working fine.
Now then after few days it again happened
Now this time I probably understood what was triggering the issue. I had paired my headphones(Bluedio Turbine) with both my laptop and phone. Using one at a time it was working fine. However if there's a call from both laptop and phone then the phone went into this state.
Again tried resetting multiple times. This time tried replacing the sim with a different sim. Different from the one in previous attempt and the sim change trick also did not work. Then tried again with the same sim which had fixed it earlier and it worked.
So in short these are the steps that helped me. Seems like only sim might have worked however don't know for sure.
Take proper backup of your data. Also this may or may not work for you.
Factory reset from settings.
Shutdown phone.
Press volume up and power button and hold them for some time till the phone starts up.
Use power button and volume key to wipe data.
I did this 3-4 however I think so it is t required.
Replace your sim with another sim. I had replaced my Airtel sim with a different Airtel sim and it worked for me. However replacing Airtel with jio did not help.
Start the phone.
Setup the phone.
Phone might start behaving fine.

Ignore this. This again happened after the last fix. Now again I can not use the mic. In CIT check if I try to test any of the mics, top or main the app crashes. Seems to be related to the mic. However don't understand how come event Bluetooth calls fail.
Another thing that I tried was putting the phone in refrigerator for around 10-15 mins. The phone was switched off before being put in the refrigerator. It generally works after that.
However it is generally good only till a restart.
Try at your own risk.
Must be something to do with the firmware only. And problem seem to be happening at the time of a reboot. Right at the time when MIUI logo appears during a reboot, if you dont hear the bootup sound, then the system audio wont work.
What fixes for me is multiple reboots until you hear the bootup sound. Most of the time, it takes just a couple of reboot. Max it has taken for me is 7.
Problem with loading of audio driver?!
Hi all,
Is there any update on that issue ? I still have that phone doing nothing at the moment. So i was wondering if there is any chance to use it.
I have the same problem.

New Mi10T Pro - No Sound at all
Brand new device. Flashed custom OS (Arrow OS and google pixel)- no sound at all. No Youtube sounds, no call sounds, no media sounds, even Bluetooth, even with headphones. Phone are silent absolutely. Please help. Thanks in advance, guys!
forum.xda-developers.com
you may find a solution there.
I still have the error
Still same problem here. I even updated to a custom rom, but no difference. Even sound via bluetooth does not work nor sound via USB.
Anyone has a theory how that could happen?

Question [Solved] A52s 5G freezes and going back to home screen by itself

Hi Guys! I am new here, my samsung A52s 5g just freezes and always going back to home screen specially when connected to wifi. It just happened all of a sudden, I didn't even downloaded anything, I just use my phone on social media platform and some games.
Here's what I did
I tried factory reset - issue still persists
I tried hard reset, clear cache - issue still persists
I tried reprograming with Odin the latest version of Odin - still didn't fix the problem I even downgraded the android version with the old A52s firmwarw with Odin but the issuw still persists.
Does anyone encountered the same issue? And know a solution? Please let me know. TIA
Welcome to XDA
Sounds like a hardware failure.
If you did all that not much else left.
I hope someone know a solution how to fix this problem. It just happened all of a sudden. The phone was working fine beforw my son just turned it off. When I turned it back on it freezes wherever I go and going back to homescreen by itself. It happens all the time when the wifi is on. But when the wifi is off, it is somehow ok.
Well leave the wifi off. You went back to a known good firmware version and set the data user partition to its default settings. Unless you installed a buggy 3rd party after that there's not much left other than a hardware failure.
Data user partition should be in default settings I guess since flashing to known good version.

Sounds like you're having the same issue as me: https://forum.xda-developers.com/t/a52s-randomly-rebooting-freezing.4503129
When this happens, do you see the Samsung logo that you normally see when you turn on your phone?

Yes, restarting phone is fine like normal, but whenever I browse on my a52s it keeps lagging but when press the return/back button it goes back to normal but when I repeat browsing the same thing it keeps lagging, sometimes it freezes and going back to home screen.

What browser? Try clearing that browser's data.
Try a different browser like Brave.
Google chrome browser but not just on browser also in every app. Even in Settings it keeps freezing and going back to home screen

That's likely a hardware failure of some type probably the mobo.
Hello guys! My A52s is now working in properly, no more freezing/lagging. What I did is I drained the battery to zero and had it fully charged then I saw an update from android 12 to android 13. Voila my a52s is back to normal like new . Thank you guys for your time to reply. God bless us all

Time will tell. I find that disconcerting. Did Samsung release that model with that big of a glitch in the firmware for some models of that production run? Yes, well... that's Samsung.
I've had this issue. Sent it back for warranty claims and they sent me a replacement unit, Initally I though GalaxyMax Hz caused this issue - so I haven't used it again.
