Did the issue fix itself?
I am encountering the same issue and looking to know if it is a phone thing or an update issue.
I factory reset the phone but the issue is still occurring.

I tried downgrading to 12.5.3 but it didn't work. Seems like roll back is prohibited at my phone.
The issue stopped occurring for approx 9 days and yesterday without doing anything it started reoccuring and has not stopped since.
The issue keeps reoccurring even in safe mode.
I am totally confused. I don't know what to do

The same issue with mine also after updating to 12.5.4. The phone can't be used while every 2-3 minutes disconnects from network. Any ideas?

Bluetooth turns off when restart phone

It seems whenever i reboot my phone, bluetooth would be off when the phone turns back on.
Currently running stock OOS 4.0.3 rooted , I dont recall having this issue when I first got this device, it started happening recently.
Is it a bug with 4.0.3 or is it just me?
This happened to me a while back too. It started after I updated Nova Launcher though the Play Store for some reason. Dirty flashing OOS 4.0.3 fixed it.
I have the same issue. I'm unfortunately a noob and a fiddler and have had to restart my phone a few times in the last week. I only realise that the Bluetooth is off when i don't receive notifications on my watch.
I'm currently downloading OOS 4.1.0 and hope this solves​the issue.
I've been installing the upgrades to the stock OOS and today I installed the beta 4. My bluetooth still turns off after restarting. Any solutions?
I am currently on 4.1.0 , seems the issue is resolved for me
Open Beta 4 does the same thing.
I'm still facing this issue on latest OP3T OTA update
I had the problem coming back after updating to OOS 4.1.3
I cleared the cache and it seems to be fixed, tried rebooting several times and bluetooth remains on

Phone reboots itself when loss signal

Hi. My phone keeps restarting itself when the signal lost (Examples: out of lifts, basements and etc). I've updated the firmware to the latest one, V40 and already even try the previous firmware V37. I'm having this issue when using custom rom and even Miui stock rom. Does someone having the same problem with me?
I think the main culprit have to do with the phone trying to search for signal and it goes into a power cycle.
Thank you.

Solved: New WiFi Authentication Problem Persisting after Factory Reset

Hey Everyone,
I have a T813 (9.7") that's about 2 1/2 years old. Over the last week, I've seen the "Authentication Error Occurred" in my WiFi settings. The easiest way to resolve it temporarily has been to turn WiFi off and on again. That lasts for about 10 minutes before I need to do it again.
I've Googled around and tried a number of solutions, including a Factory Reset. The tablet is stock with the last software update Samsung released. I'm thinking about reflashing the factory firmware or trying a Lineage or another ROM to see if the issue persists.
Has anyone had this issue before? Has anyone resolved it? I'd rather not replace the device over this dumb issue.
Thank you!!! ❤
The WiFi began behaving normally again after flashing the stock firmware with Odin.

Sony XZ3 Android Setup crashes

Hi,
I have a big problem with my xz3. I flashed it multiple times via Newflasher but right after startup there is the fault Android Setup crashed. Wait or end. I wait and then it continues but WiFi is not found.
Before the problem occured there was a ota Android 10 setup. Also I dropped the phone accidentally. It worked a day or so and then the crashing startet.
Is there a way to wipe everything and get this phone to life again.
Thanks
( I don't know if this is the right forums. Sony forum is a bit empty)
I'm currently facing the exact same problem
The phone randomly crashes and reboots in addition to the wifi and signal drop issues you mentionned
I have searched everywhere but haven't found a solution to this
Has anyone found a solution to this ?
I tried to reflash it with xperia companion and multiple stock versions with flashtool, some checking wipe everything, still no wifi.

Question Device freezing in MIUI 13 all versions and variants

After updating to MIUI 13, I randomly have freezing issue (when scrolling tiktok, playing game, watching youtube, etc.) which sometimes fixes if I wait and the system shows notification of "The *app* stopped working" or something, and many other times I can only force reboot the phone (by holding the power botton until it reboots).
The issue never occured on MIUI 12, only on MIUI 13 from the first version untill now. So overtime I downgrade the ROM or change it to other variants such as global version (the issue also occurs in other country's variants of MIUI 13), hoping that the bug is fixed everytime there is a newer version of MIUI 13 of Indonesia but it's never been fixed.
I report many times through the feedback and service but they only suggest to keep the RAM and memory managed, and to charge the phone in time, which don't solve the issue since I have plenty of internal memory space available and use the phone the same when I'm on MIUI 12 (also how the hell do I charge it in time?!).
Does anyone have this issue as well? And how do you fix it other than to downgrade or to change to custom ROMs? Is it better to wait till MIUI 14 comes out than to downgrade it again? Sorry for my bad English.
i have the same issue though, I'm still hoping an update for this kinda issue because it's really annoying. I'm not sure for install custom rom will fix it, or it does.
I ever thought that downgrade is the only way to do, because when I use miui 12 I didn't get any of bugs and issues.

MIUI 13.0.8 just came out a few days ago for my region, but I won't upgrade it at least until MIUI 14 comes out.
Installing custom rom does fix it. I tried Pixel Experience once and never got the bug, but I didn't quite like the overall appereance so I decided to just downgrade it again to MIUI 12.5.5.
Yes. I have had this EXACT same issue, too. factory reset did not resolve. Redmi Note 9 Phone is all but useless now. Can use for a few minutes at a time, before it freezes. Miui 14 should be around the corner now, but I'm not hopeful.

MIUI 14 also does not resolve the issue for me, so downgrading is the only solution (not even MIUI 13 and 14 based custom rom fix it). But some people from RN10pro forum got it fixed after a few updates. Here are some suggestion I got from there:
1. Check if your SD card is dead, simply replace it or take it out.
2. Change your system to light mode.
3. Disable the memory extension.
Some people got it fixed after doing one of the above suggestions but not for me.
