Android 9 WiFi problem apps.. - Samsung Galaxy S9+ Questions & Answers

Hello, since I upgraded to Android 9 the problems with the wifi started after leaving the phone for more than 15 minutes without occupying the notification of any type related to wifi, such as whatsapp, telegram or faceboock or others, by unlocking the phone. and enter some of those applications just shows me all the messages that arrived, that does not happen if I leave activated only mobile network and disable wifi, my model is sm-g9650. Already probe restored factory, installing another rom and the problem continues. I returned to Andriod 8 and that does not happen, it is only on Android 9. Someone with that problem? Thank you

[Q] Some "Null" Wifi puts phone into loop reboots

Had no issue with my S6 edge for the last few weeks i have it, except the common RAM problem.
Suddenly, Since today only ( i didn't do any fw updates as i'm pingpong rooted and thus have no OTA).
Problem :
Whenever my Wifi doesn't see any known Wifi around (=wifi i previously connected to), it will show me a notification saying "Sign in to Wi-Fi network" : Tap here to sign in to null
very few seconds later... the phone restart by itself, and same problem happens again and again with infinite rebooting (unless by luck i manage to quickly deactivate the Wifi early just before it reboots again, or it detects a known wifi and connect to it.)
In other words : infinite reboots trying to connect to a non existent Wifi null that would require a sign in...
Any help appreciated to know what suddenly caused it and how to solve it ?
THANKS
note :
- it happens anywhere, at different locations (so there is no strange wifi around me).
- last thing i did with my phone is going to developer options and put the "limit background processes" to 4 iso the standard limit. (trying to fix the famous RAM issues). But when going there now, it's back to the defaults "standard limit" anyway, so i don't think it's related.
- i'm pingpong rooted, have Tasker, Secure Settings, etc...
-Edit: message erased -
I thought I v found a fix but I was wrong.
Anyone else encounters this bug??

wifi problem

Hi, after the last update it often happens that when I am under wifi the notifications do not arrive. the wifi does not disconnect but above all whatsapp notifications are not received. I remember that there was an option on android 8 "wifi always on standby". On android 9 there is not and I think it should be an optimization problem. Can you help me? I have already put whatsapp among the apps not to be optimized. thank you

Random Reboots and cant access Advenced Wifi and App-Info Settings

Hi there,
since two days iam experiencing super weird errors with my Pocophone F1.
First it restarts totally random. Put my finger on the scanner to unlock it... the Lineage Logo appears.
I want to use my microphone for voice messages in whatsapp... the Lineage Logo appears.
These are random af..
Some lesser random reboots are happening, when i try to connect to any local wifi or toggle my wifi on and off OR if i turn Aeroplane Mode on/off.
The even more annoying stuff is that i cant(!) get in the following options:
Wifi-Settings under Network & Internet; all settings about Cellular Network, and App-Information- App (all the detailed Informations on one specific app in Apps & Notifications)
within Settings.
Everything else still works like a charm.
What i have tried so far:
Wipe Cache and Dalvik-Cache.
Start in Safe Mode.
Update to a more up-to-date Version of Lineage.
Reset all network settings. (yes, i was very frustrated yesterday.)
Nothing helped :/
Is anyone else experiencing this kind of bull****ery lately?
Iam running:
Xiaomi Pocophone F1
Android 10
LineageOS 17.1-20210123-NIGHTLY-beryllium

Question Mi 11 lite 5G with Galaxy watch - problem

Hello everyone
I am having Xiaomi MI 11 lite 5G and Galaxy Watch. I am having problem with losing bluetooth connection between them. I searched a lot of forums about this solution but without any luck.
I’ve already tried resetting and reinstalling everything. I’ve set the settings for all three samsung apps to autostart and disabled battery optimization for them, also made an exception in the security memory cleaner app.
But the watch is constantly losing connection. It is interesting that one day he works normally, other day he constantly loses. The loss of a connection becomes more frequent, as if it is getting worse.
When i open galaxy wearable app it says reconnect but nothing happen so i have to close app disable and enable bluetooth and then open app and connect.
I doubt there is a problem with some application because when I disable / enable the bluetooth, watch vibrates again to signal that the connection is lost, although it already has a lost connection icon on the watch.
Does anyone have similar difficulties or a solution to this problem?
Just updated to miui 13 and I also have a gear 3 watch, experienced the same issues but after update haven't found a single disconection, I'm using xiaomi.eu miui 13
Thank you for your reply.
Last week I updatetet to xiaomi.eu miui 13.
Now everything works as it should.

Infinix Hot 12 play

I recently bought Infinix hot 12 play which has 4gb + 3gb RAM. The problem I'm facing is when I open the phone 2 to 4 minutes after locking it, all the apps are killed, even wifi has to reconnect. I've turned off battery optimization. Given access to auto-start and tweaked all related settings but it isn't working.
In the first week the phone was working fine but now it's become a very serious problem as whatever you were working on is gone after you lock and unlock the phone after a couple of minutes. Please help!
Better install the stock firmware to fix the issue.
Download the Stock Firmware, as per your model, from https://firmwarefile.com/?s=Infinix+hot+12+play
Then use SP Flash Tool V5 https://spflashtools.com/windows/sp-flash-tool-v5-2216 to install the firmware.

Hey, I am having issues with the wifi disconnecting, high signal oscilation and the option "automatically connect to wifi" turning it off on it's on. Did you find any solutions to your problems?
Are there custom ROMs for the Infinix Hot 12 Play (X6816C)?
I'm having problems with lags when using the device.
I made this telegram group for the HOT 12 Play: https://t.me/+ce5nC9E1engzZjA0
I have made a stable TWRP for this device and made a modded stock
