I am facing a problem where my home button is not working and and no notifications can be seen . I just kept my phone on charging and it rebooted and stopped working . Please help
The best what I can suggest is - do a factory reset. But remember, you will loose all your apps and settings.

Status bar + background disappearing problem, Loop

Hello,
I'm facing a weird problem, that after booting into Mi A1,
Status bar & Background wallpaper, would disappear & appear every 3 seconds.
& this continues in a loop.
I even tried flashing "Full stock October build" to both slots a & b (while selecting "save user data").
but the MiFlash Tool, gives an error "Flash modem_a error".
I will appreciate, if someone can help me out here.
As i can't use my phone.

I disabled lock screen & Ambient display,
as well as flashed stock boot images of September & August builds on their slots.
After doing all this, i could straight away go to homescreen.
But still the background of homescreen keeps on switching between black & the status bar also disappears,
then suddenly, wallpaper & status bar appears.
When i click search bar, to type something, keyboard appears. But immediately disappears due this background+status bar flickering/resetting.
Can anybody help me in fixing this.
First post edited.
It seems like constant system UI crashing. I experienced it once with Nexus 5X after doing some system modifications, the only way how to solve it was to perform factory reset. Reflashing of system only strangely didn't help at all.
Had to clean flash stock rom via MiFlash Tool.
Took me 5 hours, to copy files & setup phone again.
Even i had this problem
I some how managed and went into settings and performed a factory reset
The problem vanished

Same problem here, it was Causing because of whatsApp, Solution Turn off Ambient Display,
I Did Hard Reset, By Power off and Volume keys,
If You can Reach to the ambient Display settings without Reset try to turn it off, as phone works for few seconds after re-start.
Mine is Working fine after since I turned Off Ambient Display,
Got this Solution from Other Thread, Thought to Help others.

Black screen, bootloop, restarting

After successfully installing the official Oreo Update for my Samsung Galaxy s7 edge it suddenly started freezing up randomly and restarting itself, at first I thought it was not a problem, but it got so big I can´t even start my phone anymore, and yes I have tried everything except Odin, reset it manually, wiped the cache, and now I do have a blackscreen with my LED sensor blinking in blue and my touch keys lightning, I have no clue what to do, since my phone doesn´t react on anything anymore, neither the on/off button, won´t let me get into the donwload mode either, anything I can do to fix this? about to despair
