Screen problem - Redmi K20 / Xiaomi Mi 9T Questions & Answers

I quess this might not be problem with phone itself, because it was fine till this day but I got some problems with bottom of my screen, as you can see on screenshot. Also, I can bring back buttons instead gestures in setting, or maybe I just cant see buttons because they are below edge?
Google didn't help me, so I am trying to find solution here.
Thank you.
edit: when I switch back to buttons not gestures, screen is normal but there is no buttons.

you have custom launcher, just try go with stock and see what happens

Incorrect response from touch screen

Hi there!
I have absolutely ridiculous problem with my THD. All of a sudden screen started to act like it is half disabled. In simple words, if a touch some icon on top bar, let's say Start button, click appears on clock. Basically it is looks like touch area displaced by half an inch down. I've tried to calibrate screeen and it seems like it worked for a few minutes and then turns back. I had to hard reset the whole thing and it did not help either. All images, icons, screen items appeared correctly on screen. Bottom menu bar responses correctly though.
I did not drop the phone if it will give a clue.
Anyone knows what the hell is that and how to fix that problem? Please help.
Thank you.
Anyone? Please...
sounds like you need to re align your touch screen. you need to go to Start>Settings>System>Screen then align screen
If you cant get to this then a Hard Reset might be the only way to go
Nothing is working. Now I cannot even get past screen alignment. Looks like it can be a hardware problem.
u may have to hard reset
then after that if it still wont work then u may need a replacement
Yeah. It sound like it is. Jast called HTC support, did hard reset again and after few minutes it is back to that misalignment. Damn...
Connected to ActiveSync and have you got 'My Mobiler' running? I noticed some strange screen behaviour with that on the Device and the host PC.
try pressing both volume keys and tapping the screen at the same time(volup + voldown + tap the screen) --- it will get you to align screen mode if that doesnt work then maybe you have some problems while flashing a rom or something!

I am having the same problem, it started suddenly somedays ago. I realized that when I hard rest it works fine for some time and then slowly left side of the screen stops responding, after a while only right side react to touch so you cannot access START menu nor anything else from the whole screen, just the left corners.Any solution?

On screen keyboard mode switcher button problems

This is probably going to not get any responses as most people aren't using the on screen keyboard, but I'll post it anyways.
Has anyone's on screen keyboard had the mode switching button break? This is the button in the bottom right that lets you switch between full keyboard, thumb keyboard, and transcriber. When it stops working, the icon disappears. If you click it, the key turns white and stays white and does nothing.
I don't know what causes it to break, but once it's broken, I can't get it to work again. It seems to be user-account specific. It works fine on other user accounts I create, but once it breaks on one account it stays broken.
this happens to me too, ms forums only ever says refresh your pc, that work for less than a day, hopefully it is fixed by beta

Display "home screen" on second display

Hi guys~
Unfortunately I dropped my yota on concrete ground and the main screen is not working anymore before a new phone arrived, I need to live with it for a little while, with the second screen.
Most of the time it serve the purpose, email/chat/calls, but I'm unable to get to the home screen to open my apps. Its strange enough it occasionally get me to the home screen, I remember one time I use the back button(the triangle) on a setting screen, or the home button(square) on wechat or simply swipe up on messenger, it brought me to the home screen, but never again no matter how hard or how many times I try
Do you guys know is there a way I can get to the home screen on the second display? Much apprecaited and that will definitely prevent grey hair growing on my head! Thanks in advance!!

Slide up left long press the home button wheel to activate yotamirror, it's then the left icon choice of three option.

Moto X Style On Screen buttons not working

Some basic info before i begin:
Phone: Moto X Style/Pure on android 5.1.1 (XT1572)
It is rooted, but no custom roms are installed.
So basically what happened was I dropped by phone, then all of a sudden the on screen (Home, Back and Multitasking) buttons started to become unresponsive and started ghosting. I have restarted so many times just to exit an app. After several restarts, my on screen (home, back and multitask) buttons have stopped working.
Firstly my basic and short term solution was to install a 3rd party on screen button app from the play store, this would put a second set of on screen buttons above the stock on screen buttons. But before this I noticed that the on screen buttons actually worked when rotated so that instead of being on the bottom of the screen they would be on top. The on screen buttons also work when i boot into recovery mode, my custom recovery is TWRP. I also wiped dalvik cache and reinstalled my apps through the recovery setup.
I dont know whats going on, I even made it so that when my on screen buttons moved to the top of the screen, i would click on apps from the bottom of the screen and it would work. It doesnt seem to be a hardware issue as i have confirmed it to be working through TWRP and tapping on apps from the bottom of the screen, confirming that my touch screen is working perfectly. The on screen buttons also work and it being detected when TalkBack is enabled.
Help me plez.
Common hardware problem, use developer option to see your input and tap, if it brake when on nav bar, then IT IS HARDWARE PROBLEM.

Hi, I enabled Show Touches in my Developer Options and when I put my finger on the actual nav bar, the pointer stops just above it.
Idk if its a hardware problem, but i did drop it. And it still works in TWRP and TalkBack enabled.

The touch screen issue of this device is hardware related, born with such flaw, you will have it even you didn't drop it.
No sure how it happened, but it helps if you can take it apart and clean the connector a bit and make sure you reconnect it firmly, if that doesn't work, you will have to replace the touch screen part or the whole screen and touch screen and rear frame and stuff, but do notice: it's likely to happen again.

HELP! Can't get past lock screen (Pie Stable)

I was on official Pie beta (which worked excellent for me) with locked bootloader and today morning I got OTA for Pie stable. I thought what could possibly go wrong and updated it.
After updating successfully, On lock screen, I swiped up to enter my password, and it just showed me black screen. I tried various ways to go past that black screen. Nothing seemed to work. I tried reflashing Pie BETA zip from SD card in recovery, but that also failed as it showed error that it cannot flash old version when on new version. I don't want to factory reset as all my important app data will be gone. I can't even set the USB connectivity behaviour to MTP as selecting that option also shows me black screen. I am able to use camera and google assistant directly via lock screen but when trying to do anything else it shows me that black screen. I tried clearing cache from recovery, but that also didn't get me past that black screen. I can receive calls but can't do anything else. Even Whatsapp Web is working but I cannot open Whatsapp from my phone. I can't afford to factory reset as all my assignments are there in an app.
My last bet is to wait for someone or Asus to post Pie Stable zip and then reflash that zip from stock recovery via SD card.
If someone have any solution or has suffered from similar problem, please help
Hi,
I was also facing the same issue after updating to android Pie.
Here is a way around, using which I was able to access the phone.
Press power button.
You will be able to see the lock screen.
On the bottom bar, you will be able to see buttons,
on left, mic
in middle lock
and on right camera.
Swipe mic button, it will open the google assistance, however, it will ask for unlocking the screen.
Once you unlock this screen, you can go back to home screen.
If all go right, you will be back on your home screen and now your lock functionality will also be working as expected

Thanks for answering
Entering password on that black screen also works.
Simply switch to a dark wallpaper instead of a light colour wallpaper.
