Well in principle the problem is not the proximity sensor. The problem is with the 360-degree light sensor embedded in the back of the phone under the camera flash, which interferes with the proximity sensor. You can test that the screen turns off when you play and touch by placing your hand on it. I hope Xiaomi solves this problem

I referred this issue to the company and it was not done after a few months. It is better for the company to deactivate this 360-degree light sensor on the back cover so that it does not interfere when in contact with the proximity sensor.
This isn't right. Nothing happens when you touch that, it is only camera microphone

There may be no interference problem on your phone, but there is a light sensor embedded under the camera flash. Search the internet and you will find.
When I call on speakerphone even if I don't touch that sensor/microphone but I hold the phone vertically the screen turns off, inversely if I call without touching that sensor but the phone is in landscape the screen doesn't turn off. The screen turns off only when you start the call, in fact if I start the call in speakerphone with the phone in landscape and then I put the phone in portrait the screen does not turn off (always without touching that sensor).

Yes, that's right, the sensor only works in reverse mode and in horizontal but suspended mode and the screen is down.

Few days ago i drop my phone and broke screen, i ordered a digitizer with lcd display, it has two connections to mother board, one for digitizer and one for lcd display,
after i installed new component i boot the phone, nothing appeared, lcd seems not working. Phone functions are all OK. I can hear unlock sound. Which means digitizer also work OK.
Then I tought new lcd panel is not working. Finally by coincidence I found that if I remove the battery and plug the charging cable, lcd screen magically starts working and it looks like this:

I tried to plug the battery when lcd is working. But again it stops working as soon as I plug the battery.
So are there anyone who have a clue? Why would lcd is not working with battery? I also tried with another lg g3 stock battery again not working. And if I unplug the battery and try to wireless charging still the same yellow triangle appears. Any help would be great! Thanks!
Today i findout, if i put some flashlight on screen in a dark room, i actually see phone screen is properly displaying. So lcd display is working but backlight not working when phone bootup.
It's confusing that phone backlight also works when battery unplugged. So any ideas?

Hello Gomestai,
I have exactly the same problem.
Would you please let me know if you found a solution for this?
Thank you very much,

I discovered something on my phone. The Back & most esp. the recent App Button is not as bright as I thought, and compared with the pictures I have seen on the internet. Should I worry about this? So far it doesn't affect their main function, just the brightness is what I am concerned right now.
Good question. My wife's (top) aren't as bright as mine (bottom). Screen brightness doesn't affect them; I wonder if anything does.
I think buttons light intensity is somehow related to screen bright. If you have your phone configured to adjust bright according to level of light please put your phone near a lamp and you'll see that buttons will be brighter after some seconds.
My buttons are super bright and both equal in luminescence. They do change with ambient brightness, I keep the display on auto perhaps they get locked in the current state when switching over to manual brightness.
Ah! I figured something out: are you using GravityBox?
I was able to change the intensity of my navbar buttons reliably:
10 Enable "Always on" in Android settings--buttons are dim
20 Enable "Always on" in GravityBox--buttons are bright
30 Set to "Default" in GravityBox--no change
40 Set to "Auto off" in Android Settings--buttons off
50 GOTO 10
Button brightness changes with ambient lighting and if direct light is shone directly on it or not.
Ah! Yes they do...takes a few seconds to change but it does.
Toggling the GravityBox setting just resets the last state.
Hi Folks, looking for some help after I just about managed to replace a cracked screen & frame (I fell on top of my phone during a mountain bike descent into Glen Doll, Scotland as an aside!).
After painstakingly taking the cover, mid-frame, battery, motherboard etc out and putting them back together, I thought it was a minor miracle the phone worked again. The only issue I am having is that the screen switches off and stays off while making any calls, no matter whether I hold the phone to my ear or in front of my face.
Is this a proximity sensor issue? If so where exactly is it located and how can I check whether it's either damaged or not properly connected? Thanks in advance for any help
Sounds like it, Does you screen auto brightness work?
Its the little red sensor just under the top speaker on the right.
Nope, auto brightness isn't working either.
Do you know whether the sensor is soldered on or whether it can just be removed & replaced? The sensor seems to be in place but guessing it's not properly connected

I had the same problem as you and I think you also forgot to put the cover of proximity/light sensor.

Exactly the same problem on mine. Sadly threw away the part. Does anyone know the partnumber of this or where to buy it in Europe?
Yesterday randomly my Op3's touch screen stopped working.
From the last one year or so, there is a little gap between the mobile's display and the actual device because of the display glue coming off but nothing major happened with the phone in 1-2 days that can result in t's touch not working. I would have gone to the OnePlus service center but it is currently closed due to lockdown.
Does anyone have any idea if this means my display panel is dead or some display cable got loose which resulted in touch not working (or anything else)? I am attaching two pictures of the phone to show you guys about the display gap I am talking about.
Note: The display works perfectly and the phone works perfectly too if I connect it to my laptop and remote use it by USB debugging. Also, the touch screen problem is not caused by an app as the touch screen is also not working in the recovery mode (TWRP). Any help will be appreciated.

Screen and touch, display assembly is connected with only one cable on our device(navi buttons and fingerprint scanner are different). So if touch broken, probably it won't be able to repair. They will replace the entire screen.
Seems this thing happen to many people, i got it loosen in the same area as yours
They use double side tape which soften overtime+removing the phone from the case break it
Though my tc is fine because when i notice it i immediately glue it with standard tc glue instead using double side tape (much simpler, without opening the phone)
I recently got my phone and I am frequently experiencing a really annoying issue: while I'm browsing reddit, facebook, etc. the touchscreen appears to be overly sensitive, so whenever I scroll holding my finger on the screen, when I lift my thumb at the end it registers a small scrolling movement making the display jitter/jump slightly. I have the "touch sensitivity" settings turned off and I do use a glass screen protector but that wasn't an issue with my previous 200$ Xiaomi.
Is it a defective unit, or are all S21 FEs like this? Is there a fix expected? Otherwise I will consider returning my phone.
I don't have this issue but, I don't use screen protection and the screen refresh rate is set to 60Hz (and sure, "touch sensitivity" is also set to off)
Did you try with both refresh rates?
What processor version does your S20 FE have?
Mine is the Snapdragon one
It's the Snapdragon version and switching between 60 or 120hz doesn't make a difference
Experiencing the same issue and reported it to samsung via the members app.
I've made a screen recording in 60 fps using scrcpy and the touch debugging enabled while viewing a grid paper PDF.
You can clearly see on many swipes where there is a random 1 or 2 sample points extra when the finger lifts off. It seems to be mostly triggered when trying to do precise movements, like trying to align the grid to the edge.
Hi Team
I can confirm, that I was facing the same issue right after the purchase of the phone. But after the latest update, the issue is finally solved for me ;-)
