Hello today arrived xiaomi 3s that I bought from gearbest.
It have a problem when it sleeps, I cant unlock It, dont care how many times I press the button It dont do nothing. Even if I use fingerprint sensor It makes the sound of recognotion but nothing appears on the screen.
Dispite this, I can ear notifications and sounds but the screen remain black. Even if someone calls me the phone vibrate and make sound but the screen is black and locked.
Any solution?

Hi everyone,
funny thing happened to my Mozart. Whenever I make a call the screen shuts off like it should, but it doesn't turn on again when i remove it from my ear until the call has ended.
Which works fine if the other person hangs up, but it means I can't hang up. Whenever I reach a voicemail i have to take out the battery to hang up!
First i thought it was a rom issue, i had just gotten my hands on the mango beta when i first noticed it. I thought it might be buggy.
But the problem remains after hard reset and flashing with a different rom (pre-nodo & nodo).
I found out that the sensor still works. The screen is reactivated when i shine a bright light (halogen spot or so) onto it - but only for as long as the source shines onto the sensor, else the screen shuts off again. wierdly enough, direct sunlight doesnt seem to be enough to trigger it anymore.
since i upgraded my phone with a 32GB microSD I guess I'm not eligible for warranty, huh? but im pretty sure it happen long after and i didn't accidently break something while opening the phone.
very weird... any ideas?
I had this problem on the weekend.
I removed the matt screenGUARD, and the problem disapeared.
Also you can reactivate the screen by pressing the on/off button...
thanks for your comments.
unfortunately, I don't use a screen protector and the standby-button doesn't work during a call
I have this problem also, with stock 7392 rom. The sensor seems to work when dialing, but stops a short time after a call is connected.
The power button works for me to turn the screen back on however...
Where is the proximity sensor ?
where on the device is the proximity sensor located?
I have been having difficulty with the screen not switching on during phonecalls and I have to remove battery to end outgoing calls. Pressing the power button doesn't help either. I don't have a screenguard to remove.
The problem started not long after, but not immediately after my daughter dropped the phone down the toilet. It took a few days for the phone to gently dry out and it worked again except for some residual water between the screen and the glass.

The sensor is about 1 cm to the top and right of the htc logo. It's barely visible and it is dark violet. (Or something like that, I am not very good at naming colours.)
Anyway, I sometimes also experience problems with sensitivity with HTC Mozart, mostly during calls, especially when the proximity sensor has been activated. Sometimes the home button freezes after a call... It's a bit annoying.
Does anyone else have this problem? Everytime i pick up a call, my face will inadvertently touch something on the second screen and open another app. it doesn't affect the call, but it's just annoying knowing that when i'm done with the call, my phone will have the camera open or in another app that's in my second screen shortcut. i know the V10 has a sensor up top that turns off the second screen when covered, but it just doesn't seem to work fast enough, because everytime i put the phone to my face, it opens another app.
am i doing something wrong? has anyone else here experienced the same problem?
Same here. I had my signature (name) on it and it always take me to edit signature page. So i have to disable it and i put recent app and app short cut only. And i notice when we are on call they dont show up.
mine turned off during call if i put my phone to my ear. there is proximity sensor which should turn off your both screens when it is closed.
Same here as well, I need to point the phone angle to 45 degrees from my ears to avoid activating that 2nd screen when my ear presses on it. I wish LG would fix this behavior in the next patch
May I know which model you guys have?
because on my H961N everytime i make a call or during call, the second screen turn off.. totally black.. so you won't be able to press anything.

i have the official Hong Kong version, which i believe is F600? i know the phone has a proximity sensor up top BUT, for my phone at least, it only works when the main screen is off (meaning, when the mainscreen is off, covering the sensor would shut off the second screen too). but when the main screen is on, the sensor does nothing, covering it doesn't turn off the second screen, which means the second screen stays on even when my face is pressed against it.
probably nine out of ten times, after i'm done with a phone call, the phone will have opened another app because my face pressed something on the second screen.
i love this phone overall -- it's so well-built; looks great; and the camera is the best in industry -- BUT that second screen is pretty damn useless to me. i almost never use it under day to day use and it actively gets int he way when i'm making a phone call... sigh. i hope the G5 can have V10's build but get rid of the second screen (which would make the phone a bit shorter too)

isn't HK version is H961N as the code? and Taiwan is H962 i believe..
F600 is korean?
I got mine imported from HK and it is H961N
Mine is H961N, which is the model from Hong Kong. This problem does happen when I use the application Line to make a voice call, it doesn't when I use the normal phone application.
Maybe its about the proximity censor couldn't sense our face?
same with my V10, however, it's not a problem.
I bought this 3 phones from gearbest, and the three experienced a common problem, screen goes black, but phone is working, the buttons are on, and you can fell vibration navigating betwen menus.
The mediatek went completely black, no responds, but the other 2 shows the problem once, i restart the phones and the screeen was fine, somebody else experienced this kind of problems? Or maybe this guys sold me refurbirshed phones .
sometimes the indisplay Fingerprint sensor stops working at all.
The display wont recognize any touch and stays black.
If i push the Power button it starts working again.
This happens sporadically, 1 -3x a day
Did anyone had the same Problem?
Any suggestions?
Thanks for reading....
No one?

I haven't seen this problem. I use face unlock along with it and it usually recognizes my face before I can even scan it.
When the screen is black, you can put your finger on the display and some glowing circle Appears. This does not appear to me at all. The screen just stays Black.
Thx for the information.

Maybe your fingerprints got erased somehow? Does your phone display a fingerpring icon on the screen a second after you turn the screen off?
Sent from my LYA-L29 using XDA Labs
Yes the second I turn if off it shows a fingerprint sensor. Just after a while it won't toggle the sensor if I touch the display. It's like the fingerprint sensor is deactivated. The second I turn the display on manually it appears again.
Hello! I've got the p20 pro and now I'm testing mate 20 pro. Sometimes I'm not able to unlock the mate with my fingerprints at all. Same finger. The p20 works perfect, just touch and unlock. Mate sometimes I have to touch it 3-4 times before it unlocks , sometimes it doesn't unlock at all? Is that normal? The display was exchanged already because of this issue.
I believe you guys are not the only one. This on screen finger print is not reliable. I guess because they are new and will improve over time. Personally I just use face recognition than finger print. They are a lot more faster and accurate to unlock.
I know it's an old thread but it's happening to my M20Pro right now! It's awful! The screen is protected by a tempered glass made by Spigen (maybe this glass has issues?). I reconfigured the fingerprint and I touched almost 50 times until the phone captured the fingerprint! What's wrong with that sensor?!
I had problems with glass protector, if you can get plastic film it is fine, glass you will have problems....this was my finding
Possible brightness/proximity sensor issue

If you still have this phone and problem: I have a P30 Pro, and/but the reason I write here is because our phones share the fingerprint technology, and I didn't find anyone mentioning this problem regarding P30 Pro. So:
I have the same problem - seemingly sporadically the fingerprint sensor (or screen) wont react until I press the power button. Then I noticed that when the brightness/proximity sensor (located near the top right on the P30 Pro, and next (right) to the upper speaker on Mate 20 Pro) was covered, the screen would get unresponsive. I guess this is by design, to not accidently let your phone come to life in your pocket. The problem was/is that the proximity (?) sensor is way too sensitive - any obstruction at about 2 cm (0.8") above the sensor(s) will trigger this behaviour. I also think it can be triggered under other circumstances; I had som weird fingerprint/screen behaviour in a store with a high and very dark ceiling, but I have to test this again, so don't take my word for it.
Anyway - if anyone is having sporadic problems - see if this could be a reason.
Edit: Well, sometimes my screen is just totally unresponsive even without sensors blocked, so ... I noticed it a couple of times after digging my phone out of my pocket, suggesting it could still have something to do with the sensors turning the screen (functions) off. I'll try to see if I can make it behave the same way in other scenarios.
I have also been experiencing similar problems on my mate 20 pro, But mine is more of an accuracy problem. sometimes its on point and registers instantly. and other times it just doesnt at all.
However i have noticed that in extremely bright weather i have more issues, fingerprint doesnt read at all, and face ID is also doesn't. My finger print issues have started only after EMUI 10.1, so i suspect that it could possibly be a software related issue
Has anyone else faced with the issue of display not working properly in K20 Pro?
I started facing few problems from day 1, though the problems were minor like
.
[Problem 1] When using the phone with dark mode on or with absolute black background with 0-25% brightness the screen didnt respond well to on screen movements. Like when scrolling, the items on the screen produced a blue shadow on black backgrounds.
I thought this was due to Xiaomi's usage of cheap & low quality Super Amoled displays. Im not sure if it is as i thought it is or due to some other reasons.
[Problem 2] after 25-27 days of usage the ambient disolay started to switch of automatically after a few seconds of locking the screen. And when i tries to unlock the screen by fingerprint, te scanner didnt work. I had to push the lock button and then the screen switched on after 4-5 seconds of pressing the button(i was pressing the button only once and not holding it).
I still dont know why did this happen (I'll update soon)
[Problem 3] after 2-3 days of the problem 2 one fine morning my screen went dark.... Like completely blank, although i tried switching on and off multiple times but the screen didnt show a single hope to turn on.
So i took iit to the service centre and found out that there were many people with the same problem. Most of them being the first launch sale buyers(including me).
SERVICE CRNTRE told me that there was instructions from the comoany(Xiaomi) to collect all the Faulty screen K20 Pro's and provide a new sealed box within 1 week. Providing that there are no signs of external damage to the handset. Peoole will have to suubmit the box and its contents with the phone.
So Yaaay! For that but Naaay! For xiaomi for producing soo many faulty handsets out of the factory.
I'm writing this post as there are no posts regarding this issue on the internet and i was shocked when my phone went dark.
i’m facing problem 1 too
but no touch issue or burning for me
mine is China 6/128gb variant
