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 .
Hi guys,
I have a Redmi Note 4 Snapdragon with a screen replaced recently. The problem is the screen only works after the phone is booted, if I let the screen turn off, it can't be waken up again. There's still backlight, vibration and all and I still hear sound. Which means the touch does work, only the screen doesn't display anything, just black. What can be the cause of this? Thanks everyone!
I have exactly the same problem on a Redmi Note 2. And this problem is not so rare because i found a few posts with same symptoms but i cannot find a fix. If you please find, please let me know.
Can I ask you something cause I'm a technician and I face similar problem not exactly the same. Were your screens bought with frame already glued and you face that issue? Usually such issues occur when they is no duct tape (sorry for my English) at the lcd flex cable where it folds under the frame or where the backlight circuit (I don't know the correct explanation in English I hope you understand). So I needed at my phone to replace the frame as well that's why I bought a lcd with frame (that of course was terribly glued). My issue is blacklight flickering when it wakes from sleep and if I push the edges it's ok. I have replaced a lot of note 3 LCDs without frame and I know that in all of them I had to put duct tape to make them work properly and without issues, I had only one for note 3 pro SE that was properly made. So I believe both your issues as well as mine have to do with that. If you have the broken ones, take apart the new and check side by side the flex cables and if you find exposed connections compared to the original just put duct tape.

Perhaps you might want to enlighten us as to which ROM are you using, and who is the manufacturer of the lcd display?

Hi, I'm using the Ressurection Remix ROM on Android 7.1.2, planning to update to Oreo soon with the Pixel Experience ROM. And the LCD manufacturer is Tralfagar.

Well, I don't know about Trafalgar - but if the new display is has an ebbg chipset, then you may have problems. There have been issues with ebbg displays and TWRP (when using custom ROMs - see for example https://forum.xda-developers.com/re...redmi-note-t3716706/post74815338#post74815338). Does everything work properly when you reboot to TWRP recovery? If not, then this may be the problem - and you may need to change your ROM to the latest MIUI releases.
I am facing same problem
I have redmi note5/5+, using custom rom (ion), I am facing same problem, changed lcd two time, tried with other roms, but nothing improved, did you find any solution.
Hello, last week I had to replace my phone's digitizer. I bought one that included its frame to make sure I don't break the flex cable, I hooked up everything and I'm sure as hell there's nothing wrong. Randomly when Im going to unlock the screen doesn't respond, also noticed that when it happens the menu button is always "pressed" even if you don't touch the display, is there a way to fix it, my brother has a redmi 3 too and after he replaced screen same things happen. He has lineage OS and he can reboot because screen doesn' turn unresponsive
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
1st batch
I just bought a new Redmi note 8 pro 7 days ago
Right now I am having an issue with my proximity sensor
Its not working properly..
Whenever I call someone my screen turns black.. No. Matter whatever i do it stays black...
Then i have to force restart my phone to cut the call..
Kindly help regarding this issue..
Tried each and every thing, changed glass protector, cleaning and tried different apps.. I did everything I could do..
I'll be grateful if anyone solves my issue..
Same issue here. Did you find a solution? Thanks.
I think some issues are there in the new updates itself.. i am also using the redmi note 8 pro and my proximity sensor also has some problem, however i don't have to force restart my phone. The thing with my phone is.. my proximity sensor does not work properly.... i believe the screen should be off when i am talking in the phone with the phone on my ear.
