Problem with digitizer/touch buttons - Xiaomi Redmi 3 Questions & Answers

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

typical problem with the touch pro...because its a slider you probably need to replace the flex cable from mother board to screen, i had same problem with mine i thought at first it was the digitizer but dont be fooled.
back up the pim file on the computer and see if you can get the phone replaced under warrenty would be my suggestion.
Not sure if you have fixed the problem yet or not but I just recently had this same issue. I replaced the phone under warranty and before I sent it back I installed MyMobiler to navigate the phone and save any files I wanted to keep locally on my PC. Obviously activesync saved all my contacts and whatnot as well.
The sad part was I had only had the phone a month and 2 weeks so they couldn't give me a brand new replacement since it was over the 30 days, so I had to settle for a Re-Man. blah
Oh well good luck mate!
I have the same problem. I just called tech support and had them sent me a new one. Something that may elongate your use before you get it replaced, press down on the screen between the lower buttons and the LCD screen (the Verizon logo). It seems that the more that i do it, the worse it get, but slowly. Here is a video of me making it work.
Good luck!

hm... try hard-reseting the phone. but back up your data first using some backup software like sprite backup
Tried that as well no luck any other suggestion guys
Sent from my HTC HD2 using XDA App
I had the exact same problem, and I had to hard reset everytime, but as soon as I would press the end key it would be unresponsive. What I learned is that right after you hard reset you should only try waking pressing other keys than the end key and let it go to sleep by itself. Also did you use any EVO android builds, or Android at all, not sure if it's relevant, but that's where it all went wrong for me with the EVO build. I do find it quite odd that quite a few people are experiencing the same thing with the touchscreen and it also seems that there really isn't a solution to this. I had to send it in for a repair, and it got fixed pretty quick. Perhaps this needs to be investigated more.
i have same problem with my htc hd2
it is so annoying. i will send to repair service too..
hey i have the same problem too ! did you installed the new c0okies home tab ? because i did and after that it start it messing up.. well i did a thread yesterday about this.. the only responses i got was to send it back to repair. I just did not turn off the screen for nothing today during the whole school day it almost finisihed the whole day, it last it me about 6 hours without turning off the screen, otherwise the touchscreen becomes unresponsive.
Temporary fix/test
I just fixed it temporarily, i fixed it by taking off the battery cover and pressing down on the htc logo (below lcd) and pressure on both the front and back of the phone where the htc logo is.
if you do this and it fixes it, you most likely have a dodgy lcd/digitiser flex ribbon cable.

Buttons broken - Please help

Hi guys,
My Vibrant screen recently broken hence I ordered a new screen from ebay. Got the screen today and while removing the old faulty screen, I accidentally tore a thin wire which was connected to the 4 buttons at the bottom. Out of the 4 buttons, 3 of them just came off the screen. So now I have successfully replaced the faulty screen with the new working screen. Everything works except the 4 buttons at the bottom. I press those buttons but nothing happens, not even the backlight comes up.
I believe I have done some serious damage to the buttons. What's my best options now? Should I take it to Samsung Repair Center? Will they even be able to fix this issue?
Its so frustrating because if I open any app I cant go back. I have to restart the phone to be able to use any other app.
Please help,
Dinesh.

[Q] [HELP] Xperia Mini Pro Broken Screen

Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
