Touch not working - double tap to wake does - Xiaomi Mi 6 Questions & Answers

Does anybody know what could be the problem? Mi Mi6 was working fine till one day it fall on the back side from my pocket(it has a leather case - scratch marks).

I tried by squezing the touch and suddenly it worked again till today. I have tried everything but nothing works. Any suggestion?No water dmg etc.

Sounds like the touch sensor had separated from the LCD....
Honestly a permanent fix would be to replace the whole screen panel.
A temporary fix would still almost certainly ruin the screen and that would be to disassemble the whole phone and then try and repair the panel that's broken.
I'm not a hardware expert and I've never done more than battery replacements on phones so I can't say more.
Someone might give you a better idea here but I would personally have it repaired by Xiaomi with an official display replacement because that way you get an official replacement.
Such a shame for the drop
Jerry Rig everything does a tear down on YouTube of the Mi 6 so you should check that out for a basic idea of disassembly and repairs etc.
There's lots of good guides

Thx. Ordered new lcd and now works.

Touch Screeen DEAD !!!

There is no touch screen input. The phone works fine but no touch input.
I did a hard reset. Nothing. Any ideas ?
Im thinking there might be something wrong with the screen itself. Maybe if I take the phone apart and put it back together I can see whats wrong with it.
Same thing happened to my Tilt 2 (stock ROM). I tried a soft reset, hard reset, and then reflashing the stock ROM again. Nothing worked, so AT&T warranty exchanged it.
I believe is a hardware problem... Maybe your Rhodium got wet or something like that... You shoul go to your carrier and ask them if the warranty cover that...
actually i had the same problem---BUT
I did fix the problem myself...when it first lost its touchscreen capability, i accidentally pushed up on the bottom of the touchscreen (bottom of the phone) for a brief moment and touched the screen while pushing on the bottom ---AND IT WORKED...but as soon as i stopped pushing up on the bottom of the phone...the touchscreen stopped working......so I simply took apart my phone till I reached the lcd/touchscreen---I even disconnected all the ribbon cables ... (I could not figure out what the problem was because I had originally thought a ribbon cable that goes to the touchscreen had been loose-but all the ribbon cables seemed intact while I took the phone apart)----so I decided just to put the phone back together - carefully AND as soon as I put the phone back together, I turned it on IT WORKED! No problems since...
I really did not want to send the phone back to att because the phone that they sent me was actually 1 phone out of 2...yes thats right I received 2 phones whenever I ordered my phone...they have been doing this for years now...so I dont feel bad
good luck if you decide to open ur phone apart - it was rough...and time consuming ... but if you have a little patience - u should be good
Thats good you were able to fix it..... the same thing happened to me with a htc fuze from att. they refused to warranty exchange it for me though and i had it for less then 3 months.....

need help - touchscreen fix

noticed that my touchscreen is becoming unresponsive lately so i thought that changing the multitouch might solve it. the thing is, after selecting 4 touch, touchscreen becomes totally unresponsive. i tried wipe and even flashing stock os but touchscreen is still the same.
did i screw up my touch screen? how will i know? any known repairs or fix.
thanks
Sounds like your digitalizer (the glass above the screen) is busted and needs replacement. If your phone is under warranty, claim it, if not - get a new digitalizer and if you can't change it yourself, take it to a repair shop.
Changed the digitizer but still no response
Got a headache? It's all in your head!!!
switch ROM
You said that you flashed back to stock, but how about flashing to another ROM, I mean one that has a completly diferent multitouch enabler... that might work.

i was able to flash stock and it means i have no root nor recovery. and adb debugging is not enabled. i am out of ideas how i will be able to solve this.
After flashing stock ROM do you face the same issue with a new Digitizer?
yes. doesnt respond to anything except volume and power. even the 4 touch buttons doesn't work. i was thinking that i have received a bad digitizer or it is a motherboard issue. with the latter i have no idea how to check

I had recently taken my Defy to a service center. I just wanted to change the earpiece and the side casing. While replacing the side casing (while removing the Digitizer) they damaged the digitizer. The main touch portion was working but the 4 soft keys were not. They replaced the digitizer and everything was fine again (had to pay for it )
If you can carefully handle the phone, you can open up the casing and try reconnecting the digitizer to the board. (Do not remove the digitizer from the casing only reconnect the cable).
Replacement is better done by a service center as it requires careful handing.
I did open the phone, removed and reconnected the cable, still the same. also tried 2 new digitizer still the same result. I guess it us the mother board . Any ideas where to get replacement board ?
Thanks

i have got the same problem like you and i have solved it.
Do compass calibration like spin the phone 3 times in flat condition (laying down face up), then have the phone standing up and rotate 3 times, then on one side, rotate 3 times and then move your defy in the shape of number "8" in the air. Re-open the screen. it is suppose to bring back your screen work like it was nothing happened.
only for my defy i've tried never did this for another but from what i see you have nothing to lose here
Tried the calibrating thing and also a new digitizer. doesn't work. So it is the motherboard.
Anyone knows where to get mother board
Got a headache? It's all in your head!!!
Getting a new board is like getting a new phone - new IMEI, price for the board should be very similar to the pricw for a new phone too. If you think about it, it IS the phone. What's there in the phone other than the board a screen and a digitizer...
Guess you're right.

Replacing the screen

I have broken screen on my htc desire hd, i have replaced the LCD+digitizer before. i know my way around this phone.
Is it easy to replace just glass screen ?
I cant see how i can seprate them. they are glued in this black glue thingy.
Better buy whole LCD + digitizer?
by.......................g0tmi1k
I need to do the same. Also since dropping the phone my Bluetooth turns on and off but doesn't always connect. (highlights or ticks option , but I'm not getting anything on the top bar). I disconnect and re-connect a few times to get it working
While I have the phone apart is there anything I can do to fix it?
Sent from my Samsung Galaxy S III using Android Revolution HD
I just replaced the glass only on mine. Unfortunately, the touch screen isn't responding. Anyone know where I might have gone wrong??? Everything else seems to work fine!
Probably a Ribbon Cable.

Try taking it back apart and re-place the ribbon cables back in there seat, they may not be making proper contact. If you replaced the glass without taking it apart you probably un-seated one of the cables. When working on iPhones there is a cable that is only held in place once you close it and put the phone back together.... It's a PITA.
Buy new part and dont replace . Your self its difficult. And its not easy
You can buy a "used" DHD device to replace yours. It'll be cheaper and easier... With a backup on sdcard, your device will be the same !

HTC 10 Half of Display Not Working After Screen Replacement

The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.
Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance
Exactly the same issue this guy has
https://youtu.be/RpdCuMiTOn8
I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory
I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?
I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.

Question Front touch screen on my Fold 3 not working?

Hello, two days ago I notice that occasionally my front screen touch screen stopped working. It starts to work for a while but then stopped for good. I restart the phone and start to work again for a few hours and now stopped again. I hard reset it but no luck. The screen works, but the touch function is not available. I have had it for almost 9 months and it was perfect till this moment. I have the August update from Samsung and I think this causes the problem-software problem maybe?

Try running diagnostics in settings->device care to test it
I can only do diagnostic when the phone is open. There is no problem with the touch screen there,but when I close it the touch screen does not work
Not trying to scare you, but exactly the same happened to me like 2 weeks ago. Screen was still showing everything crystal clear, but touch functionality was not given anymore.
Went to Samsung Repair Shop (Germany) and they told me would need to drop it off there for repair. They ordered front screen, in the end repair person found out that some electric-mechanical components had to be fixed. In addition to front screen they even replaced the inner screen and both batteries!
Fortunately everything within warranty, otherwise would have cost me more than 700€.
Best thing would be, go to Repair Shop near you and let them check the device. Crossed fingers that it maybe is not as bad as with my Fold 3.

Thank you for your answer. I spoke with my friend who has a repair shop and we thinks that the front screen is bad. Lucky that I have 12 months warranty left. Tomorrow I'm sending it back on warranty and to see what the retailer will tell
Hi there,
I had already faced this problem, then I sent my in Fold 3 service center.
