Intermittent touch screen - HTC U11+ Questions & Answers

Hey all, have had the phone since release back late last year. Been perfect so far.
Over the weekend, suddenly in the afternoon, I wake the phone up, and the touchscreen doesnt respond. Held down all three buttons to hard restart before it worked.
Thought it was just a one off, but it happened several times over the next 24 hours. to recover, I have to hard reset, or sometimes even several (as on occassion the touchscreen wouldnt work on the encryption page). However, when it works, it would work perfectly for hours on end.
Have reset the phone. same.
ideas?

[Q] Screen not responding to touch

Hi everyone, just got the tablet today and set it up at work, played with it for bit and everthing was working fine.
Got home about 2 hours ago and now when I wake it from Sleep, the touch screen is not responding at all. Have tried everything, power is 98%, plugged into a PC, did the hard reboot, even wiping the data to start setup again. But all to no avail.
The screen isn't responding at all. Its very frustrating as I want to play with it some more!!!
Hope someone has experienced this and can help.
had the same issue once...i turned it off and left it for about 5min...turned it on and the screen works again...
this hasn't occured since then..probably just a system glitch..
Happened to me once, reset the device and it worked. Now it happened again and its been unusable for a day. If it doesn't work tonight, the $hit is going to hit the fan...
Are you stuck at the lock screen immediately after booting because the unlock function doesn't respond to touch? If so, I'm having the same situation. I really hope that waiting a few minutes does the trick...
Edit: even did a full wipe and the thing is still unresponsive. I assume this is a very bad sign. FML.
Have you guys contacted ASUS support? They will probably have you RMA it. How long did you guys have it before this happened? Now I'm worried that mine will do the same thing.
ASUS support did want to RMA my TF that was having this problem. However, after leaving it off for a couple hours, I went to turn it on to wipe out all my account settings and the touchscreen started working again.
I have no explanation for why it started working though. The last thing I did before it was magically fixed was go through the normal shutdown procedure by answering the 'do you want to shut down' using the dock's mouse instead of just holding down the power button. Maybe that made a difference?

This is what happened to me. Stuck at the lock screen, no touch at all. After 4 days of waiting for Asus to reply to my email and several disconnected phone calls, I have returned it to newegg. Since this item is still out of stock I expect to receive a full refund. Which is fine by me. June 8th, here I come.
Same thing happened to me, just returned it to fry's and was able to avoid the restocking fee. Going to get the galaxy tab come june 8th now instead.

I have weird little quirky things like this happen from time to time with my TF, such as having to hit the power button or lock button twice before it works. I think it might be more of a software issue than anything to be honest. Hoping that future updates will correct all of these issues.
I hope its a software issue....
Found a solution that worked for me. I booted into recovery mode by holding vol down and power. then I selected vol up to enter recovery. Then the exclamation point came up with the android robot. I left it like that for a few minutes then held down the power until it resarted.
It booted up like normal, no data lost. I then restarted for good measure. Came right back up like normal, touch screen and all.
Thanks jdmnash. I followed your instructions and it worked like a breeze. Should make this part of a sticky help thread.
Found a solution
Update: Tried every fix I could identify on the forums as I was also draining the battery as suggested on several forums. After 4 days waiting for the battery to drain, I was able to restart the TF and get active responses to the touchscreen. Unfortunately I had performed a reset and wipe earlier so I am having to reload everything. I am happy to have a functioning TF again, but have serious concerns about this failure and this awkward repair method. Additionally, I have still not had a response from ASUS support from 5 days ago.
Mine is constantly doing this. Randomly.
Its as if the daemon for screen touch detection crashes. The rest of the unit is fine but that stops and the only fix is a power button off, then on.
Something is not right here. Its vanilla out of the box, no extra software just the 13 FW update.
Will 3.1 fix this? Hopefully, as it stands, this will have to be returned. It is not fit for purpose, constantly failing.
same problem
Just picked up mine. Out of the box at a cafe it worked just fine. Brought it home and same problem as everyone else in this thread. Have tried all of the suggestions in this thread (except waiting for the battery to die). Even installed the 3.1 update via SD. Still no joy. Guess I'll try a few more things before returning it. My guess is a problem in the supply chain with the capacitors that detect screen touch. Doubt that it can be solved solely through a software update (or if it can it definitely didn't make it into 3.1)
my touch screen stopped working a week ago while i was at school. and i got really pissed and just kept on rebooting it and after like 5 or 6 reboots it started working. Havent had same problem since.
Hmm... thanks for suggestion. Tried booting it about 5 times but still borked. Draining the battery now as my last attempt before taking it back.
Update: I ran the battery down to zero. Charged it up for 30 mins and now it works again. Hope I don't have to repeat that very often.
BTW, the fastest way I could find to run down the battery was to power on while holding down the volume down button. Then just leave it sitting in that state until it reboots itself and then repeat.

Hi , After the battery is zero and then 30 minutes charging, in order to make it work , did you discharge it right after 30 minutes or still you keep it charging ?
I got same problem with my TF which is really a disappointment.. I tried to factory reset, reboot ... but still can't make it work. I have to try this trick by draining the battery to zero. Hopefully, I get advise from all of you for this problem ?
Thanks a lot
Can you guys try using ADW launcher and see if things improve?
I think it did for me.

Is it completely bricked? What should I do?

So I bought this Huawei Mate 8 and to be honest I really loved it, it's the best phone atm imo. And it's pretty expensive in my currency. I've owned the phone for a couple of months now, 4 months I'd say. And just 12 hours ago, problems started.
It all started when I attempted to use the fingerprint scanner and my phone randomly restarted. Huh, I ignored it. But it happened again when I tried to open settings. It'd crash randomly on random actions. But it almost always crashed when I tried to open settings or use scanner. I removed my SD card and then it worked fine for a couple of hours, then it restarted again.
And sometimes it restarted many times over to the point where I'd think it's boot looping. But it'd eventually start. I reset the phone hoping it'd fix the problem if it's software related. But it always restarted right before I could enter my Google account to start the phone. But it reached it's eventual death. It crashed again but it didn't restart this time. I tried connecting it to its charger, but no response and no heat at all, not even in the charger's adapter. And my laptop didn't detect it at all.
What should I do now? This phone is new and expensive. I'm very careful with my devices and it's in a perfect condition. The only incident with it was when my selfie stick got too tight on the power button for like 10 seconds then I took it out. That was the same day the issue happened, so I'm not sure if it's just a coincidence. Anyways please tell me what I should do right now, and yes, the phone is still in warranty but I doubt they'd change it for me, their customer service is **** where I live.
Update
A couple of hours later, it was completely and utterly dead. I tried to press the power button and it turned on, it froze on the Huawei logo for like 3 minutes then it restarted again. It's acting really random right now, random restarts and then completely dead, then alive again...
Update #2:
I hard reset again and it's working pretty fine for now, I'll update again soon, but I strongly doubt that the problem is gone.

Unresponsive Touchscreen

I dropped my HTC 10 in the water about 2 weeks ago. It didn't work anymore so I put it in rice for 3 days and all seemed fine, only some small damage to the display.
Starting about 4 days ago the touchscreen randomly stopped working. I rebooted and it worked again, but every time I disconnected the charger from the phone after overnight charging I would have to reboot it because the touchscreen wouldn't work.
Rebooting after overnight charging isn't that big of a deal so I just went with it, but the unresponsive touchscreen started occurring more often, and now the touchscreen stops responding within two hours from the latest reboot.
Description:
It's not always the whole touchscreen, sometimes it's only the back and the menu button which stop working. The buttons never work without the rest of the touchscreen working though.
Sometimes a reboot doesn't work and I have to reboot it until it works.
The touchscreen always becomes unresponsive from a locked state. So if I were to never lock my phone I wouldn't have any trouble with the touchscreen.
Because a reboot usually fixes the problem and it only occurs from lock I figured that a hard reset might fix the problem, but I figured I'd ask here first.

Constantly rebooting

For about 5 months my phone will randomly restart. It doesn't seem to have any rhyme or reason as to what app I'm using when it does it. It started just once in a while, then a few times a week, to every day and then multiple times a day. About 3 months ago I cleared the cache as my first "fix." Didn't work. About 1.5 months ago, I hard reset my phone, but restored my settings. I thought that worked, but less than a week later, the rebooting started again. So then last Thurs, I hard reset and did NOT restore any settings and basically set my phone up from scratch. the next day, my phone reboot, and every day since and today when I woke up my phone on the charger was off and wouldn't turn on (with 100% battery on the screen) until I essentially "soft reset" it. It has since rebooted 2 more times today.
I have a lot of apps on my phone, many that aren't used regularly. Booting into safe mode is the last suggestion ATT had but how in the hell do I figure out what is causing the problem??? Also, has anyone else had this issue and waht was the reason and solution?

BlackScreen

Hey everyone,
my phone worked perfectly until couple weeks ago the new MIUI 9 patch came out and downloaded it. It was all fine for first but when the phone eventually restarted and tried to load in for 1st time it didnt want to do it. I've waited for an hour and still nothing happened so I decided to reboot it with volume and power buttons, after that it turned on and worked perfectly. Last Saturday I was using my phone when it suddenly froze and had to reboot it, for about a hour it worked and after that it turned off and ever since than I can turn it on at all. I've tried everything reboot, factory reset everything but the screen doesnt respond to anything at all. Only thing what I know is that when I plugged it on my PC, it respond on the connection but still no answer on screen. I'm asking your help since I can't use my phone for a week and noone else has an idead in my friends what could be the problem.
