U-touch problem - Lenovo Zuk Z2 Pro Questions & Answers

Hi all,
New to this forum. I used my phone during light rain, and thereafter realised that the U-touch button became totally unresponsive to touch (physically pressing it is ok), including swiping, long press, short press and fingerprint sensor.
Anyone facing the same problem or can suggest how I can rectify this? The only thing I've tried is rebooting but it didn't work.
Thanks!

Hi,
I never had any problems with mine.
Did you go into the settings and reset to defaults?

Hi shaunydub, yes I've tried that, and also upgraded firmware but to no avail.

Zuk didn't say it's waterproof.. T-T

But they say: U-Touch 2.0
Innovative Wet Hand Mode
So they want you to touch it with wet fingers

It sounds like the perfect time to flash CM on it.

Bumping because I'm curious if the OP solved this issue and if others have encountered it. Should I be super careful not to use the phone in any kind of rain?

Any update on that problem? I have the same problem. I'm already considering buying a new home button...

[Q] Milestone touch screen problem???

Yesterday when i take my milestone out of my pocket I noticed that the Settings touch button(second from left) wasn't working, every other "bar" button was working fine, except that one. Then I noticed there's a vertical line, that goes from the Setting button to the top of the phone that doesn't work. It simply stopped working... Some1 Help me pliz. It' s a Software or Hardware problem, and if it's a Software problem this thing will solve my problem??

same with my phone, may be digitizer was broken
Are u using a custom Rom or the Original ? My touchscreen had a similar issue, and reflashing the ROM solved it. It took 2 flashes, but the issue is gone.
Dont know if yours is the same, but if the issue still remains, atleast it can confirmed that its a hardware issue and not a software one.

I have used CM6 on my phone, but when i got this issue, i made my phone back to 2.1. The problem is still standing.
uh oh. Looks like a Hardware issue then. U still might wanna take to the store and get it verified. Is it still under warranty ? Any possibility of an exchange ?

This may solve my problem??
Havent seen any such issues.. Thanks god..
it's similar to my problem, I had the back button through the top of the screen not working..
I have tried flashing, factory resets, and whatever I can do, but still no changed,, so I tried to ask the closest customer service and they said that it's the touchscreen panel must be thrown away to get the new one..
is it really true ?
please share this problem,,
thanks,,

Hi all!
I was having the same problem with the column of numbers 3, 6, 9 of dialpad. Looking for the solution in google, I have read that this problem is probably caused due to the moisture... so yesterday I turned of my milestone, removed the battery, SIM and SD cards and left it inside an enviromental chamber @ +70 celsius degress for 1 hour and guess what? Problem solved!
I hope that it works for anyone that are having the same problem!
Regards
Lucas

I have had good success with a combo of rice (inside a ziplock bag) to absorb humidity and/or a toaster over at the lowest bake setting.
Worked on MANY electronic devices over the years.
Sent from my Milestone using XDA Premium App
Same problem here. I've solved it by changing the digitizer (ebay 25 euros). Works fine now but in the mean time I change for a Desire HD... good by Milestone !
If you decide to change the digitizer, be patient, fixing th Milestone is not an user friendly task But if you take your time it's ok !
ive the same problem, and i believe that's because of moisture. because every time when its raining except the problem with right side of screen im not even able to use the phone touch screen doesn't work at all and the phone just does something by itself! this issue started with small vertical bar from right side of screen and it growing everyday now im not able to use right side of screen till home button.
i want to know do i have to replace touchscreen or i can fix it with something to absorb humidity?
thanks in advance

[Q] Applications are looping at their startup and screen flicker now.

Hi all,
All of the sudden, a few of my apps(not all) started looping, especially at their startup.. really bizarre.. Like Angry Birds...it lets me finish a turn then restarts as if i had never played that turn...
Also the screen flickers just a little when going back to the home screen. Never did it before. Like coming out of using an alarm, going back to home screen it flickers at the bottom and top of screen, but not with coming back from home app drawer or camera.. Just some apps again.
Now i did drop it about a week ago roughly 3 feet on hard floor(tile) but it is wearing a protective shell(from holster combo) and seems okay otherwise...
No other symptoms..I am not rooted(Because of that qe 0/0-Is there a hack for that?),Im using APEX launcher.... Thank u in advance.. I did search for this a few times but no results..
I did a recovery,, clear cache, twice. Then twice a factory reset so i am starting fresh and hope that works.. BUT, I would like to know what caused those problems so I can learn..

hey richsapf, no one cares about your dumb apps looping around....LOL,,,,

Probably no one else has had this issue. Is it still doing it after the factory reset? I wonder if there is a some sort of circuit or something causing like a little power surge from the battery.

Hi....
The only thing that helped me was to do a factory reset... Thank you for replying!..
Actually it seems that this issue was due to the verizon microsim, I remove it and my phone works verry well now.

touch problems, starts zooming instead of scrolling

It doesn't matter if I have stockrom or custom (as we speak iHackers stockrom 1.1) the touch drives me crazy.. For an example when I surf on the Web and want to scroll down it works time to time then suddenly when I press my finger on screen it locks on that spot and start zooming page instead.
Exact same problem with the Facebook app.. Some setting? Would really like to disable it. If it's possible.

There's already a thread dedicated to the touch issues if you search a bit. In my opinion it's a hardware issue. I think it has something to do with a short somewhere between the case and screen.
Look here: http://forum.xda-developers.com/showthread.php?p=47791462
There is no need for forum members to start a new thread about the same issue every day. You could have posted your question in any of these 4 threads that discuss the exact same issue.

And to answer your question, it isn't a setting and it isn't related to any specific apps. It's a widspread issue that affects a lot of Z1's and while there are many suspicions, there isn't any confirmation whether it's a hardware or software problem. A Sony rep called Rickard has posted about a fix that is coming in the next software update here but it remains to be seen if that fix actually works.
Right now the best advice we can give you is to take your Z1 to the place you purchased it from and ask them to get it repaired or replace it with a new one under warranty.

Welocome aboard with the Touch Screen Issues. (just kidding, I know its not happy time)
BTW, return your phone to the Store where you bought it to repair or replace via warranty. It's 100% faulty device.

Dude have you seen the latest leak of Sirius in XB? Maybe what the sony rep is saying a fix will come is that they will port the glove mode to the z1

I didn't. Do you have the link? I think they are aware now of this problem and they try to fix it, I hope so, but for the solution we still waiting.
Mine did the same thing, I tried rebooting it and the problem went away for a day or so, so now I use an auto reboot to reboot every morning at 3am. Done this for three weeks now and the problem has vanished.

Maybe on 4.2 you didn't know how to reproduce it but if you want to know my touch screen get worse after upgrade to .290 so you are not the only one.

It's the same. Touch screen do not recognize the movement of the finger but it do like you will just touch it one time, touch screen problem. Had problem even on scrolling pages.

correct, also when long pressing you can see that the screen fails to recognize the touch after a few seconds. really annoying when playing games.

Home & back button stopped working

I'm running SLICK s422 ROW on a 2 1/2 week old K3 Note & suddenly my home & back buttons have stopped working. Strangely the menu button still works fine. I'm having to use on screen software buttons to navigate. Has anyone else here had this problem, or a possible fix? I've seen a few reports on the internet of others with exactly the same fault.
I had the handset shipped to the UK from China, so don't suppose I'll be covered by any kind of warranty.
I've tried rebooting into recovery mode & don't feel any haptic feedback when I press them either, so I don't think it's the ROM.
The buttons have started working again!? I pulled the battery to stick a 2nd sim card in & they sprung to life. I did try pulling the battery out before, without success. I'm not complaining, but it is very strange.
hi I have the same problem since this morning. Only left side button work. But when the screen is locked i can start camera and move padlock on screen so buttons are working. After screen unlock they stop to work. Any solution please. Reset and pulling out battery doesn't work.

Hi, I run in trouble with the same. Only menu button works, I got this phone from China as k50-t3s and played around with k50-t5 and Indian Rom. Is there any solution meanwhile

did you modified a factory t3s and then it stopped working?
So there may be an issue with using different chargers with this phone that causes this problem. I only experience this after I've used one my other chargers to charge the phone
FIX?
Note this is just a temporary fix. Like Sandancer75 mentioned, simply remove the battery from the phone for a few seconds and try again. The response on presses after requires a little more effort but atleast it got the buttons working again
Hi. Im a newb. Is there anyone who kind enough to tell me how to update and root my lenovo k3 note k50 t3s? I tried to read the comments but i got lost. :'D please help me.

Home and back buttons​ not working
Hey fellas, my device started​ showing the same problem. Does anyone know how to fix it? Thanks in advance! Peace
Same problem
Does changing the ROM help?
Hey kdobrev,
Thanks for your reply,
I've tried 3 different roms but no success.
Regards
I've got the same problem, changed the bootlogger, the ROM... you name it but no use. Now I've just replaced a cracked screen and now the navigation keys are working again. I wouldn't advise anyone to change the screen if they haven't some experience - The K3-Note screen is a bit of a bugger to replace.
That's a bummer, but thanks for the reply!:good:

and for those who dont have 'Swipe up on home button active?
i never used that option and still have this random unresponsiveness of the screen. Tried it for half an hour in safe mode and it was fine. But then again, i uninstalled an app and it was fine for a day or so and then it started again.
Welcome to the club, Nokia pathetic quality phones, with low quality screens, headphone jack, usb c port! They said "Build like a tank" LOL.

Have you installed any third party apps form outside the playstore? like lucky patcher or game changer or gfx tools...etc? A hard reset might do the job.

Hi,
no, i do not have apps from other sources. all are downloaded from the play store. I did consider this but dont like it. I'll prepare myself mentally for a hard reset i hate this part because of the backup and data loss and evrything.
Thanks.
i am experiencing the same issue since a couple of months.
i now tried to disable the swipe up on home button gesture, though i really enjoyed this feature. will report back if the issue is gone...
EDIT: issue is still persistent.... any other ideas?
It seems it is a hardware issue, so i don't think it is possible to fix it. Just turn on and off the screen.

i think pressing once and hour 2 times the power button is not so bad... Anyway i understand is not nice at all. I think they will not pay attention at this for you, they don't care much and probably are going to factory restart it and give it to you like it was before. Anyway you don't lose anything trying...

Hmm, I did turn the "Tap to wake screen" on and this seems to have solved it for me. No need to factory reset. :highfive:
I didnt have the nerves to debug this issue and got myself a pixel 3a-XL. There was a promotion and i got it for the price i bought my n7+ back then.
what i will do now is a complete factory reset and see if it solves the issue with the screen. If not, i will mention this as well, besides the damaged charging port, to the warranty service.
I will report back once done. Could be next month tho.
Cheers
I got this problem too, after the october update. Some people at not a forum they have it even since august security patch.
Hmd is a joke same as this phone. This phone should have been rock stable, but is not. There are software and hardware issues that its hard for me to recommend this phone to anyone. Or any nokia phone with android.
