Mediapad M3 touchscreen turning almost irresponsive or numb all of a sudden - Huawei Mediapad M3 Questions & Answers

hi folks,
that's one very annoying behavior I run into from time to time: all of a sudden the touchscreen has quite a lag responding my gestures, I have to insist or even press hard to make it "understand"... it generally gets only one touch event on the middle of a swipe (e.g. if I want to roll through apps screens, it does not swap screens but instead runs one of the apps that's on the swipe path - grrr). The keyboard turns practically unusable. Even the SIM unlock code entering after boot gets hindered by this ... very very nasty, really have to resist not to smash the freaking thing against a wall... (you get the idea how frustrating that behavior is)
Note the fingerprint sensor is impacted too . It looks like the whole front panel touch management gets crippled by some background task or I don't know what...
I have no idea how it happens, generally the tablet is just idle w/screen off and the darn behavior fires when I wake it up. Reboot does not fix it.
It's unclear how it disappears as well ... I have a feeling that sometimes turning to sleep mode (screen off) and waking up again fixes it. Not sure because it's only the second times it happens in about 2 weeks time.
Any shared experience, any idea, welcome...

Hi! I have the same problem, sometimes my tablet doesn´t detect my fingers. I try installing Touchtest app and then realize that It happens randomly. I requested a replacement but the new model have the same problem. Maybe is a software issue.
PD: Sorry for my english

Sense Keeps Crashing

im wondering if its just me..
most times, when the phone comes out of sleep, after i slide to unlock, it just hangs. i dont even get to see the clock, sometimes, it just shows a black screen, and sometimes, all i see is the lock screen..stuck.
i can push the start button, and it would work as normal, but i cant go home.. and everything else related to sense...music, settings, message, ..just crashes.
i always have to reboot phone to get it back to normal.
could there be something making it crash? ..and does it happen to anyone else?
yes it happens to me from time to time. sometime HD2 just lies on my desk and 'fall asleep'... cannot turn on the screen though all the buttons light up.
when this happens i have to call from my HD to turn HD2 on and when it's on, it's unstable, and i have to reboot it.
same problem
I have exactly the same problem. it just crashes for no reason. sometimes when WiFi is on. sometimes after I synchronize. sometimes if only plugged out of the charger.
it was in version 1.48 and kept happening even after I upgraded to 1.66
I hope this has a fix or something or atleast a way to restart sense because the Windows button works, phone works, except the volume, the turn off and the settings in the start menu..
help!
thank you in advance.
Same problem here. Freezes at the lock screen and the lights appear from the buttons. Occurring with worrying frequency now. Twice in the last three days. Any ideas?
folks, do report your issues here .. i have a feeling that this is a known hardware issue by HTC and they are just keeping veru quiet about this.

Same thing here, it use to happen 2 time in 2 months since new, but ever since i upgrade to 166 is happening everyday
I am really really disappointed with HTC HD2 he came out with some many bugs that i am after 2 months of hade and love affair really considering divorcing ones for all.
Nice looking screen but no reliable atall enough is enough

[TEST] touch screen/calibration issues... may have figured some things out?

Ok, so over the course of time I have owned my phone I think I may have found one of the reasons for the phone to go out of calibration in terms of touch accuracy but I just want to make sure its not just my phone doing it.
What I have noticed is that if I hold my phone at an awkward angle for a few minutes (typically 5ish minutes) the calibration will go out of whack. This notoriously happens when I have my phone in navigation mode and just laying on my lap (landscape mode). Today I was driving and I got a text mid way to where I was going so I picked the phone up to hit the talk-to-text button (which is really nice for texting while driving by the way) and it was out of calibration, could not hit the button to save my life. Similar has happened when I held the phone at an awkward angle while watching a movie laying in bed. So I would like to see if anyone gets similar results holding the phone at an awkward angle for a few minutes, I would say give it 5-10 minutes for an accurate result. Try doing things like holding it literally upside down while its in landscape mode and then switching it back to portrait and type on the small keyboard again. I would go into a program of some sort that you can test touching all areas of the screen with.
Now, it seems like before the OTA update, I would have to reset the phone and sometimes that wouldnt work still. However now (and I have tested multiple times with consistent results) that if you lock the phone and then unlock it, the calibration seems to be adjusted again.
Let me know your results.
**For the record, I have had a very positive experience with this phone since I purchased it but I have been able to replicate the "touch screen issue" many a times and would just like to get to the bottom of the issue if all else to just avoid it or tell others how to avoid it happening to them because it is quite annoying.
it sounds like a software hiccup i would hope it would be getting patched sometime..... but as of now i dont know of anyone that's got a fix for it. i have the problem from time to time but i just lock and unlock and its fine, kind of annoying but not something that makes me want to throw it out the window or anything.
Judging from the behavior, I'll place my bets on it being a software issue rather than hardware. There seems to be some hiccups between the accelerometer and the screen getting confused about angles/tilting.
didnt happen to me before upgrade. Its happened a couple of times since.
My phone had been on charge and I had changed to setting to disable it from sleeping while on charge. I had turned the screen off but it must have woke up I went to use it and couldnt hit any keys.
I thought it may be something to do with it being awake for a long time - but it could be coincidence.
I can confirm that putting the phone to sleep and waking it fixes the problem
I have the same issue. No problem before OTA and described problem after that. Grrr.
Mmm, I experienced the problem both before and after the OTA, so I dunno.
Good to know that you can just sleep the phone and then wake it back up to fix the issue now. You used to have to reboot.
I have not had the issue at all since removing live wallpapers. Maybe just a coincidence.
Do people using custom ROMS have these issues?
Ok, so there are similar results out there then and sounds like 100% confirmed just locking and relocking recalibrates the phone back into proper order, no more full reboot is needed.
For the record, I am not using a live wall paper, I have not rooted or installed any themes or anything so my phone is all stock besides the OTA update. Also, as someone else stated that you used to have to restart your phone before the update and I experienced the same thing but again now I only have to lock and unlock the phone for it to recalibrate.
Grainysand you and I seem to have had similar "issues" if you even want to call them that with before and after the OTA and I share your view that there is an issue between the accelerometer and the software recognition.
It's definitely the accelerometer. For the record, I've never had to either reboot or relock/unlock the screen to fix this. I hold the phone upright and it corrects itself, though sometimes it recurs.
I've noticed this a few times after the ota, but just turned it off/on to fix.

Same here. Usually when in landscape mode and the device is tipped at a 45 degree angle. I've also seen the N1 (when using the browser in landscape) scroll the page back and forth very quickly (about 1/4"). When this happen the device seems to get 'stuck' in landscape mode even when I flip it back to portrait.
After the ERE27 update, I've only really noticed the issue when I've plugged in the charger.

now that I think about it, I must say that most of the time I see this happening it has been on the charger... will test later though, i doubt this would effect the issue
I think it has something to do with live wallpapers, the ones that receive input touch to react in some way or another. Its a software issue.
You could put it to sleep and on wake up its ok.
Or you could touch the buttons slightly to the right.

no its not the live wall papers... I have tested both with and without live wall papers and I can produce identical results as far as loss of calibration
Not sure if its the same problem but when playing games sometimes, the isnput locks up sometimes when in landscape mode. However rotating the phone between landscape & portrait mode seems to fix the problem, might help for this too.

Screen goes black & everything disabled for 60seconds.

Once in a while my screen will go completely BLACK outta nowhere... NOTHING I do brings screen back on or does ANYTHING at all UNTIL about 30-60 seconds it suddenly comes back on..
**Here is the curious part.. When screen comes back it is ALWAYS in CAMERA mode! weird right? I'm thinking maybe a virus though have found none...
My ONLY other guess is that it may be related to app LASTPASS as im running it at time AND it has a screenlock function after idle timer...
The part with camera showing up on return is quite disturbing though, although maybe thats a result of me pressing every button possible during blackout??
Any clues or similar experiences? It used to occur daily.. Now just once a week.. Every virus spyware scan came clean.. Tho since phone is NOT rooted im skeptical how accurate these virus/trojan screeners can be without system access?
Phone has never been out of my possession & utilize screenlock since day 1...

Weird screen jitter/touch ..phone going crazy

It's an inherent issue with some displays present on the Moto G4. It most often happens when you charge your phone. Too much current builds into the frame of the display and you get weird ghost and jitter touches.
No way around it unless you send it in, and even then it may be only a temporary fix.
I also face this issue. Unable to find solid solution for this. Finally i decied to go for custom rom like RR and Invicta. This still comes occasionally(when Heats too much during phone charging)

On my phone this happens while not charging. Seems to happen about one out of every 3 times the phone is unlocked using the fingerprint sensor. Locking the screen and unlocking via a pin seems to be a reliable way of getting past the issue. Though occasionally it happens on the pin entry screen before it the pin has been entered. Needless to say, it IS annoying.
Same problem which is fixed.
I had this problem with the factory firmware too, intermittent bouts of the phone going crazy with phantom touches on my Moto G4. I sent it to Motorola/Lenovo after the supplier gave me their phone number and they did find the problem and fix it. Now I can play graphic intensive games even during fast charge and the phone is awesome for once. : )
Please note they will fix it for free if in warranty and bootloader not yet modified.
Pressing power button to turn off the display and then pressing power button again to turn the display back on will provide temporary relief from jittery screen. I noticed that the jittery screen has twice subsided over time but came back twice immediately after OS upgrade so blaming the problem on charging, or hardware doesn't seem accurate.
Updated 5/20/2018
As a last ditch effort prior to buying a replacement phone I deleted all apps I installed, reset phone and reinstalled fresh copies of most if the apps I needed.
I don't recall every thing I did but my focus was to delete everything I could and then reset phone back to factory state. After reinstalling, my jittery problem went away and has not returned. Your millage may very, so no promises. Phil

phone going crazy
Hi,
I am having the same exact problem. I have observed that Google Assistant is intruding because each time this happens, Google Assistant is trying to run. Reboot is a temporary fix but the problem persists. I have removed most of the third party apps just to see if anything changes but it did not work.
This is not something that was happening from the start. I have the phone for about 2 months put the problem only started a couple weeks ago. I would love to hear if there is a solution and what. Thanks
Sadly, but compared to the issues visible indoors, in outdoors this Lenovo gift turns complete crap:
youtu.be/dTcHclVEfCg
"Lenovo Moto Z2 Force touchscreen gets completely unusable when getting outdoors! The video is made at about 0 degrees Celsius. So it takes about 30 sec from getting MotoZ2 Frc to sleep with pwr btn (and wakeing up back) to see the touchscreen goes crazy. At -10C, it takes ~5 sec. At +15-20C, after several min it becomes unresponsive and have to use pwr button to recover.
Lenovo, what you have done to Motorola ?!!"
Can it be fixed somehow with changing the upper protective part? I have seen comments that the touchscreen can stop working completely, if peel off the cover part..

Ghost touch issue

It seems my phone has a problem of ghost touch. The status bar slides down automatically and randomly. I turned on developer mode to see what happened, it seems, some coordinates near (320, 0) are clicked very often with no reason at all. It annoys me a lot since it interrupts my normal operation. Did someone has the same problem? And how do you solve it? Thanks
I had the same issue. top right of my screen would think it was being touch when it wasnt.
Yes, my wife's ph-1 has this issue. the ghost touches liked a bunch of Instagram posts, it was hilarious seeing my wife's reaction to this, and then she had to go back and unlike a bunch of crap posts.
But this is an issue and very serious one. I believe this could be also causing battery drain if it interacts with OS and causes deep sleep not to kick in when it should. If the issue happens again I will be contacting support to get this BS sorted out.
I have this issue on the oreo beta although it will keep touching the same spot continuously for about a minute or so and if it happens while the phones locked i cant do anything till it stops luckily its been happening less and less often
I had this happen on one phone but not the others, worse when the phone got hot
i think it's the screen, if you look closely, its not flat. Mine is kinda wavey at the edges, like there's a little too much adhesive, and i think that waviness gets worse when the phone gets hot, and causes the phantom touch

It was gone for 3 days and now the problem is back today. I tried to restart in safe mode and problem is still there so it is a system issue, not caused by third party app.
Same issue here. No rhyme or reason I can see as to why
Mine was happening on my old PH-1 without the earpiece screen, but i got the new version i got has no issue.
This issue is very annoying I'm thinking of returning the device to Sprint and getting another but since it happens so random I wouldn't even be able to show them the issue. Thought it was an issue with the oreo beta but after going back to stock I still have the issue starting to regret buying this phone
I've never experienced this issue on mine
Bump. Been happening to me on Oreo beta. About once or twice a day it happens. I just lock and unlock the phone and it stops. It's weird. I think it has something to do with the screen sensitivity. It's more prone to happening when the device screen is all smudgy or if I just washed my hands.
I have the same issue too.
https://www.youtube.com/watch?v=wbHtJLQEU7o
Me too
Same issue here as well. I did the touch sensitivity trick as well and still getting it. Hope its a software issue and not a hardware one.
I haven't encountered ghost touch but encountered slow responding touch issue. Sometimes the touchscreen will respond to my command slower like 3-4 secs after i touch the screen. Every time this issue appears, a restart of my phone will clear it. Very likely software issue. I'm still on nougat, hopefully they fix it on Oreo before it goes out of beta.
My first PH-1 would become touch unresponsive for 30+ seconds all the time (it was fully updated at the time). It seemed to happen more frequently when I was typing on the stock keyboard. I eventually returned it and bought another several weeks later. I've had no issues with the new one-quite happy with it. I'm running the Beta2 update and enjoying it.

That's good to know. Mine also happened when using the keyboard occasionally as well. I have a replacement set coming as my original set's packaging did not come with the pull tab on the box and there was a fingerprint smudge at the back of the phone when i took the phone out of the box the first time. I presumed mine was a used/returned set, not new as what i had ordered. Hope the new set fixes the issue.
My phone has the same issue whenever I'm charging it and using it at the same time it's registering multiple touches when I'm using just one finger on the screen, it mostly happen when I'm doing a long press action. In developers option I have show taps enable so I'm able to see all ghost touches.
I fixed my ghost touch issue with a simple hard reset.
It will come back sadly
