Problem - touchscreen not working properly sometimes - Ascend Mate 7 Q&A, Help & Troubleshooting

Hi all,
I have this annoying problem that occurs ones a day or twice and I have to restart the phone because of it.
Sometimes for no reason in different apps when I type or even use the touchscreen I have this annoying bug that the phone presses the screen few times when I press it just ones, for example when I try to type something it presses the letter 5 times instead of ones and its practically unusable untill I restart the phone.
Any one had this problem before? Any ideas if there is a way to fix it?
I am using the stock is, with Google launcher on top bu this happened even before I used the Google launcher. All stock here and I am using the 16gb eu variant of the phone
Thanks in advance for any help and suggestions

Have you try it factory reset?

No, nothing like that yet to be honest

Seems my huawei ascend mate is having same issue, Have you managed to solve the issue. Share so that I also can try..?

I don't have this problem with my HAM7, though I did previously experience it with an old Sony Xperia. Like you mentioned a reboot temporarily fixed the issue but I had to ultimately do a factory reset to rid the phone of this annoying bug.
Quick question: are you using the original charger that came with the phone? That was another thing that I noticed with my Sony. Its stock charger had died and I replaced it with a cheap third-party one found in the Chinatown of my city. This seemed to trigger this bug, and also caused screen taps to register way off compared to where I physically tapped the screen. This continued until after the factory reset, but still happened when the phone was on charge.
TLDR: Do a factory reset. If that doesn't help it'll probably be a hardware issue.
Hope this helps otherwise good luck!

Ok , listen
when this happens
go to settings , manage aps ,running apps .. then force close FB messenger .. it will be solved that's a bug in fb messenger. u will c

[Q] [BUG] - Not waking up from standby and not switching off!

Hi,
I got my Moto G on the weekend (Unlocked from Tesco Mobile for £2.04, thanks ebay)
However, on one occasion, the phone would not turn the screen off until I held the power button for 10 seconds to reboot it.
But more often (a few times every day), the phone will not wake up from standby until I do the same to reboot it. This morning this alarm clock to fail, so this could be an issue.
Does anyone else have the same issue and know of a fix?
Thanks!
Whichs apps do you have installed? Are you rooted? Did you already try a factory reset?

Do the issue exist if you don't add a Google account? Have you restored old settings through Google backup?

I havent restored settings after a reboot, but i have noticed that I get reboots when I am editing google contacts on the phone....
Crappy sleep of death issue .... Seems moto g is having battery issues...
Mm not battery issues its just SW issues.
Simply fixed but will need an update.
Little tweeks like on a phone call when i move the phone away from my ear to open dialer to enter details on an automated service the screen won't come on until I press the power button twice. Once to lock and once to unlock. Then I can bring up dialler
Its due to all the little refinements in power management but it will get fixed.
I personally can live with the little niggles just now for the amazing 3.5-4 hours screen on time I'm getting.
Yest under heavy mobile data use it went a full 14 hours with the 3.5hours screen in time. It was great because I basically done all my Christmas shopping on my phone and checked store prices when out.
If its rebooting often enough I would do a fresh install and start again.
THE BIGGEST thing I found that made a difference in this phone and I think moto should highlight this is:
Do not import previous phone settings on initial start up. This somehow beings weird and wonderful phone settings over and seems to play Havoc with the overall performance of the device be it battery life or connectivity.
I ended up wiping the device in factory reset and on the section on initial set up about backup and restore I unchecked the second option of restore my device settings. Left everything else and since the phone has worked as it should.
My only issue is the power and volume keys location in my car holder means it can be powered off by the holder doh. So I'm looking for a new one which doesn't hug my buttons lol

Thanks for your help guys, I was still getting random sleeps of death and random reboots so I took the device back to tesco.
They were quick to replace it and I will let you know if I am still getting these issues.
Don't import any old settings, do it manually or you could (if you have the software) do a migrate from My Backup Pro, which I used to migrate pics, contacts, call logs & sms from my old phone with zero issues. My phone hasn't rebooted or had any issues whatsoever. I suspect you just had a faulty unit. Mine is an unlocked tesco16gb too.
rare problem

Defective?Gnote acting weird, auto doing things then hangs up.Help!

Its been my second month with my gnote pro 12.2 and im starting to have problems. First there will be some random press on my screen, ramdom apps will just pop up even tho im not touching its icon. Letter "N" on screen keyboard sometimes doesn't work, when im typing very fast it'll skip the letter "N". When im sliding it side to side it'll bring up the whole slide page even tho im just using one finger. The slide effect won't go through, i have to slide the whole page from left to right or vice versa. The worst thing that i experience is its like its acting that something is tapping on the screen very fast you will see the icon up and down really fast and you really cant do anything to stop it but to wait until it hangs up. cant shut it down, back and task button doesn't work. Home button works but can't shut it down, itll just reboot it self.. It's driving me nuts coz basically i left my laptop at home so i have to work from my note and right now im working on a site.
My device is on full stock, i haven't done any tweaks on it. And im using the wifi version SM-P900. I recorded a video of my gnote pro 12.2 using my g3 and pardon me for the quality since i have to convert it coz the file is so huge. It is a long boring 8 mins video showing my device is acting weird.
TURN OFF THE VOLUME (i can't find android video converter that removes the sound).
0:44 - you can see that it change the highlited email even tho im not pressing anything.
1:02 - its brings up the whole page screen. Im just using 1 finger to slide.
1:20 - menu button doesnt work. It hangs a bit and pops up a balloon.
1:35 - this is where it started doing crazy stuff.

Auto brightness on the camera of your phone made it hard to tell since the rest of the scene was too dark so answer these few questions: Do you have a case on it? Does that case turn on/off the screen when opened? If you do have a case have you tried reproducing the results with the tablet removed from it?

Seems like it was protesting to having todisplay the image of the Apple building...
In all seriousness though, could you turn on 'Show Touches' under Developers options? (Tap build number 7 times under About Device if you can't find Dev options.) It may have phantom touches.
And try the above suggested solution of detaching the case if you're using one.

Thank you very much for the respo se. No i don't have the case for my note im using slid on pouch for 12" notebook to keep it safe i stead. I never accide taly drop it either. Im also having random error message like "can't arrange alphabetically" sometimes "internal server error". I also got very few apps installed si ce im usi g this device as my laptop, i needed every storage space of this device, what im using most is hancom apps and autocad also chrome, default email apps a d sometimes skype.
Im not gonna edit this message so you can actually see how letter "n" misses.
Im using the default screen keyboard of the device. Tho the problem is not present if im using bluetooth keyboard. Im planni g to do a factory reset but the problem is i can't do that till i got home.
I just hope that this is more on software issue than hardware issue. Also, it happen often but randomly so i can't figure out what apps causing it.

Yup, sure ill turn it on and observe, thanks for the idea.
That rules out the case issue. These tablets are sensitive to magnetic fields and will act up in the presence of magnets, that's why i mentioned it earlier. I was careful in how I asked because some will be in denial about whether or not their case has any magnets hidden within the case.
If your tablet is indeed showing phantom touches the next logical step would be to factory reset and observe the tablet for a while afterwards. You'd have to reinstall all of your software though so make sure to back up all of your files first. If you do go this route I'd suggest refraining from logging into your google account when you set up the device from a reset OR if you do log in, don't opt into auto backup/restore of the device. This will keep the device from installing previously purchased software making it easier to monitor it BONE STOCK to rule out the chance of your issues being software related. If you can do this and the tablet has issues bone stock then it could be a hardware issue with the digitizer . .

The only problem right now is i can't do that till next week. Or ill start to upload my files with dropbox and ill just borrow a laptop. My main suspect actually is google chrome, this month i think i receive 4 updates with chrome and since then i started having this issues. I really hope that this is just software issue, sammy cust service here in ph is absolutely ridiculous.
Thank you for giving me ideas

If you suspect it's chrome, go to settings > application manager > all > chrome > erase data and cache, and then uninstall or disable it. (depending on the available options).
As for the keyboard, can you give swiftkey a try, see if that has the same issues?

Yes i think that's the culprit. Im in the middle of backing up my files now coz i decided to go for a factory reset. Ill observe how my device will behave on full stock without users apps installed.
As for the keyboard, yes ill install swiftkey.. somehow it makes me ask myself, why the hell am i still using the default keyboard?
Anyway, thank you for all the inputs, ill give it all a shot.
After going back on full stock, no apps being installed, and testing for 2 days, sad to say but the problem still exist. Il give it another try and will flash stock rom, this will be my last resort and if things still not fixed, maybe its time for this beast to have its repair and vacation.

no respond from touch screen

Hi, for the past two days, I have been having issue with occassional lack of response from the touch screen. Whenever I pressed the power button for a few seconds, I got a list of options: power off, data network mode, flight mode, restart. However, there was no respond when I touched he screen. I just pressed the power button slightly, went somewhere, tried again and the device resumed to normal. what is happening? is there a way to fix this issue without rooting ?
You are without a doubt the unluckiest user I've ever me. Is there anything on our device that does work?!
Mine does sometimes lose touch responsiveness. The pen still works, but touch does nothing. A reboot usually does the trick.
it was working nicely but suddenly I got maps has stopped, follwed by andoid system has stopped message. Then, on the past two days, lost touch screen response. Not sure if the following are related o my problems. 1. I use iBalls as protector of the corners for about a week. Yesterday, not two days ago, I joined the Japanese docom mobile phone services. They made some changes in the settings to allow me to use their 4g and wifi and phone networks. After that, I lost touch screen response more often than two days ago. Is doing a factory reset a good way to solve the problems? I recall that there were two firmware updates.
Well, if one of the corner balls touches the screen, that could kill the responsiveness.
As for the changes they made, those were probably the APN settings. They're required to use the internet and vary per provider. Pull out the SIM, see if that makes a difference.
A factory reset usually solves system errors.

I recall that they did some APN settings. They also set up the Mail connection. Before factory reset, is backing up using keis the best way? I don't kow if keis also backup whatever that have been causing the issues.
The balls just slightly touch the corners sometimes. Do you mean if by chance more than one ball touches a corner, this could confuse the system and cause a lack of respond? Sometimes even there were lots Of battery power, the system did not wake from sleep. It was like there were no power. I had to put the device away and waited for awhile before I could use the device again.
Any backup brings the risk of backing up the issue as well.
I recommend using Helium, back up only the app data you can't live without, do the rest manually and start with a clean device.
And yes, I did notice that if something is constantly pressing the screen, it gets confused sometimes. I had it happen with (you can laugh) my cat, she had her paw on the screen, messed the whole control up.

Well, what apps or games do you not want to lose the data of? Is there a game whose progress took you months to achieve, things like that.S Note and the like can all be synced through your Samsung account, by the way.
Thanks. Will Samsung's software also backup the mails from the mopera email account I got from my phone provider?
Not sure if this is related. I did not use the iBall protector yesterday and there was no problem with the touch screen's responsiveness.

I don't know, I never use KIES.
Test it without the balls for a few more days, if the problem doesn't come back, you've found the culprit.

I've had this happen to mine a couple of times, the hardware buttons still works (even the capacitative ones) but the screens refuses to do anything. The first time it happened was when a small droplet water landed on the screen, and the second time is still a mystery, but a restart solved the problem both times so I suspect it was something I did rather than any hardware issues... Having said that this hadn't happened on any other device I've owned.

Programs sometimes crash without explanation

Hello. I have a problem with my new Mate 7.
It seems it doesn't matter what program is running, but sometimes they just crash without any warning or explanation.
For example, if I recieve a snap from someone and I open snapchat, it feels like a 50/50 chance if the program turns it self off and I come back to the start screen and every icon and stuff has to load all over again.
This happens way too often. It doesn't matter if it's a game or just the web browser. It's all the same.
Sometimes I have to open them and let them crash several time before I can use them. When they first work, they work properly and feels fast and smooth.
Anybody have similiar problems or knows a fix?
no ? no one?

wow what an amazing site this is! I have been waiting almost a month now.
well no one can see the logs or crash reports, wheter you rooted/use xposed/use a not supported sd card or nothing at all. Only thing most peaople coud tell you is to reset your phone but that's probably not the solution you're looking for. There are almost none experienced developers for the mate 7 here on xda but not even they could help you as there are so many factors which could cause the app to crash, it's just an Android thing :|

I haven't done anything to the phone. It worked perfect the first 2 days I got it but then everything crashes.
I don't have an SD card yet.
I switched to Nova Luancher and it worked fine for a couple of days before everything crashes at random again.
There is no crash report when it happens but everything has to reload after it crashes. It doesn't matter what kind of app it is. Everything is just screwed up.
well I'm really sorry for you then..
just get a sd card and back up everything, then reset the phone. as long as there aren't that many apps n stuff to recover I would do it asap, I managed to softbrick my previous devices quite a few times and believe me, reinstalling all your apps after months of usage without an backup sucks even more..

Laggy Pixel - almost impossible to make/receive phone calls

Hi all,
Pixel 1 after one of the latest updates turned into almost unusable piece of junk ;/
I do not know if this is OTA update issue or hardware fault, but phone must be restarted frequently, otherwise is almost impossible to make phone call - phone is laggy, screen doesn't respond properly, sometimes must hold power button for several seconds to force reboot, as it is not possible to reboot using the screen.
After reboot seems to work fine until someone is calling - when I answer, the caller cannot hear me and I must restart the phone again to make another try. Sometimes it work and I can talk over the phone, but mostly don't.
Phone never been rooted or anything, always updated with the latest OTA software.
I did factory reset - no change ;/
Is there anything I could try? I was thinking to try to go back to older software, but I'm not sure if this is software issue, as didn't found any other posts on this forum describing similar problems.
It is unusable anyway, so I will try anyhing.

Ive updated to latest ota on pixel 1 and had no problems so far. You could check the dialer app is set as default dialer and all permissions are granted and maybe clear the apps storage/cache, force stop it and re open it and see if that solves anything? Could also check background apps and running services in developing options to see if an app is banging out the memory causing it to lag?

if you already did factory reset then it must be a sign of motherboard is dying soon or bad nand chip. motherboard failing on pixel is very common but it happens to less than 1% of people. there are plent of threads on reddit/xda on this.
What's the status of your Pixel? Is the bootloader unlocked? Rooted? Did you have any such problems on the December udpate?
As mentioned - I did factory reset as I thought it may help cure the problems, but it didn't.
I have never unlocked bootloder and phone is not rooted. All standard here.
I have the latest update installed and same problems persist ;/
I'll try another factory reset today.
