Touch screen responsiveness problem? - Moto G Q&A, Help & Troubleshooting

Well this is weird. This morning I woke up and grabbed my G from next to my bed and the touch screen is being all slow and not responsive. I can't swipe left or right without doing it very slowly and deliberately. Same thing with bringing down my notification drawer.
Its making the phone near unusable. Even to type this all out I couldn't use Google keyboards swipe typing feature and have to hit each individual button really slowly.
Anyone know what could be causing this?

Install this and see how it behaves https://play.google.com/store/apps/details?id=multitouchpro.tests&hl=es

Thanks for that useful little app. It registers all my fingers fine, and its good if I swipe slowly, but if I swipe too fast it loses my finger for a second, which I guess is why I have a problem swiping.
I have no idea what's causing this still though since its been working fine for the past month.

Have you tried turning it off and on again?
Do you by any chance have the charger plugged in while doing this? (My nexus 4 screen acts that way when I connect the wall charger)
Have you tried resetting it?

It's not plugged in, I did try rebooting it but not a reset. I'll have to give that a try now.

Same here, part of the screen is unresponsive, except if you move your finger very slowly.

I have the problem described by OP if I am charging with a high ampere charger. It is solved by me by turning the screen off and on after unplugging it.

I forgot to update. The problem just kind of fixed itself over a few hours. I took it to work and it was still having the problem, and then I took it out of my pocket a few hours into my shift to check a text and it was working like usual.
I dunno. Magic I guess.

Could be that the cpu got underclocked for a while?
Using any cpu overclocking apps?

Guy who did a waterproof test on the Moto G encountered the same issues you described. As the phone dried out the screen slowly came back to life and became responsive again.
I suspect that you have moisture egress into the device, it could cause a strange capacitance differential affecting the digitiser, or even just a short.
Have you used the phone, in shower room, in pocket while exercising. In rain. Taken it from cold outdoors, into very warm indoors. All these things can cause moisture to condense inside the device.
If it happens, the symptoms will reduce as the phone completely dries out...

Facing Same Issue
Hello, I am also facing same issue only when my Moto G is connected to Wall Charger [Be it switched Off or On]. Can any body please help me resolve this issue? Or Do we actually have a solution for the problem stated?

same issue
Hi i have the same issue, please someone knows how to fix it or why it happens ? In my phone the problem appears and solve for itself but after a while the problem appears again

I'm also in the same boat..

still not working
I made the multitouch test and all works fine, it seems like is a software problem but i don't know wich one is failing. I hide the navbar with gravitybox, could this be the cause of the problem ?

definitely your charger I had the same problem when using a generic charger... try a different charger

this behavior happens to me with stock keyboard in whatsapp, after star typing and pressing the "a" key in loop, press the home button and start multitouch test (YAMT) and the screen area that is not responding is where the "a" key is located....
after a while the screen start to response in a normal way...
i tried swift keyboard and guess what.... the same issue again....
this is weird...
note: try to remove the grip shell

Solved,
Okay so I had this issue just now and i got worried, but there is nothing to worry about. The problem is in the charger, use a different charger

my 2 have done this a couple times and I think they were charging at the time. I unplugged the charger but no change. Then I removed the silicone cover I put on and it immediately worked fine both times I did it. I did not turn phone off or reboot. It did not start this trick until I put the covers on. Covers barely touch the screen on the sides. When I replaced cover it still worked until the next time it became unhappy with the cover. Anybody else...................
Update-just checked my other phone. I removed cover w/o unplugging and it did not restore it. Unplugged charger and it was fine. Almost seems like both are contributing to it. more research necessary..........
Maybe the phone just wants to be fondled???????

I'm not sure what causes it but a few people have this issue was another thread awhile back. only outcome was turn off screen and back on and it went away.
I do turn off the screen, but it comes right back after about 5 minutes.

i used to have this fairly often but it's been a while now. i would fix it by wiping down the screen really well, leading me to believe that it might have something to do with grease or something that gets on the screen. not positive tho..

Well, now that i have installed some mods and other stuff it seemed to have stopped. Don't know why the mods would affect it... I will wipe it down though just to be safe.
It's just the way it is - as it's winter now, and it's cold, it happens to me and my friend all the time, when we are using the phone outside. Screen off and on and it's working for another 30 seconds
yea when its cold outside mine does this as well +4C and lower. I took it apart and re seated the connectors it made little to no diff. when its warm i have no issues at all.
Could also be something on the screen itself - even a screen protector that gets damaged could cause an issue.
Also a case could cause the problem - I've had similar issues with my case/screen protector interacting with the screen.

The same thing is happening to me. I thought I was going nuts! But yes, when it's exposed to cold temperatures (35 degrees or so and lower), the screen can develop a mind of it's own. Kind of sucks in Wisconsin!

I have had this problem with the both the new Q LTE I received when the Q LTE launched, and also with the refurb unit I have received from Sprint.
Is there an explanation of the issue and a fix?
Should I swap it out at the Sprint store for another refurb?

[Q] [HELP] Scrolling Problem

last night, my phone was overheating. and then i'm trying to cool it down by putting it in front of a fan. when i use my phone, my scrolling is error. it stops when my thumb/fingers is not touching ( do you get it ? :silly: ) . on a normal phone, the screen keeps scrolling even if my finger/thumbs not touching and slow down until stops. but not with my phone. it just stops without slowing down...
can anyone help me ? :fingers-crossed:
sorry for my bad english
Try restarting??
And JB has higher inertia while scrolling. That means if you scroll lightly, it will stop very fast, unlike Gingerbread 2.3.x.
Also, a possible cause might be that you were charging. XL has a slightly aberrant scrolling response while charging, most likely due to the interference caused by the charging battery.
Yes. It worked
Btw, how did you know that xperia L has problem with charging?

Hi!
I noticed this problem with mine too. I was charging my phone and using it on Facebook. Scrolling worked fine but when mi finger was on the screen (just touching the screen, no scrolling), the image went up and down. It looked like the screen didn't know what to do.
But I was not using the charger given in the box, I was using an older one given with my Xperia Mini Pro from 2011.
When I use the charger given in the box, there is no problem.
I've seen this problem on X10 Mini Pro too.

I don't know where it comes from, sorry.
as far as I know, it happens with all chargers. But maybe it just escapes attention sometimes? The charging battery affects the capacitive touchscreen response.

When I saw this "problem" I let the phone charging with my "older" charger. But when it was finished, I tried it with the new one. I went on every application that need to scroll but all was right.
It may be something with electricity quality, like speakers which have interference... (That's just an idea)
yeah. It happens only sometimes. I suspect when the phone draws considerable charge from battery, and the battery from the charger, resulting in higher electromagnetic interference.

[Q] Erratic Ghost Touches

Has anyone had a problem with their nexus 5 where the screen would randomly start pressing things? It usually happens multiple times and is very erratic. Contacted Google and will send back for a replacement just wondering if anyone else is having this issue.
Yap, me too.
Had it a while back but it seems to have stopped.
Sent from my Nexus 5 using Tapatalk
Never anything like that but what I have done a few times is my palm touches the bottom right of the screen when I reach for the top left corner while right handing it. Coming from an iPhone so I guess it took a bit to get used to the larger screen
I requested for a replacement to Google Play this morning. They send it this evening. I should
get my replacement early next week. Good service I would say.
I'm glad I'm not going crazy! This is happening to me too! Is there any way to resolve this without having to go through the RMA process?
Only While Charging
I'm getting some erratic touch behavior, but only when the phone is charging. I take it off the charger and it seems fine.
I'm not getting total phantom behavior, but when I swipe from home screen to home screen, sometimes an app will get activated. Same with pulling down the notification area.
It makes me think there's a charge leaking through to the display components somehow.
I'm going to give it a week and then RMA it if it doesn't go away.
I have it too
I have it too but only when I connect my USB to the computer...
It's sucks cos I'm an app developer...
Is there any fix for that?

Sounds like a dodgy USB cable or port.
Same issues with my Nexus 4
I notice my issue is mostly when my phone is charging or when I'm using my mobile hotspot. Tends to get extra warm when im using both. Which leads me to believe its an overheating issue (the heat is throwing off the digitizer causing it to maybe think its being touched?) Is anyone else noticing the same?
Yes, but only while on wireless charger and even then only sometimes.
I take it off, push power button twice and it's gone.
I'm also experiencing this if my Nexus 5 is charging using the original Wall charger and cable.
Still no fix for this? Really annoying, I need to unplug my phone to the charger so that I can use it again normally
Same issue here

Vibrate causing screen to auto rotate

I've noticed a few times when my phone vibrates and its pretty much flat the screen sometimes rotates. Not sure if this is a normal thing happening with most phones, I'm assuming the vibrate motor is confusing the accelerometer somewhat.
You can see a video of it happening below. The phone is flat against the table. Vibrate is set at 63 which I believe is close to stock. It happens on 50 too.
youtube: http://www.youtube.com/watch?v=-iuo7zsbCj8&feature=youtu.be
Could someone else try this? The app is free. Just switch to auto and set it to something like 0.999 and repeat. Obviously make sure auto rotate is enabled
https://play.google.com/store/apps/details?id=com.anthonyquarella.vibratetester
I've always found the auto rotate on android a bit over sensitive, just trying to figure out if this might be a fault with mine.
Its done it to me before when my phone was laying on my bed charging

Yes, I used the test your android app and vibrate on short bursts. I think camera lens is tilting the phone. It was on a flat desk.
Ahh sorry was trying to quote the other guy on my phone but screwed up. Thanks for letting me know. my phones in a case and it does the same.

Yeah when it vibrated while laying flat the screen would auto rotate in no particular direction.

Old thread, but it happens to me when I'm playing some games. Vibrates and the screen flicks upside down, then back to proper orientation. I'm holding it in my hands and it's not totally flat either, so it's really getting thrown out of whack for a moment, then re-orients. Doesn't happen in every game, doesn't happen for every vibration, but it happens enough to be annoying.

Nexus 5 screen died today + dangerously hot lower screen

Went to unlock my phone this morning off the charger and the screen is totally dead. Couldn't unlock or do anything to it or even see what was going on, called Google and ordered a replacement ASAP.
Went through the not fun task of doing a nandroid backup without seeing what was on the screen and doing some trickery with screenshots then backing up my entire SD card.
However, here's the strange and potentially dangerous thing that I noticed later when I got home this evening. I went to look at the phone and go to a fastboot flash with the factory images and went to touch the bottom of the screen. When I went to do so, to the little bit of the left of the LED light was a SUPER hot portion of the phone. I almost burnt my finger it was so hot.
Not sure what to do about the issue, I feel like if I just call the support line they won't actually take in my concern legitimately. Any suggestions?
thats something quite strange
let us know what google says about RMA and this issue
Agree, maybe it's just your phone, maybe it's all the batch. Which batch/model do you have?

On my Transformer Infinity, sometimes the screen won't turn on at all. On a few occasions, if I press Power enough times, I get a glimpse of a message saying the Launcher process has stopped, but then my touchscreen doesn't register any input. The tablet is also sometimes running quite hot at those times. The only way I know to recover from this is press the Power button long enough to force a reboot, then everything is normal. Could this be what's happening? Do you know if the phone is still running under the black screen? Have you tried forcing a reboot, and did it work?
As for the hot phone, I've noticed my N5 does get a bit warm when I'm using it intensively (4G, WiFi, Bluetooth, GPS and screen on all at the same time and in use) but not enough to burn me. Could be hard to tell which component is heating up like that since I think it could be the screen backlight, SoC or battery... Do let us know if you find out more.

I had called them and reported the screen totally dead with lines streaking vertically and got a new replacement ordered. It wasn't until late last night when I got back and had the screen on in this dead mode that the bottom was extremely hot. I'll have to call them back and let them know

Yeah, no its definitely dead. There were streaked lines across it, rebooted it multiple times. I ended up going into the bootloader and recovery via adb/fastboot and all that jazz. It eventually just would not work now.
In regards to the hot part I definitely think it was the lower part of the screen. It was quite literally half an inch away from the LED to the left. Was super super hot then once I shut the defective screen off (I could tell by the backlit light or whatever) it wasn't hot anymore after a minute or so.
Is it black/white? 16 or 32? When did you get it?

32gb black version. I ordered it immediately when they announced it that day.
mine gets really warm when i'm doing a TWRP backup then it goes into bootloop after and wont cool down. i have to force it to power off from recovery and let it cool, but i've always seen it happen. i wonder if yours was attempting to boot over and over for hours and cooked itself.....? i have a launch day black 32gb too, running Cataclysm with Franco at the moment but it was doing it on rooted stock with stock kernel
I had to send my 19 day old 32Gb Red Nexus 5 in to LG for the same reason. I was using the phone and all of the sudden had vertical lines and the bottom of the screen got burn your fingers hot. Waiting to see what LG does with my phone. The only thin I can figure is the synaptics chip which controls the screen is bad. Its the only thing in that area that could get that hot. I also noticed when I first got my phone the glass in the same area looked like it had a slight wave in it. Didn't think anything of it at the time. I'll let you know how it goes.
Is RMA/replacement applicable for Rooted and unlocked devices?
I don't believe its an issue with developer phones as long as the issue wasn't caused by something you did like brick it by flashing a wrong radio or something like that. It has to be a manufacture defect to get it fixed for free.

My device issue is related to power button. there is no software issue.
The power button is rattling since from the purchase of the device.
Hope my device gets repaired.
Like I said. Hardware issues that are production faults should be covered.
