Is thermal throttling disabling the touchscreen? - Essential Phone Questions & Answers

I'm having a touchscreen issue with thermal throttling on my essential: the touchscreen becomes completely unresponsive while the rest of the phone is functioning normally (active videos keep playing, the volume buttons perform the expected actions). When I hit the power button to turn the screen off and then wake up the device the touchscreen works - but only for a short time, seconds or less. It always happens when the phone is warm, but not nearly as lava-hot as my LG G5 or Galaxy S3 used to get. So I put the phone on an ice pack briefly, and the touchscreen always becomes responsive again.
I'm on build NMI64C.
This thread (https://forum.xda-developers.com/essential-phone/help/agressive-thermal-throttling-t3672225) talks about overly-aggressive thermal throttling on the phone. This thread (https://forum.xda-developers.com/showpost.php?p=73692472&postcount=8) mentions "random" freezes that resolve temporarily after turning the screen off and on again. This thread (https://forum.xda-developers.com/essential-phone/help/touch-screen-unresponsive-t3674192) talks about unresponsiveness, but it resolved for them after the update.
Anyone else having this issue, or any ideas how to fix besides carrying around ice packs?

HD2 oudside in the cold.

I tested out the HD2 outside in below freezing temps, and it really had a tough time registering my finger presses. It took about 5 minutes, before it could register properly... Anyone experience these issues?
Yes, and the wind keeps pressing things which makes it almost useless. I'm hoping some of the hints here on how to make it less sensitive will help but I haven't tried it yet.
I've noticed the "ghost" pressing (the screen registered a LOT of presses when my fingers were nowhere near the screen) of the screen too. I also contacted HTC support on the issue, and they said it was not a known problem.
So, again, I'd suggest that if you're experiencing issues with the screen in cold temperatures (finger touches not registering, "ghost pressing" etc.), let HTC know about it!
i got that kind of ghost typing too. pretty funny to watch but annoying when you see its deleting mails, answering sms or calls people ... will contact htc as well to let them know.
Confirmed here too. Though I thought it was caused by constant rain/snow here in Moscow, which fell directly on the screen when the ghost tapping occured.
Yeah I get the ghost tapping but only after i've been in a call and hang up, it then starts doing all sorts of things by itself normally ending up with dialling someone!! :/
I dunno about the ghost-typing but isn't it a common fact that capacitive screens don't work well with low temperatures?
That's a capacitive touch-panel "Feature" . HTC can't do anything about it (besides lowering the screen sensitivity).
edit: Umiss beat me to it lol
you can lower the screen sensitivity either by installing the new 1.48 rom or using the cab from the hints and tweaks thread in opening couple of posts. Should help.

[Q] The LCD Backlight comes on but no graphics...intermittently.

This problem recreates multiple times per day. It seems like the LCD gets powered, but there is no graphics signal.
When I turn on the tablet the LCD Backlight will come on, but there is no graphics on the screen. At this point, I cannot turn the LCD off by using the switch and there is no other action I can take.
I have to wait until the LCD turns itself off (approximately 20 seconds) before attempting to turn it on again. It typically works fine the second time, but not always.
I have called Google and they have issued an RMA, but I am curious if anyone else is experiencing this issue to determine if this is truly an isolated issue.
Thanks.
I began testing with a Bluetooth keyboard and have see the same behavior when waking the tablet up using the keyboard. This would eliminate it being anything to do with the physical power switch.

touchscreen unresponsive after opening slide cover

Hey guys,
i noticed something strange on my tn7.
Sometimes (maybe 50% of the time) when i open the (original) slide cover to wake up the screen, the touch screen is very unresponsive.I can touch, but it notices only ~10% of what i am doing and is extremly laggin. when i then turn off the screen with the button and turn it on with the button again, everything is fine.
Also when doing this i have to wait for the screen to go off completly - if i wake it when the backlight is still on but the screen is black, the issue stays.
This never happens when i wake the tab with the button though, only with the slide cover. Thats what is kinda strange i think..
Anybody got an idea on how 2 fix this?
Running rooted Stock Kitkat.
Thanks
This is a problem that has existed since this tablet was released and persists still to this day. All you can do is cycle the screen off/on with the power button, unfortunately. Seeing as how this hasn't been solved in the last 10 months and Nvidia is showing signs that they're abandoning this tablet to focus on the Shield Tablet, it will probably never be fixed.
Screen lag
I have a similar issue on mine. I've had mine now about six months and it's very intermittent but at certain times, especially when the battery is low, the keys down the left side lock up and become unusable. I bought the tegra note 7 because of the stylus which I prefer to touching the screen with my index finger, but I don't much like the stylus itself which could have been made of better materials I think. I also find that sometimes it doesn't register clicks, then it will be perfectly ok for a little while. I had hoped with the tegra 4 and the much hyped stylus it would be very responsive but it's inconsistent. Anyone else recognise these flaws?
I also get this intermittently but only ever when waking it up with the cover, its never happened when turning on with the button. When it does happen a quick off and on with the button resolves the issue

5.1 Touchscreen unresponsive with flip cover

EDIT: ok, touchscreen unresponsiveness after long standby happens due to flip cover. so this could be a major bug in the 5.1 update that needs to be fixed. i hope we will get a few ota updates with fixes for our problems.
yeah, as the title said, i can't use my tablet after it was in deepsleep/standby for too long in android 5.1 lollipop.
Scenario: after long standby/deepsleep time i pressed the power button to turn the screen on. the lockscreen (swipe only gesture) appears. i want to unlock the device by swiping up but it doesn't work as if i didn't even touch the screen.
only workaround for me at this moment is to hold the power button for a few seconds so it shuts down (NOT Force reboot, it still says "shutting down" or something like that). after that i turn it back on, let it boot until it finishes. now the touchscreen works again.
short: long standby/deepsleep equals touchscreen completely unresponsive
rebooting equals a workaround solution that is really anoying for me everytime
did anyone experience this problem, too?
does someone know how to fix this?
EDIT: BTW everything works just fine and runs really smooth except for the unresponsive screen while too long in standby.
it could be that my flip cover causes this to happen.
I CANNOT confirm anything yet.
i will try it a few times more with flip cover on top of the display and without the flip cover on display. (could be bad calibrated magnetic sensor or just bad programming overall)
maybe i will know more after that. i will report back in this thread if anything happens.
seems to be solved due to clean restore of 5.1 (READ FIRST POST RED COLORED EDIT LINE)
back again, thought it went away. in the last hours the unresponsiveness bug happend again (2 times; probably due to flip cover)). my thought is that nvidia went on to the flip cover bug from kitkat, tried to fix it and made it worse instead of getting rid of it.
OMG, really? This bug not only still exists but has become even worse? Ridiculous... glad I don't even use my cover any more... I'm not even sure where I put it ^_^ It's stuff like this and the issues with the Shield Tab that kept me from buying the Shield TV, even though I really really want one.
not flip cover issue... its happening ever since i updated to lollipop. only stylus works and finger touch is unresponsive.. sometimes the stylus also doesnt works
Same problem here Blaze! Sometimes finger touch is unresponsive, only works with the stylus! This is terrible [emoji17]

G4 Digitizer problem?

I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.
Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.
I had a similar problem and was able to send it in under warranty and get a replacement phone
G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?
