So I have the WI-FI version. Since last night the touchscreen has gone whacky. If I press anywhere on the screen one and a half centimeters from the bottom up, I get multiple touches registered, basically I got these zones, specific zones where this issue occurs, I have not found them all. On these zones, I don't even have to press, the touchscreen is super sensitive there that it detects me from rather high up before I even touch it. In any case, it renders the device unusable for me as I cannot type in portrait mode, and just barely in landscape.
Running stock ROM and rooted kernel with unlocked bootloader.
I basically want to find out if this is some permanent issue that cannot be fixed, or something that can be remedied.

About 2 months ago I started getting phantom touches on my screen, always on the right side. In the app Dotty, I could create the touches by moving my finger near the right edge until a circle would appear and start barely moving up and down really fast. This would be the primary touch point and other touch points would show on the screen in Dotty but in any other program all secondary touches were ignored(keyboard, homescreen). This created the illusion of the touchscreen simply not working. To fix it I had to sleep/wake the phone a couple times until it went away. This issue would come and go and seem to be really bad for a day then there wouldn't be a problem for a week. As of now, the phantom touch point problem seems to have gone away. However, the right 1/4" of the screen no longer registers touch. This mainly only affects the P key but is quite annoying. The strip that doesn't work runs from x:287-320(edge) in Dotty. I've flashed, re-flashed several roms and can't seem to fix the problem. Any ideas? Is this a digitizer gone bad? Should I contact HTC/is it covered by the warranty?
Hi
I bought a new RHOD100 and am running Stock WinMo 6.5. First few days the phone worked beautiful. But about a week of usage landed me in this condition.
The screen only lights up with the keyboard is out and not tilted. Other than that, if it's slid in (portrait mode) or when it is tilted up, the screen freezes to whatever it was like when the keyboard was slid out. The touch functions work, I can hear screen tap sounds, and if I click on the right icon things open and close too, but the display remains frozen until I slide out the keyboard and/or undo the tilt.
Any ideas how to fix this? Is that hardware or software?
I have never dropped it, nor exaggerated the tilting.. Can it be the Flex cable?
Definitely hardware... almost 99.99999999% sure this issue is hardware.
I'm betting it is indeed the flex cable. If you're feeling brave, you can attempt to take the phone apart and see if you can find the issue - keep in mind, this is very delicate and tedious work. Need a steady/careful hand and a lot of space! Good tools help too .

Last weeks i noticed strange behavior of my Z1c screen. Sometimes it start to react without touching (gloves mode off). Simply, i don't touch it but it starts to scrol screen or (worse) send some nonsence on Messenger to my friends, which is really annoying.
Also, sometimes, it reacts like one finger is already on screen, and phone is performing pinch and zoom etc...
Also, sometimes home screen or P and E button on keyboard won't work.
All those problems are solved with turning screen off and on, but problems are back some time after that...
Just to mention, i am on stock KK .157 rom, without root or any other modification.
Also, last month or so, air temperature here was over 40°C, so phone heated too much even on light usage, and battery temperature was going up to 47°C...
Anyone can help me? Any advice? Is my touchscreen damaged due to high temperatures or it's just software problem?
Hardware problem i believe. It's a common occurrence with the Z1C
About the automatic message sending thing : whenever your phone is in your pocket and someone calls you the reply with text message option comes up hence it sends messages automatically to turn fix this go to settings>call>reject call with messages>click on the messages and edit it
All the Best
it's not messages app but facebook messenger, and that's only while screen is on. so, screen reacts randomly sometimes.
Yesterday my phone fell from 6 feet. Since then, it's deadly slow.
All CPUs seem to be fine, they are in performance mode, at the right frequency. Temperature is good (below 34°). LCD is intact. Touch layer works perfectly. Absolutely works correctly, but very slowly.
Display refreshes about once per second. With some apps, it slickers.
I can perform Skype video calls with both cameras. But Camera application makes the phone freese.
Some chat apps make screen flicker (blink). If only chat history is shown, the whole screen flickers. If virtual keyboard, only the chat history flickers, and keyboards remains still.
When I type anytthing, letters come on screen very slowly. VERY SLOWLY. After typing 2 lines, I have to wait 10 to 15s for all letters to appear. If I type more than 2 lines of text, some words are dropped (sounds like a 32 bytes buffer).
A few months ago, it did exactly the same (as described above); and then things worked fine again after 3 days.
Today, there is one tiny difference: if I turn screen off (via power button, lock app, or screen timeout), then, pressing power does not wake backlight. Only reboot can give me my screen again. But, apart from backlight, the phone keeps working fine: I can get incoming calls, and redial last phone number using BT earsert, or have video chat.
I presently have that last issue on my HTC Sensation, with yet an other difference: if phone (Sensation) is hot, even a reboot will keep screen off. I have to let my Sensation off for at least half an hour to be able to get screen work nomally. With the M8, any reboot gives me my screen back, immediately, even if phone is hot.
The way my M8 is slow makes me feel like it's missing video acceleration. But since this GPU is SOC, maybe it's an issue on the I2C bus between GPU and LCD ? I have removed and reinserted all ribbons; did not help.
If it was a software overload (what most google answers propose as reason for a slow phone), it would not had fixed itself last time. And it would not happen all of a sudden after a shock.

I have open the phone, dismounted most parts, disconnected all ribons, removed the two main PCB, and remounted it all ... twice, and now phone works almost perfectly. I have a bad contact in the top speaker; it has always been a known weak point of this phone; the connection is bad, and speakers are poor quality; so, sound is a bit low volume, and distorted when I use the device in hand (headset) mode; and sound is poor quality on this side when viewing a movie in landscape mode; I shall change this speaker again later (changed it already 3 times).
But regarding the bug of the day, after complete disassembly and reassembly of device, it works fine.
Hi everyone.
I have recently had my screen replaced. After playing around, i quickly noticed that my keyboard screws up when i start typing.
The faster i type, the worse the problem is.
I checked touch response times and achieves normal times of about 60ms, however, i turned on touch overlay in developer settings and noticed that if i touch opposite sides of the screen quickly (to simulate typing), it would draw lines between the touches as if i was dragging between the two points.
This is what causes my keyboard to do funky stuff and heavily lag when typing fast.
Please note that this never happened before the screen replacement, and a hard reset didnt fix the problem.
Is there any software fix for this, or do i need another screen?
thanks.

I mainly work on iPhones, but it sounds like your digitizer is out of calibration. Don't know if there's a software fix for it, but hopefully this will point you in the right direction. Also I'd take it back to the place you had it repaired and see if they can fix if it's still warrantied.
