Display & Touchscreen Issues

[djbutter]

I've owned an unlocked U11 (US) since launch day, and it's been performing flawlessly until these party couple of weeks.

I started to notice that on occasion, visible scan lines would appear on the display.

As well, touch response would suddenly drop or get really jittery. This causes a lot keyboard typos (i swipe) and accidental instagram likes (due to the jitters!).

The two issues do not always happen at the same time.

I ran that line drawing diagnostic test, and it does appear to fail every so often.

I've babied this phone since day one, so it's really frustrating that this is happening.

I'm wondering if anyone else is experiencing the same issues. Could it be software-related?

Yes. I believe HTC needs to do a update.

Yes. I believe HTC needs to do a update.

Yes, you are getting the same problems? Or yes, it's software?

I also noticed this behavior. In earlier Firmwares I had this way more often than in the actual one, but this scanlines appear from time to time. Seldom but they appear. Contacted HTC already, they believe in an software issue. Let's look what the time brings.

I think you can force them if device sleeps and you cover the screen completely with your hand. If the device wakes up the scanlines are noticeable.

the scanline thing happens with all of them, its not a bug specific to your device, sadly its so hard to pint point and report

No it doesn't happen to all of them, I've never seen this issue once. The scanlines anyway. The touch screen is overly sensitive so if I don't move my thumbs away as I type, it acts like I'm still on it. It's not in glove mode either, that would probably be unusable.

Looks like I'm not the only one with touch screen problems:

Guys can you do the screen line test and see if hitting two sides of the screen in succession as if you're typing a message joins up and draws a straight line?

It does. Totally repeatable when the taps are super close to being at the same time.

Turns out it's normal - my brothers one plus 3 does the same.

I cleared my cache partition and went back to using the original HTC keyboard to see if it helps. It does seem a bit more behaved at the moment.

Well its definitely doing it with SwiftKey. I've been getting really aggravated because it will delete words as I type, close the keyboard occasionally... SwiftKey has a gesture to delete words and sentences and guess what that gesture is? A line on the screen.

 

[Doughnut]

Hmm, I get what you're saying. But my brothers One Plus 3 behaves exactly in the same manner but doesn't have the weird jitters.

I'm thinking it's an Android thing to join the two touches on a software level, however if the digitiser is recording a straight line touch end to end that's a different matter.

Here's another idea, enable the pointer location in the Dev settings and see if you get a straight line with that when touching in succession - I don't, and hence that's led me to think joining the two touches on a software level is intended.

Its not intentional, they will undoubtedly fix it at some point. They had to fix it on the Evo 4G too but it was not as bad as this...

Just updated to 1.27. Previously in 1.13, tested tapping using sketch app, there were 4 horizontal lines produced during 50+ taps. Now it's 0.

6hours in, I feel typing is better now.

I remember the same thing when HTC 10 was released and I had the same issue with over sensitive screen. After couple of initial updates everything was fixed so like someone already noticed with 1.27 base HTC is refining this speed deamon and they already addressed this problem

 

[Doughnut]

That's very interesting. I wonder why my brother's one plus 3 behaves in the same way, but doesn't cause any adverse effects...ah well there's hope. Thanks for the update.

HTC phones aren't the only ones with this problem. I have had different manufacturers that had the same problem.

This is very promising!

Swiftkey is amazing because of those 2 gestures but I've had lots of problems with them on the U11, especially when the keyboard is closed and I end up pressing random buttons that were behind the keyboad. It's a really bad and dangerous issue. The only fix before 1.27 is to just disable the gestures.

Is the typing still OK? And can anyone else on 1.27 confirm if the fix is good? Thanks

Used to make ghost swipes here and there when using SwiftKey. Now it's not happening anymore. Not even once since 1.27
