Strange touchscreen randomness and glitches on LCR v1.7.2?

[Guest britbloke]

Hey everyone, brand new to the Acer Liquid E (I originally bought one cheap with the plan to sell it on, but got a little hooked on it!).

Anyway, I've flashed to Liquid Community ROM v1.7.2 and everything was good for a short while. Then, when running an app I was getting a ton of glitches; notification bar sliding down really randomly and very fast, homescreen panning left and right quickly. Basically just random swipes, selections, ect as if someone was playing with the phone, but it was happening very quickly. It's almost as if the touchscreen has a life of it's own!

It also happens when I'm using Google Nav without me actually touching the screen for a few minutes.

I've tried booting into recovery and wiping cache and more, but it didn't solve the problem. What I usually do is wait a few minutes (it can continue for 2 or 3 mins, maybe more) and then it seems to settle down. But then it can start again without warning.

It was driving me crazy so I flashed with Xian v0.9. It has been a lot more stable in the few hours I've been playing with it, but it did do the "glitching" once on me this morning.

Is this a common problem with the Liquid? Any ideas on how I can fix this?

strange.. been using mine for six months, and this never happened to me...

Really? I'm going to try another flash tonight back to LCR 1.7.2. If it happens again I'll video it.

good luck with that... it could be because lcr was designed based on eclair leaks and u are using liquid e.. but i don't know, it could also be something else.. if the problem persists, consult malez

If you have the Liquid E, give my kernel a shot and flash it. It might help a little with the heat.

Reinstall LCR 1.7.2

You sensivity must be too high and you screen is too sensible

By default sensivity is set to 75

the less the value is, the more screen is sensible.

You can try to reduce it using this command from your computer

adb shell sensitive.sh 90

If the screen does not respond well, descrese the value

if the screen is to responsive, increase the value

Have you installed a "plastic" protection on your screen (sorry i am not sure of the word) ?

I have seen this king of problem only one a phone without protection.

Never happened to me

What is your baseband version ?

try cleaning the screen really well, maybe a mild detergent on a cloth

I used to have that hapen with my iphone 2g if it got dirty

Thanks everyone for the suggestions. This is a great forum!

I don't have a screen protector, no. I will try to reflash LCR again tonight and adjust the sensitivity as you suggested.

My baseband version is A1.04.01.01

[Guest scrap2434]

I had the same issue. It was screen Sensitivity. Adjust it to 75/75 and all is good again

LCR 1.7.2 had just been released recently. How come you have used it for six months?

I think he has used his Liquid for six months...

exactly!!

It might be a kernel bug.

Specifically with binder.c

I've been using my own built kernels and noticed that this might be one of the causes.

[Guest britbloke]

I used malez trick of reducing the sensitivity to 90 using adb and I haven't had the problem since, touch wood.

I wonder why this isn't a more common problem? Is it because I'm using the Liquid E? Maybe the screen is slightly different.

Hey man, this happened to my phone too, and I've tried malez's trick and it works wonders.

[Guest xaueious]

Dunno. I never had your issue until I messed with my kernel's binder.c

[Guest Gryx]

I had it too after changing the sensitivity. Just changed the values and could use my phone normally again.
