Hi folks,
Does anyone ever get small periods of the touchscreen becoming un-responsive, for a few seconds?
Thanks

XDA Mini (Wizard Screen Issue)

My XDA Mini has a screen issue.
Only part for the screen (the middle) has stopped responding to the touch pad.
How do I fix this, has anyone else had it?
Cheers
Max
My Wizard (O2 XDA Mini S) has just developed this problem. The touch screen does not respond to touches around the middle of the screen. The outside edges of the screen work fine however.
I've had it for about 4 years now though, so I suppose its lasted well really. It's a G4 and I installed a WM6.1 ROM on it about 6 months ago (which is awesome btw, makes the phone sooo much better / faster!) but I don't think this is related to the problem.
Any known fix for this? I think it's a hardware issue since I also have the problem where upon opening/closing the keyboard, the screen goes white with multicoloured vertical lines and the phone emits a high pitched noise (have to put phone into standby then wake it up again to resolve). This, whilst annoying, I can live with, but not now the middle of the screen no longer responds to touches
I read somewhere its to do with the ribbon cable that connects the screen and main board, its gets trapped or worn over time as the keyboard is slid in and out. So I guess the touch problem is a more severe symptom of this? Can it be fixed?
Also a point of interest is that I keep the phone in the case a lot of the time. Could the magnets have possibly affected the screen? Anyone else with this problem keep the phone in its case a lot?
Thanks in advance,
Jamie

unresponsiveness

I have a problem:
Every 10-15 touches in the screen of my Leo, I get an unresponsive touch, I mean that though I touch the screen, no action takes place!
Does anyone know the reason?
Thanks guys!

adjusting the touch screen sensitivity

Hi,
I played around with a Asus Transformer...I'm getting my own soon (very soon!).
Comparing it to the touch sensitivity of xoom and iPad2's, the Asus doesn't seem to be as sensitive. I'm a novice when it comes to Droid. Is there a setting to change the sensitivity? Sometimes it seems like I keep having to tap something again because it didn't take the first time.
I'm hoping it's a software adjustment, and not a hardware limitation...
I've search the forum where some people were having actual issues with the touch screen not responding or not responding in certain areas. That isn't my question - the screen responds, just not to quick/light touches on icons.
Thanks!

i dont think there is any setting to adjust sensitivity. Ive not tried the other pads but ive never had any problem with lack of sensitivity on my TF.
Maybe once the devs really get into the TF there might be some tweaks possible.

[Q] Touchscreen Latency (possible driver problem)

Hello,
Lately I have noticed that on my G2 (ls980), the touchscreen latency alternates between very responsive (very low delay to register touch/swipe) and very unresponsive (longer delay to register touch/swipe). Originally I thought it was just a problem with the ROM I was running, but I have encountered this issue on every ROM I have tried (including stock). It happens randomly, but usually when the phone first comes out of sleep, it is responsive and has a low latency. Within the next minute, latency increases.
Could this be kernel/driver problem? Has anyone else encountered this issue? From what I gather, this is NOT the same touchscreen sensitivity issue that has already been discussed.
Thanks!
I found the g2 (d802) touch just not adequate for a flagship phone. Sometimes you have like a feeling of poor sensitivity, and the delay to register the touch is greater than Nexus5 (side by side comparison). It's good, ok, but sometimes you can miss some tap because a too low (or brief) pressure on the screen.

Yes, this is common as of what I have heard and read on the forum. A quick fix is to press the power button and wake it again. It's strange but works for my 802 on both stock and omni.
Another interesting thing is that touch latency even at its best is quite far from the best phones on the market today. Look at this thread. http://forum.xda-developers.com/showthread.php?t=2706200&page=4
What does HTC do so much better?
