Touch screen problem.

My brother just bought a wing. Everything works fine except for the bottom left corner of the keypad. The "*" key works once then if continuous it will show p or w. Works if you wait 2 seconds before depressing *. Also when screen is depressed, it bevels in the middle like it's touching the lcd. Broken digitizer? Anyone else experience this problem before?

Touchscreen doesn't work

Hello,
I've got a problem with my qtek s200.
The touchscreen only works when I press the opposite sides of the plastic case. Y mena buy opposite sides the side with Comm and Camera buttons and the side with the Standby buton and the pen.
So, I must press both sides with one hand, and then the touchscreen works perfectly.
If I don't press the plastic case, then the touchscreen doesn't recognise the mouvements of the pen or my fingers on the screen.
For example, in Start menu, I put the pen on one item, and the item appears in blue (select), but when I raise the pen (so, no contact between pen and screen) the item is deselected and the selected item is the last one (always the last one).
So, I imagine that there is a problem with the plastic case, which could press the screen on the lower zone, but I'm not sure in how to repare it.
Thanks you for any help.

anyone have the touch screen alignment problem or it's just me?

try to download "multi touch paint" from the market.
draw a line across near the bottom of the screen. you'll find it always below where u touch, compare to a line draw across the top of the screen.

Yup seems to be your the only odd-ball, just kidding i couldnt draw the thing either haha.
I get exactly the same behaviour when I draw a line right over the touch-buttons and when I do the same at the very top edge of the screen, can't see anything that looks misaligned.
I have that issue,too.
That happen most likely when I turn my phone side way and try to access the bottom icon on the home screen. The touch screen has 30% chance to be out of alignment.
the line i draw just slightly below where i touch, that is around 2mm, sleep/reboot won't fix it.

workaround for 1cm dead area of digitizer?

The bottom 1cm of my touch screen no longer works.
I'm getting by using pie and rotating the phone but holy cow is it awkward! Is it possible to:
Recalibrate the touchscreen so that it thinks I'm tapping a bit lower
Or
Constantly render an empty black bar down there so nothing shows up and needs clicking in the area
Or
Replace the digitizer only (don't want to buy a new LCD)
Or..
Anything?
Thanks!

[Q] Phantom touches screen issue

So I've been getting ghost or phantom touches on my phone for the past few weeks. I couldn't figure out what was causing it because I've never dropped my phone and it never got wet. The phantom touches only appears down the right side of the screen in almost a straight line. It doesn't happen all the time and I thought it was random but I got it to occur at a successful rate. If I press down on the top left corner of the screen, it would cause the phantom touches. When I press and hold down the top left corner of the phone, everything is fine and no phantom touches appear. I decided to tighten the screws on the top left and it seems to have made it a little better. I'd have to really tap on the top left of the screen to make the phantom touches appear again and it doesn't occur at a 100% rate but it's still occurs.
Anyone know what is causing this? I thought it would be a broken digitizer but it doesn't make sense that tightening the screws would cause the issue to almost fix itself. Problem with the geomangnet? I'm not sure what that does really.

Put 2 (or more) fingers on the screen of your Note 3 in a horizontal line in landscape mode. You can also use Portrait mode with 2 fingers.
Move the fingers slightly about, trying to have both (all) in a straight horizontal line.
After only a bit of trying one (or more) detected fingers should disappear (become undetected) or ghost touch detections should appear.

Thank you for the help and suggestion but I've already tried this. My touch screen is fine in terms of detection. I can put 10 fingers on the screen and it would recognize all 10 fingers. My issue has something to do with the top left corner of the screen affecting the right side of the screen. Like something is loose. When I clamp down on the left corner of the phone, everything works fine. No ghost touches (that sounds dirty) or any of the sort. When I let go of the top left corner, I will some times get ghost touches.

It's not a firmware issue. It's definitely a hardware issue since it starts tapping on buttons inside TWRP recovery. Ah well, I tighten the screws even more and it looks like the phantom touches are gone. Hopefully it stays that way even though I destroyed a screw in the process. Those tiny things are fragile.
if the touch ghost click is in some certain location most because of pollution (mainly chemical), best is use ISO alcohol also use a very tinny sharp blade, like a very thin one and slightly go along side the place that does this, sometimes you have to try both horizontal and vertical, then clean with ISO, do a few times it does alright. it does work on most of touch screen include note 3 as well. I've been in IT and fixing all electronic for last 30 years in New Zealand. if you had problem text me on 021 548484
