[Q] Is something wrong with my Digitizer? - G2 and Desire Z Q&A, Help & Troubleshooting

This is what happens when I try to draw a diagonal line on my phone. Do you think it's the digitizer?
Until I saw this, I thought I would have to reseat/replace the ribbon cable because the sliding mechanism means the cable is exposed and constantly moving. Any ideas?

If you're running an asop rom, it might have come with the "dev tools" app. Try enabling the cursor position and having a go at recreating the bug while taking note of the position monitors.

White screen, cable problems, unusable BA... Please help!! Thank you!

Hi all! I hope I'm not disturbing here, but I'm quite desperate with regards to my poor BA... After replacing the display about a year ago (the touch-sensitive layer had broken) everything was going well, but something bad has been happening for some months now, and I think it has come to the point of no-return...
At first, when I slid the BA open, there would be a point in which a change in the colors on the display happened, as if the the Red and Blue channels worked well while the Green one was dim (as noticeable during the boot process). Then, opening it completely, it came back to the normal state. The situation worsened, sort of "interference" could be seen while opening the BA, the touchscreen would lose calibration after some openings and closings and so on...
Now the worst: when I turn it on, the screen is completely blank and white; sliding it back and forth would once get it to work, but now it is completely useless. About halfway between the open and closed positions the backlight itself turns off and then on again. It is impossible to see anything and it is unusable!! I opened the BA and made sure everything was connected, I re-connected the LCD and the touchscreen cable but nothing changed... I don't know what to do...
Does anyone have any suggestions? Can I try to repair it or to have it repaired, or, as it is a bit visibly used, should I resign myself to saying it goodbye?? Thanks for your patience and help...
News!! I rried to replace the new screen with the old (broken touchscreen) one, and that one works. Save for a problem, the green colour is lightly dim in the exact positions in which the backlight goes off with the "new" but not working display... Does anyone have an explanation for this behaviour? Thanx again!!

[Q] TocuhFlo3D problem!

Hi! I have a big problem with my Rhodium.
I have post another similar thread before but aybody seems to respoding..
I don't know what happened to my phone.
The touchflo3D seems to not responding. in other words the screen reacts when I tap on it, but I can't move or select anything on the screen.
I don't understand if it's a software or hardware problem.
The problem born with a custom rom I installed.
R [WWE|GER|FRA|ITA|NLD] |Feb 12| Energy™-.¸¸.·´¯ 6.5|21916 / 6.5.X|28244 * Sense 2021
after few days of no problem, the screen became as I described, incapable to select anything.
I tried also to move to the settings to disactivate sense but it was impossible with only the keyboard.
I searched on the forum for the solution, but the methods proposed didn't resolve the problem!
So I decided to return to the ufficial Rom.
RUU_Rhodium_HTC_ITA_1.19.408.1_Radio_Rhodium_3.44. 25.27_Signed_Ship
I performed a HardReset before the reinstall of the ufficial rom, but the problem remained.
So I performed a task29, but after the reinstall nothing changed and the TouchFlo seem to be broken.
I followed the guides proposed but I don't think I commited something wrong...
I suppose is a problem of the software because, I repeat, the screen react to my tap when is in minimum light.
Please help me because I don't know whato to do...
Tnx to All!!!!
Is the issue *only* with Touchflo? Can you tap on the Start menu and bring it up?
I'm confused as to why you say "the screen reacts when I tap on it, but I can't move or select anything on the screen"
How can you tell if the screen reacts?

Hi! No I can't tap on the start menù and when I tap on any icon on the screen nothing happens!
What I meant with "the screen seems to react" is that (sorry for my English XD!) before the screen goes black, the light goes high to low, ok?
when the screen has low light, and I tap on the screen, the light goes to high, so it seems that the screen can react to my tap.
tnk you very much for your response.
If I wasn't capable to explain correctly, please tell me 'cause I'm a little worried for my phone!
Bye.
i don't want to bring down any hope left, but if it does not respond to anything you do, i think your phone has just lost its flat cable. It might be broken and fixing it up would be a total pain. I would bring it back to where you bought it. Contact me through pm for further details, if u're still wondering what does this mean.

This sounds either like a broken / damaged ribbon cable (the "flat cable" the previous poster was referring to) or a damaged / broken digitizer.
On my old phone, the digitizer slowly broke - first the accuracy of the touchscreen would slide, then it got to the point where it wouldn't register 'on screen' at all, even though the phone could still tell I was tapping the screen because the backlight would come on etc, just as you describe.
Replacing the digitizer will cost money, but if you're going to do that find someone good at doing it! And also consider getting the device checked out and replacing the ribbon cable too, it's probably one of the most vulnerable parts of the device so it can never hurt to be overly cautious and replace both of them. Unfortunately there's always a cost involved
Let us know how you get on...
Hi the cable is not the only thing that can couse your screen to not respond, ive seen a tp2 that stoped responding because IT captured humidity in the digitizer screen, you can tell if this is the case by mooving your phone under the sun light and you will notice a kind of rainbow loking transparente spot, this humidity causes the digitizer screen to get stuck, the Solution can be to let it dry in the sun, or to rub it jently against your leg, the fricción can help to dry out the humidity, hope IT helps.
Search on here "tp2 screen not responding"
There is a thread on here I found about the screen not responding, and cleaning around the chrome edge with something thin, carefully, (I used my fingernail, which worked, but I lifted the contact too much down by the buttons on the bottom of screen). Worked for me and a few others. Good luck.

Screen Rotation Quirkyness

Anyone notice that the screen doesn't rotate between portrait/lanscape correctly, sometimes it won't at all, if the phone is perpendicular to the ground?
If I tilt the phone closer to the ground, it picks up the orientation correctly (~2 second delay).
Anyone else know what i'm talking about?

If by the phone being perpendicular to the ground you mean parallel to the ground (e.g. screen facing directly up) this sort of behavior is what I'd expect. Because how is the phone supposed to know how you're holding it if it's oriented like it's sitting flat on a table (roughly speaking)?

Exactly. If you were holding it perpendicularly then it would rotate no problem, theoretically.

No no, the phone's screen is parallel to the wall, then if I rotate it 90 degrees, the phone won't rotate the screen, then if I tilt the screen towards the ceiling/floor, the phone picks up and rotates properly.
It seems the OS update I just installed has fixed this behavior.
just like in honeycomb Google added a second or so delay so the phone isn't rotating when you don't want it to.
Although this can be frustrating when you do want it to rotate.
There is and will be more custom roms that remove this delay

yeah i really like it this way i always used to accidently rotate the screen and it irritated me to no end i like that its now more 'deliberate' if you want it to rotate, but i guess its personal preference.
personally the video player should always default to landscape imo usually id keep rotate off but then video player is in landscape :\ least now i can leave rotate on and not be annoyed by it

[Q] Screen remains static when keyboard is slid in

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 .

Quick screen 'taps' register as 'drags' after screen replacement

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.
