[Q] Digitizer acting fuzzy - G1 Q&A, Help & Troubleshooting

Hello, from some time, the digitizer of my g1 is acting weird, the bottom right part is not sensitive at all, and sometimes the screen gives to the os a completely wrong input, so the screen flicks by itself
Anyone knows what can cause this?
Thanks

well my G1's sensor act different whenever I connect it to (not compatible) charger (i.e. Blackberry's OR Motorola's)
Can't say it's due to fall of your G1 (my G1 fall a hundreds of time & still no problem but just accelerometer got screwed )
It possibly can be cause of you HARD PRESSED that part somehow somewhere .......
OR concern some repairer to get it fixed (i.e. Change digitizer)
Best of Luck

Broken Screen or?

About a month ago I got my Kaiser screen replaced as it was broken, now all of a sudden the screen is all whitish and I can hardly ready whats on it!
Is the screen broken again??
I'm fixing to replace the screen in a Kaiser i bought used with a broken screen. From the reading i've done, it sounds like one of the cables to the screen is loose. Trying pressing on the middle of your keyboard and see if anything happens. The big ribbon cable has a connector there.
hmmmm coming to think of it when I pressed the middle of the screen it used to do some funny effect (like when you press your TFT monitor) but now nothing happens!
Is your screen something like this?

last night i was woken up by a text, i looked at my phone and all of a sudden the screen went crazy. Started scrolling up and down (like a bad signal/wrong format ntsc/pal on a tv). Everything got all messed up and lines and dashes all over, kinda like your screen, it started acting wierder when i began applying pressure on the top of the device by the earpiece and d-pad. So i soft-reset the device and it was still doing it while boot up, leading me to believe it wasn't a software issue.
So in my half awake state i just left it on my nightstand. I woke up and its perfectly fine now, even when i press all around the screen.. wierd huh?
I didn't notice anything like you descriped, touch screen and everything else worked like before. Only the colors were like on the picture. Tried hard reseting but didn't help. Phone is still under warranty so sent it to be repaired, i can post what they did when i get it back.
Thanks jrask. Thats exactly how it looks.
I think i have some bad news for you, the screen was damaged and needed to be replaced. I think it was cracked under the frame.

Screen alignment problem

Hi all,
I recently bought a used X1, wich already had a custom OS (Christian's) installed.
It's an excellent device, though there is one thing that really pisses me off.
The screen alignment is off all the time. No matter how often i re-align, after a short while it always is a few milimeters of, especially on the top half of the screen. So, for example if i want to press a button, i have to press above or under it, else it doesn't work.
I already tried cleaning the edges of the screen, even with pressurized air. Didn't help though.
Is there any solution for this or have i just been ripped off by the seller of this device?
Btw, excuse my english .
Can anyone help me please?
I mean, i really love this phone. But the touchscreen issue makes it kinda useless to me.
Is there any fix for it or is it just the way it is untill i replace the screen?
Hard reset. Or re install the ROM
Make sure to take your time while aligning your device, get some very precise points in or it will throw it all off. If all else fails you can try re-installing, but that probably isn't the problem if realigning fails. Possibly a screen issue?
I hard-resetted (?) and reinstalled the os, didn't work though.
When i re-allign it's all ok, but if i go to 'notes' then, and draw a little, it quickly becomes mis-alligned again.
The line is sometimes drawn more then a centimeter below the stylus :S .
I assume this is not a software problem, perhaps the screen is broken?
Anyway, i'm selling it back to the previous owner...
when i had a problem similar to this it was my ribbon cable that had worn away with sliding the keyboard in and out.

Milestone Touch Screen acting wierd

well when im only using touch keyboard the corners and edges dont work
P,L Backspace, Go, The whole bottom, A, i
Its a common problem. I had the same. Unfortunately your touch screen is dying. Replace.
Sent from my Milestone using XDA App
Welcome to the club, apparently some people fixed it by warming their phone, putting it in rice, or replacing their digitizer.
i have another kind of problem: sometimes the screen begins it's own life, like somebody quickly touching it (solves with on/off button).
And sometimes i touch it in some point, but it thinks, that i touch it in another.
Disappointing, but not annoying.
well it seems to be working fine now

Got the exact same problem, send it for repair. Apparently they found corrosion in my internals, though I really have no idea how liquid got in there. There is no spillage or any sort happen to my phone.
Oh well that means goodbye to my Milestone and back to stone age for awhile.
I had this same problem a week ago, and it happened all day long. It happened that my screen was wet (don't ask me how, I don't know), and now it's working just fine
Well if your touchscreen are not responding well to your touch, or if you feel that a ghost has been playing around on it (eg. "like somebody quickly touching it"), then it's a symptom that the touchscreen is faulty and it's time to replace the digitizer or buy a new phone
I faced the same problem sometime. In this case, reboot the phone may fix this problem.
If it doesn't work, I think you have to replace the touch screen.

Had one issue like this in 3 months, 1/5th from the top of the screen wouldn't respond anymore, no matter the program. The issue went away after rebooting the phone.
I am facing the ghost touch problem or the right side is not working at all. First time, it started on it's own but last night, while it was connected to the PC the nightmare began. I don't know what the heck should I do, because I don't have money to spend on new digitizer. Last time the problem was solved by letting the phone in a dry place (it wasn't dropped in water or so). I hope this time will work too... BTW, pressing the on/off button seems to fix the issues for ~3-4 seconds. Anyway, Moto sucks .

Are you sure this isn't the flex cable problem?
If it is the flex cable problem, where can be found to buy and replace? Because I am sure that is less expensive than replacing the whole digitizer.
I had the same problem, but it's more than a month that I recharge battery with a Samsung wall charger (700mAh power), it completely desappear.
One week ago I charged the battery with the USB cable and the problem reappear, desappearing only after a reboot.
It's NOT a flex problem for sure, our phone is very susceptible of current variations when charging. If the problem still remains after unplug and reboot, I suggest to try with another battery.

[Q] Repairing/assembling G1 -> broken volume rocker and touch panel

Well, I fixed my old broken G1 with new screen, touchscreen panel, case and keyboard.
Now I have 2 issue:
1) Sometimes my touchscreen goes grazy!! If I use the touch test application I see that sometimes when I touch the screen in an area there is another virtual touch in another zone of the screen. I read that it can depend from the current source when I charge the phone.. but I'm going crazy!! I opened my phone 10 times (I thought there was a problem in the cable that link TouchPanel to LCDPanel, because when I lock the cable with the clip it tends anyway to go out from the connector, now I put some scotch tape to fix but the problem is here.. so I think is another problem).
2) My volume rocker doesn't work!!
I bought 2 new keyboard to fix this problem, but no one of that fixed the problem. I thought the first new keyboard had volume keys broken, so I bought another one, but the problem persists!!
Now the Touch problem rarely happens, but the volume rocker is completely unusable..
Someone have experience about G1 assembling/repairing ?
Thanks and sorry for bad english
if you have put in multiple keypads have the same issue i would assume that it is the connection going to the motherboard. just a guess there but its either that or you have had a bunch of faulty keyboards.
only other thing would be a software problem
does the keypad work in recovery (let you go up down throughout the list) ?
as for the touch screen, probably need a new digitizer or flex cable, both are cheap and it sounds like you have the knowhow to replace them.
Ok, but digitizer is new!! screen also is new, and I have bought a total of 4 flex cable because I see that they are fragile (I broke the first I bought).
I tried to change flex cable but the problem remain the same.
The only thing that can be damaged is the LCD cable that links to the flex cable: it has a small cut where the cable have a curve, but the cut don't reaches the contacts (the cable is transparent). I also use some glue and scotch tape to mantein lock the cable.
The digitizer cable is connected to the LCD cable, and then they go to the flex cable that connect them to the motherboard.
The strange thing is that seems a software issue, because if I turn off and than turn on the screen, the problem is fixed for some seconds, minutes and sometimes hours...
Another strange thing is the possibility to control the screen with some metal objects from the moment that the virtual touch problem appear (I can control the screen also without touch it, with hand and piece of metal)
video:
have you tried a factory reset if you think it may be a software issue? if that dosent work you can try install a whole new rom.
really it sounds like it isnt the hardware since you appear to know what youre doing. i have a had a few phones that had screen (digitizer) issues and a new rom flashed cured it just fine
since you dont mind putting a few dollars into it, and your familiar with the inside, you can always try to pick up a cheap motherboard or spare phone from ebay or what have you, then swap the motherboard and you could then hopefully find out if it is the hardware or software

Huh sounds like you got a cheap digitizer than. Most good digitizers use heat to touch. If it's literally touch, then sounds like its a fake/meh digitizer. i hate the digitizers that aren't heat, but press. I see them all the time in those first samsuck touchscreen phones. And they usually die in a bit. I had a Samsung behold with a screwed up digitizer

Yes I flashed 3 or 4 roms after a wipe (I tried also super-wipe.zip), but the problem is here..
The digitizer works well some times, but sometimes get crazy (you can see in the video).
I don't that my new digitizer is fake, but I really don't know!
BTW I'm trying to repair my phone for fun (now I have desire z) and because I am fascinated by my old G1.
PS:
I see another strange issue--
If I touch the screen when the phone is on a table the screen digitizer is not very sensitive and can't take input from fingertips.
If I touch the screen when the phone is in my other hand, the screen digitizer is a lot more sensitive and it take input from fingertips.
My impression is that there is an electric field or something similar that disturbs the digitizer, and when I take the phone in my hand I discharge that field to ground. Also when I turn off the screen, seems that the electric field discharge so when I turn on the screen is ok, but after some seconds the field returns to disturbs the screen.
I really don't know, but is the impression that I have.. something that is not shielded.
Now I'll try to use my phone in airplain mode.
Thanks guys, I'm happy to see that this forum is still very active

Screen going crazy!

Hey guys.
Lately, my screen has being going insane. Switching between panels, clicking on stuff, lowering the notification bar all on it's own while not responding to my touch input at all!
Weird thing is it happens a couple of seconds after I turn on my screen. So for a few seconds it's fine.
Is there a way to fix that? Maybe the digitizer has either gone kaput or is just dirty?
The digitizer is either broken or there's too much moisture inside.
This topic has been discussed hundreds of times already - look it up please.
Same thing happened to mine... I jus changed the digitizer... I but broke my phone in the process

Digitizer Problem
Yeah, you just have to change the digitizer. This happened to me twice on the milestone. You could send it for repair, and i do not think it would cost much if its only the digitizer.
Do I need to take the whole phone apart to get the digitizer or is there a way to unscrew the screen directly?
The entire phone must be disassembled to reach the digitizer. The only problem is that sometimes it's not the digitizer that's faulty, but the flex cable, that becomes used in time. So, I suggest you to open it and see if there are any signs of degradation (it's a black ribbon that holds the sensors and the phone calls speaker). If there are, I suggest you to replace that, and not the digitizer itself.
