Frozen G1...Kinda

Hey all, long time reader first time poster regarding troubleshooting. I searched the site and couldn't locate anything regarding this, so I apologize if I fail at research. I have a T-Mobile G1, and the phone very oddly is running perfectly when the keyboard has been exposed but once closed the phone freezes. No touchscreen movement, trackball, camera button, ect; only the power button idles the screen to black. Now at first I got worried but I flipped the keyboard out and it functions perfectly again. I rebooted phone and it is the same case, the G1 start up and rom loading screen will remain frozen unless I slide open keyboard.
Is this a motherboard error? Seeing the touchscreen functions when open I eliminated that, but has this happened to anyone else? Thanks, and sorry for wall of text.

Boot into recovery and see if the trackball works in there. If it does, then its simply a firmware issue and a full wipe should fix it. If it's not, then you probably dropped the phone or something and there is probably some sort of cable disconected/brocken inside the phone.

I completed a full wipe and am experiencing the same problems. I take very good care with my phone and was dropped once months back by someone bumping into me. Would it be possible for myself to self serve the phone and make sure all wires are secure? Or is it possibly anything else?

I have the same issue I've taken the phone apart along with many other G1s and have never seen this problem. I used this phone for almost 6 months lent it to a friend for a week and now it does this. So my guess is it's the flex cable between the screen and keyboard or would it have to do with the motherboard do you think?
I'm taking it apart as we speak I'll post what I find.

Did you have any luck, PlatinumMOTO?

[Q] Touch screen dead spots

This may be a problem beyond the scope of android, but seeing as I'm running it, I thought I'd try here first.
I've noticed that the lower left hand side of my screen has a "dead spot" where touch is simply not registered. To illustrate, I went to screen calibration's test screen and drew a straight line along the edge of the screen. (See Attachment)
I've tried recalibrating the screen (manually and resetting to default calibration) as well as wiping data and reinstalling the system. Reinstalling the system worked once, but then the problem came back and subsequent reinstalls did not fix the issue.
I'm running Incubus26jc super froyo [RLS 12] on the 15-07-10 340X480 Froyo Kernel.
Anyone else seen anything like this? As far as I can tell, the problem is not getting any worse. Currently, it's only a hindrance when trying to use keys in that region, but I can work around it by switching to and from landscape. It's a bit of a hassle, so I'm hoping someone may be able to shed some light on the situation.
I was sure it was hardware until the system reinstall fixed it, but am now baffled as I can no longer replicate the fix.
I have not tried reinstalling the kernel but will at some point in the next day or so. I'd like to avoid switching back to WM to check if the problem persists, but may have to... we'll see. Doing everything I can to make this phone last until the Incredible month of February when I'm up for an upgrade.

dont know the issue resolution... but i have the same with my touch vogue.. and in the same 'area' apparently as well.
hard for me to hit the 'a' key on my keyboard. hehe

I'm glad to see I'm not the only one... anyone else?

Bottom right corner for me... I was able to calibrate around it but it took a few tries.

The sensitivity across my screen was inconsistent some time ago. I found that years of my abuse had taken a tole on the exterior of my phone. It eventually got worse and I bought a new housing (with a new digitizer) on ebay for a reasonable price. If it is hardware then it really isn't that hard to fix if you like taking things apart.
If you're sure that win mo accepts input from that part of the screen then nevermind my post. I would play with a painting app though and investigate the hardware further.
I may be talking a little out my a$$ with this part but.. is it possible that in calibrating your screen the os may change it's settings on how hard you have to press and such also. that may be how you got it working.
In any case, my investment in a hew housing was well worth it considering how modern my old phone has become thanks to the developers here.

In my case, no - when drawing a straight line down or across the screen, the line starts 'moving' away from the stylus (like the picture in the OP).

Gah... now it's shutting itself off randomly and the dead spot has grown. Not good at all.

Yeah, mine was better for a while then 'slid' again. I ended up swapping the digitizer with my other Vogue and things are back to normal.
Sent from my Full Android on Vogue using XDA App

I have another vogue, but am weary of doing anything like that. How hard was it to get done?

All you need to do is switch the front half of the housing rather than the digitizer itself- it's not hard. There's a teardown guide somewhere in the forum, Google Vogue teardown and it should be at the top.
Sent from my Full Android on Vogue using XDA App

The only thing that worries me is that my spare vogue exists because it was dropped in a muddy puddle. I'm hoping the water damage isn't too bad. Guess we'll just have to see.

it is really annoying
I have the exact same problem and I too thought it was a hardware issue till I saw this Thread. I was ignoring it till two days ago when it started really bugging me. Now, I don't even need to press any button and it automatically gets pressed around the curve and I have a google search box there, so it keeps on searching for eee or sss randomly and started draining my battery. Is there a proper fix for this?

I thought I'd chime in too... I could never seem to calibrate the touchscreen properly in either Android or Debian. Changing the screen resolution (i.e. msmfb scaling) seems to have no effect, whether it's 240x320 or 640x480. Any area within 5mm or so of the edges of the LCD will register as the edge, making "A" and several other keys on the virtual keyboard impossible to hit. Passing calibration values to the kernel didn't seem to fix anything, but it's possible I was using them the wrong way...

i have the same kind of problem on my Kaiser... i think its realted to hardware... either the housing or the digitizer...

I am experiencing the same problem on X10 mini pro. the same screen spot exactly, i have to try very hard to get z or x or shift to work. Sometimes when I try locking the screen and unlocking it back, it works.

update
so after a very long time with this problem i decided to change the digitizer and problem is gonne. visualy the broken digitizer had nothing wrong with it. The fix was fairly easy though, there is no glued parts involved into getting a new digitizer on the u20i.

Touch Screen
I just bought a brand new Cubot One and it looks more than perfect! It has just a little problem with the touch screen ( I think its the software, need ROM change). There is a dead line on the right side of the screen that touch doesn't work at all. Any solutions? Anyone faced that before? Can I fix it myself or do I have to send it back for replacement? Is there any video or guide that shows its done?
I uploaded a video on YouTube to show the problem but i cant post it yet.. (new member)
You can write "Cubot One touch screen problem" and it's the 1st one.
Thank You!

Touch screen responsiveness issue

Hi there,
I'm having a problem with my touch screen. It works fine most of the time, except, when I tap the same area many times very quickly (like when I'm backspacing a whole message), that par of the touch screen eventually becomes unresponsive. It becomes responsive again once I turn the screen lock on and off again (the top button). I've read a few threads around with very similar problems (not on here I don't think).
I replaced the touch screen a week ago, but I've only noticed this today, so I'm not sure whether or not it's related.
I'm just running standard LG software and haven't put any third party stuff on there (apart from apps). I've done a full reset using the update utility, and using the hidden menu, but this did not fix the problem.
Here's some details about my phone:
Model: LG-P970
Android Version: 2.3.4
Kernel Version: 2.6.35
Build Number: GRJ22
Software Version: LG-P970-V20C
Please let me know if I should provide any more information. I'm just interested in knowing whether it's a problem with the touch screen, or the phone's software.
Also, I'm new to forums and what-not, so if I'm doing anything wrong, let me know!.
Ok, I've realised this is in the wrong category. Was bound to have done something wrong - won't happen again!
Thanks

Hi there,
Tell me please, does the same happen on the touch keys (menu, home, back, search)?
Also, do you have any screen protector applied?

I have said this few times in other posts..iIts a strange bug, like the touch being lost.
Its fixed easy by locking the phone, thus shutting down the screeen and touch sensor. After few seconds unlock the phone and check if it is solved, or do the process again.

Thanks
Hi Guys,
Thanks for the replies, sorry I've been away for a while.
It doesn't tend to happen on the home, back, etc, keys. It tends to happen mostly near where the backspace key on the keyboard is. It happens in other places, but it takes a lot more to trigger it to happen in the other places. (by trigger, I mean if you tap the same spot heaps when writing a message it starts to happen).
Also, yes, I've applied a screen protector. The screen protector got put on about 10 hours after the new screen, but I can't for the life of me remember whether or not it was doing it without the screen protector.
Yes, locking and unlocking the phone does fix the problem, but it's a bit of a pain doing this a few times when writing a long message.
I'd really like to know if anyone can tell me whether replacing the touchscreen will solve the problem, or if its to do with other hardware/software. I've since started using the CM roms and it's still an issue.
Cheers.

I have a touch-screen problem with my LG P970 (CM-10 stable)
Hi,
I have been using my lg p970 for more than 2 yrs however when I installed cm10 stable i my phone it works fine for some time then touch-screen does not response properly. When I touch in one corner response comes from other corner, especially while typing when I press one key 2-3 other keys are also pressed even though the keys which are press not even close to each other. I have install another keyboard from market this has reduce some misbehavior.
Please any one has a 100% solution to this problem please reply.
Thank You.

For me it is rom related...

My main reason for reverting back to 2.3.4. Usually occurred when receiving a call; I couldn't answer or reboot the phone. I had to pull the battery every time.
I'm not aware of any fix, save reverting back to a GB ROM.

i think its hardware issue,,if i press and hold a little while on upper screen (right beside lg logo) touch screen became normal again. but sometimes need to hold on there when touch not work again. a member on this forum call it a flex issue of the touchscreen.
anyone know how much cost to replace it with new flex to fix this issue?

If it works with 2.3.4 and not other versions, it's a ROM issue. Changing the screens probably won't help.
This loss of touch was reported by many users, and it's always a 4.0.4+ problem. Something software-wise is crashing, or there's a driver bug.

[POOL] About the touchscreen problem

I only discovered the touchscreen issue yesterday doing the test of the other thread. So, i would like to every z1 owner to answer this pool to know how bad things are and if we can try to find a solution, since i think Sony won't.
So, please answer the poll and post any useful information. I'll start.
My phone model is C6943, I currently don't use case and I'm using a screen protection. I can do the xperia touchscreen test without touching the phone body without problem and also doesn't have problem with pattern password.

Pool? I think you mean "poll"
My 6902 is completely screwed. At first I used a screen protector and the problem wasn't too bad. Then I removed it when I took the phone in to get another issue fixed and soon after that the problem got very bad. I was traveling so couldn't go back to the service center. Now it's a bit better, randomly works and randomly doesn't. When I was home in cold weather though it seemed a lot worse than it is now that I'm back in India where it's warm. Not sure if temperature is a factor, or could be conscience. But a few weeks ago it was so bad you couldn't type even a two letter word using Swype.
Also, I now have a part of my screen in the form of a horizontal line where touch doesn't work at all. No single touch and no drag. Completely dead. Taking it to the service center soon.

You should vote on the first option, then

Guys, check my post "News from whats is causing touch screen problem" to see if is your case!

It's not.
I got problem unlocking with patterns, scrolling pages and when I play some games after few minutes it stop working so I voted the first option. My phone is back to Sony, I hope they know what to do and at last it's Made in China.

Please, post if you use case and screen protections too. This could help understanding the problem.

Additional data : Z1 is being handled in a leather case, back and screen protector removed ( not the one with the logo, the plastic ones that makes your camera blurry )
Touchscreen problem seen in the game Alien Shooter, after some playing, the touch screen becomes less and less responsive ( i tap a button to shoot and use some onscreen joystick to move ) - both become unresponsive/less responsive as you play and the phone gathers some heat ( you can feel the touchscreen becoming hotter )

i have a simple tpu case, i had a bit of problem when playing all touch-based games (not ones with gyro like asphalt).
ever since i got the case it's better, i have the ASF and nillkin matte screen protector

I did not use any case just a chip screen protector. Anyway on a good healthy touch screen the screen protector should not influence the touch screen respond.

Hey guys, I have also this touchscreen issue, and I would appreciate if you give a feedback about warranty service, if sony accepted the problem and replaced a touchpanel or not, and also if the replaced touchscreen is better or not. I´m also thinking about sending it back for warranty repair.
I have also found that my phones touch screen is temperature sensitive, when it get cold or warm it just refuses to detect touch actions. Try it yourself put the phone into cold/hot water for 5 second, take it out, quickly clean the display from water and test the touchscreen. I first tought this behavior is normal and I didn´t cared until I started to play games. After 15minutes of playing the touchscreen bug every time appears. But also after a while its randomly disappears. So this thing is strange. (the bug appears identically also when I have my phone in a plastic case)

For me the warranty worked perfectly, i changed the phone 3 times until get a working one, i called Sony, discribed my problem and they changed for me, only 2 days for the change. BUT i recorded the problem and sent to them, so they accept the change.

Same here. I sent my phone back last week to the store where I bought it 2 months ago. They will send the phone to Sony Center but the time for repair or replace the device will not be 2 or 3 days but from 2 weeks to no eta. When the phone will come back to the store they will send the phone to me. I will post if the problem persist or not.

The problem is if they return a phone with the same problem.

They should be aware about this issue even on the new device so at this time they probably will check that but if they return a phone with the same problem, I will send it back again like many did. Someone had to replace the phone 3 times and I will do the same.

IYeah, you will be a long time without your phone though. I think I'll wait a bit since i rarely get the error and actually only when i try to reproduce it. How bad was yours?

I was able to reproduce the problem in many ways, Touch Screen Test, Opening the phone with Patterns, Scrolling Pages or with Launcher instead of switch the page it was opening the applications and at last when I was gaming at one point the touch stopped working and I had to wait, so this made my mind to send it back. On daily use was all ok but in some circumstances was frustrating.

i had the problem with cm11. and when I retored to stock then the problem was gone:S

I'm on stock and I got the problem.
Today for the first time I got the problem when writing on handrite. So I thought about using my phone warranty to get anotehr one. But it don't always fails when i do the method to reproduce it. So, how do you test if your new phone is working and how do you prove that it isn't? I mean what if i take the phone to warranty and it works?
And for you who already changed phone, it is working?

[Q] Touch malfunction

Hello lovely people of XDA.
Both my wife and me have the Z1, i for my part have experienced screen self cracking and now she is experiencing touch malfunction.
It acts out from time to time, making typing a pain in the a** and playing games even more dificult.
F.ex. if she presses the F key, it registers the D etc.
Ive made a video of this availible here:
http://youtu.be/McGnrGfVpq8 (Sorry about the music, but there was too mutch background noise).
This happens on the home screen, during Candy Crush(yeah i know) and during texting.
Ive repaired the phone twice(previous and newest firmware) via Sony PC Software and still its no good.
It even acted out on the first boot.
Has anyone ever seen anything like this?
Can't seem too find any solution.

Theres a well documented thread about touchscreen issues, I myself was one of the people it affected, your problem sounds slightly different.
The method to test was put the phone on a flat surface and make contact with the screen, move around and if you notice a break in contact then you more than likely have the bug.
Holding the metal frame of the phone in your hand eradicated the issue for some (me included) but it was certainly a pain.
My problem went away on it's own but some weren't so lucky.
Have a search for the thread in here, it's more than likely still active.
If nothing helps from that thread then it's more than likely a case of doing a warranty repair. (if it's the same issue)

Hello there and thank you for your reply.
As it seems to me there has been no solution to the problem, ive tried holding the phone without a case and the problem persist.
People are talking about the new update fixing it, but ive tried both updating and reseting the phone so that did not do anything.
It seems like the only thing to do is to send it in for a warranty repair.
With my self cracking the workshop told me that some of the frames where faulty placed in the factory and therefore might crack the screen after a long time under pressure.
Perhaps this is related somehow, though it feels and looks like a software bug.
Thank you for your reply, i'll be sure to keep a look out on that thread. (i found it now, but i could not find it before i posted this :S)
Thanks again

The kitkat update was rumored to remedy these touch screen issues. Have you updated? My C6906 was giving me occasional touch screen issues but they are non-existent after updating.
Sent from my C6906 using XDA Premium 4 mobile app

Yes i have installed Kit Kat, seemed to help at first but started acting out again the same day.
I even did a factory reset with newest firmware downloaded through PC Companion.
I'll keep looking around and post my findings.(If any)
Update:
So we both sent our phones to the service center and sold them right afterwards. Could not find a solution for the problem and the service center ended up replacing my handset and my wifes screen.
I now have a Nexus 6(it's so fantastic!) and she has an iPhone6 plus(Blaaarh...)...
