Touch Screen has stopped working

Basically about 2 months ago I rooted the phone and put in cyangen mod, everything was fine until the touch screen stopped working. Most of the time it was brief but sometimes the touch screen just wouldn't work for a whole day and then start working again. Thinking I had done the root wrong I unrooted the phone back to it's orginal. However the problem still showed up despite that. I recently updated it to the donut update, and that's when the problem got worse. Now the touch screen won't work and when I go to the contacts using the trackball I get an error. And anytime i recieve a phone call I get the same error. Thinking it was a software problem and factory reset the phone and scaled it back to rc29. But still the touch screen doesn't work, and now because of that I am stuck on the setup screen at the beginning which ask you to touch the android to continue (which I can't). I have wiped and factory reset the g1 many times, and usually that has made the touch screen work again, but now it seems to not work at all. I deducted over the last couple of days that it must be the power adapter causing all of this. Since I got the touch screen working yesterday and had no problems the entire day. Then a hour after I put it on the charger the touch screen stopped working again and hasn't worked since. Is there anything that can be done at this point to fix it? I read somewhere about a script that makes the g1 touch screen work again but haven't been able to find it.

Same problem
I'm having a near identical problem. Most all of the symptoms are the same - except my touchscreen has only worked for a few seconds on one occasion after the initial failure. I've tried wiping, and about 3 different mods (JaCx, Cyan, Enomther). None have helped, and currently I'm stuck at the same point where it's asking me to touch the Android to begin, and I can't. The only difference is that I didn't unroot. So I'm going to try a few more roms, but I doubt I'll have any luck. My phone was also put on a charger that wasn't made for the g1. I began to notice the problem thereafter. Not sure why, but that certainly seems like the only reasonable variable which could be causing this.
Anyone out there have any ideas? It'd be much appreciated.

Have you guys dropped your phone recently? I'd like to share my story as well. Two weeks ago, I dropped the phone on hard tile while it was still in its leather/suade case. I picked it up and instantly found the touch capabilities were gone (with screen open or closed). After many soft resets and not knowing how else to fix it, I also decided to revert back to rc29 from cyanogenmod. Still no go, after being stuck at the setup screen. I disassembled the phone, using the G1 service manual, to make sure none of the ribbons were knocked loose and examined the lcd and digitizer for any cracks. No problems that I could see. Disassembled, and reassembled the phone a few more times and still with no avail.
If you were one of the first to receive a g1, such as myself, oct 22nd is the last day of your 1 yr warranty. So give t-mobile a call, and submit a claim before then if you want to take advantage of it. Make sure you reflash to stock image, and that there are no signs of visible damage on the phone or else the warranty will be void. Good luck.
Edit: If your phone's touch screen is working at random times, I'm suspecting its a hardware problem, most likely a damaged or worn out flex cable from opening and closing the screen. Try slowly opening the screen and touching the screen at the same time to see if anything happens.

When I was waiting for my G1 I came on this forum (Had a Diamond before so knew about it anyway) and found a topic discussing problems like this... If you have an Early G1 then I'm guessing this is the problem...
There is some sort of design flaw with the ribbon cable connecting the Touch Screen to the Mainboard catching onto the sliding mechanism. This eventually destroys the cable and causes the touchscreen to stop working. On Later models they've fixed it by taping the ribbon cable down instead of letting it hang loose.
In short... you need to unroot your phone and take it back to T-Mobile.

Interesting thoughts, thanks for the input. My G1 has never been dropped, and is actually relatively new, only a couple months old. But it's not on T-Mobile. I flashed MLIGN 2.5.7 (Hero). I did this b/c I know it bypasses the typical "touch here" activation BS. So I can boot, and get into the OS just fine. Which is where I'm at now.
Here's what I've done. I completely wiped my Fat32, Ext2, and Linux_Swamp partitions using Gparted. I completely wiped the phone using Cyan 1.4 Recovery. Yet no matter which Mod I use my touch screen doesn't cooperate, AND (no matter which mod I'm using) when I try to launch basic apps (dialer/phone, some settings menus, etc) I am notified that, "android.process.acore" has stopped. Without fail. It ALWAYS does this when attempting to access the dialer/phone. I would be more than happy to take some time troubleshooting the touch screen IF my damn dailer/phone would work. But it does not.
I read on some other forums about there being 2 compcache files for someone who had a similar issue. That's slightly above my head, though, and I'm not quite sure how to go about checking that and/or deleting one. Really, I just want to be able to access my dialer/phone app for the time being. Then I can take some time to trouble shoot the touch screen.
Anyone have any ideas about the process failing, or the compcache affect?
Also, I'm using 1.33.2005 SPL.
Thanks

I realize this is an old thread but did you ever get the issue figured out? My phone did this just last night

Alright as suggested earlier in the thread it was a hardware issue. I found that my touchscreen had become unplugged and was causing the errors.

Sorry to bring this guy back from the dead but I figured I would educate a few people one a common touch-screen problem.
Yeah, 90% of the time it's the adapter you're using. Being a G1 owner with lots of mini-USB chargers i found the same problem. Also being a tech rep at t-mobile, i've had lots of calls revolving around this and fixing it.
The G1 uses a 1000mA charger (1A). For me, the touch-screen going haywire/unresponsive seemed to get more severe as the the chargers specs went lower. An old Motorola charger at 500mA was ridiculous. Talking to customers with the exact symptoms and hardware, eventually lost all functionality of the touch screen.
On a side note, it's not just the G1 that has problems with the wrong charger. A linksys router I have has a standard power port connection type in the back but requires a bigger amp adapter. hooking the wrong one up will cause complete failure. In many situations, not enough energy is just as detrimental as too much energy. One last example: Take a big 10" sub driver, hook it up to a crappy 300W amp, you get an overheated coil and eventually a busted driver.
So, lesson is, just because it fits doesn't mean it's safe to use. I never mix and match adapters with any device ever because of the risk of damage.

[Q] My xperia x1, durbility is poor after just one year of use...

So its been about a year and half since I received this phone for my birthday, and from this moment on, I am 90% sure that these companies design these phones to fall apart after a while so you buy a new one.
Please to not be intimidated by the length of the problems, I really doent want to waste a $600 nice phone. Please help.....
List of problems:
So on one random day, while I was using my phone with EnergyROM sense 6.1 (Not even 6.5 (Windows 6.5.5)) the phone stopped rotating when I flipped the keyboard, as in the screen will not rotate when I try to use the keyboard. The touch screen also becomes uncalibrated, and even when I recalibrate it, it still acts very funky (have to click lower than button or higher, depending on its mood). I did absolutely nothing different with my phone that day, but I did not call my phone dead right away, so I decided to update the ROM with the latest sense 6.5 ROM to see if the OS is corrupt or over-cached. This did not fix the problem.
Also, another very weird thing is the phone's screen will illuminate (I guess backlight), but no picture will show when turned on after sleep mode, and I have to click the top button again to sleep and awake it to get a picture. When flipped, the screen doesn't even fully illuminate, and literally dies down to a black screen (half of the pixels are bright, and then it just fails).
Any help would be very appreciated. What I am thinking of is wiping the phone 100%, and not even leaving a rom on it. I heard there is a command that deletes the junk off your phone from a previous ROM to your updated ROM is clutter free. Any other suggestions?

Edit: I hard reset my phone, and nothing is fixed; I still cannot flip screen into landscape mode.

The "command" you are talking about is called "task 29", look for it in the ROM section.
It sounds like hardware problems, i've had mine for about 1 year and a half as well and no problems besides a couple of scratches.

The flex cable connecting LCD and board might be out of order.... I had the same issue.

Yeah I heard about that problem. I will first task 29 it, but are there any guides to take apart and fix the flex cable, or even just unplugging it and plugging it back in?
Also, what did you do with your broken phone? Did you buy a new one or get it fixed?
Thanks for the feed back both of you.

my X1 also aged same as yours and it still runs flawlessly now. so it might depends on how you used and keep it
as for the "wiping off the phone" its called task 29, and is encouraged to do before you flash a new ROM, have you did it before flashing energyROM?

No, but I just did now, but it seems to be a hardware problem because nothing seems to be working properly still. This is some serious BS because I am very over protected with this phone, just to prevent stuff like this to happen. I have never dropped it ONCE, and it seemed to just wear out by itself. The lenses covering the camera is cracked also, and the screen is all screwed up, and I didnt do absolutely nothing abusive to it, I am 110% sure of this.
Any suggestions on how to fix hardware/ ribbon connected to the screen problem?

Order a new cable and replace it.

If you search on Youtube for the video on how to disassemble x1 there is a complete guide that shows you. Its pretty easy and all you need to do is, take the flex cable out and carefully plug it back in. Then carefully put your X1 back together and hopefully you issue will be fixed. If it still persist, then try and get the flex cable changed.

Auto power-on driving me nuts

Whenever I leave the house, I unplug my Note to take it along but every time, before I stick it in my shirt pocket I have to turn it off first. That's because it on by itself just because I removed the charging cable. At first I thought this would just be a minor annoyance, but by the time I've needlessly turned off the thing a few hundred times the damn thing really starts to annoy me. And it's even worse when I try to charge it in my car because every time I turn the key one way or another I have to turn the phone off yet again. It's a bit more difficult because I have one of those silicon rubber protector things so it takes a little longer to find the off button. But I like the protection that this cover provides. I suppose I could just wait for the timeout (which I like at 5 minutes), but that would waste some battery power that I may need later. Plus it just annoys me if it is on when I'm not using it. (Actually it is the same problem when I plug it in to the charger as well!). So who decided on this ridiculous behavior? If it is an Android thing - shame on Google. If it is a Samsung thing - shame on them. (If so I might even switch phones ... although I haven't heard of another phone that can compete with the Note). Or is it just a quirk of my ROM? (I only used GB for an hour or so, and didn't have time to observe this behavior or not - then I flashed PA which I have been using ever since.) I love this ROM although I would switch in an instant if I could get rid of my only real annoyance with this phone.

First the silicon protector that you put in your phone because it cover also the power when put it in your pocket it keeps triggering it, its like a hair trigger.
Of course when you plug the charger it will trigger the screen to on.
Why dont you just adjust the screen time out to one minute.

I dont have this problem but anyway, a quick fix would be to use Tasker which lets you easily automate everything in your phone

That would result in about as many needless and annoying presses of the power button as it turned off when I didn't want it to.

That would be great if Tasker could turn it off again for me when it was turned on automatically. I took a quick look at the hardware events that tasker can act on such as:
Display: Off/On/Unlocked
File: File Closed/Deleted/Modified/Moved/Opened/Attributes Changed
Hardware: Camera Button, Search Button Long-Press, Card Mounted/Removed/Unmounted
Misc: Gesture, Shake
Phone: Missed Call, Phone Idle/Offhook/Ringing, Received Text, SMS Send Success/Failure
Power: Battery Changed/Full/Low/Overheating
System: Device Boot, Device Shutdown, Device Storage Low, Locale Changed, New/Removed/Updated Package, Wallpaper Changed
However being plugged in or out is not in this list. So how can it be done?
~Paul

I'd like to know too.
I can understand "screen on when charging cable plugged in". But its annoying as hell to have the screen on when charging cable is removed. Since 95% of the time it's going right into my pocket.

press the power button and screen will go of...

let's understand this better:
Your phone is off and turns on upon disconnected from the charger, or it is already on, but you don't want the screen to lighten up when you disconnect?
If it's the first case, that's weird...mine never auto initiates...If the second case, really don't know what you could do.
If it's the first scenario, maybe a factory reset? But beware of the brick bug and flash a safe kernel first.

Hey there Paul,
Man, that is one hell of an issue you have.
Anyway, I don't have much to advice you as I'm not using PA rom on my Note(for the moment ), but hey.. you said it for yourself that you were not able to test it thoroughly your Note before in GB right? only about an hour before flashing to PA?..hmm... logical advice I guess on my end would be to try to flash it back to GB again and observe it for 1 complete day to see if the same issue still occurs.
By the way.. you have a very sensitive Note there bud.
Again, going back to GB is the only way(if you we're to ask me), to confirm if the 'sensitivity' is still there or not anymore.
P.S. I might suggest to you to take out that screen rubber protector in the meantime also. Just use it 'naked' for a day on stock GB.
See how it goes after.
Cheers!

It's the 1st case. My phone is off and charging. I remove the charging cord and the screen just turns on despite the fact that I have not hit the power button - or any button for that matter.
I think it is more weird that you don't have this problem than the fact that I do. I've googled this and found many people complaining about it, but no explanations anywhere why it works this crazy way or how to fix it. And "Noodled24" who responded to my post above is yet one more person who is annoyed by this problem. I suspect there are thousands more (maybe even millions?), most of whom don't vocalize their annoyance.
BTW I'm being pretty glib with my use of the word "off". I'm really just referring to "screen off" - i.e. what happens when you briefly press the power button. I'm aware that this is not really off in the more conventional sense. If I power down using the power button long press, then no ... I don't have any problem with it turning on all by itself. So if this is part of the confusion, sorry about that. In fact, like most phone users, I almost never do a reboot (true power off) unless something goes wrong with the phone.
And recently I've found some people complaining about this problem regarding other Android devices, so I no longer think that this is a problem just with the Note, or just with the particular rom that I am using. Although I still don't know how wide spread the problem is.

I don't think my Note is "sensitive". I've very carefully removed the power cord many times (even without the rubber cover) to be sure that I am not touching the screen or any button whatsoever. And BTW the problem does not happen 90% or 99% or even 99.9% of the time. No - as far as I can tell the problem occurs 100% of the time!. So I wouldn't call my device "sensitive". I would just say that it has been improperly programmed to work in this bizarre fashion. Usually such programming mistakes can be fixed, which of course is why I have posted to this forum.
I don't think going back to GB will solve the problem. I think the same problem happened, although I can't be sure since as I mentioned before I didn't use GB for long before flashing to ICS (PA). However even if it did solve the problem, IMO going that far backwards wouldn't be a very attractive solution.
~Paul

So you don't have to go back to GB......screen turns on when unplugging my stock rooted GB. I think that is the normal behavior.
I agree, unplugging shouldn't turn on the screen, but Google does lots of things that don't make sense in real life usage.

[Q] Any touchscreen issues?

Guys i read on some forums that Mi3 has touch problems like over touch sensitivity and many users are facing it...is there any user here who facing it or it's an hoax? I have ordered one yesterday and i am worried about it..i was fed up of touch on my old phones..please help

I am also experiencing this touchscreen sensitivity issue. Even just hovering my finger on the screen it already responds. Glove mode is off, even tried it while its on, still the same. Did a calibration, no effect. Anyways, it just causes some accidental touches but it does not mess up the entire experience.

its a myth or because of a faulty device.
if it occurs only while charging then it can be the power socket that you are using. (usually occurs if your phone i still plugged in after it has been fully charged. happened on my s3, galaxy s duos and grand duos as well)
could be because of using local charger, faulty battery, basically anything that can mess up the voltage and interfere with the touch screen (but only while charging) very rare chance almost one in a million that somehow a faulty battery causing this.
no such problem on my dad' Mi3 and i ordered it during the first flash sale of Mi3 in India. no issue or problems in the phone so far.

I touch somewhere and it actually gets touched somewhere else.
Using latest stable rom v23 (India) and using stock charger.
What can I do to solve this? Take a replacement of phone or the charger?

you can try different charger and different power socket which will eliminate faulty charger, cable or irregular power supply. if even after testing all this you still have problem better take it to nearest service centre because if its battery's fault let the service centre guys take care of it. don't do anything that may void warranty.

I have tested it with my Note2 stock charger and it still has same issues.
Still will test it out for some days and then decide.
By the way the phone is not one month old so should I take a replacement from flipkart? Or go to a service center?

Go for a replacement. drop an email right now before 30days time period is over. If you are facing this issue only while charging then there is very low chance of it being device fault.

It is a battery fault I think but since the battery is non removable can't do much.

Is your charging point earthed properly.. Mis touch problem is caused due to improper earthing

hum does it have touchscreen problems?
i mean like the ONEPLUSONE?
if so i don't want it. i mean i didnt chois the oneplusone cause off that. my screen has to work 100% fine or i'm going mad

Yes it is earthed properly coz the others phones charge without any issues. I even checked the charger. Its all fine.

I had ghost touch problems when USB charging from my laptop...it was cuz I'm using a third-party charger for my LAPTOP charger...when I remove the laptop from AC power, no ghost touch...
So basically, I doubt there is any problem with the device itself (except for the fact that it is so sensitive to improper charging unlike other devices) but I don't think getting a replacement will help. Just use the supplied charger, on a properly earthed socket.

I had this same touch problem. Actually the problem is that the touch misses. What I mean by that is, draw a straight line from one end to another and in between the touch misses and you get a broken line at many points. I cheked it using the Hardware Test function and going into "Touch screen Test". Start to draw a line and see what happens. It will miss after every 1 sec or so.
So, i tried to find the cause. And i came to know it mostly happened when the phone was put on charging and mostly made the phone unusable while charging. It also occured after taking the phone off the charging if it was overcharged. So I used charger of Samsung Note 3 and voila. The problem is gone.
Summary : Charger supplied with Mi3 is piece of s#it. Dont use it. It will damage the screen with static charge that is left on the screen after charging. Get yourself another good quality charger.

I have noticed this problem. There is touch input even while hovering finger about 3 mm above the screen. I don't mind this problem that much but it does become a minor annoyance sometimes while typing. I don't want to apply for a replacement though as the phone is flawless otherwise and I've heard that even the replacements also have the same problem. I have not yet removed the protective screen cover which comes with the phone so I don't know whether that's causing the issue.
Update: I have applied a tempered glass screen protector and the problem is still present.

I noticed yet another problem. The multi-touch is OK for about 4-5 fingers. But above 5 fingers, the touch gets haywire. Ghost touches, touches not getting registered, touch points swapping, etc start to happen very badly. Is anyone else facing this issue? I tested using antutu benchmark.

Sadly i experience the same issue. The screen gets hypersensitive from time to time. I've had my MI3 only for a week now. Considering doing a factory reset. Any experience?

Go to hardware testing and then to touch sensor and hit menu button and calibrate

My mi3 touchscreen is fully working after 7 months (and i hope even in the future).

Hi,
If you are experiencing serious issues like miss typing and random unwanted button pressing by the phone then this is for you! I recently woke up and found my phone spazing out and not being able slide the screen up properly. So this is what worked for me and hopefully will fix your issues too!
1. Install any updates that need doing. Restart phone.
2. Still have problems then turn off glove mode ( settings and then display) and clear and wipe cache. Do this by holding down the up volume key on the side and power button - wait until the screen goes black and then it should appear in recovery mode. Use volume buttons to select the language and the power button to enter. Go Wipe and Reset and then Wipe Cache. See if that works. If it doesn't please look at Step 3.
3. Now try refiguring and calibrating the touch screen through the hardware menu. This was painful for me as all the buttons i wanted to press hit another key! but eventually got it. Try to key this into the phones key pad and call: *#*#64663#*#*
4. You are now at the hardware menu. Find touch screen and then the black screen appears where you can your finger over and draw. Use the button next the home button to get the start calibration menu ( looks like this 三)
and then hit start calibrating and wait for it to work. I actually need to go into setting to change button layout as only apps appeared when i pressed there....
This then solved all the issues and my phone now works perfectly
Let me know if it worked for you!

Touchscreen Issues

Hi Guys; I recently got my new 2nd Generation Moto G but after setting it up and using it for 20 minutes or so I noticed that sometimes while scrolling through settings, contacts and webpages, that when i am swiping over a horizontal band in the exact center of the screen, the sensitivity of that region of the screen becomes very unreliable and the phone will often interpret scrolling as a press. While scrolling in my phonebook it has a tendancy to call people, when browsing the web it has a tendancy to press links i never wanted it to, and this same behaviour is repeated regardless of what application i am in.
It certainly seems to be more frequent and prominent while I am charging the phone, regardless of the charge current. I have charged it from my pc, 1000ma wall adapter and 850ma wall adapter; all with the same results.
Sometimes turning the screen off and on again can rectify this, but its usualy back again in no time
I have tried factory resetting the phone, with the screen protector both on and off, while on charge and off charge and while making sure nothing else could be interfering with the touch screen i.e., a case.
I only got this phone from ebuyer in the UK 3 days ago, 2 days earlier than it was actually ment to come! so its a real shame im having these problems, I've already spoken to Motorola about it and they have advised me to RMA the phone as they cant give me a definitive answer as to wether or not this is a Hardware or Software issue.
Has anyone else been having issues similar to those that I have experienced with their own new Moto G devices

I would RMA, mine is fine.

Unfortunately my phone displays this behaviour both on and off the charger. It does however display the issue more frequently while on charge.
The chargers I'm using are all 5v which is typical of a phone charger. I have one at 850ma which charges painfully slow, I have another at 1000ma which charges much more quickly. And I use my Computers USB ports to charge at times, no matter how I charge the phone the problem remains.
Sometimes it will work fine for an hour or so then it will go insane on me. I have requested RMA with ebuyer. Had the phone only showed this issue on charge I may have been contempt with it, but the problem can happen anywhere, anytime and for a brand new phone that's not acceptable.
@ xDDen: have you tried charging the phone from any other source besides the Samsung charger you have?

yes now am charging with moto g's charger and it is working fine now without any issues

Mine actually didn't come with a charger. I was a bit surprised, but checking the Amazon page (for Germany, since I bought it here, though not from amazon) reveals that this seems correct/intentional. It did include the usual µUSB cable though (and it's not like I don't have enough USB chargers).
For completeness sake: I don't have the described problem, no matter if plugged in or not...

Touch issue
I'm using Moto G 2014 charger only and still facing issue bringing down notification panel.
Also i face issue when trying to unlock phone via pattern lock.
Flipkart offering me a replacement- Shall i go for it?

Been having a problem with the screen, mainly on the back soft button part of the screen, keep finger on it and it multi presses like a mad thing, doesn't happen all the time though, was driving me crazy. took off the Ultimate Shield screen protector and the problem went away, put the shield back on and the problem didn't come back, then couple of hours later (today) I got the ota update and the screen goes mad again, took shield off again and the problem continued, a few minutes later and it's all fine again. now (a few hours later) still all is fine.
Problem is I was all ready for doing a RMA to Amazon.co.uk for it, stuck on what to do now as if I send it back and they find no fault.

Same issue here, but without any screen protector. OTA update hasn't changed anything. Sometimes it works and sometimes the screen recognizes double/triple taps where it should be only one...

Well the touch screen issues got way too much for me so I returned the phone to Amazon uk and got a refund, bought another moto g from Argos the same day I returned it and I'm glad I did, everything is ok with the new phone, no screen issues at all.

Moto G 2014 Tocuh Screen issues
Same issue here.
Bought phone 1 week ago from Argos. Initially fine, then suddenly cant use the swipe down notification bar.
Turned on the Show Touch indicator in Developer options and it clearly shows that the screen is registering the touches about 0.5cm down the screen from where I am touching. So you can never hit the notification bar when its doing that. I found that turning the screen off with the power button and then back on again usually clears the problem.
In the UK the phone only comes with a USB cable, so I use a variety of chargers.
I think mines going back as not functioning properly

I also having same issue you should post your emei. It might be I purchased defective from one of previous user having same issue. I'm at Singapore.

Me too! I am very sorry to learn that it is a hardware problem.
I'm afraid to take it to the service center because the problem is intermittent and technicians could not detect it .
Any of you have solved?

If it was a hardware problem we could try asking a kind of compensation, I don't know, some free accessories, or maybe the change of the device...

Had a problem with mine, it would go mental pressing the back softkey, press it once and it would just keep doing it by itself, so a problem with lower left of the screen, sent it back to Amazon for refund and got another one from Argos, this one is mostly alright with the screen touches but will sometimes do a double press or think a press is a swipe anywhere on the screen, it's not been so bad that I kept it, but now other problems like the memory shortage making apps close is starting to really get to me, also the screen rotation get stuck in landscape now and then, even it sometimes goes to landscape by itself.
In the process of getting a different phone as this is starting to annoy too much.
