[Q] G2 Screen Issues

Hello,
I've been having touch screen issues lately, since i rooted and switched to CM 6.1 a couple of weeks ago. The screen will work perfectly for a little while, but will inevitably stop responding. I'm using launcherpro, though i don't believe that's the issue- it happens regardless of which launcher I'm running (I've tried others and experienced the same issue. The optical scroll pad will still "sort of" work- better than the screen (which will respond to the occasional touch after the problem begins, but barely does). If I reboot, the problem will usually go away for a while again, but will recur. I wind up needing to fix the issue once or twice a day. I don't think it's a hardware problem because the reset fixes it, so I assume it is then software. Also, i don't remember having this problem with the stock rom. Has anyone else experienced this, or does anyone have any ideas?
Thanks!

Dunno how useful this will be, but have you tried reflashing CM?

Same problem here. But I've noticed sometimes if I'm using the phone not in my hand (on car dock or just on table) this problem seems to happen more...but when I hold it in my palm then works fine.
But sometimes it just becomes unresponsive. Am running virtous's rom on my g2. But I can remember having the same issue when running cm on my g1 days too. Reboot always fixed it, just gets annoying.
Anyone have fixes to this? Thanks!!

I personally use GV 7 or sparksmod and. Never had a problem, these are the best roms I think for this phone.

Been having this exact problem for weeks now. And I believe it is a hardware problem, probably some sort of short in one of the ribbon cables or the digitizer itself. Occasionally, actually 85% of the time I'd try to open an apparently and the phone would act if I held my finger down and then the apparently icon gets selected...very annoying cus it happens over and over a couple times, all I can do is keep trying until it does what its supposed to. Also with the on screen keyboard when I'm texting it'll act like I'm holding down on one of the letters and keeps bringing up the special characters to that letter...or ill tap delete to delete a spelling error and it'll end up holding it down and deleting my whole damn text and I can't stop it.
At first when this first started happening I could simply tap the screen and it would stop the crap it was doing and work fine. As time went on I noticed I kept having to hit it harder and harder for it to correct it. Wellllll guess what? Last night it was acting up horribly and I slammed my closed hand against it while it was on the desk and it cracked the LCD screen and now the phone is completely useless, even though the outer touchscreen is perfectly fine.
The restarting of the phone also usually fixed it for me as well but only for a few minutes.. which also makes me think its a short because after the phone is turned off whatever part is shorting out, that circuit is closed and just takes time until you press on the screen in whatever spot to cause the two parts to touch and create the short all over again.
Anyways that's my story...just don't get angry and slam down on the screen lol. This is my 2nd G2 and I'm tired of it, probably just going to get a nexus s or just go back to the nexus one, atleast it was reliable.

if you open the battery cover u can see that there are connectors that closes the whole circuit, so when u are holding the phone the back cover works like a grounding area that makes the screen responce to your touch. Acapacitive screen works like this: when you touch in any area on the screen, you simply are breaking the electrical field that the screen has, the screen "feels" where u break it and tells the operating system.
the electrical field depends on the human body a bit to make the circuit complete, so when u touch the metal parts of the phone, the screen works like it is designed.

i am barely/not getting any service with my new nexus one

i just opened it up and it barely gets a connection or no connection at all. sometimes it says its connected to 3g and when i open the browser it says i have no data connection. i have no clue what's going on.
so far i've gotten a new sim card and i typed in *#*#4636#*# trying to reset the radio but neither seemed to help. i don't know what it can be. i thought this was all fixed with gingerbread. i have 7 days from today to return it to the seller (ebay) but i'm hoping to fix it myself.
does anyone have some pointers that may help me? i've done searches and that's where i got the idea to get a new sim and type *#*#4636#*# but that's all i could find here. anyone have another solution that i don't know about?
EDIT: i just called t-mobile and forgot that they don't support the phone and htc closed an hour ago. i really don't want a refurbished phone after getting it new. i guess i should get into contact with the seller if htc isn't able to help me fix the problem.

Is all 3G settings right ?

how so? i'm pretty certain they are. i say i barely/not getting any service is because for about a minute or two i was able to sync my gmail account with the phone but since then i haven't been able to get online.

Is your hand covering the bottom of the phone, on the back, blocking the antenna? Test by setting the phone on the table and see if signal gets better.

Wait, the antenna for the Nexus is on the bottom of the phone and not the top?

Yes the bottom plastic cover, and its very sensitive to your hand so in low signal areas leave it exposed to avoid signal attenuation.

Do you have the right apn settings? Is it the t-mo version of the n1?

it's the t-mobile version of the phone. i called htc and they said it's probably a bad antenna. i emailed the buyer and will be sending it back for an exchange.

Brand new n1? Next time just get it from Google's developers site or hit up craigslist as the buyers will let you try the phone out right on the spot.

Can this G2 be saved?

My phone seems to be working fine, but it is hard to tell since the screen usually won't turn on. I say usually because once or twice a day I can wake the phone up and the screen will work, but as soon as the screen turns off again it usually won't come back on.
I am wondering if I wipe the phone back to stock if that might make it work like normal again, but my question to you is, Can I restore the phone to its original state without using the screen? Every time I try to boot to recovery or bootloader the screen stops working and I am stuck. Can I use ADB to do everything? If so, I need to know the commands to type in.

Is your ribbon cable loose?

My phone also has a problem that sometimes appears.
Sometimes, the screen won't turn on at all. I would use the phone normally and lock the screen. Then, all of the sudden, when I pick it up again it wouldn't turn on at all, it's like it shut down.. After pressing the POWER button, it reboots and then works.

I am still thinking this is a software glitch rather than a hardware problem. The screen came on the first try this morning and I went into Our Groceries to add something. When I backed out of it the screen turned off, and hasn't come on since. Also, last night it was also working and I went into settings to lower the screen brightness. No matter what I set it to it stayed the same, and the Auto setting was unchecked. I think I need to just reflash the rom but I don't know how to do that without the screen being on.

Some phones have problems handling low voltages in sleep mode if you have underclocked it. On one of my g2's i had to 384mhz or something like that for the screen to turn on.
I think it was the underclocking, not shure. But something with the screen voltage

If all else fails, flash it to a stock rom. Try to make sure all the overclocking features are turned off. Try finding a rom that's just a clean and rooted stock rom. Do that first, then if that doesn't work then flash to stock.
Remember overclocking isn't for every chip on every phone. Not all chips are made equal, and some can be amazing at overclocking or under volting and some not at all.

That is what I am wanting to do, but how do I do that without being able to see the screen? Every time I boot into recovery, or even bootloader, I have no screen to see what I am doing.

If you can't see the screen even in recovery then it must be hardware. You might have damaged the flex cable to the LCD+digitizer. You can try to flash it to stock with HTC's tools. I remember doing it to my phone without needing to touch it at all. So long as the phone is on and charged, you should be able to do it. Just do a quick search on the forums, but make sure not to flash a rom that you can't root.
You can get it on Ebay for $26. They sell them with tools for a bit more if you don't have the tools.

Wow. So the cable is actually user replaceable? I guess I need a YouTube video or something to show how it's done. Of course, my screen works SOME of the time, so I don't know if I have the guts to perform this type of surgery without a viable backup plan if something goes wrong. This looks like something I would try after I have a suitable replacement phone already. Still, I find it impressive that this part is so easy to find! Thanks for the links!

If you decide to replace the ribbon, go ahead and replace the hinge spring as well, worked wonders for my G2.

i replaced the screen ribbon and the spring at the same time.
it wasn't too hard. takes about 15 - 20 minutes to do it the first time.
you can buy the entire ribbon assembly for pretty cheap. just be VERY careful with the USB/SD card ribbons on the side of the main board. one is a clip, the other is a pull tab. if u dont know which one is which- the phone will not have SD card capability when you break them :-(

This is the dirty secret of smart phones, in that nearly everything is replaceable, and usually for cheap.
Damaged the phone physically = housing = $60
damaged screen = lcd + digitizer = $50
Even the speakers are like $3, and I know cause I had to replace mine. The only thing that'll make you want to throw the phone away is if the main board or logic board is damaged. Even then you could probably find a broken phone that at least has a working board for cheap. I actually bought a $15 broken G2 that I plan to repair and give it to my sister as a gift. I have enough spare parts to make it work.
As for changing it, there's plenty of guides on how to replace the digitizer on YouTube. You have to replace the cable to get to the lcd+digitizer, so just follow the video up to that point.

I just wanted to say Thank You to everyone who helped me on this. I bought the ribbon, watched the YouTube video, and now I have a working phone again! $25 sure beats $350 for a new phone, and it was more fun , too.
Now my screen has trouble displaying colors with gradients. It looks like it isn't showing all the colors, so there is a weird muddy area between the dark and lighter portions, sort of like playing an old Sierra computer game from the 80's. Did it revert to only showing 65k colors instead of millions? Still, not a deal breaker in any way. The phone works and i couldn't be happier!

Touchscreen Controlling Itself

I picked up my Nexus 7 about a half hour ago, woke it up and all of the sudden it started clicking things on its own. I wasn't even touching the screen at all. I had to lock the device for it to stop doing it, and after waking it back up the touchscreen was twonky. I would touch, but it wouldn't register until like the 3rd click. I restarted the device and its fine again.
I have the screen separation issue, though its not bad and doesnt bother me so I havent considered sending it back. But now that it has a mind of its own, its kind of freaking me out. I am unable to replicate it so far and I can't find anybody on these forums who has the same problem. Any ideas what is going on?

I had the same thing happen to me a couple weeks ago.
After waking it up from sleep it started touching itself.
I restarted the device and it hasn't happened since.
Hope I don't have to return it.

I had the same thing happen on Saturday. There were odd solid white line outlines around the icons as well. I had to force it to power off and restart it. It's been okay since.

I too experienced the issue. I can replicate the issue by running "Gallery" app, select an album, set it on Slide Show mode. Within 15 mins or so, it will start malfunctioning.

I've discovered how to reproduce the problem on my tablet:
1. Put the tablet to sleep by closing smart cover or using a magnet
2. Plug in wall charger
3. Open the smart cover and the touchscreen malfunctions
The screen does not malfunction when I put the device to sleep by pressing the power button and insert the charger.
Can anyone else confirm this happens to them or is it just me?

My nexus7 is controlling itself after 10 mins of playing a game... this is nuts?
EDIT:
Really PI$$ED off now. Travelled to the shop where I bought it. Told them they said "they have to see the problem" I sit there for 25 minutes playing a game, google earth...anything to create this problem.
NOTHING.
get back home!! gusss what? stupid tablet is controlling itself again! OMG this crap is annoying.
edit: I sold the nexus. It had a fault on the screen. I paid £70 and managed to get £80 for it so am happy with that at least

Same issue!! Is someone remotely hacking in??
I have seen the exact same issue on mine. Weird and very worrying. Have seen apps being opened and pages being scrolled. Has only happened twice in the past few weeks (that I have noticed). Have checked firewall logs on my home network, but unfortunately my ISP has made the UI more 'user friendly' even in advance mode so can't get any actually useful information from the logs (though I don't have any port forwarding active). My only guess is that it is therefore:
A) Random HW/SW issue - seems unlikely, but possible I guess
B) Some nefarious app giving external access (all apps from Play Store though)
Will try and get a video of it next time to put on Youtube nad have installed the logcat app (though to be honest I don't really know how to use it).
Anyone else seen this or have any suggestions on what to do?

May I ask. Have you used a case that has a magnet that may have touched the screen? I theorized that this may have happened to mine because right where the magnet clipped the case is right where fault started. When i touched the screen just on the edge in that spot it started going crazy.
So I sold as faulty

Hi - I have briefly (only use it when travelling and have it in a bag to protect it from knocks and scrapes), but the case was never around when the screen has been off doing it's own thing....so I would be surprised if there was a link between a small magnet being near it a few times and a recurrent fault of some kind.

I read somebody else used a case with a magnet and thought that slight chance that it could've caused the fault. I know on the one I had I could instantly recreate the problem by touching in that place a few times. perhaps just a coincidence?

My device has a similar issue randomly. Detects inputs that aren't there. Most of the time it is one prolonged input. Sleep then wake and problem solved. I don't know if I have the screen seperation issue or not. My device is only two weeks old and has never seen a magnet before.

Bought 4 Nexus 7's for the family for Christmas and one unit had this issue. Read up about it before returning it the next day. Apparently it's a problem with the digitizer (I think that was what the hardware piece was called). Basically made the N7 unusable because it'd detect other "ghost" touches. Especially annoying when trying to unlock the device. Long story short, the unit was returned to Staples and replaced with a new one. So if you're is still under the "new buy" warranty I'd definitely try for a replacement.

Ditto, + 1 here and my ex-N7 16GB WiFi unit was from local Staples, 1 of 2 "open-box" ones that they had in stock, no wonder manager was "kind" enough to approve a 10% discount for it, hmmm - SOB quite possibly knew it was a problem unit returned by another customer & just wanted to pass it on. It had 4.1.2 loaded and intially, the OTA upgrade to 4.2 seemed to make things better (false.)
It was horrible with the sluggish & un-responsive touchscreen and even unlocking, especially bad over time as I had managed to unlock the bootloader & root it to load custom Rom. It's as if the hardware had a keylogger installed and/or was hacked remotely, trying to take over the tablet and typing its own command as I input gmail account info & password - freaking mad crazy, to the point as others said, I started checking the wireless router's firewall & security logs, etc. for signs of breach, etc. and even release the DHCP to get a new external IP on our Fios link. Disabling WiFi seemed to at least "calm" it down but made the device useless. GPS radio/receiver also seemed to be defective. To make a long story short, it has been returned to Staple as we are within the holidays/14 days technology product return & exchange timeframe - and, of course, all 16GB WiFi models are out of stock everywhere - ended up paying the difference & traded up to a 32GB WiFi model - S/N beginning with "CAO"s and has 4.1.2 on it
Noticed the immediate difference - this one is perfect and no hardware issues whatsoever - and so far so good and with all the issues cited about 4.2 - staying with 4.1.2 for now by disabling the fraemwork, etc. to stop the annoying OTA upgrade reminder. Unlocked & rooted, tweaked it with the goodies & Flash Player 11.x loaded with Chrome browser removed, this is what a N7 should be like.

I have had a similar issue twice. I was reading a webpage when all of a sudden a pop up appears asking where I want to send it to, then it gives me a list eg. Dropbox , email, etc. I never press anything and I didn't even know what wanted to be sent lol. Hopefully its nothing serious.

[Q] Mytouch 4g wifi not functional after LCD replacement

I just recently replaced a malfunctioning LCD and shattered digitizer for my Glacier. Before I did that, the WIFI worked just fine. No problems at all. But now, the WIFI will turn on, but won't pick up any networks at all. All my other phones pick it up just fine, as well as my laptop. I've tried three different ROMs and I have the same issue with all of them. As far as I know, there weren't any cables that connected the WIFI module to the motherboard or anything else when I took it apart and put it back together. It's just a little piece that snaps into place, right? I'm not sure what's going on with this...

Seriously? Nothing? Every time I post on here, I get ZERO response... What gives? I see everyone else's problems being solved but not mine...

Sorry, there's no help to give. Don't act like you're entitled to something. I hate people like that. If you didn't touch the WiFi module through the screen and tried different roms then it went bonkers and its toast. TF are we supposed to do about that

If you're gonna post on here just to be a douche, you might as well not post at all. It's doing nobody any good.

All drama aside, he is right nothing to be done really. I guess you could open it back up again and risk breaking something more important than the wifi. Something may be put back in wrong or may have got ESD damange. Truth is unless you're just using this phone as a toy/dev/learning device and don't care if it breaks it is not worth the risk to open it back up.

Trying to fix my external speaker - I mess up working wi-fi. In addition, the case crack and camera button is not working. Should take it to repair shop. Too late now. It would be too expensive to fix it. You my still be lucky and shop will fix for few bucks. Lesson learn - do not mess with something that you do not understand( for me).

coax cable issue
there's 3 little coax cables - I've been told the white coax is the wifi but the black one fixed it so maybe they are all involved. In the process of getting to the LCD you went through these 3 cables. In most cases you wouldn't have disconnected them but certainly by accident it will happen. I put mine on 3 times before they stayed. There's quite positive click when connected but even then it may come loose while assembling the rest of the phone. I just finished swapping out my mother board and as perfectly as I could reassemble the phone I apparently lost one of the coax connections = no wifi. Went back in and this time the black cable somehow got caught under the camera board instead of on top and connected. Easy to see why this was missed because it looked connected.. well looked like it belonged where it was (wrong)
Anyway that's my wifi fix story - hope it helps someone
