Touchscreen Jitter Issue

Ok so i picked up my new skyrocket 2 days ago and I put CWM on it, made a back up and installed the ICS flavor ROM from the development forum. Everything went fine, and i didnt use the phone much yesterday, but today i noticed that i am having annoying touchscreen problems. It basically makes Swype unusable. I have restored back to stock and it was still doing it. I have reinstalled the ICS rom, double flashing it, and it still does it. Is anybody else having issues like this? Its noticable on lists. This video is just an example but it does it in the market, on web pages, etc..

I have never had these problems. Maybe take it back and exchange it.

Update:
I used odin and i reset everything to stock with no CWM and no Root and the issue has stopped as far as i can tell. Maybe i just had a bad download. Ill redownload it again and flash it tonight and see if it persists.

Ok so ive been using stock and it started again. I used an app called Touch Test to see what the screen is seeing. It is a really intermittent issue. There is a "ghost touch" that is happening. near the top of the screen and at the bottom of the screen. A touch in the middle causes it to jump to the top and then back to the bottom causing touches to jump all over the place. It is very intermittent. I didnt buy the phone from ATT so there could be 2 reasons for the this.
A) It was sold to me like this
B) The people at ghost armor put to much liquid on my phone when applying the screen protector and messed up my phone.
I didnt notice any issues before i got it ghost armored, but i only had the phone 2 days before i got it wrapped.
Any ideas on how to recalibrate the screen or any other options i may have?

Found the culprit... Kind of embarrassed it took me this long. Ended up being the wall charger. Its a cheap knock off but it had the same input and output. I was sitting at my desk on the touch test app seeing it spaz out and unplugged it to show my friend what was happening and it stopped. Used the same cable to plug into the pc and no problem. Well that is a relief.

Wow, thanks a lot for this info man! You really saved my life.
I also got a new charger and started experiencing these weird jitters. If it wasn't for this post I would never have figure it out.
My new charger was an Original one from Samsung, but it was obviously made for a different model as the output voltage and current were higher = caused jitters.
I then went back to using my old charger which came with the phone and the issue is gone.
Using Samsung Galaxy S5 NEO (SM-G903F).
Thanks again!!!

Charging Problems

After not using my tablet for about a week, I plug my tablet back in to charge, and when i check on it, the tablet, freaks out. It shuts itself off completely, and I felt that the area on the tablet where the ac adapter plugs in was really hot and the plug that went into the tablet actually burnt my finger it was so hot! And it smelled like something was burning...
Now the tablet will not boot past the Bird screen and it does not show any messages telling me what is wrong with the tablet. I can't boot into CMW, I can boot to APX mode but it doesn't connect to my computer.
I have no idea what to do if anyone has any ideas, shoot...

The obvious thing would be to open the tablet up and look inside. If components are burnt, then send the tablet back to VS for replacement. If you can't see anything obviously wrong, then look through this thread. It has a kernel (1.1 bootloader only) which prints boot-up messages and going through them might tell us what's wrong.

Thanks for the reply!
Problem is that I'm on BL 1.2... And I can try a few things, but I figure without recovery mode or APX Mode, there isn't much I can do about that...
How much hardware is there to remove to get to the parts around the battery/AC Port? and should I maybe find a guide on how to take apart my tablet?

Should I plug it back in and see if it gets really hot again because right now it has no power and won't turn on at all?
Or should I see if there is a way for me to NVFlash so I can send it back to ViewSonic?

Send it back. The fact that the charger port is getting hot and that you smelt something burning is indicative of a bad hardware problem. You'll most likely end up sending it back whether we diagnose this problem or not.
And, I wouldn't worry about the custom ROM on the tablet. Other users have reported that VS doesn't really care about that sort of thing. Expect to be charged a small additional amount on account of it though.

I'm worried cause I was reading some previous posts on the subject of VS not replacing gtabs that were flashed, and they were very angry with ViewSonic for not replacing their tablet. It said the customer service being very annoying about people flashing different roms... I just want to make sure everything will go over smoothly...

Does anyone have an email address or a number that I can call for ViewSonic, I can't find it on their website? Thanks!

The Viewsonic G Tablet Support Line per the warranty card that came with my device is no longer working.
It was kinda tough to find, but phone is: (800) 688-6688
Good luck.

Thanks!

I have a G Tab that wont turn on either. Viewsonic gave me US Merchant's number to get it replaced.
310-228-4000
No one answered, and apparently option 1 for Customer Support doesn't even work. I was able to leave a message, but I have no idea who I left the message for!

[Q] Hard brick from OTG cable

I just hard bricked my second GS3. I bricked the first one a couple of months ago (the day I got it) when used a cheap OTG cable to attach a flash drive to the phone. The phone just shut down. No charge light ever, no response to usb, just nothing.
When I got my second phone, I took a deep breath and tried the OTG cable again and it worked fine. I thought I just got a bad phone.
But today, on a whim, I wanted to see if my phone would run an external USB cd drive. BAM, the phone shuts down and is hard bricked again!!
So, I guess this is a cautionary tale, as well a plea to the community for any recommendations. Someone had a similar problem months ago, but I didn't see a resolution. I will probably end up sending it for JTAG repair, but I don't know if it will do any good since this wasn't caused by borking a ROM install. Anybody have any experience with this?
One thing is for sure. That OTG cable is going in the trash.

I have never heard of this. Very interesting. Sorry to hear this for you. I have been using my cable for awhile now and only ever had one problem with it. I was viewing pictures and looked away from the phone for a few moments. Phone went into sleep mode like normal. Dull screen then screen off. Prob was it wouldnt wake up. Nothin i did woke it up so i had to do a battery pull. Phone was fine after that and havent had the problem since. Gonna keep fingers crossed after reading the OP.

Yeah, it is a real pain. I found some other people who had the same issue.
http://rootzwiki.com/topic/32816-sgs-3-and-otg-usb-adapter-might-equal-brick/
I just can't imagine what must be happening. I wish one of those uber-smart hackers who were working on the bootloader unlock would see this and give me some idea if it is even fixable. It is almost like it blew a fuse.
Anyway, I have an email out to mobiletechvideos to see if they think it can be jtag-ed. I have a feeling that a $2 cable is going to end up costing me $600.
----- Update -----
I made and tried a usb jig, just for kicks. No luck. Still waiting to see if mobiletechvideos gets back to me.

Another quick follow-up... I got a response from mobiletechvideos.
Unfortunately that has been damaging many people’s phones. It damages the PMIC and the device is not repairable by any of our services or any other shop that I know of.

If you are too lazy to google PMIC, it is the power management chip. Sounds like there is a problem with the cable where the power is being directed somewhere it shouldn't be.
This weekend, I will carefully cut open the cable and see if I can see the problem.

Don't like resurrecting threads, but was curious for an update. This just happened to my Verizon GS3 as well. Completely unresponsive. I'm still under warranty so am about to go to the store to have it sent back, but came across this thread while trying to hunt down solutions.
Fwiw, it was with this cable: www()amazon()com/gp/product/B00932N46S/ref=oh_details_o00_s00_i00

[Q] ***HELP*** Transformer won't turn on.

My transformer will not turn on. I used it a couple days ago but don't remember if I fell asleep or powered down. I went to turn back on this morning but there is no response. If I plug in the charger I can see the light come on. Also if I hold the power button it will give a quick vibrate after about 10 seconds. Has anyone else had this problem?
Its rooted and unlocked. Any help is appreciated, thanks in advance for your time.
I forgot to mention that there is nothing being displayed on the screen at anytime whatsoever...

Try cold booting it? Turn it off and then turn it on while holding the volume down button.
Try connecting it to your laptop, see if detects it???
Maybe its a software app thing?

Already tried both. Problem is, is that there is no way to see if the device is even powered on... The battery meter on the screen doesn't even show up when its plugged in/charging...

Wow....that sucks.
If your computer doesnt detect it, then idk what you could do.... cuz if it did, then you could try to use adb to try and restarting t.
It sucks that its unlocked or i would have said to just contact asus to get it replaced.
Other than that, its hard to say...sorry man.

Held down power, volume down, and volume up at the same time.
Then tried the paper clip in the reset button by the hdmi input.
Then I tried both ideas again with the charger plugged in....
Frustrating. Unless someone has anymore ideas I may just try and send it in. Hopefully they cant tell if its been unlocked or not because nothing is being displayed..

You can't send to ASUS when you use unlock tool they get your S/N and save it in case something like this happens. The only way I can see around this would be if you bought it at a Best Buy. They maintain 1 year manufacturer warranties if you bought from them so you could feasibly take to geek squad/Customer service and say it just stopped working. They wouldn't have record that you unlocked the tab. You would most likely need the receipt or some confirmation you bought it there though. Good luck.

Sorry friend, seems like you are in real trouble. I had a very similar problem, my only solution was to exchange it:
http://forum.xda-developers.com/showthread.php?t=2203565
As you have unlocked yours, the warranty is no longer valid, and although Asus will fix it, you will have to pay to get it done. Since I'm on my second TF, and it even has had a problem that nearly bricked it, I am simply afraid to unlock it while still within the warranty period.

Might get lucky and see something with it connected to the HDMI port.

They did with my TF201 and this guys TF700 just a month ago http://forum.xda-developers.com/showthread.php?t=2240970

They took back my TF201 in August last year. I was told by BB it was done under the manufacturers warranty. It really does depend on who you talk to and how you approach them with the problem. Several people had to try different BB stores until they found that one person working there that either knew HOW to do it or was willing to take it back.

I had the same problem. Tried all the ideas mentioned above. I then put it on the charger for a day and afterwards it just booted like nothing had happened.

TF201 is a different tab and basically BB and asus came to an agreement to take them back. The guy in your link got lucky. Probably only got a trade because of the extreme nature of the defect. Fact is you cannot just go into BB and get a new tablet under mfg warranty.

Exactly.
Now for the good news. My tablet came back to life last night after 3 weeks of trying. It was totally dead and wouldn't even vibrate anymore. plugged it in and it actually tried to boot right away but then turned off. Let it charge for a few and tried again and it booted no problem. Battery % is now showing accurately and it has now been running fine for 12 hours.
My problem is I went out and got an HP envy x2 (win8) tab on saturday. Now to decide which to keep... I love the envy but the new quad cores are coming out this fall which should really make it a versatile little laptop. Just don't know if I can live with android now that I have a taste of full win 8.

Any updates? My TF700 stopped turning on as well. Same recovery efforts, now waiting on the battery to drain. I unlocked/rooted for cleanrom (faster/better). Worked fantastic till last thursday and it refused to turn on in my college class. This could signal my exit from Android even though I have a lot of money invested in apps.

Good to hear. Aside from the snappier response of cleanrom my biggest issue with the asus firmware was the waste of screen space on the home screen. It had like a 1" border all the way around that you can't put an icon in and that annoyed me the most of all. Been waiting the battery to go completely dead before I send it in just hoping that fixes it.

Dead GS3

So Tuesday I took a couple pics with my s3, then plugged in my usb otg to transfer some pics to that to put onto my ONE, then forgot about it. Last night i picked it up and noticed it was dead, thought that was strange but maybe i left wifi on and didnt give it a full charge before. So I plugged it into that charger last night and forgot about it. Decided wanted to take a couple pics with it today and its dead still. Like totally dead. I put a different battery in and still nothing. Been on the charger fpor a bit, nothing. I get no lights, no vibrate, nothing. Any idea why it would just die like that? Its a replacement from verizon from about August, used until mid september when I got my ONE. Kept my s3 for the camera. Any ideas what the issue is and if its bricked somehow? I was running andys bonestock, havent flashed or touched anything on it in sometime so a bit confused what the issue is.

It's bad luck, there's a whole thread describing this issue. As a general rule you shouldn't plug anything into the phone, but there's no way you Could've known that.
http://forum.xda-developers.com/showthread.php?p=33882126
Basically I'd check and see if you can plug it into your pc and see if it'll recognize it at all. Sometimes it'll show up as an unusual drive qusb_dload and that can be fixed. Alternatively, you can plug it into a charger without the battery, if the red light comes on that can be fixed also. If nothing works, you may have shorted the power supply which is a different problem.

Ive been using the on the go usb for a while now transferring pics i take with the s3 to my one and to store photos or other files from my ONE. Never had a problem with it. It is not picked up by my pc at all nor do i get a red light or any light with or without the battery. How do i determine if this is just a power issue and not a brick issue? Im not sure how i could have bricked it just by copying pics from the phone to the otg.
EDIT: So after reading that thread, im thinking this is likely my issue as well. It didnt happen immediately on plugging it in tho cause i was watching some of the files transfer before going back to watching my movie on tv. Is this issue just on the S3? Or should i be worried about this with my ONE as well since i have no sd card in that?

I think you're better off not using it, but I wouldn't know for sure on the one. The power issue would be a much bigger problem then a hard brick because getting parts to fix it might not be worth the cost. Plus you need to find someone who can fix that.
If you're still under warranty just bring it in and get a new one.
