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!!!

[Q] Why do we put up with it?

Not sure where my previous thread went, I didn't think it broke any rules?
So we have the latest WW update now and it still doesn't fix the SOD issue, do we not have any legal rights against ASUS? Why are we just accepting it? Yes, we have custom ROMs which attempt to fix the issues that ASUS can't, but even those aren't successful.
Every time I come to use my tablet it's either in a SOD or the battery is completely drained, when I was on HC I was able to get 5 days standby pretty easily and not once do I recall it rebooting or having any other issues.
ASUS turn a deaf ear when I try to get an answer from them on their Facebook page, either ignoring me or deleting my posts entirely, I suppose the next step would be to start an RMA request to see where that gets me but I honestly don't think it's something their the RMA centre can resolve as it's affecting so many Transformers.
I'm really frustrated with the whole thing, my Android phone works flawlessly, an SGS on 4.0.3, but my tablet is such a nightmare! It's really soured the experience, so much so that I don't think I would want another, add to that, I don't think I will buy another ASUS product due to the lack of support they've given me (I'm only 6 months into a 12 months warranty as well).

I too an saddened by my transformer's performance as of late. Mine is getting worse I think, Not sure if it's because of the flashing different ROMS or not. I've only really flashed two different ROMS. EOS and AOKP.
Now after a fresh flash my tab just freezes with the screen on, touch inputs do nothing, the screen is frozen. I will force it to shut off and it will not turn back on, or it does turn on in some way but nothing on the screen appears, I have to leave it for a day to drain the battery.
Since ICS I do not even use it, I can't. Really saddened, it could be a great device but it is now just slightly better than useless. End of rant.

My TF700 shut down automatically

Hi,
I just got my Infinity for a few days but there is an annoying problem.
Sometimes it shut it self down automatically and doesn't wake up by pressing neither holding the power button. The reset hole was my only way to get it start up again.
My pad is running on the latest update from ASUS, which is 10.4.4.18 and everything is stock. I haven't unlocked the boot loader, rooted or anything.
I contacted ASUS and they just told me to do a factory reset or suggest that my pad has a hardware problem.
Please help me out!
Thank you!

Have you tried a factory reset? It's probably good advice right now..

I did but it still shut down automatically
I'm thinking about rooting and try the custom roms if it help

Did you have the shutdown bug when you first got your tablet?
From a tablet running CleanROM 2.3

My advice would be to do a factory reset and see if you have the problem before loading *any* apps. This will rule out an app issue causing your problems.
If it still happens without any third-party apps loaded, then I would exchange it (or RMA it if you can't exchange it).
Remember, once you unlock the bootloader (which is required to load custom ROMs), you warranty will be void. So make sure it's not a hardware problem before trying custom ROM's...
Yes, it's a real PIA to do this (factory reset, test before loading any apps, etc), but it's really the only way to determine if it's a hardware problem or not...

I agree with what jtrosky said. Factory reset and don't install any apps (besides from the ones already pre-loaded). If it still is shutting down then it's probably a hardware issue and I would get it exchanged.

TF700T shuts down when docked
I've had my TF700T for about 2 months now.
I first experienced this shutting down problem about 3 weeks into using it (was under 9.4.5.26 at the time I think).
It appears this occurs only when the tablet is docked and I close the lid (as someone else stated in another short thread).
I've since had all the OTA updates up to 10.4.4.20 and the problem persists.
* A factory reset does not help: I did a few today and did not install anything
* I tried different combinations of settings (mobiledock battery saving mode on or off, disconnect network during sleep on or off...)
* I tried with dock battery empty or charged
I just have to close the lid, wait for 2mn and it's down.
I usually restart the tablet by holding down the power button for like 15s, then again to start so it looks like I first have to force shutdown, then start.
No problem if I don't close the lid and just let it go to sleep.
I'm wondering whether only the tablet, only the dock or both are involved in this.
Current build is 10.4.4.20 (WW)
Pad EC version is PAD-EC20T-0216
MobileDock version is DOCK-EC20N-0207
I suppose I'll try to RMA it

Before you return it, try to download the full version of .20 , do a factory reset then reflash the full firmware. It fixed my shutdown issue.

thats just normal with our beloved Infinity. It has all kind of shut downs, lags and other stuff. It makes this more personal product.
My also sometimes shut downs when I have it docked and closed the lid. Not very often but sometimes. Makes it kinda exciting if you have alarm on the tablet and never can be quite sure if the pad died during your sleep or will you wake up on time 8)

The things you mention are *certainly* not "normal"! If they are constantly happening, I'd guess that you have a faulty device. I have *never* had a single random reboot, sleep of death or any type of "automatic" shutdown or reboot and I've owned the device since it was released...
Just wanted to make others well aware that none of this is "normal"!!
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2

well, for the past few days I could reproduce the shutdown / sleep of death 100% of the time... today the tablet stays awake. I have not changed anything since...
Not too confident for the future though...

Since last post the sleep of death has come back. I have tried reflashing the full 10.4.4.20 firmware to no avail.
A friend of mine with a Prime says she has the same thing, but only when the dock is completely discharged.
I have a feeling it appears on mine as soon as the dock has charged the tablet at least once since last full charge. My testing was not consistent enough to confirm that though.
Anyway, I applied today for a repair with my local reseller (Darty) who categorized that as "firmware fault"...
Now it's wait and see

Shutdown/Freeze problem without dock
I have been having the same problem and I'm not using the keyboard dock... I think the tablet just freezes thought since I have to hold the power button for more then 15 seconds to power it back on.... I'm also on the latest 10.4.4.20 firmware.
I think I'm just going to exchange it for another one since it doesn't seem to affect every TF700 device out there....

Got mine back 2 days ago... and sent again back today to my reseller's warranty service.
The ineffective solution was a firmware flash, which I had tried times over anyway.
This time I had the opportunity to demo the trouble at the counter.
Waiting for next try.

forward to asus
Just for the record, my reseller's support service was apparently not able to find the root cause and reported they've sent the device to Asus today.
Waiting for more news!

so I got my Infinity back two days ago.
The tablet has been in my reseller's hands, then sent to Asus in Czech Republic.
I have no idea what has been done... and the fault is still there, though the sleep of death does not appear all the time... only a lot.
Only things I did since I got it back were: connect to a wireless network, OTA-update to latest build, connect my Google account and update pre-installed apps.
My reseller says "no fault found", which is obviously their latest observation (after they got it back from Asus), not the full story (they wouldn't have RMAed it otherwise).
The RMA number on the box gives no result on Asus' website.
I guess I'll have to send it back again... or check other exchange options.

end of that story
After 4 trips to my reseller, 2 trips to the Czech Asus service center and a total 81 days in repair shop, somebody finally acknowledged something was faulty and "some parts were replaced".
Finally got rid of that "dies on dock" problem.

Wow!
This has been quite a trek for you.
You have really stayed in there with your problem.
Thank you for the updates!
:good:

well, the riddance of my original problem was the good part. Other problems arose:
Now I occasionally see the infamous black line I had never seen before.
and I can't unlock, which might be related to having had RMA as stated several times in this and other transformers forums.
anyway, that's another story.
thanks for the support.

Touchscreen unresponsive when dock is connected

After updating OTA the other day (I've always been on stock firmware), my tablet seemed to be working fine. However, once I connect the dock sections of my touchscreen become unresponsive. I can still scroll and click with the touchpad on my dock and parts of the touchscreen still work. This only started happening after the update - without the dock my touchscreen works perfectly (unless I connect the dock first, in which case I need to restart my tablet before the screen works again).
I'm not sure if this is an issue with the update or if anyone else has experienced the same problems. Hopefully someone will know what's up.
Any help is appreciated!
Edit: Was playing around a bit and realized I could "fix" it by locking/unlocking the tablet with the dock connected...so I suppose it's not a hardware issue but rather a problem with the new update.

After the 4.2 update, my tablet has also become totally incapable of working with the dock connected.
Everything stops working as soon as I connect it; Seems even worse than what you're experiencing.
I hope Asus knows this, because I am sure it has to do with their update, not my tablet

Mmmmhh... So far for quality control? I really do feel f r you guys, asn many of you will not have been able to unlock, and therefore cannot go the custom route. (Especially sad for you, adelancker, since your tablet was unlocked originally!)

You tried a complete system reformat. Restore to Factory?

with the dock connected? You can't
Without the dock connected, yes, and got no results
Hahaha, Asus really messed up good.
@MartyHulskemper I have been able to unlock after a lot of whining!
But still, the problem originated from before the unlocking itself...
But you might have given me an idea!!!!
I can try and:
1) make a nandroid
2) go back to 4.1 Cromi
3) connect the dock: see if that works
and then try to
4) flash 4.2 Cromi-X on it with the dock connected.
Maybe that'd help?

Did you apply the update with the dock detached?
Have you tried rebooting with the dock attached? If that does not solve it, I would reflash the last update with the tablet docked.

The update was applied without the dock. I tried a factory reset to no avail - although, cold-booting a few times seemed to make the problem less frequent. Restarting with the dock connected had no effect.
Strangely enough, I noticed the system bar lock was enabled by default (it was disabled before the update), once I disabled it again I noticed an immediate difference in the performance of my tablet. Much less frequent lag/unresponsiveness with the dock connected - No idea why this would make a difference though

I can say that I did that update to 4.2 without dock, I am afraid.
I have tried rebooting, but it just won't boot as long as the dock's connected...

I have the same thing* . Tried many things hard reset, cold boot, downgrade..but unfortunately nothing helps :/
Now I want to drain completely battery-especially in mobile dock
*The same thing means tablet is unresponsive when dock connected(I can't: boot with it, lock scren, neither make factory reset)
Fortunetly I still have warranty, but can't give it now, because I need it for holidays. So did you find something that could help me?
Temporary solution is downgrade to 4.1(10.4.2.20), then it doesn't lag and I can use USB port so I can have keyboard and mouse, but this isn't mobile solution.. (sometimes it also charges from dock-I think when tablet battery is below 90% , but when dock is connected to charger, then it charges whole time)
I don't remember if I made update with or without dock connected.

[Q] Newly Rooted TF101 is resetting time and date

HI
I got a new (to me - but it looked like new anyway) TF101 for my OH, rooted it using PERI as Easyflasher just would not take, installed KatKiss 4.3 v29 and it is running fine, except, when my OH turns it fully off and restarts it the time resets to 00.00 Jan 01 2000.
This does not happen with my TF101 which is running the same ROM.
I have tried it with both auto time and date and with manual time and date and neither stop this from happening. As soon as she connects to wireless and has auto time/date enabled it corrects itself but I'm curious as to why this is happening. Does the Bios (do tablets have a bios) have a separate battery like PCs have.
Any help will be greatly appreciated and thanks for all help in the past year and have a Great New Year everybody

Nobody? Wow didn't think this issue was that rare/difficult.

I know this post is a little old, but I had the same issue with my TF101 and I managed to fix it.
I noticed after watching a tear down video there was a very small cmos like battery at the top of the device. I figured that my battery must be dead and decided I'd take a crack at opening it up and replacing it.
Turns out the battery wasn't dead. One of the wires had broken (if it was ever properly connected at all) right at the connector. I used a razor blade to clean the broken wire out of the connector, cut the frayed end of the wire off and pressed it into the connector (the connector is self tapping similar to a RJ-45 cable end).
It's no longer New Years Eve everytime I turn the tablet on!

another solution that doesn't require to open the device is to install NTPsync and auto sync at boot.
Regards
