lockbot break touchscreen?

Hello all, im still having issues with my touchscreen being i guess mapped incorrectly or sometimes hardly working at all. The more i think about it the more i have to think it can be fixed and also i think about anything that could have happened to the phone b4 it started acting up and there was nothing, not a drop or hit. The only thing i can put on the same timeline is right after i installed lockbot is when it started acting up, is this by chance only or is there a chance lockbot modifies a file that could affect the touchscreen? Any help with this or even ideas would be great. Thanks, veritas
Ps...also after searching google for a few days i noticed a good bit of people posting that they had diff issues after installing a couple diff lockscreen apps, the only issue is that they are all only open post with zero responses to point in the right direction. Thanks

This happened to me too after installing lockbot.
I'm gonna try to reinstall the firmware and will get back with the result.
Currently it just comes and goes .. mostrly comes.. The bottom part of the screen doesn't work at all, and the sliding seems to work harder. Also, when I type a message in landscape, I press a key, and another one is actually shown to be pressed.
I also tryed different versions of lockbot, 1.8 and 1.13 before the touchscreen sarted to have problems, but when it actually happened, I had version 1.8 installed and it froze when I was using it.

Just reinstalled originial firmware, and problem didn't go away.. this is starting to get serious..

i seriously doubt it's related to lockbot. many people use it with no issue.

yeah.. lockbot might have been a coincidence.. I realized that I was using a different charger (not the original one) when using the phone when this problem appeared, and this seems to be consistent with the problem.
Actually I was charging the phone from the usb port of the computer, using also an USB extender.
I'll take the phone to waranty .. I tryed removing the battery and not using it for a day, leaving it to use up all the battery.. no success.
I think that there may be some wild static running through the phone from when I charged it off the usb.
If I play with the phone a lot now, sometimes the bottom part works bot not the top part.. and sometimes, I can press something on the screen just by hovering the thumb over it.

I'm getting the same problem! I press at the bottom of the screen and it selects something in the middle or nothing at all and at the home screen I won't even touch the scrren just hover my thumb over and the screen responds like its trying to go to the next screen but then gets stuck in the middle.
I called t mobile and they said to soft reset or hard reset, did both and no fix.

It's definetly a hardware issue.. it's sad that these touchscreens are so sensitive to the charging currents..
I would have imagined that they would have added some protection for this ..
btw, it's not just a htc hero problem, the web is full with all types of touchscreen phones being afected when using non original charger.

That's ALL T-Mobile knows how to do. Reboot your phone or reset your phone. If that doesn't work, they tell you its broke. Anyone could do that job.

ANY phone gets affected when using a different charger. People don't stop and look at the voltage of the new charger and leave their phone on it for 10 hours even though it's charged.
You can't protect from stupidity. Not saying any of YOU are stupid, but seriously, don't give your phone 100 volts when its made to receive 12.

I quess that ppl that use non-original chargers would read the voltage output..
Like I said above.. I just used the usb port from the computer to charge, if this is wrong, maibe they should have disabled it

I was saying here that other parts of the phone are just fine.. if there is a problem with the charger, why doesn't the whole thing brake.

[Q] [DISCUSS] Screen usability while charging

When my phone is plugged into the charger, the screen becomes almost unusable. Very hard to scroll around, different letters get selected while trying to type. If i hold my finger still on the home screen, it jumps around like its having a seizure and wont stay still. Unplug the charger though, and everything works perfectly.
Was just wondering if anybody else finds it difficult to use the screen while charging, or if anyone notices any difference in screen sensitivity while charging?

I don't have your problem.

Neither have I encountered this problem
Seems like you have a faulty device. I suggest to go to a SE center and ask their opinion and maybe ask for another one

I just found an old charger and tried that, and no problems at all, so the issue is something to do with the charger im guessing. Weird....

my phone is connect to the PC and I am not having any problems, did you try charging it through a PC?

i encountered the same issue when charging with a nokia n900 charger.
while with PC charging it seems ok.

Not had that problem with whatever charger I use. I have used the in car, desktop and PC connections, also used an HTC and ZTE charger with no issues.

Have not experienced this problem.

I had this problem and managed to fix it.
Mine had nothing to do with the charger though. Typing went crazy whenever i hit the space button or the p button. Pressing p would produce a 2-3 y's and pressing space would produce a , and 2 spaces.
I cant remember EXACTLY which fixed it but i can tell you what i did -
1) Installed a cache cleaner. Cachemate. (although i have recently switched to Android Assistant). Performed a power cache cleanse with Cache Mate.
2) Went to Titanium Backup and selected "Default Input" and "wiped Data".
However, here is the thing i THINK fixed the problem -
1) Went to market place and installed gingerbread keyboard and selected it as my default input.
Switching which keyboard you use i believe resets the touchpoint settings. I prefer Gingerbread Keyboard btw, use it as my default now.
Be careful when you wipe cache or data using titanium backup. I accept no responsibility for any misuse that causes your phone to function incorrectly

A lot of Android phones do this with incompatible chargers.

Happens to me when I keep my phone on a flat surface it goes all mumbo jumbo and I can't even unlock the screen properly

"Jerky" / not accurate screen (video inside)

Anyone has this problem? When I put my finger on the touchscreen, screen moves up and down like crazy. It gets worse when I move my finger to the side of the screen.
I tried different roms, different kernels, nothing fix this.
Only when using the touchsentivity app and changing the value to any value and clicking apply makes this behaviour disappear for a moment.... after locking the phone and awake it, same thing happens again.
It drives me crazy because I always put my finger on the screen when reading something.. or in some apps or games when I need my finger stay on the screen it gets annoying. .

This isn't normal. If you can't solve this problem with a factory reset, get your phone exchanged or repaired.

That's what my HD2 used to do. Couldn't type anything on it to save my life. Think I'm gonna have to check my SG2 now I've seen your vid.

Thats probably because the custom kernel your using has a different value for it and the app is setting up 5, try it with a stock kernel and perform a factory reset and see if the issue still occurs w/o changing the TSP value.

I got the same problem. I do that sometimes too.. scrolling up and read while holding my finger down, it just jitters or something.
You're not the only one, but not sure how widespread this problem is or if it is normal or not..

Mine is also jerking when holding the finger out at the edge lol, looks retarded

Interesting...so if I disable the touchscreen fix the problem goes away. If I reinstall it, no matter what the settings are, I get the jittering effect at the very corner of the screen.

Yep I got same problem, when reading and holding down on the screen it does the same.
On Litening Rom 1.5 cant remember if it happened on stock rom though

I get this too, my SGS did it as well.

I tried this multiple times on the edge and it does not jitter at least on the phone that I have.

Mine did this when it was plugged into the mains (using a non-samsung) charger. Does not do it when plugged in via USB or on battery.
Is yours plugged in?

So some have it, some not?
I always had this thing, since KE1.. now on KG5. Stock kernel, custom kernel, rooted or not rooted doesn't matter.
Also, it has nothing to do with the touchsentivity app. The app even fixes it temporary when applying a new value, but it re-appears when locking-awaking the phone. (I tried to enable the service option on the app, so it will apply the value everytime I awake the phone, but this does not work)
I just tried it when plugged in in the changer, it seems to do the opposite... when plugged in I don't have this effect anymore. Once plugged out it starts again.
I also have SGS1.. this does not happen.

So how has this worked out for you? I have this too but just a little bit less. It also stops for me when plugged in. I wen't back to the store with it but saw that the shop model had the problem too so I decided to not return it. How about you?

I checked and it appers that i have i too. Didnt notice it till now.
It is occuring only on the left side when holding my finger.

I did not notice it too...and yes, mine is "Jerky" too...

Mine is fine, so looks faulty to me.

weird left side
I have to say this happens to me too but only when at the VERY edge of the screen,on the left.
There is something very weird about the left side of the phone.
1. the touch issue
2. the yellow tint
3. the glass is more raised than the right side(check it out) its like there is less bezel showing on the lower left part of the phone than the right side. I've checked 3 s2s and they all had it.

I have this all over the screen but not as bad as on the left side. Could someone install note everything and make a paint note with the smallest brush. Then try to make some straight lines (without the phone being connected to the a/c). Draw them really slowly from the left to the right. Mine usually jumps 1 pixel up and/or down and is a bit wavy (which isn't normal for touchscreen phones cause I tried the same thing on my friend's optimus 2x and the lines where as straight as could be). Maybe if you guys make a screenshot (home button+lock button) we could compare them and see if there is really a problem with specific phones or with the Galaxy line in general.

This was something I noticed when I first got the phone, if I kept my finger on while browsing, it would "shake" and be extremely annoying. Same thing happens when you hold an application in the left corner of the screen.
If my phone is charging, the problem is gone! It's smooth, and doesn't "shake".
Soon as the charger is removed problem is back
Going to return this tomorrow and see if they'll exchange it.

Just another 'my phone is red, yellow screen thread'. Does it affect your day to day usage? If it does,i too is concerned.if not, then what's the point in looking for non measure issues? This issue was up like 4 months ago and now, back. Y'all just return your phones and close annoying threads.

Touchscreen problem.

I bought my TF300 at Amazon June and basically it works well until yesterday.
The sympton is like someone keep tapping the specific areas of touchscreen and never stop, actually i haven't put my finger on ,even i didn't hold the tablet, just put it on desktop.
I had to tried to hold the power button to restart the TF300 several times and finally it looks become normal.
But this morning, when i power it on, the problem occurred.
Anyone have idea this problem ?

Weird. Do you have a screen protector on? If you do, you might need to take it off. If you don't, try cleaning your screen with the cloth it came with, also do a cold reboot (this is done by turning off your tablet then turning it back on holding the volume down button until you see some text in the upper left of the screen, after that just leave the tablet do he's thing, meaning don't touch anything else until it boots up). If that doesn't fix the problem, you will need to try to do a factory reset. If that fails to fix the problem I suggest you contact ASUS support or if its still under amazon's warranty exchange for a new one.

Thanks for your suggestion.
I found a member had the some problem. See thread: http://forum.xda-developers.com/showthread.php?t=1653178
I gotta to contact ASUS local first.
A friend of mine bought it in Amazon U.S for me and bring it to China, which makes me hard to exchange ( International post fee and custom tax).

I had that problem

Mine wasn't picking when I pressed on the screen... I open the back and saw a ribbon cable was kinda loose and held with tape. So I pressed it in and put more tape on it and now its fine with the response from the screen.

I've noticed differences touch responsiveness between different roms. What are you using?

stock rom , US .30 ,i think.
It rooted.
since the day i posted the problem here,i used out the battery and recharged it to full,the issue didnt happen again.
what i can recall that before the problem happened,i had connectd it to my PC by USB cable,maybe it is another clue about cause.

yes,i am using the screen protector since the firstday I owned it, it works well until that day I met problem . I recalled I had connected the tablet to PC with USB cable once, in other thread ,same problem happened after it removed from dock, probably it is the clue for cause

Fix for touchscreen issues
Hey guys,
I thought I'd post my solution to the same problem. It is a hardware issue and I figured it was because of how thin the device is. Basically, I noticed it when I would be playing or if the device started to heat up. Since the battery and screen are so close together, I figured there wasn't enough space and that the heat from the battery was making the tablet think that there was a touch input when there was none.
My solution was to open up the tablet and take the battery out. Then I put slivers of foam (about 1/2" x 2") in between the battery and the screen. Since then I haven't had problems with the touchscreen.
I hope this helps you guys with this problem.

Need Advice N7 Screen issue.

Hello-
I usually do not open threads but I need advice on this recent touch responsiveness issue that has been happening. My Nexus 7 8 GIG was running great I had not had one issue with it, until one day I opened the case "Poetic leather case with magnet locks" and the screen came on notifications were on and animated everything looked fine. I went to unlock it and the touch screen did not respond to anything, now the screen rotates fine and all but it would not respond to touch. So I reset it with the power button, the touch screen then works until it times out and turns off, I wake it up and the screen does not respond again. I took it out of the case and have manually turned it on/off and it still does not respond to touch, but it will work every time I reset it. This problem has came out of nowhere it was running great.
I was originally on AOKP Milestone 1 with Franko's Kernel r25 so I thought maybe that was it so I re flashed Milestone 1 and kept the stock kernel and the problem persists. So I wiped everything and put BAMF Paradigm on it and it still does this, but the touch screen responds every time it is manually reset so I am trying to figure out if this is hardware or software related I am led to believe it is software considering the touch screen works flawlessly upon reboot but again I am not sure.
I have not added any new apps or anything like that to cause a memory leak or such. This problem started when I left the N7 for two days without touching it, then the problem happened after I tried to use it after the two days of inactivity.
Update: I turned the N7 off for about a day booted it back up now the touch screen is working every time I am confused.
So I still have 7 months on my ASUS manufactures warranty should I send this unit back? I just do not want to think its software related and it will get fixed through updates and then find out it is hardware related and be out of the warranty period.
I am on 4.1.2 with the last boot loader "not the new one"
latest version of TWRP
Thanks everyone in advance for your time.

It seems like a magnet bad effect to me! not sure though cuz the nexus 7 suppose to work fine with magnetic cases but it could be a Magnetic field effect. In my opinion as long as it works don't send it cuz you don't know what happens there in the service center, I mean once the device is opened it would never get the same as before.

Yea I had thought that was it but I took it out of the case and still does it so no dice on that field

well i flashed the latest google image and just started fresh. The touch screen is now working without issue so hopefully it was nothing still not sure though what would have caused this though -_-
