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.

Touch screen random inputs?

I did a DIY digitizer replacement a month or so ago, and its been working great up until a few days ago. Now, when I go to touch one of the soft buttons or type on the keyboard, the phone "flips out" and starts registering inputs in all random spots, sometimes getting stuck on that spot. I am totally stumped.
I double checked and all the ribbon cables are seated and such, and tried flashing over to Modaco rom from Cyanogen (thinking it might be software)... no luck. Can't even replicate it consistently, it seems to have a mind of its own.
Any thoughts as to what is going on?

Well I know that it has been an issue for some people and the general idea is that if you push the power button and put the screen to sleep and then wake it back up 20 seconds or so later it will work again. I have to say to also wipe your screen clean as well, build up on the screen can cause wonky behavior as well. Good luck.

this sounds exactly like the glitch that all nexus ones have, stock ROM. just lock then unlock the screen and it fixes itself.
the word is that it will be fixed with the 2.2 update. fingers crossed.

I thought it was that issue I read as well, but the power button glitch-fix everyone speaks of doesn't work.
I actually used my pry-tools to unseat the digitizer from the rest of the phone and kinda let it dangle, and 90% of the issues disappeared.
I am wondering if it might be the digitizer pressing up against the metal backing thats causing it to ground out and cause these issues, since the original phone was held in by a foam-type adhesive which I don't have on it now.

that's very possible. the power button resets my glitch 100% of the time. so sounds like something else is going on with yours.

I don't think its the famous touchscreen issue that we've heard because it was reported to register a click few centimeters below the touch point. Here in this case, the guy says that it randomly registers clicks at different spots.

I hope that reboot fixes this problem....

I've given up on the task for now, went back to my iPhone 2G till I can figure this out... its definitely not software though... and the digitizer still registers accurately when I don't have it seated into the phone...

No issues here on cyanogen 5. 0. 6 I love this Rom and have 0, yes I said it zero issues..... running solid for almost a month.... sorry ya have them issues I hope ya get em figured out...

As others says, just a quick lock & unlock fixes this. No need to wait 20 secs, I do it right away. Power, power, slide to unlock and I'm back in business.
For me I'd say it happens maybe a couple times a week? What about other people?

On stock it happened like once a week.... for me
none on custom so far after 3 weeks

yeah a couple times a week is it for me too. I wonder if view identified the issue and fixed it in the update. I'm sure some Google employees experience the bug.

Screen Touch Response Issue

Hey, I'm new to the forum here, and would like your feedback on this aria issue I'm having. Here it is: when my aria is plugged into the wall to charge, the touch response of the phone is drastically changed. If I tap my finger on the screen, or any of the four buttons, it double clicks - in other words I can't do a long click (click and hold) nor can I operate the phone very easily, it also won't really follow my finger if I drag it across the screen. My phone isn't rooted, rommed, or anything, just plain stock. I haven't dropped it, scratched it, I honestly don't know what I could have done to trigger this.
I've attempted the following to fix it (obviously each yielded an unsuccesful result):
1. Restarting (both plugged in and unplugged)
2. Shutting down, removing the battery and sim, and starting up
Does anyone else have this issue? Anyone have any remedies for me? Thanks for your help.

I've only had mine for about 3 hours, but I haven't noticed any issues with the screen when the phone is plugged in (and it was plugged in the whole time).
Maybe you got a lemon?

You may want to take it back for an exchange if that keeps up. Mine has been flawless since I got it on launch day.

Might just have to. I tried doing a factory reset - that didn't work either.

It sounds to me like some sort of grounding issue that is screwing with the capacitive touch screen.

Good call tshooter. I tried a different plug and voila, no issue. The charger is only 2 pronged (no ground) so I don't know why this would have been an issue, but I'm no electrical engineer.
I'm happy as long as it keeps working.

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.

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).

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.

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.

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.

[Q] momentarily unresponsive touch screen

Hi guys
I have moved from iPhone to a note 4 and loving it!
I was just wondering if anyone has found the touch screen occasionally doesn't respond to their touch and you have to touch it again. On the iPhone it only ever missed a touch if my finger was in the wrong place, but it never happened on the keyboard. Every so often maybe 5/6 times a day I touch a key on the keyboard and nothing happens, when I try again it's fine. I can't reproduce it, because when I tap anywhere on the keyboard something gets pressed. I was just wondering if this was normal?
Hope you are enjoying your phones!!

Anyone?

It's most likely cause your palm is on the phone. One of the downsides of a slim bezel on a big phone. Also keep in mind if your spen is on the screen, your fingers won't work. A case might help.

I thought about another part of my hand touching the screen, however with half my hand layed across my keyboard I can still type with the other hand. Thanks for the response

I Pele tried factory resetting today and not installed any apps, but it is still happening

I rang Samsung this morning and they advised I return I to the store and get an exchange. Luckily my local store got its first batch of note 4s in this morning and they swapped it out. I restored it all firmware updates put on it and now works fine! The only thing I haven't installed is a Google play system update thing. I was wondering if that was the cause x

Similar issues
I've had similar issues (in fact, that's what brought me here in the first place). Initially, I was able to tap on the screen in the text box and then continue typing (I use Swype). However, now my messaging app (default Messages) just freezes up, forcing me to close the app, clear the memory, and relaunch the app before continuing.
Were you using the default app and/or Swype when you had issues? I'm going to try to factory reset my phone to see if it helps.
It's taken a couple of weeks for this problem to develop, so please keep us posted if this problem arises again on your new phone!
Edit: Also want to point out that when I text, I use one hand to hold the phone and only a finger to swipe my text. As such, only the one finger touches the screen.

unable to use touch screen. only hard key were working >>Note4
Hi everyone,

Same thing happened to me last night. The touchscreen became unresponsive while using chrome. The phone was a little warm but not bad. I didn't try the pen, sounds like a good idea. I am not certain it was a touch screen issue with mine. Almost more of a processor issue. I got the phone to lock. After pressing the menu or lock button to wake the screen it would take 5-10 seconds to wake. Then I could swipe my unlock pattern. It would not show any lines. I would wait, the screen would turn black after timing out in about 5s. The about 5s after I could hear the speaker make the unlock sound. I ended up doing a battery pull and that fixed the issue. Anyone else have something similar?
Should I try and replace it?

Observe to see if it happens when you're using other apps too. Chrome has been notorious for causing all sorts of problems, like reboots, freezes, etc on some devices.
Also it may be worth installing Chrome Samsung Support Library.

Got the same problem after 2 months of normal usage... I initially though I had installed a third party application which was causing the system freeze but this was not the problem.
- tried factory resetting and not installed any apps, but it is still happening
- When this happens if I take out the spen .... surprise it work. The pen allows me to do anything... But the touch screen does not work with fingers...
- I used the pen to reboot the note4... Still the same problem after reboot... I ended up doing a battery pull and that fixed the issue for.... a couple of minutes... Then the problem came back....
The only solution remaining was to return the phone.... They gave me a Note3 while my Note4 is being repaired...
That's a shame for a product of that price!
:crying:

Same thing is happening with my 2 months old note4 since two weeks ago. An horizontal line 1.5cm in width about 1/3 from the bottom of the screen, became unresponsive. At reboot it works sometimes then it becomes unresponsive again. It looks like in the image I attached, the difference is that the area is horizontal, not vertical. I'm taking my note4 to the store today for warranty, hopefully they will replace it. I haven't abused the device in any way, I have a screen protector since its first day.. I really hope this isn't a serious problem that affects many users.
Just like some of you mentioned above, the pen has no issues on any area of the screen.
Cheers!

same thing happen to my note4 today. the only difference is that yours was fixed for a couple of minutes after removing the battery. my note4 wasn't fixed after that. Only S-pen works, touch screen with fingers wont work. you mentioned you're note4 is getting repaired, did they tell you what may have happened to it so that i'll get an idea of the cause..

Never purchase a device without a return / DOA policy. Not worth the hassle. If it hasn't been 30 days, you should call your credit card company or Paypal and place the amount on dispute, wait, you purchased from another market, please tell you didn't pay by cash.

I have this problem after I flash CWM recovery, before this was flashed with twrp recovery, I reflash stock rom with odin, I flash many times CWM and TWRP and I still have the problem, my warranty it's void now but I think to go at Samsung store to see if they solve my problem. This problem look like a driver for touch corrupted, if somebody find it out how to fix or have any ideea please weritte here, thanks you

I've started to have this problem as well, lower part of the left side of the screen sometimes registers touch instead of scrolling! Very annoying, tried to update recovery, tried tapping screen, doesn't help. The worst thing is I cannot reproduce the issue at will... It seems pretty random.

Unfortunately, if the phone is on Verizon, the dialing codes will be disabled.

Potential fix.
Please excuse the necropost But I came here looking for a solution from google and others may too. I found a way to solve this issue/s.
There appear to be two issues affecting this.
1. Overloading the processor.
2. Static.
If your touch input is lagging or doesn't register at all but then suddenly does a few moments later, its likely a type 1. problem. I fixed this by disabling resource intensive features such as s voice. This also improved battery life and overall performance considerably.
If touch simply doesn't work at all, but s pen works fine then the problem is more likely type 2. That being static buildup in your person. Simply touch something that can ground you and it should fix the issue. A metal tap should work. Be wary, you might even get a little zap as you discharge
