Note 3 - N9005 - Severe Slowdown/Ghost Touches - Galaxy Note 3 Q&A, Help & Troubleshooting

Anyone else had this happen to their Note 3 please ?
last week its become very very slow - even lock-screen is lagged by about 10 seconds behind your pattern press
typing anything in is very very slow - very laggy - phone is basically unusable
Seems that the capacitive bottom left button (switch apps) button might be continously polling reacting to a ghost touch - but I'm getting other strange things like volume sticks going down or up (as in will go down but then continue to try and go down permanently etc) - this latter effect might be because of the capactive buttons polling
any ideas please ?
I've tried a re-flash of BTU firmware, I've tried wiping cache and complete factory reset - so I'm assuming a hardware fault - just wondered if anyone else had had this please ?

Was the phone dropped or exposed to liquids?

Mystery input problem

My M700 (orange rom, new radio rom) is having problems with the buttons (or is it?)
Basically, I noticed things were happening without me pressing buttons, occasionally (like when Im in a phone call) it will flash up that I cannot put this call on hold (though I didnt try to)- or when I'm in GPS (TomTom) it occasionally goes back to the options screen without me pressing anything.
I also noticed that occasionally the scroll wheel wont work on the side, and if i press the memo button opposite, it goes to the "realign my screen" program (which happens when you press them both together) but then it works normally again
Finally the little directional pad at the bottom has stopped working sometimes (including the button in the middle, but not the buttons surrounding them ie ok, windows hang up, make a call etc) -
Anyway - it seems to me like either there is a software problem, or that one of the buttons is being activated continuously, possibly by dirt, which might explain the intermittent nature of the fault.
Does anybody have any similar experience?
And...
What should I do - look at potential software problems, or hardware - (Im thinking hardware) should I take it to bits and clean it?
Thanks for reading my lengthy post, and I really appreciate any help from anyone, especially from people who've had this problem and fixed it
Update (2 mins later)
Whilst examining my pda, I dropped it onto the floor, and everything started working again - I'm beginning to think that its the silver button in the middle of the direction pad that is causing the fault, as when I hold it on it has all the same effects -
So, if this is the case, does anyone have any ideas, how to clean it easily? (if it is a hardware problem that is- it lives in my pocket and get pretty dusty so it could be)

Please help my phone hates me!!

Anyone have this issue?
Whenever I have a new rom, it works great, as soon as i reboot or a low battery forces a power down, it is buggy and unresponsive upon reboot.
symptoms include:
1. multiple entries on text/numbers - ie when pressing a, it registers aaaaaaa
2. cannot swipe screen, it will open app on homescreen that it presses
3. overall, no accuracy on touchscreen.
4. overall, it really seems to effect the touchscreen and it consistently happens on reboot.
try calibrating your screen during initial setup or in keyboard settings
touchscreen issue
the only thing that works is to reset data on it from the fastboot screen. (skateboard screen)
From there, the touchscreen works, but i have to start from a new device. Really lame.
Right after the data reset, I turned the phone off and on, and it works. Seems like it only wants to happen after i put things on the device.

Touch Screen too sensitive

Has anyone else had the issue where you can press down on the screen, a tool bar or something and the screen starts to shake or the selector starts to auto select things. I get this a lot and typing is often very hard because it randomly selecting things when i am typing on the keypad.
I have seen it once when i put the phone down go through random menus, is this a fault or just normal due to sensitivity?

Hi
I've had the same problem several times with both stock rom and cooked.
I turn it off, wipe the screen and it will usually revert to working properly.
Most would say it's a fault unfortunately. Personally I've returned mine for a replacement after a 'repair' which fitted a new screen made the problem worse.
See this thread.

[Q] Problem with UN-lock screen

Sometimes the un-lock screen doesn't work ... I scroll down with my finger but the unlock screen doesn't disappear, it stay on the screen and i can "move" it up and down forever ...
the power button do nothing ... so i must remove the battery to power off my htc hd mini!!
Any other user have the same problem?
There is a "fix"? :|
Tnx a lot!
Virtual
Me too, It's appear randomly. Very annoy
I'm beginning to realize HD mini is one very buggy device.
Never had that problem, not with original ROM not with custom.
Have you tried hard reset? or flashing newer/custom ROM?
Just reset the device.
This problem occurs when you uninstall some apps which are related to phones user interface like themes or any custom lock (iPhone like lock/unlock screen) applications.
yes, it happens sometime.
This is normal issue of windows phone (like hang up issue).
soft reset will fix it or remove battery,put it back & re-start.
never met it with official ROM..
Finally, It happen when listen to the music with Music Tab for a while. It's not only lock screen problem but it's also
-Can not turn device off
-Proximity's not working
It's all happen when I play music in music tab.
my wifes mini does this all the time ! very anoying, once the screen is locked and the screen goes blank. when you press the power button to use the phone nothing happens, you have to pull the battery out everytime, she is getting very frustrated with this, so if anyone does have a solution please let me know....

S8+ Screen unresponsive, after several minutes - everything else works

Hi,
I am after some help please, preferably without reinstalling all over again (root etc).
If i leave my phone to lock after a few minutes of inactivity, the screen stops responding but everything else works:
All hardware buttons work
AOD - works, I can press notifications and the app opens, or hardpress the bottom home button to get to the home screen, but the screen wont respond after.
Fingerprint scanner - works, it bypasses the lock screen but nothing responds
DEX - phone completely responsive via keyboard and mouse
Soft reset - everything works until it has no activity again.
Safe mode - exactly the same, so seems not to be app related.
Just the screen wont respond after passing AOD but phone otherwise functional. Not dropped, no water damage - all good there.
Anyone gone through similar?
Cheers
Good lock 2018 - lock star
Interesting - after spending nearly all day playing about and deciding to post, i remembered there was a lockstar update for me this morning. I disabled the lock screen i built and the phone has been find since. I'll un-install and re-install it, and re-test should someone else have a problem with it and follow up.
Reinstalling LockStar fixed the problem. Case closed.
