SO, for over two weeks now I have been battling this on and off again issue where (in drawing apps especially) the screen would take input just fine, then later in the day when using Swype it would only accept a few letters and then stop. Or it would add random letters and spaces. In drawing apps the lines I know were drawn straight would show on the screen as having EKG looking spikes. I uniinstalled/re-installed Swype, each drawing app, I tried kernel switches, modem flashes, and even nandroid restores. Each time within a day the same issue returns.
In the wee hours of this morning I was about to do a complete wipe and reflash/restore and it occurred to me to try cleaning the screen with an isopropyl alcohol swab instead of my normal cleaning with glass cleaner. Low and behold, screen problem was immediately gone. I have tested everything I had problems with before works fine now.
When I was searching for solutions to this before, I found nothing at all so I thought I would post this suggestion for anyone having a similar problem.
Yeah, I'm surprised how few people understand what dirt and water will do to your screen. I frequently hit the screen with a drop of water and make it go crazy. Just gotta turn off the screen (not the phone), wipe the screen clean, then turn the screen back on. Good as new. Just a quirk of capacitive touch screens.
I was surprised that this fixed my problem..I am religious about cleaning and keeping clean my devices. I guess even glass cleaner can build up or miss something.
Correction- I have officially found and resolved the cause. I had my oem charger and cable plugged into an extension cord from the outlet. When plugged in I would get the screen input problems, and they immediately went away when I unplugged it. Plugged it right back in, problems. Unplugged, no problems. Rinse, lather, repeat. When I moved the charger directly to the outlet, all seems okay, no problems after several hours. I assume that it was either a grounding or voltage issue from the use of the extension cord in the middle.

Yesterday at work my boat caught on fire (serving with the Coast Guard atm) and while fighting the fire I got wet. I didn't have time to empty my pockets, and as such my phone got wet. It wasn't soaked to the point where water was dripping out of it, just the outside was damp. When I got home, I took it apart as much as I could and set it out to dry.
This morning I put it back together after checked for any water (there was none) and plugged it in, then turned it on. It booted up fine, I was able to send/receive text messages, make a phone call, and tether it to my laptop. The only problem I found was the hang-up button was constantly light, and the button itself didn't work. About an hour later I was talking to my roommate about the fire, and told him how my phone had gotten a little wet but seemed to be working OK, save for the one button. As if on cue, when I pointed and looked at it, the screen seemed to shift a little, then stopped showing the Today page and just showed a dark blue plaid pattern.
Now, about 3 hours later, the screen doesn't show anything at all. The phone is still working, hence why I am able to tether it, except I'm afraid to do anything with it in case I can't tether it again. When I hit the power button that would normally turn the screen on, all the buttons along the bottom light up, but the screen just shows a very feint, dark blue color. No plaid anymore.
Is there something I can try to do to fix this? I had thought about pulling apart even further and hope that re-seating something might help, but I don't want to completely screw it up.
A friend of mine once dumped her phone into a puddle, it wasn't a fuze, but a phone is a phone...lol. The screen stopped working, it would flicker every now and again, and you could see that the phone itself still worked, just not the screen even when it was aired out. She buried it in a bowl of dry rice and left it overnight, apparently the rice absorbed the excess moisture in the phone and it works flawlessly now. I don't know if this will work for you, but it's apparently a common fix for moisture damage as telling this story a lot of people have told me they have done the same thing and it has worked.
Quick update, I just opened the keyboard, just playing around with it in the hopes of getting something... and I did. If I open the keyboard with some force (flicking it open hard) the screen shows up perfectly for about a second, then fades to red then back to blue. So all is not lost, but maybe a bad connection somewhere?
*edit*
Just did it again (closed the keyboard pretty hard) and the screen is back to normal. Touch screen is working normally, and hasn't faded after about a minute. I'll keep you updated. I guess the good old method of beating things into submission still works like a charm.
Sometimes a good ole WACK does some good. Few years back my sister called me, her new computer would just beep when turned on. I told her to give it a good wack and turn it back on. Did the trick. Next time was up there, pulled it apart and the video card wasn't quite seated.
I got my Xoom (WiFi) yesterday... already noticing some weird touchscreen behaviour.
It seems to me that whenever the Xoom is laid down flat, there's a chance that the device will stop responding to touch presses properly. Instead of being able to press-and-swipe, it acts like I tapped the screen (eg, pressed my finger on the screen and then lifted it straight back off) or worse, it causes a screen press in completely the wrong position. When it starts happening, it keeps on happening, but picking the Xoom up and holding it vertical seems to fix the problem.
Half the time it seems fine laid down though, so I'm not sure if it's just coincidence that it stops working at the same time I put it down flat or not, or that maybe picking it up means my hand is in contact with the back of the screen and this somehow changes some sort of electrical variable in my hands that affects the touchscreen operation.
Anyone else seen the same issue? I'm thinking I may need to take it back but want to see if anyone else has experienced anything similar.
Chris.
ok.. judging by the lack of response on this, I may either be on my own or it's just something that nobody is noticing. I've been testing it a bit more - I wrote an app which can show each touch point on the screen so I can see how the screen press/drag is working. This is what I've found.
Holding the tablet upright, screen presses and movements are fine, however I've noticed that if I hold my fingers in the same place for a while, the touch points will prematurely end.
If I put the Xoom down on the couch, there is a strong likelihood that the touchscreen will become incredibly unresponsive. I have had it regularly show up phantom presses where touching one point of the screen makes it appear as if I have also pressed another point of the screen. I also cannot drag my fingers across the screen - the touch points stay where they are until I take my fingers off the screen completely, or they just disappear right away as if I tapped the screen.
When this happens, if I touch the side of the case with either a free finger or my other hand, the touchscreen starts working perfectly! Seriously! I'm not kidding, I've been messing with this thing almost non-stop for the past coulpe of days and it is consistently doing this. So - couch + little finger on side of case = working touchscreen. couch but no contact with metal case = malfunctioning touchscreen.
If I have the Xoom in Motorola's case, it seems to work fine. If I put it on a table, it's a bit buggy but generally works better than on the couch. Any sort of material seems to send it regularly into crazy mode. The only time I've noticed it doesn't do this is if I'm in contact with the device immediately before putting it down and then remain in contact with the screen.
Could some sort of static charge cause this? Is it possible that me touching the back of the case is effectively allowing it to 'conduct' electricity properly on the touch screen? I'm not all that familiar with how capacitative screens work other than I assume they measure capacitance from your fingers. Maybe a static charge could throw it off. Or maybe I have weird fingers.
Anyway, I'm pretty close to taking the Xoom back now. Just trying to figure out if it's actually faulty or whether they're all like it by 'design'.
sorry
need to post to remove my limitations sorry again
This could be a loose touch controller cable. Someone had similar problems and posted a how to fix this, search for it.
It happens with me too, it's incredible annoying when you are developing and the tablet is on your table for debugging..
Did you find how to fix it?
I have a serious unresponsive issue on my Xoom when charging. I've tried several different chargers, (all from Motorola) with no luck. Unfortunately all the ones I tried where at my house so I'm not sure if its a wiring issue in my house.
I also have a similar problem on my Droid Razr so I'm starting to think its definitely the wiring.
Anyone know about this issue or have any recommendations?

Thats weird.. i owned xoom n droid razr too but i dun have any iissue
It could be a wiring issue (try another house, I guess), but a lot of devices are like that where the touch screen stops being as responsive when it's on a wall charger.
Hi,
My Note Pro 12.2 P900 64gb is now stuck on the samsung screen of booting up and I am wondering if anyone can help me figure out what to do next.
I was experiencing the flickering issue for the last two weeks which got progressively worse and eventually caused random rebooting. One time last week it started booting slower and then it wiped out some widgets on my start screen and the apps in touchwiz but most everything else was OK. Then yesterday it would not boot up past the samsung screen. It charges up OK, and I can get to Odin where it asks if I want to load another operating system by holding power and vol up. But unless it is plugged in, just holding power off puts it in a boot loop.
The other part is if it is stuck and I hold power off it usually vibrates twice before boot looping.
I rooted the tablet when I got it, but still run stock touchwiz, I just needed some rooted apps namely LMT pie controls.
Can anyone please point me towards what to do next. Thank you very much for your help.
I guess wiping data and factory reset is your only solution right now
I shall warn you you could lose your data so I hope you already have a backup!
And also I've read that lollipop fixed flickering issue in p900 devices
I hope everything goes well for you
Good luck
hey there, you are not the only one, check this post. it seems is somethig related to battery issues

When power on, try pressing on the back, near the center with your hand. to see if it can boot normally,
Keep pressing while power on. if it works I will tell you what causing this problem.

here you can look by the minute 2:30 where the connector is located, basically under the samsung logo. I'm not doing tests yet because i have a busy day ahead
Thank you all for the responses. Holding down the back while powering on does not help. I do have the flickering thing and that started leading up to this. Lay night I took it the battery and disconnected it for a half hour and that did not help. Looking at the connections with a 20x hand lens did not reveal any cracks.
I don't remember how to wipe the data off the device, I got it right when it came out rooted it with cf root and never got around to twrp. All I wanted was LMT and Xposed. I never even updated the OS.
If anyone can help walk me through this to get it running again I'll send you a green poetic skin used once or a white well used GumDrop hideaway case I tested for work. I just would like to get this running instead of needing to purchase a new one.
Thank you again. Sincerely.
Flickering screen is caused by cracked battery connector which cannot be seen under magnified glass. Re solder will fix it, trust me I did fix some of them

So resolder the 6 posts connecting the battery connector to the motherboard? Is there anything special I need to do that, just my soldering iron with a fine tip and solder? Anything special I need about the solder or do I need a wik or anything? The last time I did any soldering work was about 25 years ago.
Also will this fix the bootlooping and hanging on booting up at the Samsung word on the screen? If it is not going to fix that problem, maybe I should look at something else first.
Thank you very much again for your help.
Sincerely

First, pressing the battery connector help your tablet to boot is a confirmation of cracked battery connector solders. 90% flickering problem is from cracked battery connector. 10% is bad battery. You should fix the battery connector first as it's major defect seen in many Samsung tablets. Re solder is simple, apply flux, then heat these pins and add more solders as possible to secure these pins. Even new main board, this connector will crack just after 3 or 4 months depending how you use your tablet, especially with who using it on their laps. The main board sits on a flexible LCD and only 3 screws to hold it to the frame at 2 speakers. You don't need to remove the main board, just disconnect your battery and re solder the connector from the top.
Be careful as this connector is very close to other components. Trust me, this re work will fix this problem as I have seen in some cases, battery jumps up from 8% to 45% after the re work, other cases pressing the battery connector help the tablet to boot or stop flickering.
This person applied the fix and succeed.

I have the Note Pro 12.2 and I had this same screen flickering issue. It would start to flicker at first around the 38% mark. I did research online and found this thread and many others. I tried the software fixes like the enabling of Developer Mode and screen brightness and other tries, but to no avail. When I pressed on the back of the tablet, the screen flickering would stop but then shortly return. So I saw the fix of trying to raise the motherboard which worked for about 2 weeks, then the screen flickering did return. It would then start to flicker around the 58% battery level mark and when it got down to around 26%, the tablet would shut down. When I plugged it in, it would show battery level of 0%, then quickly jump back up to the 26% mark when it shut itself down. So then by this time, I saw more of this thread and now was shown the soldering of the battery connectors. I had soldering equipment, but it was too large for this repair as these 6 pins are very close together. So I went to the hobby shop and purchased new equipment for about $30 with a smaller pin to be able to do this. Now, I am not an electronics guy and my past experience was replacing two bad capacitors on my Plasma TV when it went bad. That was the extent of my experience to date. So I opened up the back of my tablet and soldered the 6 pins again and the screen flickering has not returned. I am on my 5th battery cycle from 100% all the way down to 2% and the screen flickering and shutting itself down has not returned. Some people have said an electronics guy will do this for you for around $30. Well, I spent the $30 and did it myself. I want to thank the people for posting the solutions here as the soldering worked for me.
And from this post, a confirmation that repair center will do the same thing to fix flickering , auto reboot, auto shut down.....etc...all problems caused by cracked battery connector ( Connector Header ):

Ok I'll try to resolder it this weekend and report back. I think that my pertinent problem is that I have both the battery issue AND another problem that the tablet won't boot up at all but I will try the battery fix first and see what happens. Then I will report back.
Thank you very much for your suggestions.
Your feedback is very important as I see many " Hit and Run " users, they get the solution they need but never post back. Your first priority is fixing the battery connector, then next is the battery if problem persists.
This is a hardware defect I have seen in many Samsung tablets: battery capacity fluctuation, quick discharge, auto reboot, auto shutdown.......all come from battery connector . Read the threat Flickering Screen you'll see others try all solutions but never work because they don't know this is a hardware problem coming from this tiny connector.
Hello, ladies and gentlemen (and those inbetween, too)!
I will try to keep this as short as possible. If you want less details, tl;dr section at the end. EDIT: i.... didn't quite think this through
My girlfriend has an Xperia Z3 which she bought from a random seller from Germany (am UK residents). Everything about the phone was great, it was brand-new albeit it has been, apparently, been the display device; but other than that it worked perfectly. We even tested out the waterproofness right after setting up the device and charging it up to see if it works. Back then, it did.
Now, this friday (frikkin' Friday the 13th) she had some sort of an art project going on, which she wanted to do underwater. She does have a GoPro for it, but for some sample shots before finishing out, she decided she could just as well use her Xperia. Now, I was sleeping at the moment so I did not get to witness how she did it, but she assures me she closed the flaps extra carefully. However, after she tried submersing it into water, the screen started blinking randomly, as if there is some problem with LCD matrix of some sorts.
We put the Xperia into a bowl of rice and left it that way overnight. After turning the phone back on, the screen showed first "Sony Xperia" logo, then completely went blank. Just a random look-around on the Internet showed me that for extra help it would be best if you take your water-exposed phone and leave it upside-down while it is drying out. I was hopeless, but I didn't want to disappoint her so I said it would work. I was sure it would work since at times, when turning the phone on, some images did work out (like the charging icon when it's turned off and charging) so most probably the phone is not damaged yet, its just still exposed to water.
Next day, after leaving it just standing there upside down, the screen worked as normal, and normal touch functionality returned as well. Not for long however.
My final hurdle is this: When you turn on the phone (after being in vertical upside-down position) and hold it properly (as in, again, vertically, but upright-down) , the touch functions work very well. For a couple of minutes. After that the touch functionality artifacts (faulty touch detection, ultrahigh sensitivity etc) return. It appears that the water is still there somewhere, and as you hold the phone correctly, it goes down back a bit and impairs functionality.
Now, the question is: What can I do to completely remove the water from the device, seeing as keeping it in rice for 2 days did not remove the impairments from internal water exposure entirely?
So far I've tried only rice. Was bad call, but I did not think of anything better and used a bit of hairdryer at the very beginning of the issue, and yes, I now know that it was a stupid idea.
I think I will leave it in one-two more days upside-down in rice and see how it goes from there. Before turning on, I also thought about using the vacuum cleaner method of attempting to suck the water out of it through available holes.
Any other suggestions, tips and ideas? Would seriously want for things to go back to normal, considering now I do not have a phone (gave mine to girlfriend in place of her ill Xperia).
Thanks for your attention and I hope your devices stay healthy and safe!
tl;dr exposed Xperia Z3 to water with problems, turns out the damage was reversible and everything works well so far but touch functionality is faulty, still water stuck inside the phone that impairs touch screen, tried drying it by leaving in rice, gonna leave in rice for a day or two more and use vacuum cleaner on the holes right after, anything else that I could do?
So i've been having a lot of issues with my N5 lately, mostly small stuff like general slowness, poor battery life, not surprising on an almost 3 year old phone. I also lose cell service way too frequently (not an issue with my carryer, all my friends are on the same network and are fine). Camera won't focus anymore (though im pretty sure this was my fault, probably broke it while taking it apart). I'm pretty sure the battery connector on my motherboard is damaged. I've had many problems with the battery reading its temperature as -30 C (battery heath "cold"), i've replaced the battery 4 times now and i still get that problem every now and then. Pushing on the connector fixes it temporarily, so im pretty sure some pin is bent slightly out of place and i don't know how to fix that. It recently started having this issue where just moving or bumping the phone the wrong way would cause the phone to shut off. Probably an issue with the battery connector again. I tried fiddling with it but it didn't do much.
The other day i turned it on and the LCD was backlit, but black except for one single vertical white line. Rebooted and it looked normal. Few hours later i got really pissed off with it for shutting off in the middle of an important text and threw it at the wall (not the best idea i know). Screen was already cracked so i didn't really care. Ever since then the LCD has been a real pain in the ass. i can turn the phone on but there's nothing on the screen. Ii get haptic feedback when the Google logo would up, and the notification LED is flashing like i have a message. The backlight is on and pushing hard on the cable connecting the motherboard to the daughter board i can see it start to turn on, (Google logo, few seconds of boot animation) but then back to black (while still backlit).
I can post photos if it would help diagnose/fix this, my phone is my main camera and i don't want to bother anyone if i don't have to.
Anyone know any tricks that might squeeze another mouth out of this dying phone? Any response is appreciated, Thanks!
The issues could have been related to the power button or physical internal damage. My suggestion: replace the screen with a cheap 3rd party screen if the internal components are still working. This will give you more time with your existing phone and allow you to have a working backup.
