[Q] Screen Problem - Transformer TF300T Q&A, Help & Troubleshooting

hey guys, i've bought an new tf300t for me. it went extreamly good and i'm very impressed. the first day went well, I only installed a few apps, tested them until the battary was empty for the first time, so I charged it during the night (in power-off mode). The next day, as I took my new tablet and pushed the power button, a thin (1 pixel width) line appeared on the screen. It went from the left to the right edge and has benn on the screen the whole time. Nothing did work, I reseted it, made a factory reset, nothing worked
Do I really have to send it back because of the hardware malfunctino or is there any other sultion?
Thanks for every answer!!!

If you are on the latest firmware .30 and you still have this line you should exchange it for a new one.

bring it back to the store
bring it to the store were i live theirs a 14 day law and warranty shod cover it but looks like ether you can get to the recovery so you rom might have gotten mest up up

nope
i didn't even root it, nor there wasn't any custom rom... it passed out on the second day of useage.

Power button stopped working

Last couple of days i had noticed that it was taking 3 or 4 tries to get the screen on and off. Today button has gone completelt flat, its almost spring in there broke or something. My question ..is there anyway i can open it and replace the button or do i have to send it in. I had bought it from newegg and there 30 days warranty expired last week.
Power button stops working
Yes, I also had the power button stop working. And, to make matters even better, I got into CWM (or CMW or whatever) to tried to put stock OS back on and got STUCK there. No power buttton, no ability in CWM to go to Backup menu to reflash stock, and no ability to reboot from the main menu!
The power button is cheap, cheap, cheap; you may have trouble getting it fixed if you've rooted (because rooting kills the warranty) and can't reflash stock.
Very disappointed with ASUS on this issue.

30 days is the return option from newegg, then there is always the Asus warranty (you can rma it).
I would anyway try newegg first: I had the same problem with my transformer bought from amazon.fr, and they changed it even after 45 days... they sent me a new one (got it 14h after having contacted them, great service indeed).

D800 screen going absolutely crazy!

After getting a new Oneplus One phone back in July, I have not been using my D800. I have been turning it on every couple of weeks to update the CM11 nightly and the apps. The last update was about a week or so ago. After doing the update I played with the phone for a while then shut it off and stored it.
I got the phone out this morning, turned it on and all of a sudden my screen started going crazy as though it has a mind of its own. My touches almost have no effect. With the screen off sitting on the table it will on its own come on and start tapping at the status bar opening my calendar and quick toggles. It seems that most of the activity is happening at the top of my phone.
I manually entered TWRP recovery and saw that the screen problem is there too. Therefore, it would be dangerous to attempt to make any selections on screen in TWRP because there is a good chance it will select something I do not need selected!
Does this sound like a bad digitizer? My phone has never been dropped. It is in mint condition.
I would like to restore one of my stock rom nandroids but am unsure about how to do that outside of TWRP. Can I do this in download mode and adb? If so, would you mind a few general steps?
I am the second owner of the phone. The original owner purchased it outright from Best Buys about February this year. If I send it in for a warranty repair I would like to have it back as close to stock as possible.
Thanks.
EDIT: Well I managed to restore a stock rom nandroid with twrp. Problem still there. I called LG cust service and the phone is still under warranty until December. Got an RA so I will be shipping to Texas tomorrow.

S6 Pressing Back Button By It's self (Capacitive key)

I'm not sure how this is possible, but about once or twice a day, the back button on my S6 is pressed on it's own. It has happened when the device has been on the desk, I see the soft keys light up, the device vibrates like they've been touched and the app I was on went back, all while I was not even touching the device.
It's happened mostly when I'm holding the phone but not even close to touching the buttons, and once it happened and pressed the back button about 10 times in a row while I watched it.
The phone is completely undamaged, perfect condition, never touched water, not dirty at all, buttons are 100% clean. Happens while it's charging or on battery.
Has anyone else experienced this?
(My device was repaired by Samsung for a different issue, motherboard replaced, this only started happening after the repair)
i have, started like yours random. then it started happening more and more so when i was at the store waiting for someone i decided to factory reset ( factory reset twice while at the store) but it got worse. couldn't even get passed initial setup the phone just kept spamming back button so i just kept going back. luckily i already ordered a replacement s6 from tmobile since i was having some other issue with the phone. sadly the replacement s6 took over 7 days to get here. shipped through UPS and got to hawaii then for some reason UPS gave it to USPS for delivery. kinda sad that i ordered screen protectors 2 days after i ordered replacement phone and the screen protectors got here 4 days later through USPS. but other than that my NEW ( we all know its refurbished) galaxy s6 so far has no issues. even the no audio on calls is fixed.
also if you are going to order a replacement, be sure to let them know you have a GALAXY S6 and the date it was released. i say this because the 2 tmobile reps i talked to kept asking questions they say it was for them to determine if my galaxy s6 that was what 2 almost 3 months old at the time was still under warranty
My s6 was showing the same issue with the stuck back button.
It started randomly but than it went crazy and stuck. I wasn't even able to use it.
But 1 factory reset fixed it.
But yesterday the random stuck back button started again when the phone was on my desk and it was really hot (weather was hot as well as the phone). I turned it off for a while and apparently the issue stopped.
I'm not sure it's temperature, firmware, whatever related but I really don't want to factory reset it again.
No solution here, but it is happening to me as well
Solved
Hi i had the same problem aswell , i bought samsung s6 in Pakistan, after the update the back button kept pressing ghostly, i went to local samsung repair shop and the assistant reset something from the setting and then it was fine, i even asked him what you did and how you did? but he said it is secret lol very stupid. i could have post the solution if i know it, but i think it is very easy and something to do with setting. i am sure it is not hard/soft reset. i will post this on other forums to help other people.
thanks
having this problem with my phone too, i cant even get it to stay on the settings screen long enough to back up my stuff
edit: well i think i solved it. i tried clearing the cache, didnt work. then i did a hard reset, didnt work. then i went back and cleared the cache and did a hard reset at the same time and it seems to have worked.
+1 same problem. It happens mainly when the phone is on the move. Funny thing it happened 3-4 times while taking the metro (go figure) with the data on. Usually when I turn off the data, it reduces the amount of back press.
Normal reset doesn't solve the problem. It stops after a while, probably when the phone cools down. I can't seem to reproduce it, but I believe it has something to do with the data on.
I don't really want to factory reset so I'm going to write to samsung directly as the phone is brand new.
i am having same issue too.

Did anyone try loading a custom rom and got it fixed ?
I've had that issue with my first one. Took it back ASAP as it was DOA. Got a brand new one 3 days later as they didn't have any in stock. This one doesn't have any problems. Don't worry to mutch about it. Get it exchanged.
It is a hardware defect: When the phone turns up power to the radio to strengthen the connection, it can cause Electronic Noise to leak over the connection into the capacitive buttons (due to poorly insulated shielding tape), causing the phone to think the buttons were pressed. That's why you notice the problem more when roaming -- the device needs to be repaired/replaced.
I have the exact same problem...did anyone contact the manufacturer and got a response on the matter?
I believe it may be an app setting messing with the system settings. My device did it once and wouldnt allow me to use my device. After factory reset it made it worse so i used twrp and wiped everything but my modem and flashed my stock firmware and it stopped and hasnt done it since

Hum that's interesting, thanks for your precious input on this.
I did contact Samsung who asked me to do a factory reset. It didn't change anything.
They redirected me to a Samsung office in Paris, not for repair but for a deeper factory reset... (not sure what they are talking about), but I haven't been there since due to lack of time.
However, I didn't experience the problem since the last update FXXU3QOKN so I'm keeping an eye on it.
Following "faiding's" comment, I'll probably pay them a visit for a replacement.
working "workaround"
workaround:
lower the speaker volume to ~75% in all settings (Media, ringtone, system, notifications, etc...)
Whats going on? why is it working?
some posts ago someone (user called "faiding") mentioned something about EMC leak, or at least he meant to, by mentioning a faulty insulation.
with that in mind i did some testing and found out that the closes radiating component it the speaker... and once you lower its emissions even thought the faulty insulation, the EMC leak is sufficiently low and the 'capacity short' is avoided.
Note: depending on how 'faulty' is your insulation (it varies from one phone to another depending on production line assembly) lower the volume until the issue stops accruing.
not full-proof but working
What worked for me is turn power saving on
possible fix
might be a coincidence, but this worked for me:
(I am a new user so i cant post a link but here is what you should do)
1. enter YOUTUBE
2. find this video: "Samsung Galaxy S6 Touch Screen Sensitivity Fix"
worked like magic for me
Repair tech
It is true that if your in the US and your phone has no damage or any water damage to void your warranty even if you bought it from someone else, u can register the phone at samsung website and then request a repair. It will still have a warranty.
But as I am a Cellphone tech, sometimes I rebuild phones. A s6 came into my shop and i once rebuilt it and worked for a while before doing the phantom touches on task and back keys. So when i pulled the screen up a little off the touch keys, it would stop. I gave up after a while trying to figure it out as i had more things to work on. Back in December i decided to rebuild it again, new screen, new battery, new frame and new back. Turned it into a gold s6 to try and sell it again. Sold it couple days ago, and it came back the next day doing the same thing. So got bored tonight and started to take it back apart. Figured i would try one more thing, replaced the charging port (which is also the soft touch keys) to see if that would resolve it. So far its not wigging out but im letting it sit here and try using it from time to time, with wifi on and a simcard installed. So far its not going crazy, but I will let everyone know if it fixes it or not. As for the "Youtube thing" I tried that, did not resolve. Im guessing its a defective soft touch keys/charging port.
I would not recommend this repair unless your phone is out or voided of warranty.

Hi dslayer83,
I've the same problem with my S6
Could you solved the problem replacing the charging port?
It would be very important to me knowing how to repair the phone because I buyed it abroad. In my country Samsung does not cover warranty.
Up with this thread!
I had an S6 since January.. initially the problem was very random, maybe 1 or 2 times per day, sometimes would go crazy for a while
Then i had some time with no defect at all (a couple of weeks?) without doing nothing
This past week, the phone was feeling like the MENU button (what menu as in this phone there isn't any?) and that was very weird!
Today, it simply went completely crazy, and now is completely unusable... i can't actually swtich it off as the back key is pressed so quickly i don't have the chance of doing nothing!
EDIT: Managed to reboot and wipe cache... now it is useable, but still hits the button from time to time
Update... went unuseable again today.... factory resetting now...
If it works, shall we suspect is something software related?
Update: Not working... it started giving the phantom touches just after the factory reset then suddenly stopped
Worked fine for few hours, then started craza again
Now i have done a wipe and factory reset again, and still unuseable

Odd problem, broken home button?

Hi all,
Long story, but the quick version is my home button rarely does anything any more and the screen wakes up by itself from being asleep after anywhere from 3 seconds to 12 seconds.
Now for the long version:
Non-rooted Galaxy S6, by the way. I did a factory reset last week, just because things were getting sluggish. It went well, things were back to speed, and I reinstalled the essentials I wanted. Last night I noticed my phone kept waking itself up over and over again. Then I noticed the home button wasn't doing anything. I rebooted it and it didn't change a thing. After a little more time, the power button also stopped responding. I couldn't even do an emergency reboot with those two buttons disabled. I even tried sticking it in the freezer for a few minutes to see if it was too hot. Google told me about the on screen menu thing to emulate the softkeys so I was able to use that to get around and do reboots.
I hadn't installed any new apps in the last 24 hours, but what the heck, I did another factory reset. I had the option to restore all the apps and settings from 1 day ago, so I chose that. The problem still was there. Dang it, I thought I should not have restored those apps, so I did another reset, this time a totally clean one. The problem not only still happened after the reset, it was doing it during the reset, if the screen went to sleep during a step in the factory reset, the glitch would wake it back up in a few seconds.
I decided last night to just turn it off and charge it fully and hit the Sprint store in the morning. Oddly while charging with the phone powered off, the green battery display would go off and on the whole time it charged.
In the morning I turned the phone on....and NO problems. (of course) For 2 hours not one glitch. So just before leaving for work it starts happening again. Another factory reset at work and a system update from Samsung and still, the problems are there.
I'm just thinking I'll hit the Sprint store tomorrow and swap it out for a new one...but I thought I would tap you guys for any info if you had any.
Thanks in advance, Larry
Sounds like your phone got wet. Factory reset over and over again will not fix this problem ha
Hi,
It seems like a problem with the hardware itself. So yeah, factory resetting all times won't help. Go get a new one .
All the best,
~Lord

Thanks for the ideas, I tried the dialer thing, thereassaad, but it didn't help. It does sound like water damage, but there is no way. I've never dropped it or been near any water. I'm heading to the Sprint store tomorrow, too busy today. I'll let you folks know how it went tomorrow night.
Just FYI, they replaced the screen saying that fixed the home button not responding and the screen waking itself up, but said I probably shouldn't restore with my google account, since it's likely corrupting my system... Huh? I said. They said the hardware was fixed, but I should create a new google account. I said no way. I said what does having just my contacts imported (no apps) have to do with hardware failure. I said, open up a new phone and lets put my google account on it and see if it breaks the new phone, they said no.
In the store we added my google account to my "fixed" phone with the new screen and all and it messed up again. They said, never mind, we'll replace it, and it should be there this Tuesday.
I didn't ask if it would be a refurb, but I really don't care as long as it works.
So that's my story. So far.
They swapped it out for a new phone, refurb likely, but I'm not sure how to find that out. (not that I care too much) I'm loving the new phone, it's like unboxing day again. No cost out of pocket for me too, which is nice.

Nokia 7 plus major issue

Hi everyone,
I recently got a Nokia 7 plus (5 months ago) on contract.
Last week, I used it in the morning to make a call, and, in the afternoon, when I went to use it, I found it frozen on a white screen with download mode in black, in the top right corner, and android one with a multi coloured bar below it.
Now, the phone will NOT switch off, switching off results in the phone instantly switching back on to the same screen....
I have tried, unsuccessfully, several times, to perform a hard reset, but to no avail, it simply returns to the same screen.
Even after letting the battery run totally flat and re charging, it comes back to the same.....
I went to the E E shop, (network provider), I got it from, they said as it appears to be a Nokia software problem, and still under warranty, I should send the phone directly to Nokia for repair...However, I have my wedding and honeymoon pictures on the phone which are irreplaceable and I know Nokia will reset the phone, so wiping all the data etc....I have the phone booked for delivery to Nokia, but thought I would ask here first, to see if any of you have come across this before to this extent, and have a solution?
Cheers
Pete
