i just replaced the screen on my focus n i used it all day n made some calls then all of a sudden the screen went black on a call n it hasnt come back on since. i have tried taking out the battery, plugging it into the computer, i even updated it. and still yet a have a black screen. the touch funtions still work i can use the phone unlock it select things i just have no display. please help
Screen issue? You might need to take it apart again and check the connectors...
i tried that today n still no luck
As I said, screen problem? Although new, it might be gone. Which might also indicate another issue related to the screen (some circuit overloading?)
I had an exam and removed the battery for my phone for the duration. When I put it back in, the bottom half of my screen stopped responding to touch. The screen itself is unharmed and uncracked. The S Pen still works flawlessly. However, the bottom half of the screen ("above" about 890 pixels on the Y axis) simply does not respond to normal touch. In addition, the volume buttons no longer change my notification volume. They still work for music volume, just not touch volume. When I long-press the power button, the power menu sits at the very top of the screen and has black covering the whole bottom of the screen for some reason. When I receive calls, the buttons are right at the top. Because of this, this seems to be some sort of software issue, but I have no idea what would cause it. Has anyone with more experience with Samsung devices seen this before? Multiple restarts and battery pulls have done nothing.
EDIT: In case anyone else encounters this, it had something to do with my case. I think my phone thought it was a smart cover for some reason. I enabled and disabled smart cover and then removed and replaced the case. It's working fine now.
EDIT: Never mind, that was a coincidence. The issue is DEFINITELY that the phone thinks it has a smart cover on it, but it has nothing to do with my own case.

I've had much the same problem. While the S-Pen was able to make selections that the touchscreen wouldn't, other S-Pen functions such as Air Command and being able to start an Action Memo wouldn't work. Waiting for an extended period of time (like 24 hours) and all of a sudden it started working again. However, while I was waiting, rebooting - even performing a factory reset - didn't' fix it! I just now rebooted it and it's not working again, and it's not in a case.
Where do you find the option to enable and disable Smart Cover? On the Note 2, it was (apparently) under Security / Device Administrators, but I don't find it there. The only option I could find was in Accessories / S View Cover / Automatic Unlock but changing this setting (including rebooting between settings) hasn't solved it.

Sadly, it was just coincidence that it randomly stopped happening when I enabled and disabled the auto-unlock feature with Smart Cover. My phone started doing it again and I've been unable to repair it. I went to Verizon and they wiped my phone before telling me I'll just have to get it replaced with a refurbished one. Very frustrated. Shame there aren't any AOSP based ROMs yet (like CyanogenMod)-- they'd probably fix it since the cover thing wouldn't be a feature.
Bump.
Anyone know of the APK which would handle S View Cover behavior? If we were to disable that I imagine the problem would go away. I'm still not totally sure of the origin of the issue, but it seems to come from a combination of hardware and software problems. The hardware sensor thinks I have the case on, so the software changes things around. When I call people, I get the S View Cover style call screen. If I change the toggle in accessory settings to automatically unlock the phone when opening the cover, hitting the lock button automatically unlocks the phone as though I had no lockscreen. However, when this is disabled, the lock screen is NOT in the S View Cover form-- it looks stock. This confuses me.
Any ideas from anyone else getting the issue?
Same experience
Just to add my experience as I go. This afternoon I received an error that my SMS data could not be downloaded. Upon sliding down the notifications I was unable to control much. I ripped the majority of my hair out over this.... My pen works flawlessly everywhere though. I eventually discovered it works fine on the bottom half as you described. I have to run to some appointments, but I'll touch back after I try a few things.

Maybe it was caused by the battery insertion or backplate replacement. Perhaps too much pressure or an uneven pressure damaged the circuitry, which is now loose and causing the intermittent error.
Or perhaps it was a static discharge from the battery.
Both cases seem to me to be warrenty items.

Uh oh... I'm rooted and on Verizon. There isn't a way to unroot yet is there?

I thought the only thing necessary to unroot is to flash the stock ROM. The download is linked from the de la Vega post.

I have the same issue. I ve been trying to understand why this happened but no luck. I tried everything from updating to reseting. I first noticed it when i took the battery out as well. but the problem kinda fixed it self so i thought the phone has a spaz or something. but when i removed the battery again it happened again.
I took it to the people i bought it from and all they can say is cause there were a couple of scratches on the side of the case that it may not fall under warranty...
i was pretty angry cause its only two months old and the warranty is for a year. and the problem started happening while i was overseas so its been like that for almost a month. hopefully the sales guy is just talk cause its not up to him its just his "opinion" as he put it.
Did they explain to you why this happened? or if this is a common issue?
Hope your new phone is ok
I have this problem intermittently also. Exactly as described above.

any updates on this? im having the same problem now with my tmobile version. it fell facedown and the extended battery i had it in fell out. im going to try putting an aosp rom on it when i get home from work.
Timely post! I gave up. Verizon sending me a warranty replacement to arrive today.
Sent from my SM-N900V using Tapatalk
I have the solution!
Please. Let me know it worked for you, so people that doesn´t like to post and only read can solve this problem.
The Problem:
The half bottom screen is not working. Including the back button, the option button and the home buttom. they only work if you use the S Pen. Except for the home button. The volumes button do not work either. So the Solution is this..
take off the battery while the phone is on. YES, do not turn off the telephone and the take off the battery. Just take off the battery while the phone is on. It should work. I hope this is the solution.
One more thing. Do not allow your phone to dried up the battery completly so this wont happen again. It is better to turn it off before it dries up.!
Please let me know if it worked for you! I will let you know if this problems start again and if was only an coincidence.Hopes it not!
This tough me a good lesson! never buy a Phone from not trusted retailer, it is better to pay the full price a good store. The people that sold me the phone has a crappy warrraty like if the screen it cellphone is complete off they wont allow me to use the warranty and my phone had faulty battery conecction so it was off. then I paid 100 dollars to be repaired then this problem.
Ok, guys please let us know if it worked so people start saving their phone
Just happened to mine as well
Hard reset didn't work, on the phone with support trying to request a replacement now.
Finally Solved!

I did everything u said like:
mega wipe and changing rom

I haven't gone back to refresh my memory but it seems to me that all these occurrances were caused by removing the back cover. Try removing it and the battery and firmly press on every spot with your thumb. First place the device face down on table padded with a single layer of a blanket. Remove the SIM and SD card and firmly reinsert. Press the back cover on and try it, then return it for warranty if it is still bad.

I also was faced with this issue today at the start of my morning BUT I FOUND A SOLUTION
I have a Sprint Galaxy Note 3 N900P Stock ROM/ no root, no mods/custom kernels/boots etc...
My device side effects were
The bottom half of my screen was not responding to my fingers,
When you press the Power Button, The options appeared on the top section of the screen instead of being the center
When I press the volume up/down keys, The volume would raise and lower, But the screen that pops up and shows you the volume had increased or decreased didnt show up
Only way to use device was with S Pen
Basically all the issues everyone listed, I had them.
Now my solution; if the issue is a hardware issue.
After dissembling my phone to see what each hardware part of the phone controls, I've come to the conclusion that there was an issue with my USB Dock Connector section of the phone. I uploaded a image pointing which connector controls it. I tried to just wipe and clean it up a bit because mines had some residue on the underneath of it. Then I plugged it back in and it started back to work %100. After I tried restarting it a few times and shaking the device up, it still works; Although I am still going to order a replacement USB Charging Port with flex cable just in case.
fixed.
This is the definitely the hardware problem.
most likely happen if u ever dropped ur phone to the ground ----------- and reboot ur phone some what later time. (can be days or months).
Temp Solution to this problem is...
face down your phone to the flat floor or a table, gently hit the back, strong enough to shock the devide, but not that strong to crack your screen.
one other simple way is to drop your phone to the floor, screen is facing down, from about 30 cm high from the floor.
"simply, hit your device like you used to fix your ur old TV. "
that is just a temp. GL.
So i've had my Nexus 4 for just over 2 years now. It's stuck by me through thick and thin, i think this might be the end though.
Anyway, so i picked the phone up at around 2 am this morning, it had been working perfectly all day up to this point. So i picked it up, the colours on the screen are a bit weird. I change what's on the screen and the colours remain weird, so i do the standard thing of a reboot to see if that clears it up. This is where the big issue comes in, when the phone turns on again, there's a 1 cm wide black bar on the left side of the screen. Nothing appears to affect it, but sometimes it randomly appears greyer than others.
The rest of the screen has the same weird colours as it did before i restarted, kind of muted, and moving light areas on the screen (like app icons) makes bars of lighter colour move across the screen with them.
If i didn't know that the phone hadn't been dropped i'd be saying that the screen was just broken right now. But i flashed CM12 (was on the latest PA beta) and when the phone was restarting the whole screen flashed working for a split second before going to its broken state again. This hints at the issue being software related, especially given that it initially happened with no physical damage occurring to the phone? When thinking about this, the colour issue reminds me of what happens when you installed CM11 with the wrong kernel and it looks messed up...
Anyway, I think my phone is dead, and i'm posting here in case someone has some genius idea as to what on earth killed my phone.
I'm pretty good at doing stuff with the phone, so can flash and install whatever, hindered only slightly by missing 1 cm of the recovery menu. I would take pictures, but normally i use my phone as a camera and...... If any more info would be useful then please ask!
Thanks for any help, ideas or input in advance!

I have yotaphone 2 from tinydeal germany. (I think they flash the ROM to change the language.)
The phone worked fine at first but now the e screen on the back is doing strange things, leaving images of previous pages showing through the current page. This means, for example, on the clock face the clock is faint on a grey background and as the fingers move they leave a black after-image. Pages that should be black look speckled grey. Any suggestions for cause and a fix?
Unfortunately this is how (older) EPD screens work. When updated they somtimes leave a ghost image behind. To eliminate this the screen needs to be flashed white/black/white before redrawing and with the low refresh frequency of EPD this results in a very flickering image. So there is nothing wrong with your screen, this is just how EPD screens work. See also here https://en.wikipedia.org/wiki/Electronic_paper#Disadvantages
Thanks, but this ghosting or layered imaging is much more severe. I know someone else with the same phone where black is black and whilst there is very slight ghosting of things like clock fingers it is nothing like this current phone. The phone was fine when we got it, and the layered/grey imaging has started without me doing anything. I only mentioned flashing of the ROM because Tinydeal have told me that that is what they do to change the language on these phones.
So from the Wikipedia entry and your comments I now assume that the phone should automatically flash black/white between page changes but it isn't doing it.
The ghost images don't appear if you load something like chess or sudoko onto the rear display but appear again as soon as the regular Yotapanel or Yotacover is used.
I have the same problem, but only when the white theme in the Yotahub is turned off (so the dark theme is active) or when I use the Yota Mirror. The ghosting is terrible. When I use the white theme, it looks like it should look. I am not aware of any changes I made to my phone yesterday, but in the afternoon this problem started.
Does someone know how to check if the screen is flashing/refreshing correctly and if not, how to repair this?
Update: when I put a completely black screen on the back, it is spotty. The black is not black, but dark grey, and there are many lighter spots on the screen.
Update 2: the white theme has this problem too, but less visible. The white starts as real white, but because of ghosting becomes slightly grey. With black it is much more noticeable, because black does start as dark grey.
Well this may only turn out to be a temporary fix but I went through the Yotapanel pages repeatedly and very rapidly using the bottom of the page buttons.
I got all sorts of shades of grey and multiple overlying images but then the phone suddenly showed a clear black and white page with clock.
Ringing the phone from another phone produced a clear missed call message on the back of the phone and then after a minute the clear black and white clock page came back. I am leavng the phone without looking at all the othe Yotapanels or the Yotacover for the moment in the hope that something just got out of phase in the software and the phone might now settle down to correct operation again.
I have the same problem. It has started a few days ago and it gets worse every day.
Unfrtunately the problem has returned on my phone although I was able to get back to a black screen with the clock after three page changes using the bottom left arrow. This time a missed call message came up very clearly on the back of the phone but after the missed call message cleared the whole of the back of the phone was speckled grey with a very faint clock image. One question though: is this just the phones from Tinydeal where they have apparently flashed the ROM, or is it all phones?

That's the app for Nook ereader to refresh its screen and get rid of ghosting. Works also on Yotaphone.
What always works for me to clear the screen when the ghosting annoys me is to switch to Android on the EPD screen (by holding the circle button and choosing the left option) and switch back right away using the same procedure. This always leaves me with a clean black back.
Thanks Keeper and VirtualL.
Tinydeal asked me to upload a video to demonstrate the fault, and no sooner than they did that the phone started behaving normally again!
So if it goes again the first thing I will try is that page sequence, and if it fails the App.
I have to say that these are really fantastic phones. I think that a lot of original reviewers completely overlooked the basic issue of not being able to see a phone screen in bright sunlight, but that the yotaphone overcomes this problem.
Resolved by switching the back to front screen views a couple of times. Getting the front screen to mirror on the back seems to give that hard black and white interscreen flash that clears previous images.

I don't know if you already use it but this widget makes it very easy to switch between mirror and back. Just one click on the widget.

Last week, I got a chinese version (YD206) through GearBest. I had the same problem what you mentioned. (Black was always Grey and was never black and lot of ghosting). Until yesterday, I used to think that's how the e-Ink display works so I was using White theme all the time.
After seeing your post, I tried using Nook cleaner software and it did not help. Then, I removed the screen protector which the phone came with. For the next 1 hour, I did not see any difference. I left it thinking it could be ROM issue.
But, after few hours, I noticed everything became normal. Now, the e-ink screen looks goergeous in BLACK.

This issue keeps coming back and I am not able to find a guaranteed solution to this.
Like you described, activating and deactivating Yota Mirror in quick succession clears the ghosting and makes the screen BLACK. At other times, it does not work at all.
I even try swapping to different Yota Panels, but it is a hit and miss. Is this issue specific to Chinese version of YD206?
How to solve this issue permanently?
If not possible, is there any known step which I can do to clear the ghosting?

Hey Yotaphone Users!
I finally have a solution for this problem, that I received from the Yota Phone Support:
"If you see that ghosting is amplified, try to do some steps. Try to discharge the phone completely. Then leave it discharged for long periods of time, f.e. overnight. Then charge the phone to 100%."
For me that worked perfectly!
For me the discharge-recharge didn't work at all.
Discharged untill it switched off. Turned it on again untill switched off, untill phone wouldn't start up again. So: battery was flat.
What happened was: EPD turned black. Yohoo! Happy!
But: after one night discharged, i put it on charger again. Screen switched on, and ghosting was immediately back.
Disappointed. Very disappointed.
Anyone has a different solution?

Sad to hear that.
Did you remove the screen protector from the back side as in the post #14 the user said that after removing the epd screen became normal black again?
Has anyone heard and try heating with hairdryer the EPD screen for 2 minutes (not too hot) to eliminate ghosting?
I have an international Galaxy Note 3 in a very good condition since I first bought it in 2013. I bought a new phone and placed this phone in my drawer for about 4 months, when I wanted to turn it back on, I noticed the following:
- Greenish/Yellowish tint as soon as I saw the Note 3 logo
- After booting, some white horizontal lines appear on the left side of the screen and they keep flickering
- The screen's refresh rate is so low that it shows a ghost trail behind anything that moves on it
here's a video of how it looks (copy and paste it in your browser): streamable.com/ii7bph
I don't know how or why this happened, I took good care of it and it didn't suffer from any drops or hits to cause this, could this be a hardware problem?
I've tried the following with no results:
- Disassembled the phone and cleaned the screen's ribbon connectors
- Cleared Cache and Dalvik
- Did a factory reset
- The phone was rooted and had a custom ROM installed, I tried restoring it to original Samsung firmware and still no results
Please help me...

definitely looks like a hardware(display) problem, not software. maybe it got damaged during when you stored the device or something, who knows?
you can find screen replacements online or locally if you know where to look, just make sure its specific to your device variant to prevent any incompatibilities(learned this the hard way btw)
