[Q] Display problems - Galaxy S 4 Q&A, Help & Troubleshooting

I dropped my S4 the other day and cracked the glass but it continued to work. A few days later I picked the phone up and hit the side button to bring up the display and now all I get is a flash and the screen remains black. Rebooted, pulled battery and still does the same. You can still hear emails coming in and when I get a phone call I can swipe the screen and take the call but it remains black. The only thing that lights up is the led and the menu and back button. I took it apart looking for a loose cable but saw none. Any ideas? New digitizer?

white screen of death?

aright previously my LCD screen was cracked well i got the replacement LCD screen and it works fine. BUT my problem now is that its just displaying a white screen. Nothing else. I take off the battery put it back on turn the phone on and i get a white screen no letters no nothing.
Does this mean my phone is a brick?
i still get response when i hold down the comm button it vibrates. The volume slider responds with the volume going up and down. and when i try to hard reset via holding the comm button,voicebutton,camera button and hitting the soft reset button it responds to it and resets the phone apparantly.
So i know for a fact the actual phone works..but its not displaying anything but a white screen...is there anything else i can do ?
If you have replaced the screen yourself, it may be worth trying to re-fit it again. Make sure the connectors are in pefectly, and make sure there is no dirt on them. If the pda still responds to button presses, it's fine, it's only the srcreen that's damaged/non-functional...
To see if this is the case, try tapping on the very to left of the screen, and see if you get the start menu pop. If you don't it's prolly the connector not plugged in properly, if you do, then the connector may be damaged...
ok im trying now..but how could it be the screen if the screen is giving me a perfectly white screen and its been tested to be working correctly?
sweeet i reconnected everything and it worked thanks for the recommendation dood much appreciated

Nice to see that my reccomendation worked for you. I've never replaced a colour LCD screen before, but some of the B&W ones i've replaced have had similar faults. It's the same with old cartridge games if you think about it, you used to have to blow on them ocasionally...
Modern technology may be perfect in every respect, but the manufacturing methods arn't.

Defective touch screen?

I had my evo's (003) touch screen die where the main screen didnt light up but the buttons did. I couldnt see anything on the phone but it did work and I could make calls with bluetooth etc.. SO, I took the phone into the store and they replaced the entire screen which includes the front buttons and side volume rocker etc.
HOWEVER, now the bottom buttons (home, back etc) do not work. Has anyone had this issue? Im taking it back for them to put ANOTHER screen on.. I did find this video of almost the same issue I am having:
Im wondering if other had this issue and if there might be a bad batch of replacement panels... The service tech told me I needed to hard reset to get the buttons working and I did and same issue....
Thanks....
I have had that happen before even white spots on screen and where it became unresponsive to touch locked up. Had it swapped out and the new one had the screen coming apart. Then the next one wasn't glued on right windex got on the lcd. Got my phone from Asurion and they sent me one with glue all over messed up charger port and the screen had 15 lines running str8 down the center.
I have no idea why but I believe there is a bad batch of panels still running around. Now I have a brand new 0004 evo Asurion gave me after I called and talked to them takes awhile to get through to someone. But worth the 100.
Sprint store always gave me refurbs with big issues always such as screen issues and broken volume button and camera issues.

[Help] Black screen

Hello good folks,
I would like a bit of help with sorting my phone out. As of Thursday morning (2 AM or so) my phone has a black screen. The phone switches on, the touchscreen works (I can unlock it, put it to silent, hold the power key and tap the places on screen that would normally switch it off to do just that), the volume keys work, I can receive calls, the back light works.
Everything is as it should be, but I cant see a damn thing!
I should note that this happened once before, about a month ago and a few hours later it was back to normal. Also, I have noticed over the past few months a very small black circle at the top edge of the screen, about half a centimetre in diameter.
Please help!
Kindest regards.
It's the first time I read such an issue, your screen's probably defective.
To eliminate a probable OS issue, does the bootloader appear flawlessly ?
No, nothing appears at all. The screen is completely black at all times!
Your screen is malfunctioning, I don't know what's causing it and I don't know if you can fix it yourself either.
I think you are better off sending it back, if still under warranty.
Otherwise, ... ?
This just happened to me NOW....I'm waiting hopefully it will fix itself as i hear the HD2 heals itself LOL

[Q] Odd behaviors since screen replacement

A few weeks ago I dropped my GS4 coming out of the grocery store. It hit the curb on its side right at the volume button. The screen (glass and LCD) broke. The volume button also deformed slightly. The case I had on it offered no protection around the buttons or the top and bottom. Got an Otterbox on it now.
Anyway, after weighing my options I ordered a new screen was replaced it myself. The process is pretty straight forward and only took about 20 minutes. I could probably do it in 5 if I had to do so again. Since the replacement I've noticed a few odd behaviors. It doesn't seem to charge as quickly (could be my imagination, I have no hard data to back that up.) I had it on the charger for about 6 hours last night and it only got up to 86%. It was at about 25% when I plugged it in. To be fair, last night was the first time that's happened. I was using the same charger I've been using since I got it.
Its also fully waking when I wave my hand over it to check notifications. It used to just show the screen with the notifications and time. Now, that screen comes up briefly then goes to the unlock screen.
The replacement screen is an OEM Samsung screen for the i337. The internal markings are all correct and match the broken one. Any ideas why this is happening?
Okay, the charging thing seems to have been a fluke. Haven't had an issue with it since that night. The issue with it going to the lock screen when you wave your hand over the screen persists though. It is happening every time. Also noticing that when I make a phone call from the handset (not sure if its the same when I initiate the call from Bluetooth) that the phone volume slider appears on the screen. The volume doesn't change, the slider just appears.

S6Edge+ cracked screen, wake up problems

i have a S6 Edge+ and its got a cracked screen. it has a big black spot the size of a fingertip on the right middle like something stabbed it maybe.
sometimes when i got to wake it up, phone is on and i press the power button the lights on the bottom come on, the cascade window button and the back button............but the screen does not light up. it kind of flickers and i see the permanent damaged part, a green strip down the right side of screen but does not turn on.
sometimes i have to press the power button to wake up and put to sleep 6 or 10 times for the screen to light up.
my question:
do you think this is simply from the screen being damaged.
have you seen anything like this before on a phone
do you think if i spend the money to fix the screen this issue will be fixed?

Yes.
Yes, on my son's Xperia Z5 Compact. He hadn't dropped it or damaged it in any way - just happened.

Fixed by Sony, phone is insured.
Yes, take it to Samsung store to repairing.
Ok, I have booted into safe mode and the problem does not exist. this means its a sofware issue, obviously. Here is the dilemma, I have done factory and hard resets to include the cache partition. How might i go about fixing this issue until they release a new update from android 5.1.1???
Can anybody tell me what core we use to put the touchwiz snappier, I saw one one topic but I can't find it now. We only have to put the code and the phone was so quick like the day we Unbox the phone. Thanks
