Screen Flickering and banding - ZenFone 2 Q&A, Help & Troubleshooting

As I destroyed the original LCD I replaced the screen with a cheap one from AliExpress (it costs me 25$) .
The original LCD had the same Issues:
-Screen flickering sometimes on dark backgrounds
-Screen banding
(sometimes)
I also have to mention that the screen cable is slightly folded as it was too long to reach the motherboard,
but correct me if I am wrong I don't think this is a screen issue anymore...
! UPDATE!
I've discovered that when a shade of gray and white is shown screen flickers on those shade's

I have that problem too. I have a new screen coming. I find the more I use the phone the better it is. If it sits unused. Like over night it gets worse. I let one of those pixel fixer apps run overnight. That helps some. It's only when black color hits a certain spot on the screen.

On thing to note is that the replacement hasn't got gorilla Glass protection so you definitely gonna need a screen protector.
Also I found the battery removal process a bit harder than I expected.
Try not to pry it out as it's very easy to puncture , there's a pull tab tape underneath the battery cable. It would be tricky at first but once you get it pull it away from the phone and keep it as flat and wide as possible.

I followed these two guide's:

My new screen goes flickering again, but after I keep it off for about a week (while adapting to my Redmi 3), I found that the flickering stop, for now.

Hey bru, here is a temporary solution. Pls download in playstore. Search overlay-float everywhere.
Use it to make a dummy overlay. Then you turn its color to white and place it at the boundary of flickering screen. The place where your normal screen ends and flickering starts, right at that place put the white overlay. I got this idea by observing that the flickering finishes if the screen turns white, but its just the area where flickering is happening that matters. keep that white at all times and flickering wont happen. This overlay app allows you to do that. I hope this will help you, too. ?
credit where i got the idea about this app.

Replaced the screen. Success! So far everything is good.

HTC ONE X screen ripple

Hi all.
I returned my black HOX last week because of the screen ripple thing (when you run your finger down the sides of the screen) also the screen seemed to be a tad loose just like so many people have reported on here. So phones4U sent me a white one, I have received it and its worse than the black one now I don't even have to apply any pressure to get the screen ripple. What should I do? should I just put up with the fault or should I change to another phone s3 etc.
Cheers eze

Return it and tell them its a known issue (they should know)
ask for a tested device or enforce a newer batch
SH248 on awards are good
latest SH25 and HT25 seems good
loose screen is a known defect, slight screen ripple on outer edges pressure is normal unless its acting badly

This one is serial SH24, I have literally just had the screen flicker now to, so this phones is defo a faulty one. So the slight screen ripple is normal, I would say my old black one was normal because you had to apply a bit of pressure for the ripple to appear but this white one aint normal. Anyway I have just got of the phone with phones4u and I have managed to arrange to do an exchange in store.

SH23SW, no ripple.
normal is under bit if pressure
I've had two SH25's.
First one had no screen ripple at all but the screen was loose in left bottom corner. I could feel it moving, clicking etc. The backlight was also bleeding from that corner. I returned it and the second one has screen ripple everywhere with light pressure, has a dead pixel and the screen is loose on both sides.
I'm waiting for this one to be replaced. Beginning to wish I wasn't so fussy with the 1st one.
Every HOX will do it under pressure but it shouldn't do it if pressed lightly mines does it but I don't really care as I ain't going to rub sides with a dark screen??

you second hox was defected due to the extra ripple and the first hox was defected due to screen loose
you should expect a defectless hox where the screen is rock rigid and fit on all sides and only slight ripple under pressure to the outside edges
I know, going to hold out for a perfect one now.
On this one you can see a small red light in the top left behind the screen when you are on a call, is this normal? I didn't notice it on the last one.

I dont think he means that, I had that on my original one its the notification led bleeding through the side of the screen and the case, caused by the screen not being glued correctly.
HT25 here and ripples do occur in the middle of the screen with very light pressure. when i press "send" button on SMS app i get a ripple in the middle of the screen. WTF????
I am rooted at this point and not sure if I should screw around with it. What do you guys think?

Broke my LCD, what are my options?

So I have literally no idea how this happened. I'm guessing I stepped on my phone while I was cleaning my room but the LCD had black and white stripes going up and down when I turned the phone on, and after a reboot my screen is completely black with a diagonal white stripe on one corner. However, the digitizer works fine and the backlight works. I'm able to answer calls and use the capacitive buttons. I found a replacement LCD through repairsuniverse.com for $35, and I'm wondering if this is my best options. Any G2/DZ users been through the same experience? Many thanks in advance.
I've done it before. It's not that bad. Make sure you do it slowly in a well lit area with clean hands. You've seen the video right? Make sure you have the phone separator tool or thick guitar picks

[Q] Pink Smudge

Hello xda
can you please help me?
A weird pink smudge (size of a finger tip) appeared on my 2weeks old galaxy note 2. Im not using a screen protector but it is in a great condition, few really light scratches, screen is perfectly clean. Smudge is visible on white/yellowish background, but doesnt dissappear on other colours (gray etc,) and is noticable. Ive made a screenshot on the phone, and the smudge isnt visible on the screenshot, just on the screen. Touch is working fine. Other colours are also working on the pink smudge, like when im using Note app, i can paint some stuff , when i paint the smudge with black it isnt visible, but when i paint white its visible. Its placed in the middle left side of the screen. I dont know the cause of it. Can i fix it somehow?
It sounds like the AMOLED panel is messed up... can you take a picture with a camera to show us what it looks like exactly?
It's only 2 weeks old, take it back.
dead pixel

Faulty! Get it replaced! ASAP!
take it back, but before that just remove the screen protector and see if there is any difference.
Some wet application protectors tend to leave behind pink stain in some areas sometimes. But this does look more like a screen issue. But just check before submitting phone to samsung for repairs.

i have no screen protector.
Also a new question could this be made by poking/knocking the screen with a tip of a finger? I heard the screen is really though but I really don't know the cause. And if so, does warranty cover such thing?
it's a stupid question. But I noticed the smudge sometime after a random dude was poking my screen with his finger tips get my attention.
Sent from my GT-N7100 using xda app-developers app
Take it back, under normal use (and even in cases where you'd tap rather hard on the screen) you should never see this... it almost looks like pressure damage to the AMOLED display panel, maybe it's not seated properly. Either way, you should definitely seek replacement or repair ASAP.

Q: Circle/Spot in bottom section. Sensor?

When I was wiping down the screen nicely before applying a screen protector I noticed in the bottom section, not where there is screen, theres a slight mark. As if something is behind it.
Its directly in the middle, aligned with the center of the Home softbutton, about and inch or so below the home button.
Seems like maybe a sensor, but I dont know. Anyone else notice this?

It's a white notification light. Wait until you get an email and it will flash about every 10 seconds. You can turn it off under settings/ display.

LG G3 camera lens scratches?

Hi all.
I've received my brand new LG G3 32GB international D855. Awesome phone, really.
Anyway I've encountered some hardware related problems:
1st I've noticed that top and bottom of the screen are brighter, but I think it's due to the LCD technology itself (used amoleds in the last 3 years so a different technology with different and, imho, worse problems).
2nd, and the topic of this question, my camera is showing few very light scratches on the back lens. From my tests, fortunately, I realized that they're not visible in any kind of photo.
I used a cover and a screen protector since I unboxed.
My question is: is anyone experiencing similar issue? Is the lens so easy to damage?
I'm pretty worried because my Note 3 never showed a scratch in 7 months used without any kind of protection...
Sent from my LG-D855 using XDA Premium 4 mobile app
I have also used a bumper case since the 1st day. I checked my camera lens just now and did not notice any scratches. I think it might be a manufacturing fault.
Not sure my G2 had a ton of scratches too but it never came out in photos... so you should be A-OK... maybe just different glass types.
Note 3 has other quality issues *shakes* lol. S Pen die much? lol.
Meanwhile I realised that the issue with the screen is an actual problem called screen bleeding, related to LCD's back illumination.

I've had mine since 2 days prior to main release (know a guy, mwohaha)
I managed to drop it from my hand, when falling asleep in my chair after working with some stuff for 12h straight - it fell on the floor, and slid a good 20-30 cm across dust, and some "gravel particles" from my shoes - camera facing down. NO scratches.
I'm actually quite impressed

Anyway I removed cover and the screen protector, actually they only covered the beautiful design... Just try a few day without nothing and see if the situation deteriorates.

If I'm not wrong I have 2 years to have free reparations/replacements right? Scratches aren't affecting my photos and are only barely visible with naked eye and only in determinated light conditions. If the problem becomes worse or photos will deteriorate I'll update this thread with my experience with LG's warranty system.
For now this phone rocks.

I've noticed some "light leaks" on the top and the bottom of the screen. It's nothing so disturbing, but it's not acceptable in a high end phone like the G3. :/
Anyone else noticed this? Is more visible when you're seen a darker color on the entire screen.

I've also, but it's very hard to notice and when watching films or playing games is almost invisible.
Anyway guys I've an update for you: I'm not crazy scratches are very visible under direct light and I'll definely contact the seller...
Little update
Sent the phone back to the shop (yes, directly to the seller because it was less than 10 days I have bought it :victory, it should get there on Monday.
Let's see if the screen leaky borders, creacky cover and most important buttery lens are enough for a replacement :fingers-crossed:
I'll update you when the shop will contact me.
Another and last update
The shop received the faulty phone today and replaced with a new one
I should get it tomorrow :victory:

I'm testing it now, they also replaced the wall charger that produced a kind of electric noise (and I forgot to tell them it did...)
Another update after the screen tests.
EDIT:
Anyway, a note: the "old" G3 had a "tight" USB which was a pain to plug... the new one works as it should
the "old" G3 had orrible blacks... the new one has very darker blacks
The screen still have the barely visible blue bar on top (seem to be a G3 feature) and has little brighter bottom borders... so I think it's the LCD itself and not a defect. I tested the screen with a simple app called something like Screen Test and every color is uniform (no illumination problems, darker bars/leaks, nothing.
THIS PHONE DOESN'T HAVE AM/PM BUG!
EDIT2:
LOL, AM/PM bug still present

By any chance can you tell me if you have a model with revised hardware? Because i thought all G3's had a hard to plug in usb (including mine).
About the borders i seem to have them too. I think its normal because i can notice them on all lcd displays like the iphone.
On the lowest screen brigtness, during day light my navigation bar is darker than the black bezel on the phone so i assume that yours is the same correct?
And my charger also starts hissing when charging the phone. Weird thing is it also makes the phone hiss when i have earphones on. I dont know if i should be worried.

Accessed phone infos from dialer and it says rev 1.0 like the "old" one.
Yeah I've set brightness to auto and the navbar is barely visible, not like an amoled but the "old" phone had blueish black which was horrible while watching movies even in a dark room with brightness set to minimum
And the new wall charger has the same problem so I think it's normal and it shouldn't explode
I'm not sure about the headphones+charger issue, sorry.
I can hear interference with earphones but I'm not sure of what you mean...

The blacks are normal to be a little bluish. All lcd are like that and even mine to a small degree.
Thank you for your reply lol. Good luck with your phone buddy
Scratched? How about fully cracked!
First - the phone was not dropped or have any impacts other than what you might get from walking with a phone in your pocket. Other than normal daily use, safe handling and really careful use the phone had nothing happen to it. I cannot pick even a medium bump that happened, but now I have a cracked lens with a hole exposing the camera beneath. LG is warning me that 'mishandling' is not covered ... I certainly did not mishandle the phone in any way.
