Screen is not flat - Galaxy Note II Q&A, Help & Troubleshooting

Hi,
When I had my Note 2 on a table, I happened to glance at it from an angle and could see from a reflection on the screen that the screen wasn't completely flat. The reflection 'bent' as I changed my angle of vision.
I hadn't noticed this before. Has anyone else seen this?

Why post this here?
Questions go in Q&A.

Because I had a question and a search didn't reveal an answer - the normal reason!

coz of speaker grill at the back ...

will need to study physics law and angle of reflection to get an answer to this.

I can think of a couple of reasons...
1. Has your battery gotten swollen or do you use a non-Samsung battery that's slightly thicker?
2. Have you attached a wireless charging pad to the battery or back cover?
This will cause pressure on the screen from behind resulting in a non-flat display.

It is common, that there are variations in glass thickness and they cause image distortion for reflected light. You won't be able to notice it for light coming from the screen.

The earth is not flat

I'm still using the standard battery that came in the box. I am using a wireless charging receiver but there's no evidence of swelling on the receiver or the battery and the back of the phone (under the cover is fine).
I did have a look at a friends HTC One and noticed exactly the same, so I assume it's normal

I'm convinced now it's just normal, I just hadn't seen it before so I got a bit concerned for a minute
Thanks for your explanation.

Try turning off your phone and compare the flatness with and without the battery inserted. Chances are that the charging receiver adds bulk, causing the screen to flex a little.

if you lay the phone on the ground and jump stomp on it really hard, it will become flat.

HTC One X - Tear Down Photos

http://fashion.pconline.com.cn/mobile/1204/2754053.html
Just like the sensation the One X can function seperate from its shell
However these photos also reveal the screen is one part with the metal lining which in tern locks into the polycarbonate
the problems some people are facing is a flex between the screen and the metal frame! glue problem or do we have clips there too?
Also you can see how to replace the battery
Great news that the battery is easily replaceable, hopefully the part is available to the public either first or third-party...

the bad news is the flex, is between the metal and screen, that's certainly a defect
i guess the glue is pooping out due to structural pressure or heat

Your warranty is void anyway, or you wouldn't be changing the battery yourself. ;-)
the more i think about it the more i realize most of the different issues around here are coming of this particular screen defect, where the glass is pulling from the metal frame around, i thought its glue
but i tried my hardest to lock mine back and now its locked into place
so i dont think it glued back, there most be also clips in there for the screen too to clip it with the metal frame
everyone with the flex issue should shut down the phone and try to lock it back
If I put quite a lot of pressure on mine it does stop it from creaking for a short while but it soon comes back.
I've noticed the creaking is worse when the device is cold too. For obvious reasons I guess

That big sheet of copper is for heat spread. Just so you know where all those heat is coming from. Apparently it needs a copper sheet to spread the heat about.
Just saying, for those who dont know yet. My chinese is horrible. That is about the only thing I can roughly understand.

That copper will be transferring heat away from hotter areas, and towards cooler ones. The battery will be one of the hotter areas.
Also, it's likely there for RF shielding to some degree.

This explains why my phone won't charge at the same time as running something processor and graphically intensive.
It says...
"The opposite of taking it apart. As you put the phone back together, push the top area into the calycarbonate casing first then slowly work your way down the sides into the casing. The putback process was similiar to the Sensation, however the One X design may be for making the device more compact and thinner."

Curious thing under the screen.

I noticed something odd while looking for any pre-existing scratches. I'm mostly curious as to what it is. I checked on both my old Nexus 7 (non-2013) and my Galaxy S 3, and it's not present. Any ideas? I'm thinking it's just a sticker, but I could be wrong.

glue might be but I found dust under my screen so returning it.

It's way too perfectly shaped to be glue. It's very precise, so I know it was meant to be there.
Interesting. While I have no clue what it is I want to confirm that I see it too. Using a very very crappy ultraviolet light I ran it across the screen. Same dimensions and shape (I can see what you mean by perfect, corners are round).
Hmm...

Xperia z compact left side slightly misaligned?

Hi, I just got the phone yesterday and right away I noticed that the left side of the aluminum framing is a little off?
It's hard to notice but if everybody can please take a moment and look at the left side, where the magnetic charging port, does that section tend to extrude a little more than the rest of the frame? Compare that part to the port flaps on top from an angle and you should see that the charging port section is extruding a little more ?
Thanks for your time and replies.
Sent from my iPhone using Tapatalk
hmm, 50 views and nobody replied, does that mean nobody is having the same problem? just a defective unit ?
There is in other z1c devices too. Not all. Don't worry, I don't think it is a defect. Everything works as it should including magnetic charger and water resistance!
So in some devices, they aluminum frames are perfectly aligned while others are not and it's not considered a defect? I don't quite follow the logic here. Anybody else has a slight misalignment? It's not major but on an angle you can tell that the Magnetic charging port is slightly different compared to the flaps on top.

Have I offended you in anyway? In my post, I wasn't refering to your logic that I didn't follow, I'm referring to Sony. If there are obvious units out there with perfect alignment and some that aren't perfect, Sony should refer to those as defective units and issue a recall to fix it, no? It's a premium device after all. Didnt mean to offend you if i did, I'm sorry.

I don't have the phone with me at work today, but those of you who have the phone with you, maybe you can pick it up and view it a little. The frame where the magnetic charging port sits, seems to protrude a little more than the frame near the flap areas.

If I stare at mine hard enough, I think I can see the part around the charger protruding slightly more than above and below it. But the difference is very small and not noticeable unless you're looking for it.

Look at angle from slightly bottom up, it's very minimum but once you find it, you can tell that the flap areas are more indented than the magnetic charging ports. I saw it last night once I got the phone. Try to turn the phone a little while you're looking at it, if the phone is sitting down on the table its very hard to tell. You have to be holding it and looking at the frame while moving the phone around. I just need to make sure that it'ts not a defective unit and that's how these phones were made. If not I'll return the phone for a replacement. All else with the phone is fine though. I'll also stop by a local store later to check out the z1 and z1s to see if they have the same problem.

okay here are the updated photos that i took. notice that on the left side, its not completely straight because of the extra protruding from the magnetic charger port.
I was kidding earlier with the OCD .
To be honest, I do not see anything wrong in the pictures. Maybe I really can not see it. You need to get right the reflections in order to evidentiate such think in a photo.
Bottom line: if YOU do not like it, go ahead and exchange it or return it. Anyway, the small, fine details, that you are looking after, will not be at the level of an iPhone. That's a fact.

I don't see anything either in those photos.
To be sure that you're not just seeing an optical illusion from the reflections of the changing surface along that edge, why not just take a ruler to it and measure? Or place on a piece of paper and trace an outline? Does it wobble if you rest it on that edge?
You'll never be certain if you just rely on your eyes.
This is mine.

The way you've applied your screen protector would be more annoying. Lay the left side on a flat surface and that will highlight it more, but to me it looks like the protective plastic is giving the illusion that it is.

Display loose

Hi guys
Can you check curved edges part of display near top and bottom portion to see when pressed with little pressure whether screen goes down ? Especially near front facing camera .
Thank You
Checked near the front camera area and yes ,the screen goes down a little upon pressing in the edges with little pressure.

I agree, it's not a major issue, I was thinking to take of the screen completley and reglue it using some duble sided tape... But there is a risk of breaking the screen in the proces... It's not worth it
What about putting duck tape across top and bottom of the screen? Don't forget to make holes for loudspeaker, front camera and proximity sensor. And for microphone and fingerprint at bottom
So, you're all saying that tbe whole screen is moving a bit in the case? Check teardown and you'll see that is actually glued. Not my favorite solution but I suppose is cost effective.

Bought a screen off eBay, yes you need to heat up the glue underneath the screen with a heat gun.
Got the new screen in after I had to remove all the small piece of glass that was still glued but it's not an easy repair and I still have screen issues I assume the screen isn't the same quality as the original one which comes with a silver backing plate.
In bright sunlight my screen turns blue
The battery maybe will never die, because a bigger LiPo much longer live as a small one and we just load again all 2 or 3 days. So that's ok that's build in. Maybe the screen is much earlier broken. Hope it doesn't broke
My battery has 3600mAh(3597)

If you observe carefully just above volume up button screen is not even inside the aluminum frame there is slight gap. And if you apply little pressure screen goes down. Is this normal ?

Hi, please see the picture and tell me if it's happened to you, the back glass not fitting correctly after only 3 months of normal use, no drop, and what do you suggest a solution? thank you.
I was just noticing this on mine a few days ago. But I cant remember if it was always this way. I noticed it after my phone got super hot from charging, at 1st I though it was the battery swelling. Device cares app says my battery is healthy. So idk but the seams seem to be consistent all around just wider than I thought they were.

Probably an adhesive failure/improper assembly. May or may not effect it's water/dust resistance.
Needs to be disassembled to be examined/ repaired.
Extreme heat weakens the adhesive bond of the strips used to secure the back panel. It's possible that careful heating and then pressing down could reseat it, but given the cost of the phone probably best to leave it to an experienced tech. Also the adhesive surface may have by now become contaminated with dust making simple attachment impossible without replacing the strip.
