No wonder Nokia changed to a LCD screen on the Lumia 900. Would've been just awefull with a pentile screen in that size with that resolution o.O

I found it interesting you said spots on black background. Because amoled screens pixels arrested suppose to be turned off when displaying black.
Was you phone a first batch to come out? Could it be your panel?

actually, lumia 900 uses amoled. But not the pentile one. The RGB amoled like samsung uses.
Apparently nokia has a deal with samsung as on of their biggest amoled buyers.

Nope it's still AMOLED, it just has a higher sub-pixel density & better sub-pixel arrangement.
Samsung's marketing term for it on it's panels is known as Super AMOLED Plus.
Pixel density being equal, it's only significant practical advantage is reading fine print/text.
It's something that may have been do-able for the N9,* but no, it somehow had to be left out.
Hmmm I wonder why.... :rolleyes:

*It wasn't unprecedented at the time, then again Nokia's never cutting edge w/hw, haven't been for years.

Just took this image: http://flic.kr/p/bCSFLi

Is that what you guys see?
Sir, can those spots and/or lines be seen in a not-so-completely-dark room? The store where I'm getting it doesn't have a dark room, so would putting the phone in a box be enough to see those spots? Thaanks! ;D

i don't think pentile is that bad, I mean, you must do some stressing for you to see it, Well for me, the range i hold the phone when walking and on a day to day basic is fine.


whites, are a problem, But thats what you get when you have new technologies, Like Plasma,

Peoples don't forget try using your Amoled on low brightness, because it has burn-in when you have full brightness and displaying the same thing over and over

Some tips, Avoid using the same time format, every few weeks switch from AM/PM to 24 hrs because the M might burn in. and it will leave marks on your phone screen.

Get a short display timeout- OLEDS break up over time, the brighter the display the faster they bread down.

Avoid Deep blues, Or blues, the blues have the fastest breakdown rate. Greens are better and last the longest.

Try shifting your icons so they don't burn -In and leave marks on your screen.

Something bizarre happened to me just 1 hour ago. I just came back home from my home town using Nokia Drive (aprox 90min) and everything was completely normal. After i parked my car and got the mobile, it shows a green vertical line on the screen. Itīs visible in every app and not in the main menu. Tried to solve it by powering off and on again, restoring...so i assume thatīs a screen problem. Have you had that problem?
I wouldnīt like to send it back to the nokia care point, as it has all my job documents, contacts....
Thx! :)

Back up your data. Move the back up to your computer and ship off to service. (I hope you have your Nokia 1100 ready for temporary use.)

Thank you for great tips!

Do you know what is the origin of black spots on the screen?
