Rainbow Effect on Screen

After being in my pocket for some time, there is a rainbow effect on the screen. I can change the location of this effect if I push elsewhere on the screen; however, it seems to concentrate itself right in the center. It has no ill-effect on the touch screen but it is visible under certain angles when the screen is on. I am using the screen protector that came with it. After some time being out of my pocket it dissipates and looks normal.
Anyone else experience anything like this?

Yeah, I have.. I haven't noticed it's touch sensitive, but I've seen the problem while rebooting and also randomly while using the phone.. And it seems like for me the screen gets progressively worse and starts losing all contrast and fades to white. A reboot always fixes it.
My guess is something in the video drivers flips out. But the first time I saw it I thought I had a hardware problem because I found it that way in the morning out of the blue, but I guess it had started doing it 'itself' overnight or something.

I dont think it has anything to do with the screen itself. But the digitizer and the multiple layers on top of the screen that the digitizer is composed of.
Newton's rings isn't it?

Yes that is exactly it - the diffraction of light between 2 surfaces, is it normal; however?
Thanks!

Nooo, then maybe what I'm talking about is different. I'm talking crazy screen, weird 'rippling' going on, screen slowly turns more and more white. I know what newtons rings are.. It's sorta visible in sunlight.
So perhaps I'm describing a different issue. Mine is definitely something with the phone, not the layers.

G1 Notification LED

I recently gave my phone to someone to replace the digitizer as there was a crack. Now the LED is stuck on the blue light. Whenever I turn on the phone it remains there. Is this a problem with the LCD screen or is it a problem with my firmware is what the person told me was the problem?

It's not the firmware. something went wrong while replacing that digitizer. Firmware shouldn't be getting any problems from a replaced part that doesn't concern memory
Also, it's probably a problem with the trackball, holding the trackball while booting makes the led turn blue

I heard that when that happens the phone does not turn on at all, but is working fine.

If your screen doesn't turn on or you think it doesn't charge, look here

I just received my nexus and I thought the battery was dead cause it showed the battery icon briefly. I left it charging for an hour and nothing. I tried the flashlight trick on the screen and I could see the welcome screen. I disable the automatic dimming feature and now my screen turns on. It must be a software issue on the sensor. I don't know yet.
So you shine a flashlight at the ambient light sensor and it turns the screen back up? Like the sensitivity of the sensor is too low? I'll have to make a mental note of this for when mine finally comes in.
Yes if you can't see the screen. If it still doesn't work, shine the light on the screen and you should be able to see the welcome screen. I don't know if you ever had your laptop LCD inverter burn out?
Thanks for this post. I had the exact same problem. I struggled to get up and running, but figure it out with the help of my GNex.

Thanks for the info.
I had this problem and I'm getting mine replaced. This is almost certainly not a software issue, else everybody would be having it (and if it were a misconfiguration, it would go away with a flash of the factory rom).

Do a search for light sensor, and you'll find other people with this problem.

True, I can't even see youtube in landscape mode cause the screen will shutoff. I have to have it in portrait mode.
Sounds more like a hardware problem. A light should DIM the screen, not brighten it. The sensor is reversed.

So when you walk outside to the bright sun, you would want your tablet's brightness to be at the lowest setting? I doubt it

[Q] display hypersensitive

Hi!
My phone got a broken screen, but I got a replacement device from the insurance.
Trouble is, after a while with screen on the screen seems to become hypersensitive - it's nearly impossible to enter text through the display keyboard or just to zoom and move a webpage
After switching the screen off and back on again immediately it's OK again for a while.
Anyone else seeing this behaviour? I reckon it's a hardware problem, but maybe someone has a different explanation for this problem?
Do you have any Screen Protectors? Just the Original ASF?
I didn't change anything with the phone except for the ROM (can't stand stock ), so it's still the original one.
What does ASF mean?

You should have the Anti-Shutter Film on your screen with the Sony Logo, many reported sensitivity problem after remove it. If you have ASF sometime apply another Anti-Glare Screen Protector on it can help (like in my case) with the touch screen.

[Q] Screen won't switch on and neither will the charging led

Hi guys,
My mobile phone seems to have a not working screen. The weird thing is that the backlights work and I can connect via adb, but the screen and the charging led will not.
Do you think it could be because of a faulty or not connected wire? I want to make sure that changing the screen would solve the problem before buying one.
Thanks!
Update: I just noticed that the screen is on but extremely dim. It´s not possible to see anything at all.
Could be LED backlight
Does moto logo show, when rebooting?

Yes, the mobile works normally. It's just that the charging led (the one on top of the screen) won't work and the screen is extremely dark. It's almost impossible to see anything unless you are in a room with just a little light.
The brightness is set to 100%. It's probable a faulty screen or a loose connection but I would like to find a way to know if that's the case

That was not what I was asking, is the moto logo as bright as it should be when rebooting?

ah sorry. I see what you mean. No, the screen is always so dim that it's really hard to know if the mobile is rebooting.

so it's not a screen setting or bad app, and not likely a software issue.
It could be a bad screen LCD connection, but guessing the LCD screen needs to be replaced.
can buy a new LCD for about $30 on ebay, but maybe more trouble that it's worth
Motorola Droid 4 Screen Take Apart Repair Guide
could have someone else fix it
http://www.repairsuniverse.com/repair-service.html
or it's time for a new phone
I will try to fix it myself. The price of getting a new one will be similar to the price of sending it to repair so that would make no sense.
Thank you very much, sd_shadow
