Hi,

I notice that when I touch the screen I see strange colors- like rainbow bubbles under the screen.
Is it normal or not? if you touch your screen, do you also see like rainbow distortions on it - like oil spots? (newton rings)
Do you suggest me to ignore it or take it to LG and ask them to replace/fix it?(my phone is 7 months old)

that is a normal thing, but you shouldn't be pressing like that the screen :/
it's Liquid Cristal Display = LCD so it is normal to see those colors when screen is pressed, but stop pushing it XD you can damage the screen

Lol, thanks for the information, I thought this way but wasn't sure.

but what if I also see those strange colors even when I press not very strong on the screen but normal+ ? Should I take my phone to repair? (it's free for me, lol:cool:)

I think so, it might be a defective LCD, and if its free you should do it... I mean it's somehow normal [because of the liquid cristal] but if that happens whit normal pressure then is not that normal... :p

Maybe the gorilla glass (the one you touch, not the LCD) is softer/looser than normal and not rigid enough... I noticed a softer/thinner Gorilla Glass on the Black than other devices.. Quite annoying sometimes, it makes the device feel fragile or cheap XD

Did someone also notice that when applying little pressure to the screen, like an oil spot appears and in some spots the screen feels flexible when touching it a bit stronger?
It looks like this: (It happens only when I touch the screen a bit stronger than normal)

Mm it does happen but not that large and when it happens it gets back to normal quite instantly.. Could be a counterfeit OB lol... I always knew that the Gorilla Glass was not normal on OBs.. you should go to an LG service or somwthing like this to get it checked.. It shouldn't be like that, at least wheb applying a small pressure

Ok, thanks for replying, now I know that my OB is not the only one with this defect.
I already sent my OB to repair when it had other problems in the screen and they didn't replace it with a new OB:mad:
now I'm going to send it again to my Cell provider and I'll ask them to replace my defective OB under LG's manufacturer Warranty.
Any ideas how to convince them to replace my defective OB with a new one and not only replace the digitizer or lcd screen?

Hi,
I found the specific name of this phenomenon: newton rings
there are many threads in XDA about this phenomenon but no one about OB.
It appears only when I touch the screen, (maybe it's because I always keep my phone in the pocket.)
It looks like that:

Is my LG Optimus Black defective or it's normal?

Honestly I don't know... I never had to replace my phone by a new one...

Sorry my computer is very laggy

It's important to me to know if my device is defective or is it a normal phenomenon with OB?

This is only what I think, but to be honest I feel that's not normal, I mean even if I press really hard my phone's screen it doesn't look like that not even close to that, I think you should send it to techs
