Hi guys.
I received the u30gt2, great, fast and powerful with the lastest android 4.2.2 from arc tablet (thank you admin :p)
BUT (there is always a but) i noticed (how couldn't i ?) a backlight issue.

Does anyone else have this issue ?
Since i don't want to waste 2 months sending it back to pandawill, do you guys think i can try to fix that myself ?

Thank you for your advice, and i hope i m the only one with this issue.

Despite the backlight issue, i find the screen very fade, colors are not that bright, i was expecting something better on an IPS screen. Also maximum brightness is not that awesome. 
Finally, while 1920 x 1200 is good for reading, it makes black bars appearing on top/bottom of videos, the perfect screen for me would be 1920 x 1080 then.

 

The brightness and contrast on my excite 7.7 (amoled) is much better than on the u30gt2

I had this issue when I upgraded my U30GT2 to Jelly Bean 4.2.2 (which is still a beta)

I lost brightness and contrasts, but not as much as you I guess.

So I reinstalled v4.1 and everything went back to normal.

If I were you I'd flash an older release from the tablet's manufacturer,as this was suggested here. If nothing change, the good thing is that you will still be under warranty. Unless you don't mind paying $80 US dollars (quick ebay search) to buy an LCD screen replacement. In my opinion even this wouldn't be 100% sure that it will get the problem fix, as other hardware and not the screen could be faulty. (bad soldering on wires etc).

Amoled always is higher contrast and colour...like my Samsung Galaxy Note 2...awesome!

Sorry to hear about your tablet screen problems...feel for you...truly...be devastated myself!

Hope all things work out for the better.

 

Cheers.

Definitely a hardware issue...no software is going to fix the LED light not dispersing properly. My guess is that the part that disperses the LED lights is defective or not installed on that side.

As for color issues and brightness compared to IPS...this screen isn't IPS so that's why. It's sort of a hybrid between TFT and IPS that cuts down on the price. Much better than TFT screens but not quite as good as IPS screens.

 

FWIW, my brother just got his in the mail today and there was a small amount of this at one corner but at least it wasn't the entire side (sorry man, that sucks). I think he's OK with it as he doesn't want to deal with shipping it back to geekbuy and deal with being on the move to another place (shipped it to my house, picking it up on the way to his new house ~1000mi away).

 

If I were you, I'd ship it back...see if they will allow you to pay a deposit so that you can hold on to the one you have now and send it back in the same packaging and the new one...basically buy a 2nd one and return the first. I don't think they'd have a problem with this and it'd also allow you to copy over your data easily.
