Keypad light problem

[tuanlinh]

Some time when I close my w580i (slide down), after about 30 second the screen turn off. However, the keypad light still on. And if I don't put any button on the phone, it will be on...forever. If I put anything, the screen will be on, after 30 seconds, both screen light and keypad light turn of.
It's not a big deal but sometime I forget and I burn my battery.

What did you say? Is this flashing my phone?
I haven't done anything with this phone yet. What is the purpose of flashing?

Take it to service center ( warranty ), because I think this is a hardware problem.

Nice day

Try "Master Reset" or SEUS.

So basically I can bring it back to service center and change another phone?

you can bring it to service center if you want.
They will give the temporary phone (loaner).

It depend on problem of your phone.
If your phone is unrepairable, you can get another phone
