I don't know what you mean by bounce. But I have a a problem with my LEDs. The keyboard goes on and of every 5 seconds.
rebooting did not solve the problem! This problem only apears on the lowest LED light settings, I figured out.
Anyone with keyboard backlight problems?
I have to correct me: Unfortunately, the problem appears on any LED level. Backlight still goes on and of every 5-7 seconds.
I tried to solve it with CosmoCtl (rooted device) but no chance.
I will check if the unrooted Android also have this issue.
