The LG Optimus L90 is a smart phone from the third generation of the "Optimus L" series of phones manufactured by LG Electronics.

Why is my phone not allowing me to do anything?

For some reason, my phone started acting up. It factory reset itself, and I can no longer do much. The back screen won’t change, and no matter what I do I can’t get a lock screen to actually turn on. Along with that, there’s no longer a bar across the top of the screen, meaning I don’t have access of seeing anything. I can’t access any previously opened apps either.

You have to hard reset the phone,This actually happen some application causes crash the system.So if factory reset is not working at all you have to firmware upgrade.
