So I have an Lg optimus f6, I've had it for a while now (since around last christmas) and it's been through some drops, but I have a protective case and a screen protector on it, then out of the blue it started acting up, now whenever I press the side button to lock my home screen it pops up the menu with the shut off and reset, the power off, and the airplane mode options. Then when I try to get out of the menu by pushing the home button it automatically selects the power off and reset option and shuts off, I've tried taking out the battery and blowing on the battery compartment but the only solution I've found so far is turning the backlight timer off completely which makes sure it never locks but also wastes my battery, does anyone know how to fix this? Should I replace my phone? This is really frustrating so I could really use the help, thanks! ^^
