Drop phone - W850. Acting weird.

I drop my phone in the bathroom so hard with a 7 feet fall on a tile floor. I use to have white screen error but somehow it restore it and was back to normal for awhile. When I unlock my phone from sleep, it keeps going into the camera pictures back to back. Scrolling up and down . Anyone know how to fix it? Is it a flash problem or firmware will fix it? Need help.

sounds like a hardwere fault posblie needs a new lcd :(

needs servicing, you can also open it for yourself and putting it altogether in the right place and see whether there is a defect in the sceen top button

I'll do that. Lcd is not crack. It look fine to me.

it doesnt have to be cracked to be broken allso check fexi ribbon for damge
