Hi, zegenie!

Which Firefox OS version and device are you using?

Hi, sorry for the missing details.

I'm using the foxfood build for xperia z3. It's the release posted here: http://fxpblog.co/firefox/nightly/

All images flashed to the device were contained inside that archive.

This seems like a hardware incompatibility issue.

I've tried contact them by Twitter, trying to know if this bug was faced by more users, so we will eliminate possibilities.

I will continue on this as soon as they respond to me. If you can, please try asking them the same.
