When I boot up my moto g3 the first logo that appears is a upside down Motorola sign with two dots for eyes in between the arches ... This isn't a joke .is this normal my phone isn't rooted or anything
I am 100& sure I just factory reset it the other day but the weird thing is I went to sleep last night with my phone on and this morning it was off and had that symbol when I turned it on
If I was you I will check Motorola's website to see if you can download the factory firmware for your phone and install it. I am pretty sure Motorola have software tools that can do this and of course you need a PC.
This started to happen with my Moto G3 a month ago and it is also heating and consuming battery very fast after that. May be a virus I'm afraid. But I can't imagine how it was infected. I'm very careful with apps. Never install apps that don't belong to the play store. But plugged it to my colleague notebook a few times to test an app we were developing.
