Flashing "LG life's good" screen

[ann9700]

Need help for my LG G3. It is looping or continually flashing the lifes good screen but won't power up. I already took the battery and Sim, sd cards out. This did not help

How long have you had this phone? Have you noticed anything strange or off about your battery life/performance?

I have heard that the G4 does have certain models /serial numbers that will do the looping; but I have not heard of the problem being present (or not as prevalent) for the G3.

Have you tried reaching out to LG/your specific carrier? They seem to have good warranty - if it's something like your battery/a similar defect, it should be covered.
