laisimo l1

I just got my Laisimo L1 and have been reading about the numerous people having their mod go full brick after update, so skipping that for now. My question is about the voltage output meter that shows on bottom right of screen. Does anyone know why it just stays at 0.00v no matter what I...

Just a quick look at the Laisimo L1. Enjoying it so far, the battery life is surprisingly good even with the 2.4 inch color screen.
