The closed display halves almost touch, and that can smash debris into the screen.
You know what never had that problem despite years of abuse? My LG V60 Dual Screen.
I still used my V30 as my daily driver until about a month ago. Only switched finally because the software was so out of date and it wasn’t worth rooting it.
Hardware-wise, it was still working no problem. The battery didn’t have the capacity it once did, but would still last a day. Not bad for being over 5 years old.
Dunno if too many people remembered the bootlooping issues of the G4, V10 and Nexus 5X and if that contributed to LG exiting the market.
Oh believe me I remember that V10 bootloop. I liked how lg held out a little longer on removable batteries, and stayed with ir blasters and other niche things when other manufacturers abandoned them. I won’t miss the screen burn in.
