There were other things. Their g7's often had hotspots on the bottom of the screen. Many phones would have their charging ports die. Many of their more creative phones were also either budget, underpowered, or under engineered.

I am writing this reply from a v60 and I dont see any reasonable replacements other than mild side-grades. But boy oh boy do they have issues. Moreover, if you can even convince them that they should fix your phone, they only offer the repair it which takes times, never a replacement/refurb.
