The memory used in the HTC 10 is just slower. It would've been great if they used UFS, but I don't think it affects real world usage that much. How often do you have to completely load apps, especially with 4 gb of ram?
GG4 is thinner and more flexible (and more shatter-resistant), GG3 is more scratch-resistant
For the next update we maybe should create two threads, one for news about the official gpe/sense - update, the other for people trying to build it from source?
