Zuk Z2 Pro is a pretty good option, but not sure if could be found in local or not, 6gb ram 128gb rom, 13mp samsung iso cell with ois, 5.2 inch super amoled, sd820

The standard Z2 is considered the best budget performance phone available for now, just that from what I heard those sold in local are with custom rom which cant be upgrade using fota (correct me if I wrong). For those which could afford more Z2 pro is quite a good option as 6gb & 128gb version could be found at 1999 rmb.

I guess they are using the z2 plus rom now for the z2, does it have google launcher as default launcher? 5 inch screen with 3500mAh battery should be pretty sufficient overall.
