[QUOTE=tssphysicsboi;42339864In terms of wifi, it's still pretty slow unless really close to be router.

I noticed the problem too, maybe it is because there is no nvs_map.bin file in the /system/etc/wifi/
There should be written calibration of the wi-fi as well as MAC address.
Does anyone have this file on the phone somewhere. The phone should be rooted, so you can be able to search whole memory.
Because I'm new user I can't post outside link but you can search Google "NVS_Map Creation *AKA How I fixed my wifi/MAC issues"
Does anyone noticed that Wi-Fi MAC address is changed every time you switch on/off wi-fi?
For rooting the phone you can search YouTube "STAR X920 ONE CLICK ROOT OR ANY MTK6589 DEVICE!"
It is very easy.
