engineering mode

Is there a way to select all LTE band in BAND MODE? because of weak signal

@babyioling You can try (on your own) by Mobile Uncle Tools or MTK Engineering Mode (search on Google Play), or also by ‘dialing’ the secret code to open MTK eng mode * # * # 3646633 # * # *.
There is a GUI to change many low-level mobile and WiFi settings, but don’t know would it work or brick the phone ;-(.
Particularly, you cant enable 3G/4G bands that are not supported (by modem, in hardware)

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
