Hi I'm new in this forum, and android, and looking for some help
some weeks ago I received a chinese android phone dual sim
BML GT-6802
android 4.1.2 (I doubt this, in somewhere I found the phone identify itself as android gingerbread....)
CPU 400 MHz~1GHz
RAM 216.5 MB
rooted using zhuodashi

the problem is wifi range is only 1 meter an bluetooth 1 cm
I looked for update with no luck
I called the seller
I tried iwconfig,hcitool with no luck (maybe I didn't have some command, or I wrote something wrong)
I tried the antenna fix of here forum . xda-developers . com / showthread.php ? t=1688538 (only stick the cable because I don't want take the risk if is not the real failure)

I think the phone has some instruction limiting the TX (or maybe the wifi/bluetooth module (HW) is defective)
some ideas?

have a nice day
