There is one common major problem with Mediatek powered Chinese phones
and that is their GPS function. The main cause of the problem is the
budget GPS chip as well as the lack of proper routing and implementation
of antennas within the phone to facilitate a better signal and fix.
Therefore, there are two solutions to go about improving the poor GPS
performance. One would be a hardware fix whereby the phone will have to
be disassembled to install an extended antenna. The other, which is what
this article is going to cover, is a software fix where a few different
phone functionalities will have to be activated to improve the GPS
performance.
1. Delete a file which mtkgps.dat (/data/misc)
2. Reboot
3.
Go out into the open field
4. Enabled in the positioning GPS, EPO, A-GPS
(you can download the new files EPO)
5. We go to the engineering menu *
# * # 3646633 # * # *, select YGPS, bookmark Sattelites - and expect to
be fixed in a few seconds, you can wait a little longer, until I was
driving to work about 10 minutes looking at the green points
6. Exit the
menu and engineering YGPS All. GPS should start normally. Previously,
after a simple initialization through YGPS (without removing mtkgps.dat)
first, too, everything worked (and not because the Wait), and in the
evening - not at all. Now always works the same way.
If typed positive
statistics for this procedure - consider GPS "repaired"
