How to Fix poor GPS on MTK phones

 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"
