In my rooted Morotola Razr D3 (XT920) firmware 2_32D_2009 (Brasil) it´s not possible to enter MTK Engineering mode (Mobileuncle MTK Tools in play store), even it is a MediaTek MT6577 based phone. When I touch this option, the screen blinks and nothing happens.

What I did in my case, was change this two files below (root needed, folder /system/etc – you can use root explorer/built in text editor to change this config files)

file “conf.gps” , delete everything and put this:

NTP_SERVER=0.south-america.pool.ntp.org
NTP_SERVER=1.south-america.pool.ntp.org
NTP_SERVER=2.south-america.pool.ntp.org
NTP_SERVER=3.south-america.pool.ntp.org
NTP_SERVER=0.br.pool.ntp.org
NTP_SERVER=1.br.pool.ntp.org
NTP_SERVER=2.br.pool.ntp.org
NTP_SERVER=3.br.pool.ntp.org
XTRA_SERVER_1=AQUIxtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=AQUIxtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=AQUIxtra3.gpsonextra.net/xtra.bin
SUPL_HOST=supl.google.com
SUPL_PORT=7276
SUPL_TLS_HOST=lbs.geo.t-mobile.com
SUPL_TLS_CERT=/etc/SuplRootCert
INTERMEDIATE_POS=1
ACCURACY_THRES=2500
DEFAULT_AGPS_ENABLE=TRUE
DEFAULT_USER_PLANE=FALSE

Change where its says AQUI for h t t t p : / / (all together)
You can change the NTP servers to your country settings (go to pool.ntp.org and find it.

file “epo_conf.xml” – at the end of file, change to “yes”:
–>
epo_enable=”yes”
auto_enable=”yes”
update_period=”4320″
/>

Make sure the permissions for the two files (gps.conf and epo_conf.xml) is RW-R–R–, if it is not, change it.

Go to play store and install app “GPS Status & Toolbox”, test the GPS outdoors. I hope it works to you, in my Razr D3, now, it takes less than 60 seconds to synchronize to satellites, before, could take more than 10 minutes.

Forgot to say, after edit the files, reboot the phone.

Hi.

I’m considering getting a cheap Chinesse phone but the GPS problem keeps me from buying it.
What cheap brand doesn’t suffer the problem (Meizu, Jiayu, THL, UMI, Zopo, Inew, Huawei…).

I don’t mind if there is just a “software” option but I don’t want to buy a mobile with a bad GPS chipset or even without antenna.

Regards.

I have Jiayu G2 and it gets a fix in 2-3 minutes without any special software or setting. My Samsung Galaxy Tab 2 gets much faster fix. I think all MTK chipset phones have slow fix problem. Some of them even does not get a fix for long time.

Hi man,
And do you know if the brand ZTE also uses mediatek and have the same problem?
For example the model ZTE Z5s.
In some places the specs say it can also use Glonass, in other it say not.
Anyway this brand is much more expensive.

What I don’t like is that it seems you can’t replace the battery and it’s only 2000mAh. I don’t know if it could be possible to replace it even if it’s not supposed to.

regards
