Improve sport apps tracking on MTK quad-core

Today I show you how to improve the measurement of sport apps like Endomondo, Runtastic, Runkeeper, Strava, Sports Tracker, etc.

If you practise sports (cycling, running, etc) and you like to track how are you doing, and you would like to improve the tracking (a error on the Mediatek quad-cores in general - like our THL W100 - is making the tracking not so accurate as it should be). Let's improve it with a simple trick, as following:

WARNING - You need your phone rooted.
(If your phone it's not rooted, click here!)

- Install "Root Explorer" app, or other explorer that enters your phone system
- Access "/system/build.prop"
- Edit it, adding this command "dalvik.vm.execution-mode=int:fast"
- Save the file and reboot the phone
- YOU'RE DONE!

Fixing GPS on THL W100 and MTK6589

It's noticed and proved that something is wrong about the GPS on the MTK6589 CPUs in general.
Some ROMs bring the fix for it, but even though if you test your GPS and it gives you a great margin of error (try it on your home! Go outside and test it!), or it takes too long to find a location, you should try this fix.

You'll need to get your phone rooted. (If your phone isn't rooted, follow this tutorial!)
 
- Turn off GPS;
- Download and Install "Root Explorer", "MobileUncle Tools" and "GPS Test" on Google Play Store;
- Open "Root Explorer" and go to the folder "data" or "data/misc";
- Delete file "mtkgps.dat";
- Reboot your phone;
- Get outside!
- Open "MobileUncle Tools";
- Go to "Engineer Mode";
- Go to "Engineer Mode (MTK)";
- Tap "Location", then "Location Based Service";
- Tap "AGPS" and make sure the "AGPS On/Off" is checked;
- Tap "EPO" and make sure the "Enable EPO" is checked;
- Turn on GPS in notification bar;
- Go back and tap "YGPS";
- Wait until get position lock (that will create a new "mtkgps.dat" file);
- Open "GPS Test". Now you should be position lock very quickly.
- You're DONE!

Now you can disable "AGPS" and "EPO" on "MobileUncle Tools", but it's OK if you keep it enabled, it'll lock position quicker.
