Launch the app, go to “Engineer Mode “, then “Engineer Mode (MTK)”, horizontally scroll to Location, and tap Location Based Service.Install Mobileuncle MTK Tools from the Google Play Store.I followed the instructions, and amazingly Nike+ Running can now find my position with GPS within 5 to 10 seconds. So I tried to find a solution, and Google pointed me to an article on Gizchina explaining how to fix poor GPS in Mediatek phones. When I wanted to start running, the app complained about weak GPS signal, and tried to lock GPS for about 10 minutes, until I decided to give up. I’ve also tried Nike+ Running, an application that keeps track of your running sessions with GPS, gives you some audio feedback as you run (distance, time and speed), and compares your performance to the average, and your social network friends. In Google Maps, I could get a somewhat accurate position thanks to mobile network location, but it was clear it could not lock GPS. I’ve enabled access to my location, GPS, and Google’s location service using Wi-Fi and mobile network. I’ve recently purchased ThL W200, an Android 4.2 smartphone powered by Mediatek MT6589T quad core processor, and I’m trying to test a few things including GPS.
