If you're having GPS problems I feel bad for you son, I got 99 problems but my GPS ain't one! *thanks to this handy guide
It seems that GPS in the latest quad core MediaTek devices is notoriously poor. I've certainly seen it in my own experience - it was flaky on the iOcean X7 I had and the Sege XYZ-X1 I still have has awful GPS. Or rather, HAD awful GPS, until I happened upon this post on GizChina.
Entitled 'How to fix poor GPS on MediaTek phones', it shows you how to give your MTK phone's GPS a new lease of life in a few simple steps.
Head on over to GizChina for the full details, but let us know how you get on and if it made GPS vastly better on your device as it did for me.
