Hi all, i've been recording some rides with mapmyride android application. The device is a Samsung mobile phone namely Galaxy Lite Spica. After i save the ride and check it out on my pc i see my routes are not straight but is a mess. Please see below route i did today. Do you have any experience with this? Any suggestions?

Some people suggest it's due to high solar flames but i don't think so because i have seen so accurate results in other posts. Maybe it's all my crappy mobile phone can do?
