Quite a few posts with users using that same device reporting the issue.
We're looking to release an update here soon that should address the problem.
However, in the meantime, are you able to use the phone's stock browser, and go directly to m.fuelly.com? This is the URL to
Fuelly Mobile which that app is just a quick launcher for.
Try to go directly from the browser versus using the app (for now). Let me know if you continue to have trouble.
