NEGATIVE POINTS
After a month the battery dropped me. The phone has put over 10 hours to load !!! Amazon has changed me the phone without problems. The new works for the moment.
The GPS wasnt terrible amazon before changes me the phone. He could not determine a position on the accuracy of 500m, really top !!! since the replacement by Amazon GPS running much better!
In summary: very good value for money, but it is not about to fall well !!!
Special mention for the Amazon service!
