Hello everyone, i own motorola motoluxe, it has been a pretty good phone so far. The only problem was 2gb memory card that eventually want enough. Today i got a new sd card(kINGSTON 16gb SDC4 card). I tries to install a few apps thinking that i will never run out of memory again. But unfortunately all the apps i download show me 1 of the 2 error messages: The file was not signed correctly or The application crashes. I restarted the phone a dozen times, but its the same. I put back the old sd card which is sandisk 2gb. Thats works like a charm... Has anyone had a similar problem? Do you think my problem will be solved if i get another brand like sandisk?
