Hi. I just purchased an Xperia Ray, but over the past few days I'm having problems downloading/updating applications from the Android Market. When I try to download/update, I often get a prompt "Unable to download application due to an error. 500". It took me multiple tries over a few days before I could actually update my Gmail, Google maps, download Skype and so on... I've done what other threads have suggested, such as clearing of cache/data from market and the download manager, but they don't always work. Is there any way to ensure every download is a successful one? Also, I read that the battery will adjust itself? That sounds pretty cool. I never really thought that was possible. Over the past few days I've been experiencing bad battery performance. If I set applications to refresh often, (like, maybe Facebook refreshes every 30 mins) will it severely drain the battery? Thanks in advance for the help.
