I just upgraded from a Lumia 521 to a Lumia 1320 last week. I have a few issues I need help with. I can't run Windows Phone 8.1 DP on my new 1320. Apparently it's something to do with Cricket Wireless. WP 8.1 DP will install, but then it's frequent crash/restart loops. On my Lumia 521, there was a setting to enable pushing store apps/updates from Windows Phone Store in IE 11 on my Windows 8.1 Pro x64 pc to my phone. I can't remember where the setting was in Windows Phone 8.1 for enabling this. Also, on my Lumia 521 in the Lock Screen settings, I could set the time to never, 30 minutes, 15 minutes. 5 minutes, 3 minutes or 1 minute. On my Lumia 1320 the settings are only 1 minute, 3 minutes or 5 minutes. Is there a way to get the old settings for this back ? The 30 minutes or never is useful for updates or backups. The 5 minute crap stinks.
