Wifey is on an AT&T Lumia 520 (unlocked, but used on Cricket) on latest 8.1.1 Cyan DP after she dropped her iPhone 5c. Pretty sure the phone was on for a couple weeks straight without a reboot, and at some point, no texts were received, and her sent texts were showing as sent. I went to check something in the Settings menu, but it wouldn't load. "Odd", I thought, so of course, I rebooted the phone. Yes, the Settings menu worked again, but all of a sudden, she received a bunch of texts (backdated a couple days), and all of her sent texts from the previous few days finally sent (I personally got two from her, both dated about two days prior, while other people were all "uh, this seems like it was from a few days ago"). I've never had this issue on my AT&T 920 (also latest 8.1.1 Cyan DP on Cricket), but I end up rebooting my phone every other day due to whatever weird battery draining problem the 920 has (reboot always fixes it). Anyone else seen this issue? Do I tell her to just reboot the phone once a week and call it good? She's looking at upgrading from the 520 (understandably) and wants to know if this is a typical issue for Windows Phones, or if it was just a one-time weird thing. Thanks.
