Hangouts audio call not reliable topic

Hey guys! This is my first Android device, coming from the iOS Eco system. I am very happy with my purchase thus far! However, I'm having an unusual problem with the Hangouts audio call feature. I'm running 5.0.1 and the hangouts apps are up to date. During an audio call, I get disconnected with the person I am calling quite often, especially if I lock the screen during a call. But oddly enough it still happens if the device is awake. Is this a known glitch or is it something unique to my device? Any recommendations? I've already tried clearing the cache, but have not tried it again sense. I will also point out that calls are okay when I use the Hangouts app on the iOS devices.

Thanks for any help.

v/r,
KM

How reliable are Nandroid backups? Anyone ever experience bugs after restoring? topic

I was wondering how everyones experience with nandroid backups are and how reliable it is. Do any of you experience any bugs after restoring? Do any of you ever have any problems going back from a touchwiz and CM rom often? (Of course I do a full wipe before restoring) I seen a few users always mention they get bugs after restoring from a backup, I was just wondering if this is just a a few people.

I have 2-3 backups I want to go back and forth from, and there are days believe it or not when I miss touchwiz lol. So going back from touchwiz and cm roms won't give me any sort of bugs or anything? I am just questioning the reliability of nandroid backups
