Hey guys,

I have an S4 Active and bought the extra Samsung battery kit. At first it was great, but now I'm finding that whenever I switch to one of the batteries (Battery A), it freezes on the boot. I can start it in safe mode (albeit it runs slowly) but when I try to do it normally it freezes. The other battery (Battery B) boots the phone without issue.

At first I thought it was because I use Action Launcher (no rooting or anything, just downloaded from Google Play), and the first couple of times this happened with Battery A I got it in Safe Mode, uninstalled Action Launcher, then booted it and reinstalled it. But even that doesn't work now.

I don't have the issue at all with Battery B, and it just starts up from power off and on restarts with no hiccups. Any ideas?
