OP = original post or original poster, depending on context.
Do everyone a favor and list what you've already tried when you ask your question. We don't know if you are knowledgeable enough to try or if you even know what a hard reset is. You state a problem and ask if anyone has ideas. Well, yeah, let's start with the basics, unless you've already done that. Like I say, save everybody's time and list what you've already done and any relevant info about changes right before the problem occurred.
At this point, if I were you and weather bug says there should be no conflict with your model or OS version, I'd backup the device first and then do a security wipe, choosing to delete third-party apps. Then install weather bug and see what happens. If it works, then do a restore from your backup and add your third-party apps one at a time, testing weather bug at each step.
That's me. See what others say.
