Still experiencing a lot of bugs with my iPhone 5.
Apps crashing.
Text tone randomly gets quiet. Only fixed with a reboot.
Data randomly chugs. Usually fixed with a reboot.
Sometimes they phone gets so whacked it literally reboots itself. I'll be doing something on the phone, and suddenly the phone reboots.
Certain built in apps, like the App Store will just stop working. Randomly they'll start working again later.
I've already done a full restore from iTunes and the problems continue.
Before anyone goes and tells me to exchange it, it's hard to believe these are hardware related, when they show all the signs if being software related.
I'm 90% sure this is a hardware problem. My last phone (even though it wasn't an iphone) behaved the same way because of hardware problems. Random reboots, apps crashing etc. Exchange it as soon as possible.
My iphone has been completely free of problems.
