I just got my new iphone 5s last week. Sometimes it crash. Even appstore, music and voicememo crash. But it does not happen frequently. Then there are about two times the phone freeze for a moment while I was browsing through my photo and when I was downloading app. Here is my diagnostic and usage screenshot. I have restored my phone to factory setting yesterday but the same problem still persist. So is my problem serious or is it normal? Since the apple store is quite far from my house, I just hope the problem is worth to go for.
