I cracked my phone doing a dropgap, smacked it with the bars :/ wasn't even big. Had it facing inwards as well.
Now I have my phone in my pocket going spot to spot, so people can text me or call me and i'll feel it, or if i'm waiting for someone to ring me who's coming to ride. But once I'm riding it's gotta be in my bag, can't stand stuff being in my pocket while riding.
