On your phone, goto Settings app ➡ Privacy ➡ Analytics ➡ Analytics Data ➡ scroll down a bit and you should see a couple types of files (sorted by name)
"Fence-hang-KeepSafe ..." with a date as well (these are deadlocks/hangs)
"KeepSafe ..." files with a date next to them (these are crashes)
Once you tap on one of those, there is a share button at the top right (see screenshot) where you can email them to us or share them back to your computer and share them with us that way
