My solution is simple. First, being of generation not feeling the need to fidget with a phone all the time and finding anything less than a full size keyboard awkward, I very infrequently text on send anything on my phone. Second is the fact I do not store any nude or sexual pictures or videos on my phone. I've lost phones in the past and are too worried about it either happening again or having a friend or family member borrow or use it to keep anything incriminating on it.
