Okay so this question seems to have already been answered. However, I have been through all of those threads and I've tried everything. So my stock messaging app on my one plus 2 started crashing a few days ago. I cleared cache and data which didn't change a thing, I then downloaded a third party messenger app (textra) which, when set as my default messaging app kept crashing too. I then tried making Facebook messenger my SMS app but it started crashing, and now when I receive Facebook messages it crashes too. I then tried fastbooting it which did absolutely nothing. I'm a little at loss of what to do.. Thank you for your help.
