F1519625749128, Aug 10, 2018 : As from OPEN BETA13 update there's a lot of bugs that need to be addressed and solved. First it's a camera when ever I open camera it shut down automatically saying "Unknown error". To clear this is even tried clearing up the cache using advance reboot option even though there is no changes happened. And coming to messaging it has drastically become slow and often crashes while texting. These two issues are major enough for One plus users and I hopethis will be sort out and fixed in next update. And I am personally wishing for a stable version update rather than a open beta update.
