Should i take a backup.
May be you are right.
My friend got the same update of 38mb
Update for Oneplus 3/3T Coming Soon
same here, but no solution from oneplus.
I thing you haven't read it properly otherwise you would have understood the problem.
When will OnePlus fix the Oreo bugs from Oneplus 3t, Phone Heating Issue , Battery Drain Issue, Phone freeze Issue, Wifi Issue and many more issues.
