S8 battery drains very fast after reaching 15% battery level. Within few seconds, battery level falls from 15% to 0%. This is just happening since last month, after July update. Please help.
S8/S8+ does need to have a portrait mode like in One+5 phones. They don't require a dual camera. Just a software update and it's done. Waiting for such a software update. Hope we'll get it soon.
