So my last update was 6th January, nothing else has been released, I'm on BULF and I'm suffering lag and when unlocking the phone the display starts lagging like crazy, I usually switch refresh rates and it fixes it but soon comes back randomly, the recent app menu lags and stutters, the notification shade sometimes stutters too, battery life is not so good, how can Samsung leave us on buggy software for 2 months and not offer a fix? This is bizarre and would please like a Samsung mod to reply and find out what's going on.?
