I'm using a eu model and got the mentioned update. The rear (main, not in 48mp mode) is still slow when continuous shooting. Like a 1-3 shots per second. My old Huawei p10 was shooting continuous shots like 6-10 per seconds. I am not sure but Android 9 felt snappier.. when comparing shooting speed.

i agree. even snapping just one photo is slower than android 9, but with 48hd mode on it is normal.
