Seems ok, can use . Regarding the focus, how bad is yours? Mine MY set also, I don't notice anything wrong with it. Most of the time it focus correctly.

To do a basic diagnostic check on your RN4 camera focusing, maybe you can try the scene mode:

Open camera > scene mode > Landscape
                                          > Flower (aka macro)

Landscape mode basically locks down your focusing to infinity, if you cant get clear focused scenery with this option, you might want to try the Flower mode. In this mode, you dont have to touch focus, just point the camera to the object (the effective range i would say is approx 10cm, anything lesser/closer to that might get out of focus)

It is best to test these modes under ideal lighting (especially on Flower mode), with the lack of OIS, the camera AI will bump high ISO to compensate steady shots during low light mode (there is a option to enable "enhance lowlight photos automatically" but i dont find it much useful), which causes more noise to your shot. And steady hands are mostly required even with the high ISO bump.

Just my 2 cents^^

PS: not all RN4 rear camera modules are the same, so the results and performance might slightly differ, most of the ori set now might have the Samsung Sensor, AP sets might have the Sony Sensor. There is no definite answer which sets will guarantees to get Sony sensor. My RN4X Ori MY set was having both Samsung sensor for front and rear...
