I've just noticed an issue with the camera zoom on my S21 Ultra since updating to One UI. The camera performs fine when using 0.6x, 1x, 3x and up to 9.9x. Once it hits 10x zoom (and anything above), the camera display shakes to the extent you can barely see the image, this happens for a video also (this is with phone on a non-moving surface to eliminate my movement). I've read of similar posts where it was suggested the image stabilisation was causing the problem but not found a solution. As this previously worked fine before the software update I'm sure it has to be linked, and not just hardware.
I've made sure all software is up to date, performed a soft rest, tried in safe mode, deleted camera cache + data and manually trying to fix the focus but all made no difference.
Does anyone have any suggestions? I'm placing my hopes on the next software update resolving the issue, as a last resort going via warranty but want to avoid that with the disruption of sending the phone away.
Thanks
