[Xiaomi Redmi Note 5 Pro ROMs, Kernels, Recoveries,] barul42:
Some issues I've run into w/ 20200403 and 20200406 (not sure about the previous build, I've just noticed it w/ these two), in the settings the back camera is set to record 4K while it's not supported. Trying to do so will result in an error saying the app can't connect to the camera, or this in logcat :

And also while using Slide to browse reddit, if I try to open an image with the internal viewer, the app becomes unresponsive and needs to be killed. It worked fine with 20200305 build, but I have nothing in the logs to get infos from.
