Hey guys, my q10 I bought used came with 10.3 installed, and it looks nice, but it's really buggy, so I think I'd like to downgrade. my issues are that it is only showing 1gb of ram in the device manager, which is usually sitting around 870 mb's used, and the phone is not very fast. The other issue is that the camera was working, and then suddenly stopped, giving me the message "the camera could not be started" Any help would be appreciated, thanks!
