Managed to get Windows 10 installed after updating to 8.1 update 2. The new default camera app is messed up. It shows several small windows of the same object (like a series of frames of the same photo) I am aiming at instead of one large rectangle. They are located on one side of the lcd with an overlay of setting choices. Not useable to frame a photo. Switching to the old camera app works but really want to try out the new Windows camera app. phone is a 925.
