I have also installed to a Lumia 535. Again, very smooth when it's working.
The 12 erroring stuck apps are now down to one, Rate My Device.
However, it hangs, becomes totally unresponsive to touch, several times a day, meaning a soft reset is needed. If it hangs in an app on the SD card, the card reports as corrupted on restart. Never had this on earlier builds.
The Automatic brightness is erratic, it will leap from a suitable brightness to eye searing, and then you manually change it to low, a few munites later it will leap back to what low is supposed to be!
Also, if you move an app using Storage, it loses its icon. If you move it back, the icon reappears (!) This one has been reported on Feedback, please upvote.
I really cannot believe this is a later build than the 950 is shipping with. We are all on a beta test programme that we chose to be in, this stuff comes with the territory. But shipping a device to potentially new customers with what is beta software is not acceptable.
