My device Lumia Dual 540 had an update about a year ago where Camera and Flashlight stopped working and I fed up trying to fix it :)
About 2 weeks ago there was a night update and suddenly, I found Camera and Flashlight working again. :O)
Yesterday, or say today early morning, there was an update (I said to myself, wow, phone is getting better and better and they are fixing things), after the that update, I wanted to check Flashlight, just in case, I found Windows crashed and restarted automatically, I found no Desktop at all only the menu is shown and this menu is missing lots of applications, moreover Camera and Light are not working anymore. Do Microsoft guys make releases without testing?
How to rollback my Windows Phone 10 to the previous release?
