Dear users of the Microsoft Lumia 535 DS, tell me the phone has been updated to 10 now there is a problem with updating the software, for example, Word starts updating and at 5-10 percent it is cut down with all the software, and can only work with the latest versions. I already regret that they put 10-ku, can someone tell me how to put back 8.1. T. this son has nothing important there, you can reset everything. ATP in advance.
