When Marshmallow came out for the S5 I upgraded. When I did every time I restarted my phone things like permissions for apps in the accessibility settings and apps I've set as defaults in the settings would be forgotten. A few days ago I did a factory reset on the phone and upgraded to Marshmallow again and the problem still persists. I think that rules out a particular app doing this. Has anyone else had this issue? Is there a fix?
