The problem is with your home screen. A soft or hard reset will not solve the problem. Modifying the stock android app will not help either. Your apps are not causing the problem. There is nothing wrong with facebook app or any other app. Yes there is a glitch...a minor glitch that is causing this pop up to appear "android stock rom has stopped working". I've been at this for 6 months trying to solve this problem. I've done so much research and have found that a lot of people are having this issue. Whatever you do don't throw away your phone. There was an update that was issued in June of 2017. It did affect some phones but not all.
First of all the issue is with the default home screen. IF you follow my instructions correctly the problem will be solved. You will not see that pop-up appear again. When you are on your phone make sure you are on the home screen. Click on the little circle to make sure (not the white one with 6 dots). You will need to have another page with apps opened so you can move them over to the right. On that page "not default" remove all of the apps except for one that way your will have two active pages. On the default home page move all of your apps over to the one page with the one app. Also move the widget with the time and location to that same page (second page). Once you do this the default screen will disappear. Click on the little circle to make sure that the default screen is no longer there. Reboot your phone. When you log in you will have a new default screen. Begin by removing all of the apps on the new screen except for one app. Then transfer all of the old apps back to the new default screen including the time and weather widget. The problem is now fixed. Open up as many apps as you can. You will not see the "android has stopped working" pop again. IF you need any assistants i will be happy to guide you.
