Nexus 5 App launcher changed to search option and frequently restarting after that

[AC Question]

my Nexus 5 android app launcher changed from sliding to search option and frequently restarting after that

Welcome to Android Central! I believe it was due to the latest Google App update. The new vertically scrolling App Drawer with the search bar at the top (I know, I don't like it either) is in line with the upcoming Marshmallow update.

The frequent restarts obviously shouldn't be happening. Try wiping the cache partition: http://forums.androidcentral.com/nexus-5-rooting-roms-hacks/352008-guide-nexus-5-recovery.html
