Nexus 5 Marshmallow Problems
The reason we recommend so much prep work is because of the Nexus 5 Android Marshmallow problems that are swirling around right now.
In the week since the update's release, we've seen a number of Nexus 5 users run into Marshmallow problems. While we haven't heard about any widespread bugs, we have isolated complaints about battery life, connectivity, apps, random reboots, lag, and more.
We don't know when Google will release its first bug fix update. That's why we recommend doing some prep work before you install Marshmallow.
