Google Labs Layers 
The Google Labs layer is shown to the right. It is a 
collection of experimental features you can turn on 
and off. They’re not always reliable, and they don’t 
always last, but some Google Labs “graduates” have 
turned into solid and popular features, such as the 
public transportation directions in the Google Maps 
app. 
Most main Google products have their own set of 
Google Labs experiments, and quite often (as in 
Gmail) those features just won’t work on your phone. 
Google Maps is an exception to this general rule. 
Follow these steps to toggle Google Labs layers on 
or off: 
 
 
1.  To get to Google Labs, press the Menu button while in Google Maps. 
2.  Tap More. 
3.  Tap Labs. 
4.  Tap on individual layers to toggle them on or off. You can enable or 
disable layers at will. 
Google does use the relative popularity of Google Labs projects as one factor in 
determining what stays and what goes from an application or service.
