Hidden Features on Google Map for Android

Google Maps (on Android Phones) Labs As it does with many products, Google maintains an evolving Labs section of experimental features in its Google Maps mobile app. The Google Maps Labs features vary based on what Google's working on at the moment, but right now you'll find four optional add-ons that you can activate:

Google Maps Lab #1: "Measure"
Google Maps MeasureThe "Measure" option in Google Maps Labs is probably my favorite of the bunch. You can tap the ruler and then tap any two points on the map, and Google Maps will tell you the exact distance as well as elevation changes between the spots.

Google Maps Lab #2: "Bigger Text"
The "Bigger Text" setting in Google Maps Labs is pretty self-explanatory: When checked, it makes the text in all of your Maps labels larger.

Google Maps Lab #3: "Directions Elevation"
The "Directions Elevation" setting gives Google Maps' walking and biking directions a little extra oomph: It adds an "elevation profile" to those directions so you can see the total ascent and peak of your journey.

Google Maps Lab #4: "Intersection Explorer"
The last Google Maps Labs option is an experimental accessibility setting that lets you explore maps by using a combination of haptic and spoken feedback.Android Power Twitter
So there you have it: the Google Maps Labs for Android.
