Title says it all. What else than calling/messaging do you use your android phone for? I use mine for: Browsing the internet/social media. (like GBAtemp, twitter and youtube) I use DriveDroid, for using my phone as a bootable USB I use it for storage (things i need to have with me. although only the most important stuff) I use it for listening to music. A lot. I use it for emulators! My galaxy s6 is more than capable with 3 GB LPDDR4 ram and an 8-Core 2.1GHZ Processor. I use it for tinkering. like custom roms, and stuff like that.
