I have a Galaxy S7 32gb. I know its old, but its still works like a dream. I have 8gb free space and keep my caches clean. My service is thru Verizon who I love. When i got the phone and set up on Verizon it had me use, i guess, their messaging app. Its great. Simple, intuitive and easy to use all around. But then i got a Galaxy 4 smartwatch. It refused to work with my messenger and forced me to install this. I h8 to say this, bcos in general i love google products, but this messenger is BAD.
