We are habing some issues with authenticating and de-authenticating user with layer service for android sdk. The sdk is also missing some callback features for loading messages and conversation and the developer has to implement themselves or forking the code from git. Other problem we were having had to do with pending images. Review collected by and hosted on G2.com.
