It seems that one of Samsung flagship of this year, the Galaxy S6, it’s having some issues because of RAM management. At least this is what some members of XDA Developer Forum are experiencing.
Owners of Samsung’s latest flagships are reporting experiencing very aggressive RAM management by the device software, which means that the OS is constantly shutting down apps. There’s usually 200-400 MB of RAM left only at any given time, which means that it’s using almost 2.5GB of RAM at any given time.
These users have already reported this to Samsung, and there is hope that Samsung will actually fix this issue in an update. But there is a reply of Samsung UK, however unofficial because it was through social networking, which said that Samsung is aware of the issue and will fix it through updates.
