Earlier this week it has been reported that Samsung was testing the new operating system that is Android 7.0 on two new smartphones namely Galaxy S7 and S7 Edge. This would be good news if the OS gets updated in the said handsets.
Outwardly it has been stated that the Android 7.0 update for the said smartphones will bring up the Grace UX to the devices. This would make the handsets same as the Galaxy Note 7. Moreover, the new user interface would be performing much smoother operations in comparison to the current software that is being added in the devices. The upgrade would bring up new feature and would also allow you to operate the same handset easily.
Now, this is all about the gossip or a rumour, which would be actually be counted when Samsung comes out and makes the announcement. Till then you need to wait and hold your breath.
