We want to customize the ROM of a Smart Watch (Model: DM368) having Android 5.1 OS inside with SIM Card. We want the watch to act as Tethering Watch with the ability to play the songs from its inbuilt storage rather than music stored on phone. The watch should be connected to both Phone and Bluetooth Earphone at the same time.
The ROM should have fixed number of apps installed with restriction of installing any app.
If user wants to install any app or watch faces then it should be only through an app which will be installed in the phone for setting the watch features like controlling the notification and tracking health parameters.
Currently the watch works as a phone since it has MTK processor with SIM card.
