krcavojt, Feb 10, 2019 : Dear Community, Internet only mode is an option in "Wireless & Networks" settings menu. It allows the user to turn off the cellular networks while maintaining internt access via 4G networks. Who are the users? Anyone who needs to shut off calls and SMSs while staying connected to internet. There might be 2 reasons for doing that: (1.) Save battery, (2.) Less interruption. This is showed on examples in section "What is the user value?". What is the proposed function? This mode shuts off call and SMS cellular networks (2G or 3G) and maintains the 4G network for data transfers on. What is the user value? (1.) It is handy in emergency situation when you need to look for directions on a map or you wait for important Whatsapp call or you answer business emails but your battery is almost flat. (2.) It is also great for scenarios when you need to focus on writing emails or focus on Skype conference call and you don't want to be interrupted with calls or messages (Even in silent mode the call still shows on the phone). If there are existing comparable functions in the smartphone industry, how is your proposed feature superior? There is a possibility to block incoming calls but the phone still receives SMSs and it still drains the battery because it doesn't shut the cellular networking off. Same functionality could be achieved by using the airplane mode and turning the WiFi on. But this only works when the WiFi is available. This exact feature has never been implemented in the industry. It is a feature that could make OnePlus phone experience more pleasant. DIAGRAMS: Scetch 1: Shows the implementation of the toggle for Internet only mode in Wireless & Networks settings menu. Scetch 2: Shows the main idea of this mode. There are currently used icons for connectivity on the left and a proposed new icon on the right. There is a couple of design options for this new icon. It shouldn't be hard to implement this feature. From frontend point of view: It only adds one toggle into settings and one new icon to notifications bar. From backend point of view: It is already possible to switch between certain networks and therefore it should be easy to just allow 4G and turn other networks off.
