That will stop the ringing/vibrating, but it won't allow you to continue using your phone to do what you were doing before until the call stops/goes to voicemail.When the phone is ringing, press and release the volume button. That will stop the ringing and allow you to continue to use the phone. If the phone rings long enough, it will go to voicemail.
It happens every time over here. You get a call and there is no way to decline amicably. If you hit the "Send to Voicemail" the other person's screen changes from Ringing to "Declined". People even comment later that you keep declining my calls. If it is a landline that is calling, the ringtone changes from Call tone to Busy, thus informing the other user that you have declined. However, if you just don't pick up the phone, the caller gets the message "The Caller cannot be reached or is outside the coverage area, please try your call again later"
I'm quite sure I can do it since forever. It's more like a problem with CDMA network which is nearly not used in the entire world.The other annoying thing here is the lack of data when you are on a call. I mean its 2018. The network is so superior that it can handle 150 Mbps of download but yet you cannot use the data while on call.
They don't use the CDMA Network. Infact they use 4G LTE based delivery nodes. They have purposefully disabled that option and can only be enabled by the provider. Technically they are in the forefront but they have imposed a lot of rules.I'm quite sure I can do it since forever.
