Install True caller app, it’s basically a phone and sms spam filter. It does other stuff too, but I just use it for that.
Most of the know numbers will never get to your phone. you’ll be notified that someone tried to call, so if it’s a mistake you can white-list them. Any new spam lines that do get through you can one press block them. If enough users block a number, it then gets put on the True caller auto blocked list.
It’s a good app. And free. You can pay, but the adds are very un intrusive, and they want £3pm to get rid of the un intrusive adds.
It use to be about £5 to get rid of the adds, which I would of happily paid. But not a subscription. The reason I didn’t true caller (with out adds) was backed into cyanogenmod, and I could never see myself moving from it. Rip cm.
