When I receive a call, if it happens to be a local call without the +65, no ID will be shown. It will show the number (so it’s not a service provider caller ID issue). I’ve reset my phone but that didn’t help. There are no apps on this phone that weren’t on my S4 (which worked fine). My previous S5, 900H, worked fine too. It’s not in the phone book settings or anything. If I rename a phone book entry and delete the +65, then when that person calls their name will show up.
