Hey, so basically i would like to suggest 2 things for the phone, they are both kinda related to each other, they both are big problems in my opinion, and my friends that i spoke to about it. Maybe they were both suggested maybe not but here they are.
1. Blocking a certain number from messaging/calling you. - Everyone has someone to block, lets be honest here, maybe an ex, an old friend that you parted ways, or someone just spamming you messages where the 2nd problems comes in - laggy phone from a lot of messages which take sooo much time to delete because the phone keeps lagging out. It could be just a command like /block /unblock (number) or something like that
2. Adding a way to clear your phone(messages) - the messages that clog up the phone take sooo much time to delete when the phone starts lagging after maybe 50 messages? And if you forget about it and let it go above, its just crazy how much time you need to delete 1 message not even talking about all of them. So the suggestion would be also adding a command or in the phone /clearmessages or something like that that would just erase all the messages instantly.
