Recent problems

Ever since the last update, i haven't been able to use my phone.

Abotu 2 weeks ago my phone wanted to be updated, and the update message kept bugging me so i gave in and updated. about 2 days ago black and white lines filled my screen halfway till they dissapeared. a few minutes later.
Yesterday, about 2 oclock int he after noon i wasn't connecting to any network, even though i was connected to my router, strangley enough i can still play apps without any problems that i would normally face if i wasn't connected to a router. For example the simpsons game requires yout o have an account and being able to connect tot he internet. it works still. but i can't receive calls or texts

Also, my phone has used 3 Gb of my data plan and it says its used up by a game i haven't had in over 2 months, a non existing game is using my data plan. I have no idea what to do View attachment 69477

This is what im facing "NO SD card" and "No network found"
