Home Button isnt working

[SofiMicaella]

My home button isnt working which means i cant take screenshots. I used to be able to take screenshots though. I downloaded many screenshot apps but they say i dont have a root or something like that. I tried restarting amd shutting down my galaxy core multiple times and it hasnt fixed it. It started not working around 2 months ago. I used to have my phone on a case that was too small for it so i dont use that case anymore since ive read that that may be the reason to my phone home button nit working but i havent had it on a case for two months now and it still doesnt work. Can anyone please tell me how i can fix my home button without having to renew my phone? Please??? I really wanna take screenshots. I use thr other buttons to go back to the home screen and to turn my phone on so the only reason why I want my home button fixed is so that i can take screenshots. Thank you!
