Sorry for your loss,
As for pattern combination there are alot of possibilites, commonly used patterns are usually ZigZag , L , S , G , etc.
But that is if you get lucky and unlock the phone, But it's game over if you ended up blocking your phone from excessive failed logins.
Samsung A12 can be unlock by your local technician but i'm pretty sure data would ended up being erased as well.
That ends up only with unlocking the phone by luck , or try repairing the Huawei's LCD ( which isn't guarantee that it won't be protected by locks ).
Couldn't be much of a help, Sorry.
