Sent my 6P away last week via my closest 2Degrees store. Still waiting for it to come back.
Pro-tip: don't take your phone to a store, have them send you a courier bag haha. The girl in the store was perfectly nice but seemed skeptical about it being a straightforward problem that is well-known. So she gave me the usual "it can take up to two weeks blah blah" spiel which hasn't filled me with confidence.
It was much fast last year when I got the camera replaced, I dealt with Huawei and Fonefix direct.
