Hey, I just bought a 6S recently and noticed the GPS is quite inaccurate. When standing still the tracking will constantly jump around, and during navigation it keeps jumping around and stuttering. Does anyone else encounter this issue?

Not at all, I was in KL. Meanwhile my friend's iPhone SE was just fine which leads me to believe it might be a problem with 6S.

Hi, anyone here have experience dealing with Apple Service Provider?

I sent in my iPhone that i bought less than a month ago for GPS problems, here is what the navigation behaves like. Note that i never left the main road.

It has been almost two weeks since i sent my 6S in for repair and the center still say "waiting for response from Apple".

Called Apple support but they cant help as they say can't see what's going on with service center. Anyone have any advice how to proceed?

Thanks in advance.
