2 days isn't too bad. Just seems mad that Apple repair everything in store yet Samsung can't!
I broke the screen on my IPhone 6 Plus. I was kept waiting for several hours for service when walking in to try and schedule an appointment in person. That's because our online attempts to schedule an appointment with the Genius Bar failed repeatedly over the course of a few days due to some system problem they were having. I was given the option of scheduling for an appointment for the following week or hanging around at the mall and coming in after they finished with their existing queue. This is just to hand over a broken phone for repair. I didn't really need an appointment to speak to them about it. But you can't just leave a broke phone there. Papers need to be filled out and a loaner issued. So you do legitimately need a proper appointment for this.
It's just a bit maddening when you can't actually see people queued up for service and you see employees standing around you'd think could take your phone. But I'm not the troublesome type. I'll assume their procedures are there for a reason.
Then when I finally was able to talk to them about my iPhone they took it and I was kept waiting another hour longer, during which they determined they couldn't repair it in store after all, due to a systemwide problem with their calibrating machine. They gave me a 16 GB loaner while they sent my iPhone out to their depot for repairs. I got it back about a week later.
I was happy to have the loaner but all the waiting was a surprise because it's different than how it used to be, according to my husband who had needed Apple service in the past.
