Today I went to an apple store 4 times! Went there at 9:30am with no appointment, was told the next available appointment was 12:40pm. I am to blame, so I went to the gym came back 12:30 waited for 20 mins then the apple genius got my phone and told me they need to change the front screen of my phone and its gonna take 45 mins! So i went around the mall for 45 mins then came back and got my iPhone with a new front screen, tested the camera while at the store, seems to be working fine. Went home and to my surprise the touch ID is not working reset my phone tried to enroll my fingerprints again got an error message. Went back to the apple store @ 3;30, next available appt is 5:40!!!! So I went home AGAIN! came back at 5:30, apple "genius" tried to fixed my phone and finally gave up and exchange my phone with another one which was not brand new! I was too spent/exhausted to complain! atlesat now the front camera is aligned, the rear camera does not rattle when shaken and the touch id works! what a day!
