Hi Guys, Phone 1; Ok so here goes...approx 10 days ago i was having problems with my aux port, when using apple earphones whilst making and receiving calls, I was also having problems with the phone crashing, i.e apps shutting down unexpectedly, calls freezing, calls being muted. Phone 2; So i take it into an Apple store (southland) Victoria a few days later, after a few tests nothing obvious shows up...so a new phone was given to me. Phone 3; Almost instantly the same problems arise, once I've restored etc. I take the phone back to same store and a new phone is given, this time I'm advised it could be my apple earphones, i didn't have my potentially faulty set with me so i purchased some that connect to the lightening jack, no issues as yet with lightening jack. Phone 4; Although no noticeable Aux issues were present, although i didn't even try because it was suggested it was faulty apple earphones, i did notice however that this phone i was given was not keeping charge for more than 5 hours, even though i trimmed down all the variable running apps etc, I took it back to Apple, reluctantly a new phone was given. and a new set of aux earphones swapped for new ones. Phone 5; The same aux problem, still cannot make calls on earphones and calls freezing crashing etc. Additional points; This all happening within a 10 day or so period. I use this phone to run a business and i am coming across very unprofessional with the freezing calls, muted calls and cannot have a private conversation (having to loud speaker) because i chose not to put the phone to my ear and only use ear phones for calls. Would love some help and feedback. hmmm...'genius bar' ?
