I went apple service centre just now, they say they do not do repairs for sets out of warranty and quote me $450 to change for a new set with 3 mths warranty.
I hv not backup my phone, I got no choice but to seek 3rd parties repairs.
I am not trolling, but I am so peeved why you guys keep on resorting to 3rd party repairs.
Please follow what Food_Lover posted, do the basics!
1. Restart the phone.
2. Restore the phone and ensure its running iOS 8.3, do not restore from backup and monitor.
3. If all fails, its a hardware issue.
Its $450, BUT its at least an official tested QC Apple Replacement Unit dude.
Don't understand why you all like to risk 3rd party repairs just to save $200.
Choice is yours at the end of the day.
