iPhone 6s camera issue
HI
its my second day for using iphon 6s and I have observed that camera is taking too much time to show display on screen. When I tap camera icon app executes, shows camera controls but display screen stays black n shows display after 30 seconds... It happens thrice during 24 hrs... Can some one share their valued input for this issue... Is it software issue or hardware? I didn't had a chance to use iOS 9.0 and 9.1 because when I turn it on first time it's updated to 9.2.
iPhone 6s, iOS 9.0.2
