Same here on my iPhone 6S:
- Apps freeze and then crash 80% of the time when opening or switching to them
- Huge memory leaks when trying to open the apps causes battery to drain quickly
- Cannot hear people who call me 50% of the time
- Sometimes when the phone freezes it goes to a black screen that I cannot come out of, even the off button doesn't work. After 5mins it becomes responsive again.
- iTunes controls from lock screen usually don't work, break sometime after restarting phone
- Many notifications just come through as a vibration, nothing on screen. Occasionally they appear for a moment and then disappear
EXACTLY the same issues happen on my bros phone, he BOUGHT A NEW PHONE because he thought it was broken. And the SAME issues happen there too......... How are more people not reporting this?
I am a software dev and this is just shameful that such a buggy OS could be released, which only needed to support a couple of handfuls of hardware variations :/
