Since iOS 8, including 8.1, I hate Apple

.
Both my iPhone 5S and iPhone 5 are restarting whenever you need them more, i hate it too much now to detail all the problems, but here are some:
iPhone 5s:
- always restarts after few seconds when connecting to Pioneer car player USB port, did not before 8
- sometimes camera stops video recording, or locks, or focuses every 3 seconds in loop on video, not being able to start recording
- phone app sometimes locks playing the keypad DTMF tone until it self restarts
iPhone 5:
- phone shuts down randomly when battery level is below 30%, displays battery low at 28%
I'm seriously considering to leave Apple boat, even if I invested in more Apple devices building a hopefully working ecosystem.
I think that Steve is twisting in his grave by now considering the how bad things turned with all the latest Apple decisions.
