A couple minutes ago I was on a phone call, and after it ended, I noticed some big lag on my iphone 6+. It would take about 3-4 seconds before the actions I performed displayed, for example pressing power on/off, tapping/double tapping home button, etc. Just anything I did, there was a 3-4 seconds delay. I had to reboot the phone to get it back to normal. I was not doing anything before the phone call, all apps were closed in the background. Anyone encounter this issue on their 6 or 6+?
