I do experience lagging even on basic stuff like writing SMS or other-text inputs... (waiting 2-3 seconds for the soft keyboard to response). I'l have to do some Option->Reset when I find time... [iPhone 6+] Not good when you can't trust the device... once my iphone freezed for X seconds, then I realized that random social post were posted to FB, while I tried to touch the display... :) And that scares me :) I have to give a try to the "Reset" options :)
