After update to my iPhone 6s Plus.. so far no issue at the moment (touch wood)... quite enjoy it...
So far I liked it as well, but there's 3 bugs? that I noticed
-keyboard
After ... there's no caps like last time.
After going to the numbers and symbols window, previous version will change back to alphabet after space but after update, it remains in that number and symbol window.
-launch app from notification
After received whatsapp message, I can only 3D Touch the notification to quick reply window den tap to launch app but if I receive more den 1 notifications, I'm able to tap and launch the app through the 2nd message.
-App Store
At the updates window, I cannot leave reviews.
