Apparently, the screen touch sensitivity is pissing off lots of people too, over at Oppoforums. Even after changing the pressure sensitivity option under Accessibility doesn't fully solve it I feel. Hopefully this gets fixed in a future software update.
As for the accessories provided by Adix (purchased my set from there yesterday):
- Flip cover: maybe I'm not used to flip covers but it's not very user friendly. Hard to use one-handed, especially when got incoming call. Doesn't sleep when closed.
- Metal bumper: useless. When mounted, press power button, the little button on the bumper gets stuck, depressing the phone's button.
Have placed an order for a case from eBay, will review once received in about 2 weeks or so.
