- Mawonekedwe atsopano ogwiritsira ntchito ayambika—Home Launcher, yokongoletsedwa ndi zowonera komanso zokhala ndi lingaliro labwino la makhadi ozungulira (m'malo mwa windows). Mawonekedwewa amakhalanso ndi bar yotsegulira mwachangu, yomwe imakhala ndi njira zazifupi kuzinthu zomwe zimagwiritsidwa ntchito pafupipafupi, monga kupeza zoikamo ndi zidziwitso;
- Pulatifomu imasinthidwa kuti igwiritsidwe ntchito pamakina a infotainment yamagalimoto. Mwachitsanzo, imathandizira mawonekedwe azithunzi-zapawiri omwe amagwiritsidwa ntchito kwambiri pamakina omvera omvera;
- Zida zosinthira zosintha za firmware zimaperekedwa ( - Firmware-Over-the-Air), kutengera kugwiritsa ntchito ndi zosintha za atomiki. Chithunzi chonse chadongosolo chimamangidwanso ngati gawo limodzi, osagawanika kukhala phukusi lapadera. Zosinthazi zimakhazikitsidwa pazigawo ziwiri zamakina, imodzi yomwe ikugwira ntchito, ndipo inayo imagwiritsidwa ntchito kukopera zosinthazo. Zosinthazo zikakhazikitsidwa, magawowo amasinthana maudindo.
