如何在Android设备上启用Nexus 5（如触摸屏上的导航键）？我的设备是Xiaomi Redmi 1s运行Kitkat OS。而且，可以在没有扎根手机的情况下完成？
How to enable Nexus 5 like soft keys(navigation keys on touch screen) on android devices? My device is Xiaomi Redmi 1S running Kitkat OS. And, can it be done without rooting my phone?
Please check user manual Xiaomi Redmi 1S but based on my experience, you have to rooting your phone and install - check this site. download those softkeys collection from there. but make sure rooting your phone first just as we mentioned before. Dont forget to backup your data.
