The built quality is actually better than I thought. However, real problem originates from the software.
First, the vivid launcher is not practical unlike its brilliant look. I personally suggest installing a Nova launcher immediately.
Second, you will likely need to fiddle with the factory settings if anything doesn't work for RAV4.
And the settings DO NOT work as they should. It prompts to reboot after each change, BUT the change will still not take effect after a reboot. You need to do something else to get it working.
Last, they still have not fixed the back over size issue and you need to unscrew the screen and shift down to fit. And still the back cover does not fit tight onto the display.
