Who has already installed the android OS, first you need to install ColeElec, and then only install Android TV (otherwise an endless splash screen at startup). By the way, switching on with the remote control does not work (I use 3 remote controls alternately). Voice search does not work, which makes it useless to use it as a TV box. Some minor problems with logging at the first start (for a long time it was not possible to log in, I saw the same problem on a pure android OS).
Another bug, it is impossible to enter letters in the native keyboard. Pressing the OK button does not select a letter, but selects a transition to another menu (everywhere except YouTube as there is its own virtual keyboard).
the air mouse does not allow you to select letters when typing (therefore, it turns out I did not manage to log in for a long time). If you insert a USB flash drive into the connector, after a while the wifi falls off. I only tested a couple of hours :(. Will have to come back to CoreElec again… disgusting software support (numerous bugs, without testing). I have another five-year-old android box for $ 20 and it works better (at least there is voice control), I don’t understand why here people write that everything works fine?!?
