En la revisión de flatpanelshd de la x90 dicen lo siguiente:
Operating system & smart-TV
We have had a chance to examine Android TV on most of the devices that are available, including media players, game consoles, and TVs. Sony’s X90C uses the same processor as X85C does, so we did not expect it to perform better or worse. Sony has pushed out a few updates in recent months, but overall X90C is no different to X85C when it comes to Android TV and the general user interface.
This also means that the TV has its fair share of freezes/lag and even occasional crashes that force you to reboot it. The Android TV experience still not very polished and borders on the unacceptable in its current state. The problem is not that apps and menus do not work but instead that it is highly unpredictable. You never know for what reason it acts up, which can be quite frustrating as it makes you feel helpless. In its current state, you simple need to restart the TV at times, which is done by holding down the “power” button on the remote.
Of course, Sony has little to say on this matter. Android TV is Google’s project, but consumers will look at the TV and probably blame Sony. Developers have been invited to develop apps for Android TV but so far the selection is pretty weak. You have some of the most important apps such as Netflix, YouTube and Hulu, but many other apps, including HBO, are still missing. If you live in Europe, you can use HbbTV on the TV.
Que en resumen dice:
1.- el procesador que instalan es muy poco potente y no mueve bien el sistema operativo.
2.- El sistema operativo tiene muchos fallos y se cuelga mucho y es necesario apagar y encender la TV.
3.- El desarrollo del Sistema Operativo Android TV es responsabilidad de GOOGLE, es decir, las versiones las saca Google. Sony solo hace la implementación del Software. Están en manos de Google.
El error de sony, desde mi punto de vista, es haber elegido un sistema operativo como Android TV en el estado en el que se encuentra Android y dependiendo al 100% de Google y su política de actualizaciones y soporte. Ahora mismo estoy pensando en los teléfonos android y especialmente los nexus.
