Unlock full Developer options on Philips PFK5500/12 I recently bought a TV with Android OS (Philips PFK 5500/12).
This is not the tiptop very best, I know, but it was okay.
Also this is not exactly AndroidTV, but merley a predecossor running Android 5.1.

I successfully enabled the developer options, via the easter egg, but left confused because I don't see all settings like installation from foreign sources and others.
As it is my understanding, those settings are there, but artificially hidden by the vendor.

So my qestion is wether there is another hidden option to choose or not?
After an update they are were just there.
