@GrapheneOS Is there any way now or in the future to get graphene os on a pocket sized device (not the pixel tablet) without cellular? Any ways to securely remove those capabilities from a pixel?

@fredy_pferdi Cellular is integrated in a similar way as Wi-Fi and Bluetooth via an IOMMU isolated radio which can be reliably turned off. Samsung makes both the main SoC and the cellular radio. Not clear what you're trying to avoid. If you don't want to use cellular, use airplane mode.

@GrapheneOS @fredy_pferdi does airplane mode disable all cellular function including timezone and time setting?

Also, why do mobile OS's use cellular to set time instead of NTP or internet time like all other internet devices?

@shady_ @fredy_pferdi

It disables the cellular radio, so no functionality using it is available.

Also, why do mobile OS's use cellular to set time instead of NTP or internet time like all other internet devices?

That's not accurate. Android supports obtaining time via cellular, NTP or GNSS. The default is using cellular as the highest priority and NTP as a fallback. Cellular is more reliable.
