GrapheneOS supports [sandboxed Google Play](https://grapheneos.org/usage#sandboxed-google-play), which runs Google Play Services fully sandboxed like any other regular app. This means you can take advantage of most Google Play Services, such as push notifications, while giving you full control over their permissions and access, and while containing them to a specific [work profile](../os/android-overview.md#work-profile) or [user profile](../os/android-overview.md#user-profiles) of your choice.
[Google Pixel phones](../mobile-phones.md#google-pixel) are the only devices that currently meet GrapheneOS's [hardware security requirements](https://grapheneos.org/faq#future-devices).
[Google Pixel phones](../mobile-phones.md#google-pixel) are the only devices that currently meet GrapheneOS's [hardware security requirements](https://grapheneos.org/faq#future-devices). The Pixel 8 and later support ARM's Memory Tagging Extension (MTE), a hardware security enhancement that drastically lowers the probability of exploits through memory corruption bugs. GrapheneOS greatly expands the coverage of MTE on supported devices. We cover how GrapheneOS's implementation of MTE differs from stock Android's in our [own article](https://www.privacyguides.org/posts/2025/09/20/memory-integrity-enforcement-changes-the-game-on-ios/#:~:text=The%20Android%2Dbased%20GrapheneOS%20also%20uses%20MTE%20to%20a%20far%20greater%20extent%20than%20stock%20Android).
### Connectivity Checks
By default, Android makes many network connections to Google to perform DNS connectivity checks, to sync with current network time, to check your network connectivity, and for many other background tasks. GrapheneOS replaces these with connections to servers operated by GrapheneOS and subject to their privacy policy. This hides information like your IP address [from Google](../basics/common-threats.md#privacy-from-service-providers), but means it is trivial for an admin on your network or ISP to see you are making connections to `grapheneos.network`, `grapheneos.org`, etc. and deduce what operating system you are using.

Secure Elements like the Titan M2 are more limited than the processor's Trusted Execution Environment used by most other phones as they are only used for secrets storage, hardware attestation, and rate limiting, not for running "trusted" programs. Phones without a Secure Element have to use the TEE for *all* of those functions, resulting in a larger attack surface.
### Hardware Security
Secure Elements like the Titan M2 are more limited than the processor's Trusted Execution Environment (TEE) used by most other phones as they are only used for secrets storage, hardware attestation, and rate limiting, not for running "trusted" programs. Phones without a Secure Element have to use the TEE for *all* of those functions, resulting in a larger attack surface.
Google Pixel phones use a TEE OS called Trusty which is [open source](https://source.android.com/security/trusty#whyTrusty), unlike many other phones.
