Every phone is hackable but Pixel with GrapheneOS generally seems the hardest. See e.g. the leaked Cellebrite support matrix: https://discuss.grapheneos.org/d/14344-cellebrite-premium-july-2024-documentation https://discuss.grapheneos.org/d/14344-cellebrite-premium-ju... iOS generally seems harder than non-GrapheneOS Android, taking a few months for Cellebrite to catch up with.
