Google confirms its latest update can scan all your photos to “use actual images of you and your loved ones” in AI image generation. That means Gemini seeing who you know and what you do. You likely have tens or hundreds of thousands of photos. They’re all exposed if you update.
Samsung has their own proprietary Camera app, and its own proprietary Gallery app. The Google issue probably doesn’t apply to you, but even though they’re better than Google options, you’re still locked in too.
Your mileage may vary depending on the third-party cellphone manufacturer, but everything I’ve seen (Google or Samsung based) has been locked in and paired on an OS that was once beloved for having interchangeable components.
