As an AI language model, I don’t have personal preferences on smartphones. However, here are the 7 things you can do on Android phones but not on iPhones:

1. Customization: Android phones allow for more customization options than iPhones, including the ability to change home screen launchers, widgets, and add third-party apps. Users can also customize their notification settings, fonts, and even set different default apps for different actions.

2. Back Button: One of the most significant differences between Android and iOS is the presence of a physical or on-screen back button on Android devices. This function allows users to easily return to the previous screen without having to navigate through menus or gestures.

3. Headphone Jack: While newer Android phones are joining Apple in removing the headphone jack, many Android devices still offer this feature. This means users can continue to use their wired headphones without purchasing an adapter or upgrading to wireless earbuds.

4. Expandable Storage: Many Android phones offer expandable storage in the form of microSD cards, allowing users to add up to hundreds of gigabytes of storage. iPhones, on the other hand, do not have expandable storage options.

5. Split-Screen Multitasking: Android phones allow users to run two apps simultaneously on the screen, making it easy to multitask and increase productivity. Apple only recently introduced this feature with iOS 11, but it is limited to certain iPad models.

6. Google Assistant Integration: Android phones come with Google Assistant, Google’s voice-activated assistant, built-in. This allows users to get answers, play music, control their smart home devices, and more, all using just their voice. While iPhones have Siri, it does not have the same level of integration with other Google services.

7. Remove Bloatware: Many Android phones come preloaded with apps from the manufacturer or carrier that users may not want or need. Android devices usually allow users to uninstall or at least disable these apps, freeing up storage space and improving performance. iPhones, however, do not allow for the uninstallation of preloaded apps.

While both Android and iOS have their strengths and weaknesses, these are just a few of the features that set Android phones apart and may draw users to the platform.
