The introduction of Rich Communication Services (RCS) support in iOS 18 addresses a long-standing issue of low-quality image sharing between Android and iPhone devices. Previously, media sent from Android to iPhone often suffered from compression due to Apple's reliance on SMS texting. RCS allows for higher fidelity media transfer, aligning the messaging capabilities of both platforms.
For iPhone users, RCS is enabled by default in iOS 18. Users can verify this setting by navigating to Settings > Apps > Messages and checking that RCS Messaging is toggled green. On the Android side, users of Google Messages need to actively select the "HD" or "HD+" option before sending media. Specifically, selecting "HD+ Original Quality" is necessary to prevent compression and maintain the original file quality, as opposed to "HD Optimized for Chat".
Despite RCS improving image quality, larger files and videos can still face compression or exceed the RCS attachment size limit of 100MB. For these instances, alternative sharing methods are recommended. Options include using email or other messaging services. Google Photos is highlighted as a straightforward solution for users who have the app installed on both the sending Android device and the receiving iPhone, allowing direct sharing within the application.
