Here's how Messages will solve the low-quality media problem in RCS chats (APK teardown)

Google is too busy adding Gemini(and other AI features) to focus on basic useful RCS features. Like

High quality media

Dual sim RCS support

Its HQ compared to SMS with iPhones at least. I love it when I get blurry blobs of pixels.

From the screenshots it sounds like it already can send medium quality photos, this is adding an original uncompressed option. Even signal sends compressed images by default unless you switch it to HQ.

I've turned off RCS on my Android because it would often fail to send/recieve messages without warning. Same thing with my family. It's a step backwards for texting in my experience.
