Google is again sending a message to Apple: Fix the text messaging issues between Android devices and iPhones.

For years, consumers have voiced their annoyance over the handling of text messages on smartphones between the top two messaging platforms: Apple's proprietary iMessage and Google's Messages app, which uses Rich Communications Services (RCS).

Both platforms supercharge regular text messages — allowing for features like higher quality images, read receipts, text effects, enhanced security, reactions and other benefits. But because the platforms aren't compatible, text messages between iPhones and Androids revert to regular, outdated text messages.

This lack of interoperability leads to a major annoyance, for some. Texts from Android devices to iPhones show up in a green bubble on an iPhone while iPhone to iPhone messages arrive in blue bubbles (standard texts show up in light gray on both platforms).

Messages between Android and Apple phones are turned into SMS (Short Message Service) and MMS (Multimedia Messaging Service) texts, which Google charges are "out-of-date technologies from the 90s and 00s." As a result, images sent in messages between Android and iPhones are compressed, Google says, and users can't tell if see if messages have been received and read. Google has claimed this distinction leads to "peer pressure and bullying" in favor of iMessages and iPhones.

Google is going on the offensive again with a website encouraging Apple to adopt RCS so the messaging systems interoperate.

"It’s not about the color of the bubbles. It’s the blurry videos, broken group chats, missing read receipts and typing indicators, no texting over Wi-Fi, and more," Google's site declares. "These problems exist because Apple refuses to adopt modern texting standards when people with iPhones and Android phones text each other."
