TL;DR
- Final yr, Google started stopping units that failed Play Integrity checks from sending RCS messages.
- Google Messages would merely drop texts, with out delivering any errors or warnings.
- Messages now seems to be including an express discover when safety necessities usually are not met.
What’s extra annoying than when an app stops working? Effectively — a variety of issues, truly — however on this slender context we’re particularly speaking about when an app deliberately stops working, however received’t clearly talk why that’s. RCS help coming to Google Messages was a significant step ahead, not only for messaging on Android, however between customers throughout platforms, as nicely. Final yr, we recognized a difficulty with RCS in Google Messages the place your texts wouldn’t undergo, however the app wouldn’t let you know why. And now it’s trying like Google would possibly lastly be able to do one thing about that.
An APK teardown helps predict options that will arrive on a service sooner or later primarily based on work-in-progress code. Nonetheless, it’s potential that such predicted options might not make it to a public launch.
The issue that we noticed again then affected Google Messages customers that had rooted their telephones or have been utilizing customized ROMs — mainly, doing something that might trigger their machine to fail Play Integrity API attestation checks. If Messages detected that it was working on machine like that, RCS messages would simply vanish as you tried to ship them — no error, no falling again to common SMS, nothing.
We reached out to Google on the time, and the corporate described this measure as one undertaken to restrict the potential for dangerous actors abusing RCS, utilizing modified telephones to ship spam messages and the like. In that mild, the best way RCS was silently failing a minimum of made a level of sense — like shadow banning an account, it may be strategic to withhold data from an adversary. However harmless Android lovers simply ended up discovering themselves caught in that crossfire, and left with no clear indication why.
Quick-forward to now, and Messages appears to be on the brink of truly inform these rooted customers what its massive drawback is. Wanting via Google’s latest messages.android_20250730_00_RC00.phone_samsung_openbeta_dynamic launch of Messages, we’ve recognized a brand new textual content string:
Code
Your machine doesn't meet safety necessities
This can be a string that, as soon as the app begins utilizing it, ought to show in Messages RCS settings the place you’re capable of toggle on RCS and think about its standing — the identical place we’re anticipating the app to add that new Particulars button. Between the 2 of them, it feels that Google’s explicitly attempting to enhance its communication with customers in the case of RCS points.
Apps like Pockets already simply out and let you know when your rooted telephone is why it refuses to work, so it’s not like this represents a significant coverage shift for Google — we’re simply glad to see the aspect of extra data slowly beginning to win out. At this level, we are able to’t think about any critical spammers would acquire something from continued silence, and hopefully when this lastly rolls out we’ll have fewer customized ROM followers scratching their heads about vanishing messages.
