According to the update schedule posted by Telus the S10 will be getting Android 10 on December 16th. Fido/Rogers does not have anything listed for the S10 at the moment. The update can still be delayed so take this information with a grain of salt.
Yeah - But Rogers OS Update Schedule is only up to the 12th of December.... So there's that & Who knows if all the Carriers will release the OTA on the same day or even if Telus will release it on the 16th... I know that Rogers often misses their Update Schedule by a day or two 🤞🐧
I think it's legit. Latest build is CSKN, from November. In related news: S9, Note9 Android 10 final release for January here. Or Christmas if they feel generous. Android 10 is finalized for both and unless some showstopping bug is discovered, release is imminent
