Adam Krisko, Jan 31, 2018 : Hi everyone, We are starting to push the incremental roll-out of OxygenOS 5.0.3, our first official Android O OTA update for the OnePlus 5T. Changelog: System Upgraded Android version to Oreo(8.0) New design for Quick Settings General bug fixes and improvements Applied CPU security patch: CVE-2017-13218 Applications Updated Launcher to v2.2 Updated Gallery to v2.0 Updated Weather to v1.9 Updated File Manager to v1.7.6 For those who were on previous versions for OnePlus 5T, we appreciate your active feedback and attempts to reach out to us. With your help, we have been able to better optimize and improve several key areas. Thank you for your patience and as always, we look forward to hearing your continued feedback in the bug reporting forum here: https://forums.oneplus.net/feedback/. As always, this OTA will be incremental. The OTA will reach a small percentage of users today, and we'll begin a broader rollout in a few days. Your feedback is appreciated. We may not always be able to respond to every comment in the forums, but please be assured that we take your comments and feedback seriously. Hope you enjoy and let us know how you feel about the update in the comments below. Never Settle. EDIT: I'm adding two more things to the changelog: We've adjusted the volume for headsets to better align with European voltage regulations. It may seem a bit lower volume to some. We've added an APK called Mkey, this is a font resource that was provided officially for India for local font compatibility needs. This can be uninstalled by users if not needed or wanted, but we are required to provide it. 5.0.3 does not include Mkey.
