FW 2.177.00
September 24, 2026

What’s New

Redesigned Phone, Contacts, and Messages (SMS) apps with a refreshed look and streamlined navigation – including updated call, voicemail, and contact-card flows, a new compose experience, link previews, avatars, and improved search across chats and contacts.

 App Updates & Enhancements

  • Firmware Manager, security, and platform hardening – closed a security audit finding around the App Link verification file for the Firmware Manager app (assetlinks.json), preventing potential deep-link hijacking.
  • Enhanced Compatibility Layer – Significant updates to the compatibility core, providing smoother performance and improved support for third-party applications.
  • Refreshed Messaging, Contacts & Dialer  Experience : We have redesigned SMS, Contacts, and Dialer with a cleaner look and smoother, more reliable functionality throughout.
  • New UP Apps – UP Launcher (UP UI V15.3.18), UP Switch (V2.5.5)

 Bug Fixes

  • UP Launcher (UP UI V15.3.18) – Bug fixes and improvements.
  • UP Switch (V2.5.5) – Bug fixes and improvements.
  • “Compatibility core has stopped” error appearing frequently on FW 2.142
  • Media Playback Pauses When USB Charging Cable Is Connected. This is explicitly called out in the epic’s scope and is Done, but isn’t in your notes.
  • Custom contact notification tones reverted to the default sound once the SMS/MMS app was backgrounded or closed.
  • Unable to Switch to an Alternative Launcher- lynx on beta firmware 2.170
  • Fixed a “Compatibility core has stopped” crash that could occur repeatedly during normal app use.
