SW Version APHY v1.3.1 (V03.02.0373)Updated a month ago

Release date: 17/06/2025

This update is particularly important and specific for all users who rely on Sunrise, as it ensures the continued functionality of voice calls via the 4G network as the 3G network in Switzerland is being stopped for this carrier.
Fixes and Improvements

• Sunrise VoLTE Compatibility: Resolved a critical issue that prevented proper VoLTE operation when using a Sunrise SIM card.
  This fix ensures that calls are correctly handled over the 4G network, which is essential given that Sunrise has already decommissioned its 2G network and is in the process of phasing out 3G in Switzerland.

Known issues

• Voicemail: There is a bug that displays multiple 1’s on the Home screen when accessing voicemail via the shortcut (numerical key 1); if this occurs, go to Menu>settings>voicemail. If your voicemail number is displayed correctly, press the Punkt. key and save the number. If no number is displayed, insert your voicemail number manually and press the Punkt. key to save. Return to access voicemail by long-pressing numerical key 1 when your voicemail number has been saved.
• Alarms: After exiting the alarm application the phone can randomly return to the Time application when entering the Main Menu.
• Calling: The user can’t add “,” or “;” while placing a call to engage a pause or wait when dialing up.
• APN: While navigating an APN in editing mode, a menu item may overlay another menu item.
• Contacts: The 'Search’ field, which responds to numerical keys 2-9 for a quick search, will only register the first letter on any given key, making it impossible to search for names starting with the second letter corresponding to the key pressed.
