Almost three weeks after opening the One UI 8.5 Beta Program for the Galaxy S23 series, Samsung has released the One UI 8.5 Beta 2 update for the lineup. This update focuses on fixing several critical bugs introduced with the first beta release.
The second One UI 8.5 beta update for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra is now available in India and South Korea. It comes with a firmware version ending in ZZDP and has a download size of over 700MB. It also includes the April 2026 security patch for all three phones.
