Samsung is baking big camera firmware for the Galaxy S23 series?

Samsung is about to release a new firmware update for the Galaxy S23 series, which might bring major camera improvements. As usual, the company is testing new firmware builds on the Galaxy S23 devices before rollout to the Public via OTA.

Ahead of the release, a reliable source revealed that Samsung is preparing a big camera firmware for the Galaxy S23 series. Earlier, the same source claimed that the company may release a camera optimization update to its latest flagships in late March.
CheckFirm detected the latest test build for the Galaxy S23 Ultra smartphone, which bears PDA versions S918NKSU1AWC6 for South Korea and S918BXXU1AWC6 for India. Since the Korean builds appear to be a regular security update, the Indian build may be just the opposite.
Judging from the test build number, the Galaxy S23 series’ next global firmware may not only bring a security patch. As the bootloader alphabet has changed to U for Indian build, the next update is most likely to include under-the-hood changes such as rumored camera improvements.
Apart from the claims of the tipster, there’s no info available regarding Samsung’s next OTA for the Galaxy S23 series. As consumers continue to share their feedback and complain about emerging issues with camera performance and some others, the company will surely apply them in its future moves.
Galaxy S23 Series
Back in February, Samsung launched the Galaxy S23 series with Android 13-based One UI 5.1 software pre-installed. The devices bring improved camera capabilities such as better nightography and algorithm changes to deliver an enhanced photography experience.
The Galaxy S23 Ultra is the first Samsung phone, which is equipped with a monstrous 200-megapixel main camera. This sensor is capable of capturing photos in three different resolutions including a trimmed down 12-megapixel, a balanced 50-megapixel shot along with the full 200-megapixel resolution.
