Why does the Xiaomi 15 Ultra have slow imaging or stuck in the Starry Sky mode?

Thank you for your support of Xiaomi products. The Xiaomi 15 Ultra has undergone strict professional inspection before leaving the factory, so you can feel confident in the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
In the long-exposure Starry Sky mode, the flash needs to converge AE before starting the exposure, and the convergence time is not fixed each time, resulting in inconsistencies in camera exposure, flash, and shutter countdown. It is recommended that you use the actual camera exposure and flash duration as the standard during shooting, which will not affect the final image. Thank you for your feedback, we will optimize this experience in subsequent iterations.
