   Hi @RobertApikyan, I run the camera example code on a Poco X3 NFC and the camera starts as expected. Is this the only device you're experiencing this issue on?

   Also, you appear appear to be on an older version of flutter. Can you try upgrading to the latest version of flutter to see whether or not you still experience this issue?

   Thank you

   @maheshmnj thanks for quick response, you are right the exception is the same, but please pay attention that I'm running the original example application from the library, the same sample works perfectly for the other devices, but not for the Xiaomi POCO X4 Pro 5G. Unfortunately, In the issue #29116 I can not find the answer for my question.

   Hi @danagbemava-nc thanks for the answer, yes this seems only for the Xiaomi POCO X4 Pro 5G. Ok, I will update the flutter to the latest version and let you know about results.

    Hi @RobertApikyan, please provide the output of flutter run -v that captures the exception and the list of devices you have tested on and whether or not they reproduce the issue.

    Thank you

    Hi, I'm also facing the exact same issue on Redmi 11 Pro + 5G. even the Camera example app not working from pub.dev
    Other third-party camera apps are working fine on that device.

    Same story, the latest version of the "camera awesome" library is working without any problem, however it seems abandoned, and the last update there was at Jun 2 of 2021.
