The issue where the POCO C71 shows "Lens is not available" when attempting to use the Camera on Google Translate is due to the fact that Google has installed a simplified version of the translation software, which does not support the camera function in its current form.
For your reference, here are more details of the issue:
1. This limitation is a result of the simplified version's design and settings, and it cannot be modified on the POCO C71;
2. To solve this problem, it is recommended that you download other translation apps from the Google Play Store to check if the camera translation function can work properly.
