What do I do if the focus is slow when taking pictures?

Please follow the below steps:
1. Check whether the issue still occurs when using third-party apps.
2. Clear the storage by going to Settings>Apps>See all apps>Find Camera>Storage&cache>CLEAR STORAGE and CLEAR CACHE.
3. Restart the phone.
4. After backing up your phone's data, restore to factory settings.
If the issue persists, contact the Nothing Support Team for further assistance.
