My sister has purchased a Xiaomi Redmi Note 3 smartphone. We would like to know how to use the scan feature to scan a document. When we click on the scan tool, it shows on the screen 'Place code inside the frame below'. What code is being referred to here? There is also 'Torch' and 'Photo' at the bottom of the screen. When we clicked on 'Photo', the options came to save it and we chose 'Gallery'. However, we could not locate the photo in the gallery. We are thoroughly confused and hence seeking expert guidance here.
We would like to have step by step guidance on how to scan a document using the scan tool on the smartphone.
