When my mobile phone memory card transmits something from the computer, the file will be damaged, and the transmission between Bluetooth will be fine. My memory card is Kingston 8G.

You can try "mobile phone fast transmission" to download files and directly search Baidu.

It only takes three steps.

1. Enter your mobile phone number.

2. Write down the information you want to send and select the file to send locally.

3. Click Send and enter the SMS verification code.

4. After the completion, the mobile phone will receive a short message, including the sent message and a short link to share the file. Click the link directly to download the file to your mobile phone.
