What are some common issues when uploading files from Android devices using PHP?

One common issue when uploading files from Android devices using PHP is that the file may not be properly transferred due to encoding or formatting discrepancies. To solve this, ensure that the file transfer method used on the Android device is compatible with PHP's file upload handling. Additionally, make sure to set the correct encoding type in the HTML form that initiates the file upload process.

<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload File">
</form>
