How to transfer photos from the Samsung C414 to computer?

You can take out your phone's memory card and insert it to your computer. It will appear as a removable drive in "My Computer" and you should now be able to make the file transfer.

Another option is by Bluetooth. You just need your computer to be Bluetooth enabled. If it doesn't have a built-in Bluetooth module, you can just buy a Bluetooth dongle from an electronic store for less than $20. Turn on Bluetooth for both devices, pair them and once paired, you should be able to transfer files.

Here's another option.
1. In Idle mode, select Ok > Settings > Connectivity > Select USB mode > Mass storage.

Mass storage mode allows you to utilize the onboard storage capacity of the phone’s microSD card to store and upload files. This option allows your computer to detect the phone’s microSD card as a removable storage drive.

2. Press Save.
