我刚刚在我的AT＆amp; t Galaxy S5中插入了一个新的16 GB SD卡。我正在努力格式化它，但它会问我一个PIN，我不知道这不是我的电话号码的最后4个，这不是我的最后4个SSN。请帮忙！
I just inserted a new 16 GB SD card in my AT&T Galaxy S5. I'm trying to format it but it's asking me for a pin and I don't know what it is its not the last 4 of my phone number and it's not my last 4 of my ssn. Please help!
The fastest thing to do is to insert the 16GB SD Card into another phone, a digital camera, or a computer SD card reader, and format it there. You'll get the job done faster than any other way.
If for some reason you are set on using a pin, you can try 0000, which works in some cases.
The code you have to fill in is the last pin you used for your lock screen
New SD cards are not encrypted by default. If it is encrypted, look at the SD card's manual/white paper for details.
But more likely I think it is asking for mobile's password as you are trying to wipe off all the data from SD card.
