16gb SD Card became 32gb after formatting??

So I bought a 16gb Sandisk Micro SD Card for my Android phone a few days ago. For some reason, when I tried plugging it in my phone and formatting it as an internal storage, it got corrupted. As I didn't want to go back to the place where i bought it since its was so far away from where I am, I just searched online how to fix corrupted sd cards. The result it gave me was through cleaning the sd card through the "Diskpart" program in computers and then making a new volume through Disk Management, so I did that.

Here's the weird part. When I opened Diskpart on my laptop, it showed 2 disks: Disk 0 which was my 1tb harddrive, and Disk 1 which was listed as 32gb. I was wondering where this came from since it literally says on the micro sd card that it only has 16gb. But since it was listed as drive E which was the assigned drive path for my SD card in the "This PC" tab, I concluded that it was the SD Card and not some other random drive. I just assumed that it was a temporary error and that it would revert back to 16 gb later on. So I selected disk 1 and cleaned it, created a primary partition, selected and activated that partition, then formatted it to NTFS (which took 2 hours for some reason) and moved on to Disk Management.

I just created a New Simple Volume through Disk Management and now the drive has been fixed. The thing is, it still says 31.24gb (roughly 32gb) free space on the SD Card. Even when I plugged it into my phone, it still said the same thing. The only drawback now is that I can only format it on my phone as a portable storage for "transferring photos and media" since it still gets "corrupted" if I try to format it as an internal storage (which I think was the problem from the start).

I'm not complaining since I just got a 32gb SD Card for the price of a 16gb one (it literally says 16gb on the SD Card so....). I'm just wondering if anyone can tell me how and why this happened and if there are other cases like this since I literally searched online for a similar situation and all the results are about people buying a 16gb SD Card turning out to be actually only 2gb or other similar things. None of the results mirror my situation. Any Ideas?

Do you mean copying it back to my pc and seeing if its still 20gb?

Yes. Seeing if there is 20GB of actual data.

The fake cards let you think you're copying the right amount of data, but it just rolls over and overwrites the beginning files.
But 16GB -> 32GB is not a usual scam size.
Typically, that would be sold as 64GB or 128GB, but it's only actually an 8GB card.

Yeah, I copied it back a while ago and it still says 19.6GB (or roughly 20gb ) on it, same with from what it said when i copied it onto the SD Card. Lol does that mean that i just got an extra 16gb for free?
