Is there a maximum size for an SD card for the P3S? Mine came with a 4 GB, but I have a 64 GB available. Just wondering if there is a limit for the P3S camera.

Correction!!! The P3S came with an 8 GB card.

i think i read somewhere that 64 is the largest supported. That does not mean u cannot use 128, but.. if things do not address properly it's not something DJI can easily fix...  And I think it's 64, maybe it's 32...  It used to even be a challenge to format anything about 36g, till few years back....

I'm using a 64 GB card in mine.  Not knowing the card you have, I'd just try it if I were you.  Format it in the camera and see how it works, if it's fast enough, should be no problem.

Page 28 of the manual says, "...supports Micro SD cards with a capacity of up to 64 GB. It is recommended using a UHS-1 or Class 10 Micro SD card to minimize the delay when reading or writing high resolution image files."

The P3S supports up to a 64 GB SD card with a UHS1, Class 10 rating. The higher write speeds, the better.

I tried a 2gb card, didn't work.

Class rating in not enough. I suggest U2 (better would U3), class 10 rating. U3 is the newer of the three but it's a bit overpriced. The U1, U2 and U3 designation signifies its guaranteed minimum transfer rate.
U1 means that it is guaranteed to transfer at a minimum of 10 MB/s, U2 20 MB/s and U3 it's guaranteed to transfer at a minimum of 30 MB/s. In summary I suggest, for P3S:  16 or 32 GB SD card with a UHS2, Class 10 rating!

A 64 GB SD card with a UHS1, Class 10 rating works well

Confident of my knowledge , I bought a 32GB Toshiba UHS-I microSDHC card, class 10 with UHS speed class 3 (see photos). With my huge surprise the card is not recognized by my P3S. I thought it was wrong so I did a test with "H2testw" software but it all ok. Tried on action cam, it works! Tested on a samsung tablet ... it works. Trying on P3S .... it does not work! So I used another 32 GB SD card (Transcend Premium) on the P3S and it works! Anyone can give me an answer?
PS. SD card format in FAT32

I use the exact SanDisk on the left (It was what my P3S came with) but in a 64gb. Never have had an issue. Also remember to set your video cache in the app. It's set to 2gb as default.

The card on the left is the standard one: 8 GB Class 10 - U1. The central one is 32 Gb Class 10-U1. The SD Toshiba is 32 Gb class 10 - U3.  It's guaranteed to transfer at a minimum of 30 MB/s, but unfortunately it is not accepted by the drone. I ask if someone has used SD class 10 - U3.
Many thanks
