SanDisk Extreme 4tb not detected by android phone.

I have just purchased a SanDisk Extreme SSD 4tb and my android phone just won’t work with it. I already own a 500gb,1tb and 2tb SSD SanDisk Extreme and have had no problems with any of them. If I connect it to my laptop it works but transfer speeds are abysmal. Any answers appreciated.
