After searching on these forums and google, I plunged in and purchased a 64gb SDXC card for my S2 as most people had said the S2 works with it. However, the phone wont read it. Just says blank disc. I've tried formatting it in Windows both exFat and NTFS but phone still wont recognise. Phone software is up to date (4.0.4) so can anyone advise on what else I can do? Thankyou in advance.
