Have been using this one since March:

Many leaked OS's, no problems.

Not all memory cards (or USB memory sticks) are created equally. You get what you pay for.

ZERO BIG issue here as well as other have stated. 64 gb Micro SD Ultra Sandisk (red/grey) on 1055 working perfectly.

Same here. OP, did you do the routine "wipe" after installing 10.2.1.1XXX?

So last night, I reformatted (I think my problem was I was using NTFS) to FAT32 and everything seems to be working okay now.

Yes I did. Always wipe, never backup.
But oh well, got my issue fixed now, thanks.

For informational purposes, since I haven't seen the brand mentioned here, I am using the PNY microSDXC 64GB U1 on 1055 with no issues on STL100-4

No issues with my 64gb ultra. I did have to format it using my z10 before it saw it, though.
I'd suggest you try a mem card test program on your pc before trusting it again.
I backup my phone once a week and mem cards once a month

32GB SanDisk SDHC Class 10 working fine since Jan 2012. Although with the Z30 I've noticed pictures take a while to save

This one works perfect, have used on q10 and z30 since both devices launched with no issues.

They work as mentioned in so many prior posts.... it's formatting it in 10.2.1.1055 that is the issue... I know from personal experience

I will be formatting my new card on my g/f's 10.2 phone tonight

So last night, I reformatted (I think my problem was I was using NTFS) to exFAT and everything seems to be working okay now.

You got exfat working on 10.2.1.1055?

Fired from my 30cal.

[yueytan]

It should but I have not tested it. I know someone else mentioned it and it worked but it's easier to format the card on a PC or laptop.

If you bought the SanDisk Ultra 64gb sdxc it will have the adapter.

PLEASE NOTE:

AFTER YOU HAVE THE CARD FORMATED AS FAT32, DO NOT FORMAT ON YOUR PHONE IF YOU ARE RUNNING 1055. YOU WILL BE BACK WHERE YOU STARTED.
