Hi, am about to get a new micro SD card for my Samsung Galaxy SII. Have used class 4 cards in my Galaxy Ace and HTC Desire and whenever I try to scroll through photos there is a delay as they render - fuzzy for ages before they appear nice and crisp - am really sick of this.  Not a card problem as have tried different cards in different phones and the same rendering delay occurs. Am now looking at a class 10 card for Galaxy SII as hopefully this will solve the problem.  Can anyone tell me how good the A-Data 32GB class 10 card is?  I'm tossing up between that and a Lexar 32GB class 10.  The Lexar is quite a bit more expensive than the A-Data - will get it if it is a lot better / more reliable but won't if the A-Data card is just as good. Have seen NZTeckFreak's comments about class 2 and 4 cards being just as good in terms of in-phone use but that hasn't been my experience - the rendering delays are really annoying and I want a card that fixes that issue. Thanks.

I'm confused by what you want :-)

You say you've tried different cards in different phones and they all have the same "rendering" delay .. but want a card that will fix it ?  What's to fix if they all do it ? :-)

It might not be down to the card speed at all to be honest with you, if your photos are high res and don't contain an embedded thumbnail then your phone has to open the file open and decode it, still going to take a moment to do that work as it's only a low power CPU afterall. 
The same goes if you are trying to see the photo full screen and scroll between photos, it might be showing you the fuzzy preview scaled up while it decodes the full res picture, or it might be doing a quick rough decode and then showing you the full res picture after a moments delay and decides that yes I do need to spend the effort on this one he's waiting ....

A faster SD card might help, but it's still a phone, not a Quad-core desktop computer, it's going to need time to do the math and display the picture :-)

Regards!

Doesn't matter how fast the card is...its all up to how fast the phone can translate the data and render the image.  I doubt you will see any significant change between class 4, 6 or 10 for that matter on a mobile handset

Ok thanks for that.  I still need to get a new micro SD card. Can anyone tell me what AData cards are like compared to Lexar as I am going to get one of those two. The AData 32GB class 10 is quite a bit cheaper than the Lexar but if the Lexar is a lot better, I'll spend the extra and get that - any opinions/thoughts out there? Thanks.

Try Quickpic, it's faster than the stock gallery.

For cards - I've no experience with the A-Data 32GB card, but I used to have one of their 16GB cards and had no issues.
