What smartphones have SD problems?

you sound like you are more interested in whos to blame. you forget to mention jellybean

 

I use a SanDisk Ultra 16gb on my Optimus L9, since updating to JB 4.1.2 LG has implemented the move to SD card feature and i've had no problems with the SD card.

 

Actually, I cant find the things I saved in my SD card too....

 

I have a class 10 32gb Sandisk card in my razr and it works flawlessly.

 

It's not an Android issue.

A few specific Samsungs have known issues with a few specific sd card models.

The Samsungs work with other cards and the cards that don't work with other phones.

Compatibility issues happen.

It's not a perfect world.

 

I've never had memory card issues across 4 differen brands, 5 different OS. I mean the old 2GB memory card I have still works and its older than my phone or tablet. Heck the 16GB card in my Tab right now is about 3 or 4 years old I think.

 

SD cards do eventually wear out, especially if one is taking a lot of pictures and erasing them repeatedly. I've never heard of any particular problems with Samsung phones and SD cards. There's a huge problem with a lot of fake SD cards, especially counterfeit Sandisk, which either just don't work at all or fail prematurely.

 

There are certain compatibility issues, the ones to avoid show up in a few of our Samsung device forums.

One that I recall is some models won't accept a card rated only as UHS-1 from SanDisk, only ones rated Class 10/UHS-1. That's the 64 GB example but there are others.

Meanwhile, last year's HTCs do just fine with a UHS-1 card, although not properly rated. I'm using one myself.

A few of the higher end Sammies are simply incompatible with a few cards. One will wear the incompatible cards very quickly.

Known issue, but not an Android one. I've yet to see it reported for other brands.

Counterfeit cards still pop up as well.
