SD card issues

[Sarah8]

Having purchased my SD card (scan disk extreme 16 GB micro) brand new from argos to go in my Xperia M4 aqua. I am most disappointed that having transfered apps and other data on to it, suddenly today it has decided to malfunction. Several apps won't work anymore, and it is not recognised when re inserted - any help on this would be much appreciated

iPhone is a good phone. Highly recommend it  

However, for some M4 Aqua is just perfect.

Lollipop is not very stable with memory cards. I do not know why. When I had some apps installed to memory card, it happened from time to time that the phone lost the card unexpectedly. After restart, it was all good again.

But for couple of weeks there are no apps on sdcard and the problem has not appeared since.

The camera output I have directed to sdcard however - this way videos etc are there.

Of course, with many games, this is not the solution you are looking for. 

8GB M4 Aqua is not perfect for gaming, is not perfect for anything that requires lots of internal storage.

And since we are talking about it - do backups of your DATA as often as you can (the PCC backup is not super in this sense - it backs up apps (not all) but sometimes misses other data (program bug, i think - it is not related to whether you mark or not the folders)).

My experience is that USB is not reliable for copy-paste - thus I recommend using a good file manager that enables wifi copy.
