As above. I have a Huawei P9 Lite. It's got an 8GB SD card in it. The card and my phone storage are filling up now. I've bought a new SD card - 64gb but I'm not sure how to swap them, ie. where to put the data from my old SD card.
I don't know whether to backup the data from the current SD card and then copy it onto the new card. I have my photos in Google Photos and I'm not sure how secure they are there. I have Lookout and know there is a backup facility there. Or should I pay for more storage with Google, or use another cloud photo storage facility, or put stuff onto a memory stick. Help!
