Look at your SD card SD card Not all Androids have one, but if you do, a messy slow SD card can really make your Android chug. We can fix that to some extent. What we want to do is backup the card, format it so that it's clean and ready, then put our files back into place. The easy way to do this is with a computer. Warning — you can lose game progress, app data, coins you paid real money for in Tiny Tower and other things you may not want to lose by doing this. If your favorite application doesn't use Google Cloud save, think about this before you do any tapping clicking or popping. Power down your Android, then take the SD card out of the device. Place it in an adapter so that it can go into either an SD card slot on your computer or into a free USB port on the computer, and insert it in the appropriate hole. Your computer will take a second then mount it so that you can see all the file on the card itself. Next, make a folder on your computer desktop to put all the files in. Name it something you'll remember, like sd-card-backup or the like. Using the file manager on your computer, copy all the files from the SD card and paste them into this new folder you created. Double check that they are all there. Then triple check that they are all there. Once you know all the files were copied, unmount the SD card from your computer and pop it back into your phone. Fire up your phone, the dive into the storage section of the settings again. This time, we're going to format the SD card. This wipes all data off the SD card. Make sure you have everything backed up, or you'll be sorry. Go ahead and format the card, then power the phone off again. Pop the SD card back into the computer and open the backup folder. Go through and delete anything you know you no longer need, but be sure you don't need it first. I have three DVD images for Red Hat on the SD card in my Note 3. Those don't need to be on my phone, so I wouldn't copy them back over to the freshly-formatted card. Err on the side of caution here, and if you don't know what a file or folder is, copy it back over. Once you have everything you want and need copied back to the SD card, place it back in the phone and power it back on. Once everything is up and running again, go into the app drawer and say "Dammit, Jerry, what happened to my apps!?" Some of your apps were partially installed to the SD card in a secure image when they were installed. Find those apps in Google Play and reinstall them to fix it. Pro tip: This step is sort of a pain in the butt. It also can make a huge difference, so it could be worth doing. Either way, it's not something you want to do very often, so think about upgrading that SD card when you do it. This is a perfect time to move to something faster and bigger than that Class 4 16GB card you bought when you first got your phone ...
