If you choose to keep with the default and store photos and videos on the SD card, you'll notice that the Gallery creates a separate folder for those images from any previous captures to the internal storage of the phone. The first time you launch the camera app after inserting an SD card you'll get a warning letting you know the fact, and if you don't want photos and videos saved to the card it's a simple switch in the settings. Since you can't move every app to the card, it makes sense to start storing pictures and videos there, and that's just what the GS7 does. When you put an SD card in your Galaxy S7 or S7 edge, the phone is set up to utilize that extra storage right away. Pictures and video save to the card by default Nothing to lose any sleep over, but one to be aware of nonetheless - you may run into a couple small pain points (or simply some waiting) by removing the SIM every time you remove the SD card.
Every time you remove and replace the SIM the phone will take a little bit to re-connect to the network and negotiate things, and in some cases that'll require a reboot of the phone if it's been a while. That means if you're going to want to use your phone for calls and data while the SD card is out, you'll have to replace the tray with just the SIM - and then, of course, remove the SIM once again to put the SD card back in the phone. Even though you're more likely to want to remove the SD card for data transfers to/from a computer than you will remove your SIM card, in this instance you don't have a choice - removing the SD card is also going to pop out your SIM. This doesn’t mean the SD card is useless(you can format it), it just means the data stored on it cannot be accessed.In an effort to simplify things, Samsung uses one slot in the body of the Galaxy S7 to hold a single tray with both the SD card and SIM card in it. You should also know that if you ever do a factory reset on the Galaxy S7, you’ll be unable to access the data on the SD card.
You just can’t access the data on another phone, tablet, PC or any other device that accepts microSD cards. This will still keep all of your data accessible on the Galaxy S7 or S7 Edge(the same S7/S7 Edge you encrypted it with). Now, you can take the SD card out of the device and put it back in at any time in the future. Once it’s done, you’ll be told that the process is complete and then you can go about your business. The amount of time that it takes to encrypt the Galaxy S7 SD card will depend entirely on how much data you have on it. When you’re ready, go ahead and tap on the Encrypt SD Card button that is at the bottom of the screen and let the Galaxy S7 or S7 Edge do its thing.
You’ll probably want to read the warning/information here, but it’s basically what I’ve already told you. You’ll want to scroll down and tap on the Lock Screen and Security option and then from here, scroll down and tap on the Encrypt SD Card option that you see in this menu. If you’re ready to take the plunge though, then head into the Settings application on your Galaxy S7 and S7 Edge. So, if you like to keep all of your music on your SD card so you can swap it out from device to device then do not encrypt the SD card. As mentioned above, please make sure that you understand encrypting the SD card means you cannot access the data on the SD card from other devices. My goal is to introduce you to this specific feature so you know about it and you have the option to enable it if you want to. I’m not here to convince you one way or the other though. Most people are either really pro-encryption or they are against it. Then Tap on the ‘Encrypt SD Card’ Button at the Bottom.
Scroll Down and Tap on the ‘Encrypt SD Card’ Option.Scroll Down and Tap on the ‘Lock Screen and Security’ Option.You’ll see this information before you actually encrypt the Galaxy S7 SD card, but I just want to make sure you understand this before you proceed. I do want to note though, if you encrypt the data on the SD card in the Galaxy S7 or S7 Edge, then you cannot access that data on any other device.
