I put in a new SD card on my galaxy s4 without turning off the phone.

    I didn't know you have to turn off the phone before putting in/removing a SD card.

    Would this cause any damage to the phone or SD card?

    Not to sure, but one thing I do know is you should always unmount your SD Card before removing it. Otherwise you could end up with a corrupt card. Who knows, maybe putting in a card while the phone is on can so the same damage.

    Putting the card into your phone while it's turned on is ok. You can even remove and replace with another card while it's on, but you'll need to unmount it first. Trust me, you can't damage the card by doing this since it's meant to be used this way (kinda like you don't need to fear about the damage when you plug/unplug an usb device into your computer while it's turned on).

    On some phones, they use the SD card instead of the built-in storage as the main SDcard partition. So you risk a lot of apps freaking out if you've moved them to the SD, or they disappear entirely.

    The low-end Huawei I had did. :eek: I never stuck one in my Skyrocket so I don't know about Samsung. If the phone wrote anything to the card, that would be an indication.

    Again, your apps would be freaking out if it was storing anything in the card. Like force closing.

    Interesting, I think one is able to move Apps to the SD card on the S4. I just recently did.

    Yeah, pretty much every Android phone can do that. But completely placing the extended partition, I have no clue. I think the newer phones don't even have the extended partition, like the N4 is just the 16GB entirely.

    If you weren't supposed to do this while the device was on then they would've blocked the SD card slot with the battery like they do with the sim card slot. Though since you can usually remove a sim card while a device is on I'm not real sure why that is blocked on the S4.

    not so sure about that.....if you remove the SD card while data is being accessed or written to the card it could corrupt the whole card and have to reformat. It could be an application or the system using the card in the background so the user might not be aware of it happening. It is always best practice to unmount the SD card or turn the phone off then remove it.

    Also....to followup with your analogy just because they don't "prevent" you from doing it doesn't mean it is the best thing to do......they don't "prevent" you from throwing it on the ground and stomping on it either....or dropping it in the water......just sayin...... :)

    Before removing your SD card...

    Settings>More (tab)>Storage>Unmount SD Card

    Wait for the phone to tell you it's been successfully unmounted. That's it. Do this and you're less likely to have problems with a SD card getting corrupted.

    Did you remove a card, or just put a new one in?

    If just a new one, no worries.

    Shouldn't be a problem if a card was absent beforehand.
