    Hello,

    I've had my Samsung Galaxy S4 for a number of years, since it came out actually, but I noticed within the last month, the phone has been lagging, A LOT.

    The phone lags when I try to unlock it for use. I hit the home or power button and the screen quickly flashes on and goes off. I have to let it stay for a minute before it actually catches up with itself before I can unlock it and use it. Same when I try to lock it. I hit the power button and the screen freezes for a minute, and again, catches up with itself before locks and goes black.

    It lags when I'm texting as well. The screen freezes and can't type anything, and again, have to let it stay for a bit before the phone catches up with itself.

    Things to note or already tried:
    -Factory reset. Issues still remains
    -Photos, videos, music are all on the SD card (32gigs, 5gigs left of space)
    -Internal memory card has 3.9 gigs of space left.

    What could be causing this issue and how can I solve it??

    Thanks!

    Welcome to Android Central! First, try Unmounting the card (in Settings>Storage), then removing it and rebooting. A corrupt card can cause various issues.

    If that doesn't help, then see if it still lags in Safe Mode: https://support.t-mobile.com/docs/DOC-27781
