    this issue happens me so often
    everything is terrible since the last updates
    my galaxy was working fine til a coupple of months that I made the android update.
    Must be this a software problema or hardware?
    I made a Factory reset 2 times 1 month ago and worked well again all for only a few days then same
    After freezen when I turn back on it Works smoothly again but after a couple of hours of use is again back to the same

    Welcome to Android Central! There are two possibilities to consider first:

    1. Your SD card could be corrupt. Go to Settings>Storage, Unmount the card, remove it, and reboot.

    2. You may have installed an app that is causing the instability. Try booting into Safe Mode, which temporarily disables all 3rd party apps. If the problems go away, then something you installed is the culprit. It can be difficult to pinpoint though--you may have to uninstall apps one by one. Steps for Safe Mode at the bottom of this article: Reset: Samsung Galaxy S 4 | T-Mobile Support
