Upgrading your smartphone to the latest software version can set it free of bugs, improve performance, fix security issues, improve battery life and fix other problems.
However, many people prefer keeping their older firmware or software versions because of the large data download needed. But applying updates from an SD card can make it all so seamless. But first, what does “Apply Update from SD Card” mean?
What Is “Apply Update from SD Card”?
Applying updates from your SD card is simply using an SD card with the software to launch a newer edition of the Android operating system on your smartphone.
When you apply update from SD card, you’re doing the following:
- Sideloading the Android firmware from your SD card to your smartphone.

Google wants you to queue up for Android 13 and then the next…
