Reset Galaxy tab without losing apps in SD Card I have an old Samsung Galaxy Tab, it keeps on lagging and has delays. I want to reset it, if I do will the newly reset Tab still acknowledge the apps stored in the SD Card? Thank you.
Short answer

No.

Explanation

One purpose of a reset, and why it's called factory-reset, is to set it back to the state it came from the factory. This means, all user apps and user data is "removed" (de facto, /data and /cache are wiped). Usually, only internal storage is affected this way, and SD cards are left untouched unless explicitly specified (I write "usually" as some manufacturers/ROMs deviate from this).

That said: your "apps on SD card" will be gone even without the SD card being touched, as:


app2sd doesn't move the entire app to SD card (but only parts)
Android would forget about those apps anyway, as information on packages installed resides in /data/system/packages.xml – and you remember, /data gets wiped by the factory-reset.
