SD card limit says 8gb, Can I get a larger sd card to work? I'm thinking a buying a new phone, but it says the external sd card size limit is 8gb.  Can I do something to increase this to 16 or 32 gb.

Details:  phone: I-Mobile IQ 5.3

Android 4.2,  4gb rom, 1gb ram.

I don't want to root this right away.

The price is less then $200. unlocked.. Don't have $600.
Generally, you need to follow the max external SD card size limit. Otherwise, your phone might not be able to read the bigger-sized SD card.
