How about, you can't read data off the sd with out the phone now... that's a pretty big drawback imho...

 

Also if your phone breaks, you'll be losing any data backed up to the card as only that phone wool be able to access the card...

 

The card has the encrypted data and the phone has the key. Something as simple as a small issue where you call into customer service and they tell you to do a factory data reset is all that needs to happen to lose your data. Forever. No chance of recovery. Once that key is lost it and the data it secured is not recoverable and may as well never existed.

I don't have any secrets that require that kind of security. I don't even PIN or pattern lock my phone.

 

Same for me. I keep my phone with me. No need for high end security.

 

you will need both the SD and phone to access either data if im not mistaken. like Glen said, something as simple as hard reset, or wipe user data will cost you the data on the opposite device. so you wouldnt be able to ever flash a rom( if that happens for us) and keep the same sd card.

 

Phone encrypted, but sd card is not.

You can back up your data on your computer change cards. You can not undue encryption on the phone, not sure about sd card.

I'm in the water alot wadding, kayaking, rivers, lakes. If I lose the phone sdcard only has pictures. The phone has the data..
