I have always travelled with a laptop for backup and review purposes. I will no longer have to do so because I have been exploring the absolutely amazing capabilities of my new Samsung Galaxy SIII smartphone. Before I get to the how-to (and entice you to read what is probably going to be a longer than usual post) here are some of the things you can do with an SIII, a couple of special connectors and adapters and things most of us already have (SD cards, USB storage sticks, USB hubs, portable hard drives):
1) Put your camera SD card into a carrier with a USB plug, plug the carrier into an OTG ("On the Go") cable and transfer your photos onto a microSD card (up to 64GB for sure, probably 128GB too) that lives inside the phone.
2) Configure the phone to automatically or manually copy your pics to the "cloud" through DropBox, SugarSync, SkyDrive or wherever you have storage set up. They can go directly from the camera SD card at the end of the OTG cable or from the "backups" that are on the phone microSD. (Even from a portable hard drive - details below.)
3) You can also plug a USB external hard drive into the OTG cable to move files from the drive to the phone and vice versa.
So if you have been following along you are probably thinking, "You mean I have to plug the camera card into that phone OTG thingy, copy pictures to the phone, unplug the camera SD card, plug in a hard drive then copy stuff from the phone to the drive??!!" Yes, that could be a hassle. Here's the really cool thing:
4) You can plug a POWERED USB hub into the OTG cable and have access to as many hard drives and SD cards as you have carriers and hub ports available! So with the USB hub plugged into the phone with camera SD card in one port and a portable USB hard drive (or USB sticks or SD cards) in another port you can copy files directly from the camera card to the hard drive or other USB storage media. You can even connect a Bluetooth keyboard/mouse to the SIII with a Bluetooth dongle in the hub!
So you have almost completely replaced the laptop functions with the SIII. It has a gorgeous 4.8" screen, but even with zooming and panning it is a bit limiting. The icing on the cake:
5) With a different adapter plugged into the SIII you can connect it to any LCD TV or computer screen that has HDMI input to see your photos and movies that are in the phone (or that you can stream with Netflix, Hulu, etc. - but I digress). Since there is only one microUSB port on the phone you can either manage files on external devices OR output to an HDMI screen, but not both at the same time.
And the final cherries on top:
6) The SIII has a fairly decent camera and lots of camera apps. Be sure to check out Sun Surveyor and if you're travelling to foreign lands with any newer Android phone you should install Google Translate.
Before I get to some of the nitty-gritty and gotchas (there are a couple) you might want to search for and watch a Youtube video that can be found with this string:
" Samsung Galaxy S3: Connectivity demo - USB OTG, MHL, bluetooth keyboards/mice, games "
by NZtechfreak at AndroidNZ.net. It is a long video and all the good stuff (for photographers) is in the first 7 minutes. After that he gets into all the game controllers and emulator software the SIII supports.
Hardware:
1) OTG - See picture for the OTG connector that works for me and source.
2) HDMI cable adapter - "Adapter HDMI EPL-3FHU for Samsung Galaxy s3" IMPORTANT make sure it is for SIII - the pins are different from the adapters for older Samsung phones.
Misc. Notes and gotchas:
SD CARDS AND HARD DRIVES
Any device that you want the SIII to see through the OTG adapter MUST be in FAT32 format. That is how SD and microSD cards are formatted up to 32GB. SD/microSD cards 64GB and above and the high capacity external hard drives (500GB and above) are exFAT formatted. If you want to put a 64GB exFAT formatted microSD into the SIII it will appear to work until you get to a certain threshold, then file corruption problems start to appear. (All the gory details are here:
http://forum.xda-developers.com/showthread.php?t=1698672 - BTW - I'm rajamar on that forum).
So if you do want to put a 64GB microSD in an SIII use this tool to format it from a Windows machine:
http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm I also had to use the above guiformat tool to reformat a Toshiba Canvio 500GB external hard drive that came with exFAT formatting.
POWER
If you watched the AndroidNZ.net video you saw the SIII dealing directly with the external Seagate hard drive that did not have any external power applied. This did not work with my 500GB Toshiba Canvio. The drive light came on, but there was no spinning sound, just head clicks. I had to run it through a powered hub.
USB hubs
Save yourself frustration and get a good powered hub. There are a lot of cheap options out there, but my experience and the reviews prove the low price is balanced out by high frustration. I have and recommend this: Plugable USB 2.0 10 Port Hub (with Power Adapter) at Amazon. It will even charge the phone while transferring files.
I know this is a lot to throw out all at once. But think about how truly remarkable this really is: with a cell phone, a $4 OTG adapter, a few USB storage devices of any capacity, a portable hard drive and powered USB hub you can have as much backup redundancy as you want including painless backup to the cloud while travelling.
If you're a photographer looking for a new or replacement phone you should check out the SIII - all carriers have them. One last note regarding carriers: if you are going to be sending hundreds of megabytes to the cloud pay attention to the data plan.
