[Android Q&A, Help & Troubleshooting] Hi5josh:
Both phones are very good. If you are on sprint then its a given, just go with the evo. If your not then you have more room to play. However I would recommend the evo over the Samsung GS3. First Sprint gives true unlimited data and already has the evo, not the GS3. Giving props to the GS3 for the slightly bigger screen is a no-no. It is only a tenth of an inch bigger. Besides the bigger the screen, the more cpu/gpu power used. Speaking of that the evo has a snap dragon krait @ 1.5 GHZ dual core while the Exnos is @ 1.4 GHZ dual core. The Krait is a fairly popular CPU and is extreamly fast and responsive for its generation. It also in many other devices with have a large development behind them, therefore the CPU will be better tuned and potently have a higher overclock the the exnos. If you are concerned about ram, why should you be? The evo can easily run all applications that can be thrown at it including games. For the record virtual ram is available now.... (ya it wont be as fast enitialy, but what if they were to mount it to the rom instead of the standard class 5 micro sd card...) And if you enjoy gameing your in luck Htc's one line is the first 3rd party company to exclusively be accepted by Sony's playstation, allowing you to be able to play some exclusive playstaion games. The evo, in my personal opinion has a far superior build quality then Samsung's cheap plastic mat finish. When it comes to Customer care, support and updates, htc will surpass samsung. There are a lot of cool new software features such as S Voice on Samsung though, although a lot of people say they are lousy, and just another selling point to compete with Apple's precious Siri app. IF you are conserned about the batterlife, the evo has a larger battery then the GS3, and even though its non removable, it last a long time. I own it and im a power user. I cant stop using it. If you look at the popular devices section you will see mainly samsung devices, although the evo is on there and shurely will reach #1 as its original, the htc evo 4g did ,witch was the #1 device for well over a year. Development will pretty much be even though, maybe the evo a little beter, having a starting chance. There is so much more info that i could talk about but im starting to ramble on and on. When it comes to picking a device I look for the best device weather it is a brand name or not and the amount of potential development it will receive. That being said I pick the evo and would recommend it as the best Smarthphone on the market to anyone looking to buy a new phone! I know this may seem very one sided, but i did my research before choosing between the two (yes these are the exact to phones i was comparing before making a final decision). I own many samsung products and am not saying the GS3 is bad, just not the best choice. Give me a thanks if I have helped anyone with this matter, and if not, be mature and do not flame me or others providing information to help the general public! :D

It does have a micros sd card holder under the plastic portion under the top back of the phone that covers the camera, NFC, and all other antennas. You don't have to be tethered to a charger all day like many other smart-phones because the batter life is fantastic. Have you ever heard of Sedio? They are making a battery case for the evo right now. http://xdaforums.com/showthread.php?t=1667613 (all thanks go to the OP!) Sense is so well optimized that you forget its even there. All of the features you loved remain. It feels like AOKP/AOSP but with the option of adding sense widgets! :)
