Even do that the 2 phones run a 1.5 Gz dual processor, the LG Motion is way faster, has way more memory, better colors in the screen, better battery life and so far I have owned the LG Motion for 2 weeks and I'm amazed with it, the screen even that has such low resolution the icons, internet pages and pictures look amazing on it, also the camera on the LG is extremely good and it also has digital zoom, auto-focus, continuous shutter and the "Say Cheese" shutter to take pictures when the phone heard you say Cheese. I'm not getting crazy 4G speeds but it still flies online, most I got was 7.7Mb down with 4.7Mb up, least was 3.4Mb down and 3.5 Up.
There is a video on Youtube ZTE Avid vs LG Motion on Antutu Benchmark, you will see clearly the differences on that video, LG scored 12K+ and ZTE 7K+ and the colors on the ZTE look extremely washed out. http://www.youtube.com/watch?v=FLpFUJoqf5k
I will go with the LG Motion or an S3, coming from the Admire this LG feels like a Tesla Roadster.
BTW the Flash Player doesn't come installed, but you can download it at http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
Remember to go to your settings/security and check unknown sources in order to install apps that you didn't get from Google Play.
Good luck with your phone purchase
