Try opening 5 apps at once and get back to me on that. Example: I have a LG G2x Dual core and if I open dolphin browser and 2 youtube apps forgetaboutit it is freeze and slow crawl. Or even dolphin browser and stock browser and anything else or any combo of any 4 or 5 apps it's just f'n lame slow crawl freeeze. It's that lame arse.
