Have you looked into blu phones? Very amazing. Sleek, and varied across the board. They have every price range from cheap to expensive.
Hardware most rum adreno 305 (lower end. Yeah. That's a pretty advanced and good processor for a mobile device) or snapdragon. Processor speeds vary a bit with some around 1.2Ghz, and easily overclockable once rooted. They all come unlocked (if you're not sure look into amazon or eBay, the blu company has their own seller account, at least on amazon that I am aware of). Also they use standard to high end cameras for both front and back, again depending on price range. Plus the screen sizes are easily able to give you what you're looking for. With of course dual-sim (whoever had mentioned they wanted one)
Software wise most run jelly bean I believe on 4.2 or above. Not fully sure on that so if I am mistaken don't take it out on them.
My mother and I wanted to give my step father a gift for his birthday. Jokingly we looked for high end expensive and amazing phones. We took an interesting time on it and we came across this company. And we bought one. AmaAmazing and it was about $150. Can't remember which one. After months of him using it and all of us being blown away by the phones capabilities, I took a wrong turn and messed with he kernel once rooted. The company replied to a support email I sent in a few hours and within 24hrs we had the problem fixed. Not long ago he upgraded and bought he "Life Pure" and in all honesty the phone has outperformed any phone and even some laptops at three times the price. Long post guys but this company really is amazing, but unlike apple or many others out there, they haven't been noticed as much. Its a shame really, if more people took a step back and looked into things, such as specs not just reviews or who has what, do a little research, and not bandwagon, you'll be amazed what you can get for the same or even lower price, and much more cutting edge and beautiful technology.
Not hating in any company. I own an Lg Optimud F3 plus an iPod touch 5th gen. Hopefully a "blu" soon too hope I helped
Here's a link to their website (Into Blu)
Note: no. They are not the electronic cigarette s company.
