Three months ago I was mugged. I lost my beloved Samsung A3 and was stuck without a phone. I was willing to spend $350 dollars on a new one but I sure as shit wasn't happy about it. A colleague suggested I check out some Chinese websites. At first I was skeptical having heard my entire life that Chinese products were cheap but after some research I was convinced.
I bought a HT-20 pro for the cost of $170 dollars (including express shipping) that boasted the similar specs to a Samsung S7, a phone nearly $500 more expensive. That included 3GB of RAM and 32GB Internal storage.
https://www.tomtop.com/ & https://www.chinavasion.com/ are two trustworthy sites that I highly recommend if you're in the market for an upgrade.
