Android dual SIM handsets - recommendations and reviews

[inquisitor]

Hello world,

I'd been interested in buying a dual SIM Android handset for quite a while but since most of them were of low quality or had subpar specs, I hesitated until recently when I ordered a Zopo C2/ZP980 (32GB ROM/2GB RAM version).
The only downside of the Zopo C2/ZP980 for me is its UMTS support which is limited to 850 and 2100MHz, a pretty pointless combination of frequencies as these occur together only in very few markets (afaik Australia, New Zealand, Thailand).

As you guys probably consider buying a dual SIM handset, too, here's my personal list of interesting devices:

• Zopo C2/ZP980
  The Zopo ZP980 and C2 share identical hardware, but the later comes with Alyiun OS, a Chinese fork-off of Android, preinstalled which makes it slightly cheaper due to subsidies
  + 5" 1080p IPS screen
  + MTK6589(T) quadcore CPU with up to 1.5 GHz (other versions come with 1.2 GHz)
  + up to 2GB RAM/32 GB ROM (other versions come with 1GB/16GB or 1GB/4GB)
  + microSD slot
  + neat iPhonish design
  + UMTS support for both SIM cards
  + changeable battery
  - limited UMTS frequencies and odd frequency combination (850 & 2100 MHz)
  
  
• Huawei G700
  + 5" 720p display
  + Cortex-A7 quadcore CPU
  + 2GB RAM
  + 8 or 16GB internal storage
  + microSD slot
  + changeable battery
  + high battery capacity (2150mAh)
  + cheap (~ € 240)
  - UMTS support only for SIM1
  - only dualband UMTS (900/2100 MHz)
  - only triband GSM support (900/1800/1900 MHz)
  
  
• ZTE Blade C V807
  + cheap (~ € 90)
  + changeable battery
  - no front-facing camera
  - no magnetometer (electronic compass)
  - only dualband UMTS (900/2100 MHz)
  - only triband GSM support (900/1800/1900 MHz)
  - generally low specs
  
  
• Samsung Galaxy S4 Mini DuoS (I9192)
  + 4.3" qHD sAMOLED display
  + quadband UMTS support (850/900/1900/2100 MHz)
  + microSD slot
  + GLONASS support
  - expensive (~ € 380)
  - battery not changeable
  - low battery capacity (1900mAh)
  
  

I appreciate your thoughts and recommendations on these and further Android dual SIM handsets.

Cheers
