Recently, Gionee released an upgraded version of the Gionee V188 called the Gionee V188S. Unexpectedly, this phone is being sold at the same price as the original, 1499 RMB (244.76 USD).
So, what is the difference between the two? The original version has support for a single SIM card while this version has support for dual-SIM and dual-standby. This phone has support for TD-LTE (China Mobile 4G), TD-SCDMA, and GSM.
Another interesting feature about the Gionee V188S is its battery. It uses a 5200mAh Samsung battery and can be charged via OTG. Although the rear cover can be taken off, the battery cannot be changed.
As for its other specs, the Gionee V188S has the MT6582 and MT6290 chips, 1G RAM, 8G ROM (can be expanded to 128G), a 5-inch 720p OGS screen, and a 2mp/8mp dual-camera. Its OS is the Android 4.4-based Amigo, and it has support for an e-compass and Hotknot. [source]
