Turn On Both Wifi and Wifi Hotspot
The device would need to have two separate radios to be able to do this.  


Radio one for the wifi client  
Radio two for the wifi accesspoint  


As phones cannot be upgraded with additional wifi cards, this is not possible.

(Technically it would be possible if the device had a USB-OTG capable USB port, but yours doesn't have this, and secondly the standard firmwares don't support such a setup either)
