Well guys I bought this phone on August 2015 and I also felt the internal memory shortage problem. So I rooted my device and removed apps those are not required for me, even it's default launcher is about 10 mb , I replaced it with 1.4 mb launcher. My phone running well as I can with apps like fb messenger, hike, whatsapp, IMO etc. Sorry about the camera quality.
Worst phone I have ever used, you can't install any apps unless preloaded. Even apps never been used, if you extended your memory.
