Unable to download / install application Android 4 (Micromax A110)

Hi

From two days I am unable to install or upgrade application on my mobile phone, application download starts and stucks around 15% or so and do not move further. I checked my play store settings and also I checked my internet connection and it is good and fine. What could be the issue ?

Anyone who is facing same problem, it was issue with internal storage, it was filled up and when I freed it up moving application to cards, downloads again started properly and also application started work easily.
