Where is live wallpapers,themes like other OS offer. Why the facilities which a mobile owner want to have do not get due to microsoft windows limitations,so why the limitations as per name of mobile's security? It takes a long time to give update of 8.1,all are optimistic. But what happens,after update we just get some bunch of faulty apps like this,made by Microsoft. If Microsoft co.develop this kind of faulty app,so what can be done by the app developers? Please look over on these matters. 1) 1st of all it's too slow. It takes time to show lock screen. 2) It shows missed call also as a star like message. 3) It fails to show other notifications specifically. 4) It has just limited pattern of lock themes. We love Microsoft & to use windows phone & don't want use other phones,so how we see others to have most best facilities,apps. Please update & fix all the problems for this app & also others
