Some security issues. Review on IMO

Imo is a best calling app in india. Why I say india because most of the cities and states not having 3g or 4g facilites so its well work in 2g networks more over it has 100 MILLIONS of download in google play store and famous amoung all people and most of the people specially student having account in imo.

Lets talk its features

Its features are ok as I am using this app for 8-9 months features are averge and you can also chat with friend or send any message but some time msg go in late I think its a network problem but I used in 3g net work so this problem occur while using imo for 8-9 month I see that no contract no. Is show thats really great I found in this only you see the name of the people who have account in imo . Some time I facing one problem during video call I call to some body at 2g network my cam video is not going but receving other cam video is showing that is the problem I am facing please short it out soon

Some issues

Security issue - some body call me but I can't block them I am not save there no. also but always showing there miss call on my notification when turn on the app I also search on net reguarding this issue but can't short out

Low quailty video calling - every time I see the quality of video calling is average and I think so its ok because in 2g network hd video calling is not possible to do

Other wise the app is good for indian user to go any place and do a video call at any network

Thank you
