The app needs to improve! – Z5 Mobile Review

Why not you guys update the app with full-screen notification without login just same concept to Sorenson VRS did to its app. I want this app same to SVRS app, which will be easier for us to receiving call from someone important instead missed calls and have to access login the app. Please do it!!! I mean it!
