Tango pretty old app for video call and thats gives more space to create new friends all over the world. If are in the park of sone where u can discover nerby tangi users and chat with them. While using send so many reports to tango suddenly app closes. Personally i dont like the colour pretty hard to see the dark orange colour for long. But about the features much better video audio, sharing, chatting, games, free phone calls and news feed. Some times when i m checking with someones news feed they keep promoting the games thats not ok. Video calls not ok with mobile data connection even with wifi sometimes can crash. Voice calls also same. When i m making new friends other countries i asked theirs opnions about the app most of them said they are happy with this app. Now checked with google play review one long time tango user (about 4.5 years) he mentioned about the app is earlier days tango video call quality is awesome when new versions comes not ok at all. Another new tango user said that app pulling more data and heavey to run same thing happens to samsung galaxy s4 user also. Hipanda can give 2.5/5. But if u like this app go head with this.
Blackberry Most Business people’s phone, that’s what most of them know about Blackberry. But now the news is Blackberry Looking getting with android and IOS market, that means they wanted to Android and IOS user also should use their messenger. So with BBM we can sync our mail and notification. Still there is no news about Windows phones. Still Having doubt about the BBM how it gonna work, normally without BB Service we can’t access the BBM. If they are promoting the BB service to other Phone OS Platforms also they gonna do something better. In Case they doing like that there is some good free app are there like viber and whats app gonna boost as usual. For Now to Promote and can use with normal GPRS and 3G is better.
Form ICS and higher will support with BBM for Android and IOS 6 and Higher will support with iPhones. If them can capture more place without losing customer better but if they losing more people moving from BB to Android or IOS Devices that’s Bad to Blackberry.
