According to Viber, the company quickly released an update to fix lock screen errors on Android phones.

As reported, not long ago the network security company BKAV provided a number of videos showing the vulnerability of the Viber application on Android smartphones, making it easy for hackers to break into these phones.

Viber has successfully overcome the lock screen error on Android Picture 1

However, Viber soon provided updates on Google Play to fix the error.

Viber is currently the number 1 free messaging and calling application in Vietnam (ranked by number of users) with about 3.5 million registered users (data published in March 2013).

Currently in Vietnam market, in addition to being stormed in other segments, Viber is said to occupy a unique position in middle-aged and near-middle-class customers. In order to beat the competitors in the above segment, it is probably thanks to Viber owning the interface is quite simple and easy to manipulate. Besides, Viber is also quite "awake " when launching some stickers to compete with competitors who are famous for funny icons like Line, WeChat, .

On the other hand, some comments on the technology community suggest that Viber is in a position to be given free ' word of mouth' advertising among users. Since this application is having a huge user set in Vietnam, and these users whisper, invite each other to use the application to be texted, make free calls.

Therefore, in the war of media promotion for the hot free calling texting application in Vietnam, Viber fought quite a bit and perhaps the resources that this company spent is not worth it with another opponent.
