If you have read the news recently, you must know why I am asking this question. Do you use the green app to chat with friends? Well you must be embarassed now since you know the level of risk you are facing now just because you have the green app installed.
Whether or not some third party has had access to it, your phone is now in an untrusted or compromised state.
Would you need to take a good decision in this case? Well, it's up to you. This is your life after all!
Anyway please take a second to let us know in the comments section what do you think someone should do if he/she uses the green app.
