“The truth is there is no need of firewall for Android device as long as you use reputable Android apps from Google store”
This is nonsense. Google removes hundreds of apps a day from the store. They are removed for reasons that include consumer reports of malware and attacks.
“Nope – no need for a firewall. There are no known viruses for Android, other than the hacked apps from china that were pirate apps to start with.”
This is substantially correct but not 100%. There may be no apps replicating from machine to machine but there is tons of malware that will do tons of nasty things.
It’s worth pointing out that it’s unlikely that your Android phone or tablet has a virus. What you’re more likely to be seeing is an ad that wants to convince you Android is infected and you need to download an app.
