Can Android phones be hacked?

Android phones are more prone to hacking and as per Malwarebytes report, there has been a rise in pre-installed malware and adware on the devices of Android users, with the goal to either steal data or steal attention. To keep your privacy protected you must always keep a check on your phone’s behaviour.

Is your advise on removing spywares or unknown apps still applies to this since Android is prone to hacking?

It still applies. It doesn’t mean when it is prone to hacking, it can be hacked or is hacked.
