just using kodi, mobdro and a couple of other apps on my ADdroid tv box which I just stopped using cause of all the ADS...
also to answer your question about the apps and the app in question was some fitness abs app I don't recall what the exact name is but it was very intrusive and took over my GF's swipe screen to answer a call!... another note no offence but I hardly believe that you NEVER experienced this in the 3+ years you've been using ADdroid because I have had several friends go through some bad experiences one time or another and myself and my GF with rogue apps taking over their phones or malware and even viruses! also there is a plethora of articles and chat forums describing other horrors that has happened with peoples ADdroid phones and one app that I remember reading about was the messenger app for FB that was a fake one and hijacking peoples FB account and posting adverts and links to video's to all their contacts which happened to my GF and I had to search google to find out what the culprit was... maybe you don't install anything or almost nothing except those BIG apps like FB and twitter and snapchat and major gaming tittles on your phone which is why you've been lucky in the 3+ years you've had your ADdroid phone or something else that's not being said... but for all the MAJORITY of other users do get bad apps/malware and viruses... which is why there is a plethora of anti-viruses apps on ADdroid...
