If you insist on clinging to your Android, at least be aware of how vulnerable you are.
Security researcher Zimperium, has discovered an attack is possible on ANY Android by creating a short video, hiding the malware inside it and texting to the number of the contact (which you likely know by simply establishing a Whatsapp contact). When it is received by the phone, it will allow the attacker to take over, copy data, delete it, take over the microphone and camera, and does this initial processing before the sound that you have received a message even occurs. it could be absolutely silent, you may not even see anything.
Even though patches are available, and have been sent to Google and acknowledged, the process and speed of getting them to users phones is not in Google’s hands. It is in the hands of the various scattered manufacturers, some of who will not see it as worth the expense to provide an update. It is estimated that fewer than 20 percent will actually get fixed. Optimistically, maybe 50 percent, and Google agrees.
Have fun with all of that Androidians. A much faster solution would be to get a BlackBerry.
