Towelroot app makes it easy to root Galaxy S5 & other locked Androids

To root or not to root, that is the question ...

Several years ago, I had the first Android phone released, the HTC G1, which I rooted within days of purchase. At that time, it seemed the best course, as the stock G1 had a number of unnecessary restrictions, including no pinch to zoom & no WiFi hotspot.

Now I have a Samsung Galaxy S4, unrooted. Why no root? For me, the benefits are no longer there. Among other things, pinch to zoom & WiFi hotspot are both standard.

Some of the restrictions in stock devices are security measures. However, this can be fall down if a vendor is slow in releasing a security update.

Towelroot is a special case with respect to security, because it makes use of a vulnerability in many Android devices. The same vulnerability may be exploited by a piece of malware. Paradoxically, the best way to protect yourself against this exploit right now, is to exploit it yourself by rooting using Towelroot.
