Apologizes if this is a stupid question, but I'm new and know nothing really about Android. My smartphone of choice for the last 2 years has been the iPhone. But I am now wanting a change, basically getting a little sick of the restrictions Apple impose on their devices etc and like the freedom of customisation of Android. Has you will know Apple has strict vetting for their apps etc and as such the apps are very secure/safe. Just reading through various things on the net about Android/apps. I hear people saying that the app has got hold of sensitive data? such as email addresses, Facebook logins. I also hear some people saying that some Android apps can cause unexplainable high battery usage, whether that is just badly written apps I'm not sure. The above worries/concerns I have raised, I have never had these with the apps for my iPhone. Have I cause to be paranoid, or have I nothing to worry about, what's your opinions?
