Security of smartphones and apps

[wolfeen]

Hello,
I would sometimes like to ask those of you who have a similar smartphone / tablet use and feel comfortable with them with the security there.

I myself have not a smartphone but recently a tablet . Among other things, I am against a smartphone just because of the safety aspect . After all, you always hear that countless apps want to have unlocked vast amounts of data that just too far in the privacy or whatever one may call it, penetrate . Since I 'm much safer with my old Nokia without Internet access.

Now that I have a tablet , logically, with a few games apps , I can see what needs to be because sometimes demands for things. Fortunately, I have , etc. stored on my tablet no contact , which is why it is not there I think so shimmed, as for example like on a smartphone. I think for this reason the whole " app " system for very questionable, as it has the appearance as if one could really do nothing about these apps , unless they just simply do not install . In addition, these brief details " to access .... " not really saying much and can contain quite a lot. The risk that this sensitive information be spied seems to be quite high.
Unfortunately, this system seems to be the future , as much as it bothers me ... So what can you do against such " intelligence " of the apps ?

Because of the apps I do not trust me anyway me to log on my tablet on bitcoiness or similar. I 'm afraid that any app has the right to take notes all ... also is indeed the google authentication on my tablet .. some apps have access to all other apps , so the Garth is still in danger, right?
Oh and where we are already at Garth, white one of you, how the possible hide / password protect can Oder? Don't find it very reassuring that the Google Auth there is simply "freely available" on my tablet and each of the times comes to my tablet could access it.

How far advanced are antivirus systems on smartphones ? And how dangerous apps from sources that are not just from specific stores ? Is this comparable to the security on your PC when you open files from unknown origin , or is it worse / better?

With root access and Xprivacy you can limit what the app is allowed to collect or see from the device.

When using Android devices you should read a manifesto before installing any app.
It is highly not recommended to install .apk from unknown stores / web sites.

I suggest to install AVG Antivirus for Android devices.

I don't trust any devices now. Anything can have backdoors.

This is useful for Android devices.

For iOS, I've heard that there is a built-in support for this; you can control app permissions on app-by-app basis. So if you think 'reading contacts' is not necessary for your news-reader app, you can deny the permission.
