Question

How secure are mobile apps that require access to your phone's features ?

Answer 1

it is correct when you installing an application you will accept different type permissions. that will be more or less based on that application. It's easy to get frightened when you see the app need too much permissions from trustworthy sources. when you think to install an application just go yourself through these questions,

• Is this app from a trustworthy developer or not?
• Does it look like malware?
• Do I understand why this app needs these permissions?
• Does the developer explain to me why they need these permissions? (Are they listed at Google Play, along with the reasons for each permission request?)

if your answer for all of these questions are 'yes', you're in good shape. If your answering 'no', you just rethink that application you really need the app. Even apps from trustworthy developers can collect a great deal of data, either for advertising and marketing purposes, or because someone screwed up. If you have an app from a developer you've never heard of and it doesn't explain why it needs the permissions it does, stay away unless you understand that the permissions are necessary for the type of app it is.
