Hi Friends, 

       I read and saw some news about the privacy issues with facebook and its application on android phone like :

http://www.onthemedia.org/story/why-facebook-wants-access-your-phones-microphone-all-times/

http://mashable.com/2014/08/11/stop-freaking-out-about-facebook-messenger-app-permissions/

and other articles and videos.

So gave my self a thought that why the hell do Facebook need permission which are not related to the operation of the application like reading/sending my sms/contact/calls, storage, recording features and much more.

On the other hand I want to use Facebook and its messenger. Now how to get around this problem so I searched a bit and got a workaround.

In short (for geek/nerd kind of guys) what I did (Galaxy S3) is :

• Root your device
• http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
• Install Xposed framework
• http://repo.xposed.info/
• Install AppSetting framework from xposed repository 
• http://repo.xposed.info/module/de.robv.android.xposed.mods.appsettings
• Using Appsetting go in facebook and revoke the permissions you don't want any application to have, like removing camera,sms access from Facebook applications.
• Thats it .. Use application and be secure :) 

Updated: I put a comparison of permission on android apps (Facebook, Facebook messenger, Skype, Viber) that I use normally. and also I used above procedure to remove some permissions. details are here:

Detailed information about the process from start:

• Root your device
• To Root I used this simple tutorial (Samsung Galaxy S3).
• http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
• Install Xposed framework
• http://repo.xposed.info/module/de.robv.android.xposed.installer
• First you need to install framework, copy apk in your device and then use it. Make sure your unknown sources is checked in setting. If you dont know unknown sources setting, this might help

• After installation it might ask you to grant supersu permission to XposedFramework, grant it
• Install AppSetting framework from xposed repository 
• http://repo.xposed.info/module/de.robv.android.xposed.mods.appsettings
• Copy apk to your device and install.
• After installation it might ask you to grant supersu permission to AppSetting, grant it
• After installing app setting you have to enable 

Select Xposed Installer

Selects Modules

Enable App Settings and Reboot

• Using Appsetting go in facebook or any other and revoke the permissions you don't want any application to have, like removing camera,sms access from Facebook or any other applications.

Open AppSetting

Select Facebook or any app to revoke permissions

1. switch on settings

2. select permissions

1. switch on permissions

2. touch permission you want to remove and press OK

after Ok you will be redirected to above screen press save button and click ok, relaunch application and you are good to go.

• Thats it .. Use application and be secure :) 
• Using above process you can check application that are accessing more than they require for their operation.
• if after revoking permissions your application crashes try revoking 1 permission at a time and relaunching application.

Good Luck Guyz.
