[Galaxy Grand Prime General] kentone:
Hi people!

I recently rooted my grand prime and i want to share the modifications and tweaks that you can apply to your phone.

Mine is the G530FZ, but these can be applied to any grand prime, since this settings are generic even to other phones.

I am very interested in improve the privacy and the functionality of my phone, and some settings don't need root, but im going to share with you anyway since improves your privacy.

HOPE YOU LIKE IT

Enable Dev Options:

Go to About this device, Compilation number and press it repeatedly until it says "Now you are a developer!"

Go back, developer options and tick USB Debugging to enable ADB over USB

-----------------------------------------------------------------------------------------------------------------

I installed Busybox, using Smart Install (Safest), this is important for most of tweaks.

-----------------------------------------------------------------------------------------------------------------

I disabled KNOX, SAMSUNG SUPPORT TOOL and bloats like:

-Play Music

-Play Kiosk

-Play Videos

-Drive

-Samsung Billing

-Play Games

-Galaxy Apps

-Google+

-Samsung Account

-Chrome

And some replaced by:

-Apollo

-FBReader

-MXPlayer

-

-

-

-FDroid (Open Source App Market, your privacy want Open Source!)

-

-

-Firefox

To disable knox and support tool connect your phone through adb or use the terminal emulator and type:

su

pm disable com.sec.knox.seandroid

pm disable com.rsupport.rs.activity.rsupport.aas2

The other apps can be disabled through settings/Application Manager.

------------------------------------------------------------------------------------------------------------------

I installed Xposed Framework, and then this plugins:

-The POWERFUL GravityBox [KK] (Interface and usability tweaks)

-XPrivacy (A privacy manager that lets you choose what information can be read by an application, asking you when the application tries to read something like contacts, use superuser, read messages and so on.)

-XPrivacy in App Info (Injects the XPrivacy settings in app info for the selected app)

-XHalo Floating Windows (Something like a window manager, lets you use apps in the way of windows or anything like that)

-Call Blacklist Pro (The name says all)

-App settings (To fix issues with the dpi change, I will explain it later)

-Xposed Preference Injector (To inject xposed plugins settings on the settings app)

-------------------------------------------------------------------------------------------------------------------

To control what applications connect though WIFI and what though 3G I used AFWall+, and configured it like that:

Mode: Black list (Block Selected) --> This can be done pressing the message that says: Mode: White list (Allow Selected)

On Options/Preferences/UI Preferences I unchecked LAN Control.

Then you can check the apps you want on WIFI, on 3G, on none of that, or unchecked for WIFI and 3G

The first time you need to go to Options/Enable Firewall, and every time you modify the settings press Options/Apply.

Is useful if you have a Bank application and you are afraid about ARP Poisoning on WIFI (Man in the middle) or things like that and you often connect to public WIFI's. You can block WIFI for this app, and let only connect trough 3G.

Or you can block data hungry apps to work only on wifi and mantain your 3G data usage on acceptable limits.

---------------------------------------------------------------------------------------------------------------------

I installed

-Performance Control (The performance app on AOKP I think o.o')

With this app i changed the DPI using the build.prop editor on the last tab, and changed ro.sf.lcd_density to 190

Then you need to use Xposed App Settings plugin to set the DPI's of this apps to 240, because are made to this DPI's and looks ugly, and some even not work:

-Camera

-Contacts

If you have any other app looking ugly after DPI change, use this fix, and tell us here :D

Also the pin numbers on lockscreen will move to the left, but it works, and if you change the DPI's of com.android.systemui the status bar and the notification bar will look fat... (o-__-O)

Don't change cpu settings, i did that and look that does nothing... XD

----------------------------------------------------------------------------------------------------------------------

Also, I am afraid about predictive keyboards and where they send what they predict, so I installed the only Open Source keyboard I found really useful:

-AnySoftKeyboard

It can be installed from FDroid or Google Play, I think that the google play edition updates often :)

Play a little bit with the settings to get your keyboard of choice, it can be tricky at first.

-----------------------------------------------------------------------------------------------------------------------

If you are really conscious about your privacy, you can search for the dev reports that apps send to the developers without your consent and disable it, if you don't care about that, this reports can be useful to some devs :)

And last, and the most conspiranoic app here:

-Android IMSI catcher

This app theorically warns you about IMSI stations near you. This stations are fake GSM antennaes with encryption disabled to hear what you hear and read what you send, explaining it quickly.

I don't know if this app really works, but if it works, and you have spyes around you, tell me if it works ;D

------------------------------------------------------------------------------------------------------------------------

Sorry if i wrote something wrong, I'm don't speak english on my country, I only know the english I learned from series, games and documentation :D

If you need some screenshots for any explained here, tell me ;)

Cheers!
