Top reasons to root Samsung Galaxy S2

Why you should root Samsung Galaxy S II? Before using Samsung Galaxy S2, I am an Android HTC HD2 user. And all the custom ROMs for HTC HD2 are rooted by default. Therefore, I don’t have any issue to use Android applications that require root access. Here are my top reasons why you should to root Samsung Galaxy S2.


Root Android

Backup & restore application and data
Titanium Backup is the must installed Android application for rooted Android phone. It helps to backup your Android applications and data. Restore them when needed. You can even schedule the backup. You don’t want to loss any important data, right?

No more advertisements
Addicted to ad-supported free games like Angry Birds? You can turn it into a full version game without advertisement with AdFree Android. AdFree removes most ads in the browser and other applications by nullifying requests to known host names in the system hosts file. Yeah… No more advertisements.

Improve user experience with custom modification
Ability to use improved modified built in Android application. For example, a mod SGS2 camera that enable feature like hold volume key to focus and release to shoot. You need root access to replace the existing camera application. Or disable full battery charged notification by changing the system configuration.

Remove unneeded bloatware system applications
Certain bloatware system applications / services eat your phone CPU, memory, data and battery. You can improve your phone performance by disabling them. App Quarantine (ROOT) is the application that you can help you to do so.

Better and faster custom firmware
You don’t get it with rooting but with CF-Root that you installed bring along ClockworkMod recovery (CWM). CWM allows you to install better and faster custom firmware. No need to wait for official firmware release and try out the latest and greatest custom firmware out there.

Speed up CPU and improve battery life
SetCPU for Root Users is a tool for changing the CPU settings. You can use it to improve performance or save battery. Overclock Samsung Galaxy S2 from 1.2 GHz to 1.6 GHz to improve overall performance. Or undervolting to save even more battery.

Faster GPS signal lock
FasterFix enhances your GPS by using a more accurate time estimation from a NTP server near you. Personally, I select Malaysia NTP server as default. A great tool that can speed up GPS signal lock when you travel to other country.

Play Tegra, Snapdragon & PowerVR Games
Enjoy Tegra, Snapdragon & PowerVR games with help from Chainfire3D plugins. A must installed application for Samsung Galaxy S2.

Enable MSAA on OpenGL 3D Games
Hardcore gamers, Chainfire3D Pro is the must installed Android application on your SGS2. It will help to enable Multi-Sampling Anti-Aliasing feature on 3D OpenGL games.

Improve Super AMOLED Plus Display
Voodoo ScreenTune will make your Samsung Galaxy S2 Super AMOLED Plus Display looks better and lesser colour banding issue.

Unlock Samsung Galaxy S II
Free your Samsung Galaxy S2 with Galaxy S2 SIM Unlock App for those locked SGS2. Don’t bond yourself with only 1 telco SIM card.

Block Internet access with firewall
Restrict certain Android application from accessing Internet. Improve battery life too with lesser Android application accessing data connection. DroidWall is the Android firewall application that you need.

Access to other region Android Market
Google Maps is not available at Android Market in Malaysia. I cannot access to Android applications which assign to non-Malaysia country only. Market Enabler helps to solve this issue.

Screen standby on MHL / HDMI mirroring
Screen Standby switches off the screen temporarily without actually putting the phone into sleep mode. Great for saving your battery and avoids heating to prolong battery life while enjoy games and movie though MHL / HDMI mirroring on TV.

    Dear Jayce,

    Rooting the phone seems so important for every new phone, Btw, Is it means we still can maintain our main memory details after rooted? And, will the phone damage after rooted? thanks in advance..

    • http://www.jayceooi.com Jayce

      Main memory details?? What do you mean?
      The phone won’t have issue after it is rooted properly. Lot of Android phones out there are rooted. Personally, I am using rooted Android phone for years. No issue at all. ;)

        • http://www.jayceooi.com Jayce

          No, rooting won’t delete your data. It just modify your phone kernel.

        • http://www.jayceooi.com Jayce

          Samsung Kies is known to have issue on backup / restore. So better backup file, photos, videos, data to PC manually. Contacts to Google Account.

    Dear jayce,
    Writing from belgium. And i have an sgs2.
    PDA I9100XWKI9
    PHONE I9100 XXKI4
    CSC I9100PROKH1.

    I still have a sgs2 rooted device. I am waiting already a longtime to unroot it, because I thought, once unrooted I would be able to get via Kies the official update. Is that correct ?

    The official update is not arrived yet because there were problems with the bleutooth (in cars?).

    I found your website very interesting and find a lot of things.

    I would really to consider to root if I could still update to ICS. Is that possible ? And how.

    If unrooted, and i do not wait for the official ICS, what is the rom that you would advice me (no problems/restrictions for bleutooth or other soft or hardware. I know you wrote a lot of things, but now you must have another up-to-date opinion.

    I am quit new in rooting (but i succeeded once with my first Galaxy TAb.

    Kind regards

    And thanks in advance. for helping me out !

    • http://www.jayceooi.com Jayce

      No, root access does not affect the ability to upgrade with Samsung Kies.

      Yes, you can update to ICS firmware after rooted. Install through Kies or Odin manually.

      No idea which ICS ROM is the best one as I am still testing them.

      • steven

        Hi Jayce,

        Thanks for the RAPID reply. Thanks. I am going to root it, this evening. I was also going to install the ICS, but now i am hesitating.

        I was thinking of the european official version of ICS or the 4.04. I will see. Keep you informed.

        What is the best way to back up ? Titanium ? what is advised.

        • http://www.jayceooi.com Jayce

          Titanium Backup.

      Hi Andre, what is your issue?

  • Tony

    stumbled across this post about rooting. Now i can honestly say for me anyway there is reason to root. So i guess I will have to do a lot of research to get an understanding before I root my GS2 on ICS 4.0.3. mainly because of battery life and removing unwanted system apps thanks!
