2Samsung Galaxy S3Samsung Galaxy S3 & Note 2: Mods, tips & tweaks

I’ve had my Galaxy S3 a little over a month already and have slowly been com­pil­ing a worth­while list of tips and tweaks that I use and can recom­mend to other users.  I’ve updated the list to include tips for the Galaxy Note 2 which my part­ner now has.  Many of these may also apply to other Sam­sung or even other android phones, but some are spe­cific to the galaxy S3 or Galaxy Note 2.  By all means try them regard­less of phone and let us know how you get on.

Major update (18th-Oct-2012): Now includes tips for both Galaxy S3 and Galaxy Note 2.  Tips are for both phones unless noted.

1. Root it

Des­pite what you may have heard else­where root­ing now is a very quick and pain­less pro­ced­ure.  Tech­nic­ally it does viol­ate your war­ranty, how­ever, if you need to use the war­ranty simply unroot again before return­ing the phone.  Unroot­ing is just as easy as root­ing.  I’ve already writ­ten up the root­ing pro­ced­ure for the Galaxy S3 and the Note 2 so rather than repeat it here just read my ori­ginal articles.

2. Install AdFree

I’m will­ing to bet a good num­ber of you already use Adb­lock Plus in Fire­fox or Chrome on your PC.  Why suf­fer the ads on your phone — espe­cially as they can ham­mer bat­tery life?  AdFree is an app avail­able on Google Play which blocks ads on your phone.  It mod­i­fies the hosts file so it blocks ads in all apps not just when you’re web brows­ing.  You do need to be rooted though, so count this as the first good reason to do the root men­tioned in step 1.  As of 11-Apr-2013 Google have removed all AdB­lock­ing apps from the Play Store.  You can get AdFree dir­ectly from BigTinCan.com.  For more inform­a­tion, see our art­icle Google removes ad block­ing apps: Get them here

3. Upgrade the cam­era app

Update: I no longer use this mod as the built-in cam­era app has improved in Android 4.1.2 and this mod is buggy and no longer being act­ively developed.  How­ever, you can still go ahead if you wish…

This is prob­ably the best known mod for the Galaxy S3 & Note 2.  XDA-Developers mem­ber hyperX has mod­i­fied the built-in cam­era app and enhanced it in sev­eral ways.  The mod is avail­able either as an .apk which you can copy over the ori­ginal, or it comes as a flash­able zip.  Flash­ing the zip is done via recov­ery (e.g. clock­work­mod) which you get when you root.  Altern­at­ively you can over-write the .apk with a file man­ager app (e.g. ES File Explorer, avail­able free from Google Play) but again, you need to be rooted, so count this as your second good reason to do the root men­tioned in step 1.

4. Enable swype-style key­board input

With the new­est Galaxy phones Sam­sung have included Swype-like func­tion­al­ity.  I find this use­ful when try­ing to type when I’m a pas­sen­ger in a car as keep­ing my fin­ger on the screen is easier than being accur­ate if the road isn’t silky smooth.  Go to the home-screen, press the menu but­ton and select set­tings.  Choose “lan­guage and key­board” and then “key­boards and input meth­ods”.  Press on the gear-wheel next to the “Sam­sung key­board” option.  Make sure “pre­dict­ive text” is set on and then turn on “con­tinu­ous input” (not to be con­fused with key­board swipe!)

5. Set up facial recog­ni­tion unlocking

Unless you need a stu­pidly secure phone hav­ing voice or facial unlock­ing is actu­ally pretty handy, I use facial recog­ni­tion unlock all the time, its much han­dier than hav­ing the swipe a pat­tern or enter a pin.  Go to the home-screen, press the menu but­ton and select set­tings.  Choose secur­ity, screen lock and then face unlock. Fol­low the instruc­tions to set it up.  There are other options you can also set up — choose whatever suits you.

6. Turn on “smart stay” to pre­vent screen timeout when in use

On of the well pub­li­cised fea­tures isn’t actu­ally enabled by default.  I can’t under­stand why as its one of the most use­ful fea­tures I’ve found on the S3 com­pared to my old HTC Desire.  Smart Stay uses the front-facing cam­era to pre­vent the screen timeout turn­ing the screen off if it detects that you are look­ing at the screen.  To turn it on go to the home-screen, press the menu but­ton and choose set­tings.  Open the dis­play set­tings and turn on “smart stay”.  Simple as that.

Prey_QR7. Install prey

Premium smart­phones are always a rich tar­get for thieves, but thanks to their GPS and data con­nec­tions it is pos­sible to turn the tables on would-be scum.  The free ser­vice prey provides a small app which you install and asso­ci­ate with your account.  You can then remotely loc­ate, con­trol or lock your device.  You can also make the device make a loud noise to help you find it if you’ve lost it some­where in the house.

8. Con­sider some of the apps on my recom­men­ded list

Every 6–9 months I pub­lish a list of the apps that I’ve been using reg­u­larly.  They’re almost all free, and I’ve lis­ted them entirely because I use them — there’s noth­ing sponsored there.  Take a look at the most recent apps-list and see if any­thing takes your fancy.

9. Auto-haptic set­tings (Added 10-Aug-12)

The Galaxy phones include an “auto haptic” fea­ture which turns all out­put­ted sounds into auto haptic feed­back.  This is really use­ful for some apps, but a waste of power for oth­ers.  For­tu­nately it can be cus­tom­ised by app.  To turn it on go to Set­tings, Sound and scroll to the bot­tom and click the slider to turn auto-haptic on.  Then Press and hold on the “auto-haptic” name to open a list of apps.  Untick indi­vidual apps for which you don’t want auto-haptic, e.g. nav­ig­a­tion apps and media players.

10. Access ser­vice menus (Added 16-Oct-12)

There are vari­ous codes you can enter into the dialer to gain access to sev­eral ser­vice menus.  There are also some codes float­ing around on the inter­net that will fact­ory reset your phone.  Don’t dial ran­dom codes in without check­ing them first!

  • *#0*# — this gets you the LCD test screen which has lots of options
  • *#1234# — this tells you sft­ware ver­sion information
  • *#12580*369# — this gets the same as above plus some addi­tional inform­a­tion includ­ing the hard­ware revision
  • *#0228# — this gets bat­tery status information

11. Using the motion sensor (Added 16-Oct-12)

Turn on the motion sensor and its vari­ous sub-options to enable lots of ways of con­trolling the phone through tilt­ing twist­ing and shak­ing, including:

  • swipe palm across right to left to take a screen­shot (or just hold the menu and power but­tons at the same time)
  • shake to bring up the dialer
  • turn over to mute a call
  • double tap top to return to top in lots of apps with scrolling
  • double hold on images to zoom and single hold and move phone to move around image

12. Improve char­ging speed (Added 16-Oct-12)

Sam­sung phones, Like HTC’s (and prob­ably oth­ers) only charge at full speed from the sup­plied wall-wart.  In the wall-wart the USB data pins (2 and 3) are shor­ted together to tell the phone to draw a higher cur­rent from the char­ger.  Whilst it is not easy (or advis­able) to try to achieve this with a PC, it is pos­sible to do so with cheap 3rd party char­gers and in-car char­gers.  Simply open the device up and short the middle 2 pins.  For more detailed inform­a­tion see my pre­vi­ous art­icle about how to do this for HTC phones — the pro­ced­ure will be identical.

13. Dis­able the annoy­ing “tab” at the bot­tom for “multi win­dow mode” (Added 12-Jan-13)

You can tem­por­ar­ily turn off multi win­dow by hold­ing the back but­ton down for ~2 seconds.  How­ever, hold­ing back a second time brings multi win­dow back.  To turn this off per­man­ently go to set­tings, dis­play and untick “Multi window”

14. Resolv­ing the lack of auto­cor­rect / auto­sub­sti­tute in Jelly­bean and newer (Added 25-Feb-13)

Update: See tip 16 below for the altern­at­ive key­board we recommend

Sam­sung, in their infin­ite wis­dom, have decided to remove one of the most fun­da­mental fea­tures of the key­board in the update to Android 4.1 (Jelly­Bean): the auto­matic selec­tion of the most likely word!  Sadly they have actu­ally removed this, there is no way to turn it back on in set­tings.  So, stop wast­ing time try­ing to get it back (or won­der­ing if you just ima­gined that it once worked) and get an altern­at­ive key­board from the Play Store.  Please post your altern­at­ive key­board recom­mend­a­tions in the com­ments below.  Thanks.

15. Turn on “Google Now” (Added 30-Mar-13)

There are sev­eral ways to turn on and access google now.  The easi­est is to press and hold the menu but­ton — google now should just open.  You can also access it by hold­ing down the home but­ton for 2–3 seconds, and when the screen changes click on the ‘g’ but­ton at the bot­tom centre.

16. Replace the key­board with the Google Key­board (Added 7-June-13)

With a pre­vi­ous update (I’m not sure exactly which), Sam­sung changed the key­board func­tion­al­ity slightly, and word pre­dic­tion no longer chooses the most likely word — mean­ing texts take longer to write, or con­tain lots more errors.  Google have now released their default key­board on the Play Store so you can down­load and use it instead (for free).  All the feed­back I have seen so far has been pos­it­ive so give it a try and see if you prefer it.

17. Stop Face­book chat track­ing you (Added 7-June-13)

Assum­ign you use Face­book on your phone (and I guest a sig­ni­fic­ant major­ity do) you may (or may not) have noticed that if you send a mes­sage to someone it will include your loc­a­tion.  To dis­able this you need to install the “Face­book Mes­sen­ger” applic­a­tion from the Play Store.  Once installed, open mes­sen­ger, click on the menu but­ton, and select set­tings.  Click on “Loc­a­tion” and untick “Loc­a­tion is on”.  Then select OK and use the back but­ton to exit the app.

18. Get Face­book mes­sages on your home screen (Added 7-June-13)

Face­book have released “Face­book Home” func­tion­al­ity for smart­phones which allows face­book to inter­act with your homescreen and appear over the top of other applic­a­tions.  To allow mes­sages to show up (or to hide them) without installing the entire Face­book Home app you can use the Face­book Mes­sen­ger app.  Install it from the play store, open it, press the menu but­ton and select “set­tings”.  Select “Noti­fic­a­tions” and then enable (or dis­able) “Chat Heads”.  You then need to get someone to send you a mes­sage — it should pop up no mat­ter what you have open on your phone.  From then on you can open any mes­sage, old or new, and it will pop up a round float­ing “head” to track the conversation.

19. Increase bat­tery life with a big­ger bat­tery (Added 7-June-13)

Higher capa­city com­pat­ible bat­ter­ies are now avail­able.  The S3 has a 7.98Wh 3.8V bat­tery as stand­ard.  This trans­lates (from P=IV) into 2079mAh, or 2100mAh as mar­keted.  “Gold” grade sub­sti­tutes are avail­able up to 3250mAh as a stand­ard fit, and up to 5500mAh with a fat­ter­back piece.  This equates to 55% greater for a stand­ard fit, and 260% greater with a lar­ger lar­ger replace­ment back.  Using non-genuine parts will of course inval­id­ate your warranty.

That’s all for now, but I’m sure there will be addi­tional tips com­ing in the future.

    Key­board sug­ges­tions: Swype, of course, is a clas­sic. Swiftkey is very good if you don’t mind a breach of pri­vacy in the name of con­veni­ence. I am cur­rently using GO Key­board. It was advert­ised to be very cus­tom­iz­able. Unfor­tu­nately, they just mean col­ors and such, not much in the way of lay­out. But I like that it brings back auto-correct and a more google-keyboard-like emoticon sec­tion. I still miss the row of num­ber keys along the top of the alpha key­board, but it has a very nice 10-key num­ber pad you can bring up at any time. Only com­plaint is that it has 1 at the top left instead of bot­tom left.
