  1. Jayce, what backup method do You recommend?

    I’m switching from S2 to S3 probably soon.

    I could use Kies and Titanium Backup – tho I still haven’t bought the full version – is it worth it?

    The most important things to backup are application settings (not data, I can download the programs/games myself), but I don’t know how I could do that.

    Any help possible?

  2. Hey Jayce,

    I just bought Galaxy S3 from China but problem is all system and samsung apps web site is chinese. How can i format the phone and install new english version of it?

    • Hi Ganaa, I am not sure China SGS3 hardware is the same as international SGS3 or not. SGS2 is not. So can’t use other region English firmware. Try to consult others at XDA website.

  3. hi Jayce, thanks for the advice, i followed the hard set guidance you proposed. it initially worked ok but i never managed to reach to turn on the phone, Samsung Galaxy SIII continues to give the warning “battery temperature low”, any further advice?

        • dear jayce, i left the device plugged with the adapter and left home. After 6 hours, the screen is still the same, level of charging has not progressed ( i know how the screen looks like when it is 100% charged) and i still can not turn it on. what shall i do?

          • meanwhile, during hard reset, i noticed that a blue text appears on the screen saying that “Android OS is updating” with another white announcement below “the process started” but no further action takes place and i see the SGS3 logo once again. Additionally, i can not make this hard reset process if device is not connected to power.

  4. Hi , My palm swipe screen shot has stopped working will have to do a reset to get it going again?

  8. Hi Jayce,

    I am experiencing issues with my SGS3 hanging then randomly turns off. This phone is brand new and I got it from SMART (Philippine Wireless Network Carrier). I already did factory reset and I am still experiencing the same issue. What can I do?

    Please advise. Thanks.

  13. Hello I did a factory reset on my galaxy 3s (canadian Version)
    and when I try to turn on my phone I get a quick recovery booting message in the top left corner and thats it. I am I doing something wrong? please help!

  14. Please I got probs with my galaxy S3 I want some files back in order to been deleted coz my kids been playing with it and I am really affriad if I lost all my stored picS and numbers

  15. Excellent site Jayce!

    Quick question, you mentioned above that doing a factory reset will also wipe the “Internal storage (SD)” – Does this mean the that doing a back up using CWM to “backup to internal sdcard” is pointless when I’m flashing a new rom (as it’s always best to perform the “wipe data/factory reset”).

    Or, is a ‘hard reset’ different to a factory reset? I have a SGS3, but no external SD card, so I was wondering if it’s possible to flash a custom rom, whilst having the option to revert back to the one I’m using now, without having to have done a backup to an external sd.

    Many thanks in advance!

  16. Hi,

  18. Hello, I bought the cellphone on Colombia, but my icons, like camara and others are very ugly and I want to change them, is there a way I get the default icons from the cellphone ? They look kind of cartoony and I think that my provider made them like that.

  19. Hey there…I been looking all over the net for this issue , I got my S3 about 2 weeks back…yes I did Install apps like the regular ones intagram skype n stuff like that..nothing illegal or pirated stuff…now what my issue is my phone works for the most part of the day but sometimes…and i mean only sometimes ..while im chatting or doing something on the phone …Be it any application it hangs and the phone restarts(without actually rebooting…it jus shows a blank screen..the phone vibrates and i see home screen again..) then it works fine…again for the rest of the day but somewhere in the middle this happens…I did try hard reset and Installed everything all over again…but this happened again to me…I would like to know if this is a hardware issue or if there is an app im Installing that is doing it..Cos since its only been 2 weeks…i really im considering replacing this piece…Please help ! thank you.

    • Suspect installed applications are causing the problem. Try to factory reset. Then install application one by one. Find out which application is causing the issue.

      Note – if you face this issue without any application installed (after factory reset), then it is hardware issue.

  20. Thank you for this article. My phone was freezing before I could do a reset from settings and everywhere I looked seemed to take it for granted that if you were there you know how to access recovery on the phone. I have spent entirely too many hours getting my phone operational so I wanted to thank you for putting me out of my misery.

  21. My S3 changes settings by itself. Such as turning on vibrate mode, stopping mobile data, changing email font color and background, and stopping auto rotate. I’m getting tired of having to redo settings several times a day.

  22. hi Jayce,

    My s3 is not working properly using wifi, whenever i turn on the wifi my phone stops working and get stuck on the lock screen, it gets hang and nothing is operational, i have to take off the battery and put that back again, if wifi is off on my phone then there is no problem using the phone, can u plz help me in this stuff???

  32. Ei bro bought samsung galaxy s3 last monday…..had a problem with outgoing sms……says message not sent…..i can still receive sms and calls and also use it to make calls….thanks in advance bro

  33. I have a galaxy s3. Last night the native messaging app crashed and the screen froze so i turned the phone off. Now it will not turn back on. i have tried usb to pc and hard reset but phone is unresponsive.

  34. I have brought a brand new galaxy S3 last week and facing issue when I am calling a contact from my contact list which was imported from my SD card (SD card had the .vcf file exported from my old phone DELL).
    The problem is :

    “whenever i try to call a phone contact or receive an incoming call my screen goes black and phone becomes unresponsive. this way i can neither make calls nor receive any. the phone was working fine until i updated it on 13th july. but the problem started on 14th a day after the update. i get an error msg ‘unfortunately the process has stopped working’

    I found from a forum ( that this occurs because of the contacts that were imported from the SD card.
    I removed all the contacts and now the phone is working but I dont have any contacts in my contact list and to Save all the contacts individually is gonna take lotta time.

    I am not sure what is a permanent solution for this problem and it seems this will happen even if some app (like FB) tries to sync contacts with your phone.

    What will be a permanent solution to this problem and How can I synch my contacts from my SD card (is there any way)?

    Appreciate any help 🙁

  35. i has installed samsungsimpletool for sch-r530u uscc on my pc than i had started following instruction and connected my samsung s3 with pc after 2 hour i have disconnected in between and now my samsung s3 is not working

  36. Hi, my new S3 has gone, stolen. Can’t reach it any more also from Sansung Dive.
    Probably they hard reset it…

    For my next S3 I’ll buy I have a question: is it possible to deny the Hard Reset process?
    Or at least set a password/pin lock to this function?

    I’d like to be sure that noone else will be able to use/reset my phone in the eventuality that I will lose it or (aaggghhh) they will stole again it to me!

    Please, tell me it’s possible! Ah, and how to do it of course!


    • Yes, with password in Android OS. But factory data reset using phone buttons method still can delete everything (the password in Android OS won’t stop him from doing this).

      • Thanks Jayce for your reply 🙂

        Bad thing to know… this way all passwords/tracking software/security options are only nice but useless gadgets…

        Well, I hope at least that IMEI lockout through my phone operator will be usefull to let te phone be useless too 🙂


  37. Hi Jayce ,
    Can you or other people please check this : I updated my SG3 on this version I9300XXDLJ4_I9300OXADLJ4_BTU also on this one I9300XXDLIH_I9300PHEDLI1_PHE and when I try to do a FACTORY FORMAT using dialpad is not working . I open dialpad I type there the code *2767*3855# and nothing happen. I even try to dial and I recieve an error code. What is wrong ? Can somebody else please try these ? and see what’s going on ?I think Jelly bean still have a lot of errors
    Thank you and waiting for a reply.

  38. Hi Jayce, again me
    Please don’t forget about the factory format dialpad that is not working , also I have another problem . CFroot is not working on this update I9300XXDLJ4_I9300OXADLJ4_BTU , please try and see .. is not installing anything , no CW no SuperSu ..

  39. I set a password on my Galaxy S3 SGH-1747M and it worked fine, but then it would not accept the same password. Restarted the phone a couple of times and it would still not accept the password but then it accepted it … wtf, go figure. Could not remove the password because it would not accept the password to make the password change.

    Anyhow, long story short, when I was able to get in I had to use the dialpad reset option to reset the phone because the first two options would not work.

    Jayce, thanks for the info, you saved my ass bud.

  40. hey, jayce i have brought my galaxy s3 from china it have all apps in chinese version so can u tell me how to change it to english version

  41. Hello Jayce,

    I was doing some serach on google and found your information very clear.
    Just a quick question.
    I am thinking of selling my samsung S3 off.
    Don’t want any of my personal data to be on the phone or any of my downloaded application on the phone.
    Pretty much just need to make it like the person is switching the phone for first time. I think it will make it look better as the person feels like he/she is turning it on for the first time.
    My questions will all the pre installed application still there after I do the factory reset? The application that are missing are the ones I have downloaded from the market right? Thanks heaps for your help.

    • As I said, it might be related to your firmware. This might be normal to your firmware. Different firmware has different features. Do consult Samsung Support to confirm. Or your seller.

  46. Hey Jayce, a couple questions. I have paid apps installed on my phone. If I do factory reset, would I lose those paid apps and have to buy them again? Another question, how would you backup the phone? Do you do it from your phone’s backup to Google server option or is there something else like how apple has iTunes. Also after a factory reset, how do I restore my contents back on to the phone??

  47. Hi Jayce, How come its possible to buy a Samsung S3 for around $500 US that is supposed to be original but without a factory warranty.. To get the s3 with factory warranty is $850? Are tehy teh same units?

    Anyone with issues should leave your storey on the BBC Watchdog site as I’ve had the same issues and got nowhere with Samsung.

    RE: Samsung Galaxy S3 I9300 – Bought new in June from the Carphone Warehouse
    I contacted Samsung who said they would send out an envelope to get the phone for testing/repair, but when I sent it all I got was a bill back from them for £119.03 (Parts) + £19.25 (Labour) + VAT@20% = £165.94. When I called Regenersis (Samsung approved repairers) I was told they couldn’t fix my phone under warrenty due to it being rooted, but this phone has NEVER been rooted.
    After speaking again with Samsung they called Regenersis while I was on hold and came back with that phones can be rooted by a random combinations of keys being pressed, but that it was still my fault. When I asked what this random combination of keys was they wouldn’t say. When I said if a kid played a game on my phone (angry birds etc) could they have rooted it, the guy from Samsung basiscally said it was possible!!!

    I have these calls recorded and if anyone wants to contact me from the press, Samsung or a competitor (Apple etc) please do at
