Did you try to reflash your rom without a full wipe?
Or just to wipe cache & dalvik cache & fix permission?

Settings app not opening

I've noticed that in the last couple of days, the Settings app doesn't work properly. At times, when I open the app, it just opens for a second and goes back to the home screen. After some time, the problem goes away on its own. Sometimes, taking out the battery and rebooting the device helps. Sometimes, it doesn't work. Anybody help me out here?

I am not really sure but this might be happening due to a virus or malware. Which RoM are you using?
Sent from my GT-S5830 using xda premium
Stock Gingerbread. 2.3.4!
Try installing any free antivirus and scan your phone. I recommend Netqin

It can also happen if you apply a wrong patch, or flashed something that was not supposed to be flashed on a stock ROM.

No viruses, never flashed or patched anything! :|
maybe because cache is full, can make phone become crazy sometimes.
moreover u said ur on full stock rom without any modification. pure stock rom stores cache in phone memory and it'll be full and cluttered overtime.

Slow operation, keyboard and battery issue

Hi,
I have 3 issues. Hope somebody can help:
1: Phone operates too slow. For example when I go to menu, app icons take around 5 seconds to appear. Similarly when I go to home screen it takes the same lag. So much delay that I could capture the screen short. You can see that weather clock and alarm widgets didn't appear. I cleared cache several times n restarts but it works fine for few mins n then again becomes laggy.
2: Keyboard disappears after typing few letters and sometimes it takes several secs to get it back. Reappearing delay is may be related to the above problem of slow response but why it disappears in first place.
3: Battery doesn't charge despite the whole night charging. Its happens not do often but really bugging me. I noticed that whenever I get missed notifications like calls or msgs it stops charging. Not sure why it's happening.
Looking forward to some help from experts. Please note that I feel these problems are occurring more after recent update. I'm using stock Rom of intl s3 version.
Thanks

Hi,
First, give me your firmware number. Tape *#1234# on your phone dialler. Is it a custom ROM ?

Factory reset it and update to latest firmware via KIES or Odin.
How to factory reset
http://www.jayceooi.com/2012/06/08/how-to-hard-reset-samsung-galaxy-s3/
Thanks.I have the latest stock firmware already. Do you think stock Rom is faulty? And I should root it and lose warranty. I can do that but is it the only solution?

Ok read It agaIn. Thanks. If thats the only solution, will wait for jellybean update that's just around the corner. I wondered if anything related to hardware or phone settings was to be blamed. But anyhow, thanks.
Sent from my GT-I9300 using xda app-developers app
I am also on XXBLFB and facing no such issues. You should check if some app is not eating a lot of RAM.
Jelly Bean won't be available for this region anytime soon keeping in view the time it took S2 to receive ICS update here.
I suspect the same. my RAM doesn't go below 600mb even if I close all apps and clear ram from task manager. After restart, phone behaves well for an hour but then again becomes laggy. My S2 is much faster than this with lot more apps. This S3 is really disappointing me.

Try to find the culprit app. I have 100+ apps and set is still very very smooth.

That's the status when I just cleared cache.
Sent from my GT-I9300 using xda app-developers app
my suggestion is to do a factory reset (after backing up your contacts, messages, notes etc). then download your apps again and note the behavior of phone after each app. You might find the culprit then. It doesn't seem like an issue with the update since I also updated mine. Also very less likely its gonna be hardware issue.
Sent from my GT-I9300 using xda app-developers app
Maybe the CPU is not working at its entire power. If the factory reset is not working, maybe you should go and replace the device, before it's too late. When you bought it ? If the phone have less than 30 days you should get an instant replace. Not sure that JB will help you, as the installation isn't like a "full format" of your phone
Hard reset: *2767*3855# (no warning message before formating, so type it when you're ready, also remove the sdcard if you don't want wiped too.)
Or *#*#7780#*#* - Factory data reset - Clears Google-account data, system and program settings and installed programs. system will not be deleted, and OEM programs, as well as My Documents (pictures, music, videos)
Thanks. Will get in touch with the vendor for replacement (though I'm sure he will not agree that easily) or else will do a complete reset. I'm really pissed off for spending this much for getting this device. Samsung is very serious in pushing their loyalists away!

Sometimes, there can be some errors. You know, nobody's perfect and we are all humans. After one week after I bought my phone, I found that it have sort of scratch on the screen, but looked like inside of it. It could be seen only in high light. The vendor replaced it instantly. This one is perfect. Love it and is extremely fast and I have many apps on it. Good luck!

Check in task manager, you should have an idea about how is going bad. Also change the antivirus for Avast. Avast is much better. However I recommend without antivirus. I just scan sometimes my phone with it or lookout but never leave the antivirus installed. Is just a waste of RAM memory.
If nothing works do a full backup with Kies and do the complete factory reset.
Most of the apps will be automatically reinstalled when you add back your Google account, but you need the backup for settings and saves.

Uninstalled several apps. Removed widgets from desktops. But still same issue. One thing I'm not able to figure out is why my RAM doesn't go below ~600mb despite killing every task n cleaning cache. I guest a factory reset and ROM installation is the only way out. Thanks guys for all the tips.

Even with all the apps I have on my phone the RAM usage is around 580-640 (stupid SwiftKey using 45 mb most of time) and when I kill the apps I have 430 mb, slowly increasing til 530. Try reset, you have nothing to lose.

[Q] Tricks for longer battery life?

Hi All,
Coming from a iPhone4, I noticed that even overnight when the phone is in standby the % drop in the battery is greater on the SGS3.
I am currently running the Omega V25 ROM and the battery drain when in standby is about 10-13% over 7hrs in standby whilst I am sleeping. I read a few days back on the Omega forum (cannot find it again) one of the users saying how great the battery life was for them...something like 1% drop over a few hours in standby....do you know if there is some trick to get such good performance?
I have used good programs like Juice Defender which brings it back to on par with the iPhone4, but does get a bit annoying sometimes waiting for the network connections to restart. Sometimes it even refuses to restart the network which is VERY annoying. I was wondering if there was something I am missing that can get great battery life (IN STANDBY) without 3 party programs like Juice Defender etc....
Thanks,
Ray
Its really all about multiple things
Make sure you got a good kernel. ..I recommend siyah
Imo juice defender hurts more than helps
Check your background apps running and close often
If your going to sleep turn off Mobile data unless you got stuff going on ...dl's dropbox ext...

Go offline on Gtalk, Turn off Wifi/mobile data while not in use. Other thing I do is Download CPUspy on Google Play to verify the Cpu Usage.
With power saving mode enabled I loose only 1-2% of battery juice over night. (Mobile data disabled, gsm only mode).
i9.0.1.3k galaxy imperator
First thing you do is turn off the WIFI or 3G(Mobile data) if you are not using it.

What siyah did you flash? You must flash the kernel for jb leak which is 1.6 and not 1.5.3 because it is for ICS rom. Did you perform wipe cache / wipe dalvik cache?

Hi!
I gotta advise you that juicedefender/other battery defending apps hurt more than it should actually help. Think of it this way, juicedefender is also an app. App=RAM consumption, High RAM consumption=High battery consumption.
Also, flashing a custom kernel can help out. There are tweaks which you can do with custom kernels.
E.G. *Undervolting [if you are a total noob on this, then you might read thoroughly how to do this]
You can have manual settings to low screen brightness, not go to vibrate mode, led notif off, etc. And more importantly, CLOSE APPS THAT RUN IN BACKGROUND Such as: Facebook
You can never really rely that let's say, Person1 is having awesome battery life with KernelX because it depends mainly on your SETTINGS and STANDARD USAGE
I hope this will help you out

Well, I think it happened cause I put 1.5.2 siyah which located at Omega Kitchen...So I need to find siyah 1.6? then go Recovery > wipe cache > wipe dalvik cache? Is that so??

That's the reason why. Yes you can try that. Try to wipe cache and dalvik cache before flashing siyah 1.6. If it does not help then the only option you can make is to full wipe and flash again the rom

Here are some tips:
1. Put wi-fi policy to never. It's in wi-fi settings.
2. Disable unnecessary sync (FB, google, email etc)
3. Install custom kernel, like others said.
4. Install better battery stats and find what's causing your phone awake (wake locks)

Whether Juice defender helps or not depends on your usage scenario and the app configuration (it literally has tons of options)
High ram usage equalling high battery coumption is bollocks. Each and every single operating system out there will try to fill the whole ram because it actually SAVES power and makes the device FASTER.

^^Was gonna post this myself.
Ram uses the same amount of power whether it is full or empty.
Having it filled with apps saves CPU cycles and therefore battery.

Wiping battery stats does "nothing"

Better battery stats for the wakelocks and cpu spy to see if your device is deep sleeping. And if you just flashed something give it a few battery cycles before you judge the battery

Check with other battery, it happen to me and is a hardware problem and not from the ROM or Kernel or calibration... if with another battery is the same, then try to bring it in technical support.
By the way, don't buy a new battery, use a battery from other friend... =)
I have a SD card
hey guys,
I've moved some apps to the external sd card.
After resting my S 2 I've re install the SD but cant move the apps back...
how do I do it?
