No with that little information only you can help yourself by getting more into android for s2. Are you still on stock or do you have your device rooted (for a start)?

Go to Settings -> WiFi -> Advanced (from options menu) , and make sure you have "Always" selected under "Keep Wi-Fi on during sleep"

What ROM / kernel version do you have?
Check Settings > Display > Lock Screen, Display Timeout, and Settings > Security > Screen lock, Auto lock (or something similar in your ROM version).
And you will have to unplug your phone from charger.
Charging will prevent the phone from going into deep sleep.
If the screen lock does not work, you may have to flash the ROM again to your phone.

How stable is the firmware 4.0.4 for I9100G

Hi
I have a 4.0.3 france firmware installed samsung I9100G.But lately the no lockscreen problem (holding the power button will not bring the options and just shuts the phone off),ringtone and a few other problems started to annoy me really bad.
I'm thinking to install the 4.0.4 german firmware from samfirmware but how stable is it? is there any problem with the 4.0.4 or anything special i should know about it?
i have reflashed the 4.0.3 but those problems didnt go away.
thanks for any helps.
Go back to GB.For me that is more stable than ICS or JB.

If the firmware is official, it should be stable. So, your choice: or GB, or ICS.

updated to 4.0.4 but nothing changed.
ok here are the problems:
- The power button options are not showing up. if i hold the power button it just closes the phone directly.
- The screen lock doesnt work. Wont lock the screen with any option there.
- The sim lock doesnt work. If i put the sim lock on (put a lock on the sim) the phone starts normally but wont let me call or text. So i have to disable the lock on the sim to make it work normal.
Now these are the problems i have seen so far. When i got the phone it was GB and there was absolutely no prob until updating to ICS. So whats the suggestion, should i give a try on custom firmware ICS or go back to official GB? if you say custom firmware then which one?

It's always recommended to perform a factory reset after upgrading your phone software

For me the samsung stock roms are like windows o/s.
GB=xp
Ics=vista
Jb=w7
A crude comparison......but vista was a pile of crap.....

1. If your phone is not rooted, root.
2. Create file /efs/imei/keystr, containing the word ON.
3. Make sure the file has rw-r--r--, or 644 permissions.
4. ...
5. Profit!

ok thank you very much bro. that did it
i first rooted the phone from here: http://forum.xda-developers.com/showthread.php?t=1679778 with the option 2.
then used this little guide:
- Download "Terminal Emulator" app from market
- open it
- type into the command:
su
echo -n ON > /efs/imei/keystr
sync
Go to home, force close your terminal app, shut your screen off, and when your turn it back on your lock screen should? be there.
Obviously you must be rooted the "su" command
And for Signal Problem Simply do not put any pin on your sim ,,,

Firstly take a backup of all your messages,contacts and apps and do a factory reset.
If the problem Persists Do a system wipe by Entering the recovery And then flash the stock rom.
Take a backup of your rom before you do so.

Did you turn on your Wi-fi (sounds stupid, but sometimes happens)
Have you tried these things below:
Restart your router
Restart your phone
That's the only things I can think of to fix your problem
Scanned,with catlog and found some errors,anyone can tell what is about?
And also who can help me with a backup of folder wifi from data/misc/wifi on 4.1.2 stock rom?
