Every couple of days, when my phone has plenty of enough charge my phone decides to reboot, sometimes whilst I'm texting, on the internet and playing games other times it will be in my pocket or on my desk next to me. I would like to know what's up with my phone and why does it do this. Does it need a looking at?

My Galaxy S2 has been rebooting/restarting randomly every few days since I updated the firmware to 2.3.5. On top of that it started freezing and sometimes even fail to connect to the vodafone network and I had to restart it to get it to connect.
I tried factory reset but that didn't solve the problem.

So we can look at this in more detail for you the first thing that you will need to do is to send the phone away for a free of charge warranty repair.
If this then continues after the repair please let us know and we will follow this up for you.

I am having the same problem as other posters here so it sounds like I need to send my phone for a repair also.
Unfortunately the link posted above doesn't work, can someone provide an alternative?

I thought after getting my 5 day old phone swapped for a new one the reboot issue was over and done with, 5 days since it was replaced its just done a random reboot again..
anyone else have this issue with the S2 ?
its only been up for an hour as i restarted it
i hope its just 2.3.5 bugs that ICS 4 will sort out...

i think its 2.3.5 to blame as those on ICS dont have this any more.

I have the same problem, went to vodafone store & I was advised to update the software. I have no idea how to find out what version i'm on, or even what software i'm currently on, & how do i update it? I was also advised to install kies to back everything up, but i heard when i bought the phone, that kies is a bad idea. I don't know how to install/use kies either. Does it back up everything - messages particularly, downloads, contacts? Any help out there gratefully accepted.
Wow what a lot of questions
on your phone
Press menu > settings > about phone
Then tell us what the baseband Version is ?
we will tell you then what is on your phone
Now Kies is not as bad as it used to be
with kies you can back up contacts music pictures but not messages
Now i use Kies and back up to Microsoft outlook works every time, now your messages can be backed up to gmail using a app from the market just search for sms to gmail this will back up your messages to gmail and you can view them via a computer online.
Now apps are allready backed up on the Market, Other downloads are stored on you internal or external sd
These can be backed up setting your phone to mass storage mode it's then like a usb stick.
Kies can be down loaded from
down load it and install it, make sure your phone is not in mass storage
open kies up then plug in your phone
Your pc will do a phew things, this is to install the phone, now top left of kies it will say connecting, it might not connect first time
Now windows will open a box this is the auto play menu just minimize it.
If kies still has not connected un plug wait ten secounds then re connect
with in kies you can then go to the back up section there is a good help guide on there if you get stuck

The thing to realise with these reboots is that they're a crash in the phone's operating system. The same way windows occasionally blue screens and reboots your PC.
There's one of two causes for this. Either the Operating system itself is buggy and causing the crash, or an application (via a request to the operating system) causes a crash.
Error messages, warnings and diagnostics from applications are all stored in a logfile on your phone, and if you're a) lucky enough that the crashing feature writes the error to the log and b) technically adept, you can read this log and get some idea of what was going on.
A question for those who have had the crashes occuring.
What MicroSD card do you have installed in the phone?
Is it a new one? Or an old one from a previous phone?
Do you know what class of MicroSD card it is?
I had problems with my old Sony Ericsson Xperia (What a hunk of junk that was) because the MicroSD card in it was too slow (low class card). I switched card to a newer/faster one and the problems went away. I don't know if this is an issue for the S2, but if you are going to install apps on the SD then ensure you have a decent SD card in the phone.

now the problem here is pinning in down to what app is doing this
if you gave us a list of apps, not games as they don't use the phone in the same way seems very strange your on two that have this

DJ - you're wrong there, technically
Applications cannot directly crash the phone as all the hardware resources are managed by the kernel. They make requests to access them via the kernel. What's probably happening behind the scenes is that one of these requests is bad and has caused the kernel to crash.
It's the kernel's fault that the phone has crashed becuase it's supposed to be fault tollerant and deal with bad cases without bringing down the phone. It could be a hardware fault but to have a second phone thats faulty would be incredibly rare.
So yes, it's likely the apps fault for doing something stupid. Or it could just be a bug in the kernel. Or it could be a resource conflict.
I won't go on as the details don't matter. What matters is that the guy has a problem.
Like NDJ says, provide a list of the apps you installed. We may be able to identify the ones that are likely to run in the background. You can then start taking these off the phone in an effort to identify which one is buggy.
