But if person is using two phones and one have less signal then that person is going to use this type of forum to make the problem known. I can't see any problem with that such as the problem OP is having.

I agree to to use the numbers where available and also ask others to do their research using Google rather then only use this post where some users many not even have or used other phones.

I have agreed with anewhope to make the data available where possible, it's a good point and also shows more facts from others.

Two phones out of twenty million phones are not facts at all .

Neither does it actually answer or give help to the original question .

Does the same test by me with stronger signal on SGS3 not rule out your test ???



The sim free argument is often proven to be false .
The data /network is down to the modem WiFi the kernel .
Sim Free phone may well have exactly the same firmware and modem as a branded version .Many networks do nothing at all but shove the modem out that came with the firmware direct from Samsung .
Signal difference can be significant with as much as a 30% signal on modem xxx and 100% signal on modem yyy . Now that is a network provider problem not an Android/Samsung problem as the networks have not bothered to test .That is one huge advantage Apple have as they tell the networks this modem or stop selling our phones .

I hope you are correct. The last thing customer need is only to buy the phone from the network provider. This will only increase the price and reduce choice.
The post 69 said the battery life increase from 4 hours to normal when updating the firmware from the network.
If this is true then others inc Samsung are giving more power to all network. This cannot be right?

May be network do this for a reason with Android phone so people do not buy sim free or stock version. If this is the case you would be better off buying the phone from network them self at times higher price.

Worth to keep in a mind if someone is looking to buy Android sim free since the sim free phone may not work correctly out of the box or may have network problem. I am sure this type of info will help many others as well as OP.

This type of firmware problem will help networks to make more £ as most will just buy the phone from them or pay more per month. It is in their intrest to make sure sim free phones have a problem.

I have S3 sim free so this might be the reason as well I was not aware of this before.

My phone isn't Android.

The op is asking for S3 not any phone. How can you say it's not correct when you do not know if is true for Android or not? It is based on just what you think.
It seem likely to be correct as others have said that non network firmware can cause problem.

The main phones which can be updated are Android, Win Phone and Blackberry.
The Apple control the update as well as Win Phone.

This might be the reason why network like to push more Android phones.
I am not sure if BB also control the firmware or not.

The networks must be loving this.

All the phone manufactures are and have always been unable to cure the networks domination in selling phones .Apple where able to build the hype for first IPhone and demand that networks did what Apple said .

Nokia release firmware to the networks who then individually decide to release that firmware or not . Networks also decide what branding etc goes in the firmware and when its released for xx market . Hence multiple complaints that firmware upgrades are poor . Note Nokia point made on purpose before the birth of Android its always been a problem.

OK Samsung release firmware upgrade today version I9300XXALF2 with LF2 modem .
That is stock Samsung firmware released to the sim free update servers .
Passed to the networks who look at the firmware and decide if they want to use it or not . If so they then shove the branding in the firmware and some of them may change the modem . Then its released to the update servers .
Same firmware as stock sim free bar the branding .

So there you are on big phone network branded phone waiting for them to upgrade . Here am i with the exact same firmware minus the branding flashed to my phone on the day of release .Here is developer Fred grabbing that firmware and customizing it and in a few days it will be on my phone as a slightly tweaked or themed version of the original firmware .By passing the standard network upgrade path and wait is one of the main reasons the development type forums grow .

In a nutshell Sim Free and Non Sim Free have the same firmware though Sim Free is more likely to be a step ahead in the upgrade path .

So what others are saying is not true. The signal problem is nothing to do with the firmware.
Can the network change the firmware or modem in anyway apart fom the branding?
It would help if you know about S3 or Android not just any phone.
It seem either yourself or others are wrong. Both points cannot be tue.

But the problem is sorted from iOS 4 for iPhones that's what you are saying. All iPhones from 3GS can be upgraded to ios 4 as well as ios 5 so iPhone uses would not have that problem as long as upgrade to ios 4 above is done. I can see your point and I am sure this will help others who are using iOS 3 or below. Good point made

The software update from Apple to adjust how signal strength is indicated in the phone did in not resolve the fundamental design flaw with the iPhone 4, however other iPhones benefit from it because it would now appear to have a connection to the network in dead-zones which it previously would not.

I wouldn't necessarily call that sorting the problem out, although I understand Apple redesigned the 4S to overcome this problem without giving everyone a bumper to surround their phone.

Back once again to the main point:

What are the signal strength and quality values in the stated situation where the S3 is not connected to the network.

A handset saying it is on your network is no use if the signal is that weak you are unable to use the device for voice or data.

One handset saying it has a connection to a network does not automatically mean the other one has some kind of fault; that is a claim without substance.

What data have you used to back up your point or is it something you think?
Now are you saying apart from iPhone 4 all others do not hav a signal problem?
The op was able to send the text with 4S and not with s3.
I agree this do not mean the phone is faulty, may be S3 have a weak signal to save battery. This is what op is asking.
Is it a fault or weak signal by default.

Or it might be 3rd factor to do with the stock firmware. A few here have said that sim free firmware can give problems such as low battery life and signal problem.

It seem know one here knows the answer to help op as it can be any one of the three things. The response such as I don't have the problem is not going to help anyone.

Basic answer is yes they can certainly keep an old modem on newer firmware .Also they can load apps .
Signal on Galaxy range is mainly the modem . That is part of the full firmware package that would normally be updated .

Modems are broadly speaking interchangeable worldwide .
That is modem from Vodafone will work on O2 network etc.

Sample
BULF1 modem goes in branded /provider phones
Omnitel Italy
SFR France
Si Mobile Slovenia
Vodaphone Czech Germany Greece Ireland Netherlands Portugal
Romania Spain UK
And i use it on Giffgaff O2 UK ..or Virgin /TMobile .

3 UK did super tune a modem for the S2 that was reckoned to be superior for all networks in the UK at the time .
Reading 100% and 85 dbm


Certainly no such thing as Sim Free has worse firmware than Sim Locked .
Would i try to cure poor network connection by putting a modem on the phone that is used by the network you are using . Yes it makes sense as a starting point but is no guaranteed fix .

Without going over the top you have answered the question.
Yes the firmware / modem can cause problem with the signal or battery drain.
Otherwise why would you do that if you are sure this will never cause the problem. It is likely this will fix the problem, not guaranteed fix.

It is likely in op's case it is one of the three fault with the phone, weak signal by default or sim free firmware is causing the problem.
