[Q] Cell Stand by fix. - Galaxy S III Q&A, (US Carriers)

Has anyone done the cell stand by fix on the U.S version? My cell stand by is anywhere between 40 and 50 which can not be normal. It uses more than my screen and I run it full on bright. Thanks

XDA GSM Signal Reaquisition.

I posted this message at www.pdaphonehome.com but I thought I might give it a shot here and see if I can get diffrent results.
I'm in Sydney Australia and have recently puchased (brand new.. not off of ebay or anything) the O2 XDA (32/64mb). Rom version is 3.14.17 ENG with a Radio version of 4.16 and have encountered the dreaded SIGNAL LOSS / REAQUISITION problem.
I switched from a Treo 270 (which had the dreaded back light problem) and absolutely LOOOOOOVE the XDA (plus the fact that I can code VB apps for it too is kinda nice without paying for the dev env) aaannnyway....
(is it me or does it seem like most PDA-Phones have at least one Dreaded Problem).
I'm currently with a carrier which has almost no signal at my workplace (vodafone) and am at least 12 months away from my contract ending so swapping carriers to the better Optus or Telstra is a no-no.
I've managed to trawl around and managed to find some information on the Signal loss / reaquisition.
1) The phone takes an awfully long time to reaquire a signal after coming back from an area with almost no signal. I've managed to time it and on average it seems to take about 10-15 minutes to reaquire. It also needs a STRONG signal to reaquire it and will take longer to reaquire if it's a weak signal.
2) Occasionally the phone gets "stuck" and while it reports a full strength signal, no-one can seem to call or send SMSs
I've tried to use "Phone Today" and it does seem to make little or no diffrence in my situation.
From what other sites (as well as this one) have reported, it has something to do with people only in fluctuating areas of signal combined with a long refresh interval on the phone rather than a defective phone. Am I right?
What I'd like to know (throught your wealth of contacts) is the following.
1) Is O2 Aware of this problem? I've seem forum postings where O2 have admitted to it. Can anyone confirm this? I managed to contact O2 Australia and they've denied (surprise surprise) any knowledge of the problem. Mind you I'm not sure how prevalent the XDA is in Aus so the guy on the phone may have been genuinely ignorant of the problem)
2) Can anyone confirm whether O2 is working on a patch or update for this. I know an ETA is too much to expect but some acknowledgement would be nice.
3) I understand that the AT&T SX56 is practically the same machine and it has it's refresh rate set to 90 seconds as opposed to o2 which I'm assuming is every christmas (but only if you feed it cookies). Would fixing the problem be as simple as using the radio rom from an AT&T on a XDA?
4) Is there anyway to hack the radio to up it's refresh rate? (might breach some copyright laws ... apologies if I've stepped on anyone's toes)
5) Is it true that when it tried to reaquire a signal, it goes into a high frequency seach mode (or something like that.. I don't know.. *sigh* ) which chews up more power? Does this mean that if a more frequent refresh rate were to be implemented, the battery life would decrease significantly?
**new addition**
Since I do have a little knowledge about emVB may be a temporary solution might be possible if I could code one.
Is there an API / for the GSM component of the phone. I noticed the "register on network" button seems to force the phone to reaquire the network if there isn't any signal. I would be nice to write an app to detect a "no bars" status on the phone and get it to hit the refresh button (or at least call the function) every minute or so until it finds a signal.
Any hints?
I may be hoping for a little too much here but it never hurts to try right? Thanks in advance.
XDA fails tto turn on phone
This looks a lot like "XDA fails tto turn on phone." in http://www.sourceo2.com/Communities...tm?frameset=found&NewsGroupID=8&iPageNumber=1.
Thanks for that I'll have a look-see. Didn't know about the SourceO2 site's communities.
I checked the site and it seems that it's pretty much the same gripe everyone's whingeing about. O2 doesn't seem to say anything about it and some poor guy called "xdaguy" seems to be taking all the heat. I don't envy him.
I'll live with it a while longer if not, it's back to the store and since there doesn't seem to be any other PPC phones apart from the XDA here, it's back to the treo.. Booo Hooo.. No MP3's for me anymore
Thanks for pointing me in the right direction anyway.
Paper clip to boost signal
Yes, a paper clip...
I too have experienced just the other day A weak signal to a no signal at all...anyhow here's how to dot it ( at your own risk of course)
1. Bend to straight the paper clip
2. Strip the plastic cover off the metal paper clip using a blade or a small box cutter.
3. bend 1/4 of an inch at a right angle
4. Remove rubber cover beside camera lens
5. Insert the 1/4 inch bended paper clip into the female socket
6. wait for signal
Note: this is only TEMPORARY of course as am looking into the after market antenae booster
hi - looking for a solution to this. is there any?
if my phone loses the signal it won't regain it.
I'm sure i read somewhere that this is actually a design fault and the xda (version 1) is only designed to try to regain signal for 30 mins then give up. That right? Can it be fixed?

I used to get this but a soft reset usually got it back online.

[Q] How accurate is your GPS with out wifi on?

I ask because with my iphone 3g It was pretty much spot on all the time. My atrix on the other hand is about 4-5 blocks(WTF) off. This is only my second smart phone but this seemed really odd to me.
Anyone else with inaccurate gps with out wifi on?
Mine is usually accurate to within a few meters, but I don't let it use wireless networks for it basically ever
I played with this a bit more and for what its worth it turns out that if the gps cannot get a satellite connection it does not warn you. For me it was just defaulting to the center of the very small town that I live in. Which is pretty much within 4 block range no matter where I go. The 'Navigation' app does warn you if it cannot get a connection.
So yeah, the gps is good, when it connects
GPS is usually within 20' for me. Wifi is useless w/o a wifi source to connect to. No wifi when I'm out running on trails. And if I'm at home, don't really need the gps.
My GPS is dead on all the time. Only takes 3-5 seconds to get a lock at about 3m and that's indoors. Only time I've ever had a problem with it was while using shopkick in a deadzone inside Wal-mart.

[Q] A way to prevent cell tower hopping/switching

Is there a way in either the settings menu or an app that will prevent the Photon from constantly looking/pinging for a stronger tower? I have determined that once locked onto a tower and it stays locked (or locked onto wifi), my battery life is actually very good. For example, at lunch, I sit in my car for about 45 minutes connected to one of the 4g towers and am using the phone the whole time while listing to music/podcast and using the internet and I start with a full charge and will only lose between 10 to 15 percent of the battery.
However, where I actually live are a bunch of weak coverage areas. While sitting in the school car pickup line for about 30 minutes I will typically lose close to 40 percent of the battery and the temperature goes up to 107 – 110 while I do nothing with my phone. My normal temp is 93 – 95. I used one of the locale apps that tells you what cell tower number you are on and in the 30 minutes I was in the car line it connected to seven different towers switching between them all many times. The cell phone tower pinging also happens when at a football came (Bucs, Raymond James Stadium) because of the amount of people trying to use their phones. There is no possible way of making it through the six hours without the phone dying.
So my question is – without going into airplane mode is there a way to prevent the cell tower hopping? I would rather have a constant weak signal then having the phone constantly looking for a better signal.
I am rooted on stock rom.
I don't think so man. Cell signal plays a huge roll on cdma phones, obviously the better signal you have the better battery life. Ive never heard of a way to prevent cell tower hopping as these phones are programmed to link with the best tower it feels will offer best signal. Sometimes you'll be on a Verizon tower and that may be the best one around or it may be the worst but if its closest to you your phone will possibly connect to it. You don't have to turn on airplane mode; i use the data saver profile that only uses data when the screen is on so when screen is off i save a **** ton of battery because the phone isn't trying connect the radio.
This is the only feature remotely close to what you're asking and it won't prevent "tower hopping". This will just only connect to sprint towers if you choose "Sprint only" resulting in probably even worse battery life.

Thanks for your input. I was reading some of the other threads hear and found what you show in the picture. Mine was on any cdma and I switched it to auto as it was suggested it might help with 3g.
I am going to see how automatically performs today when I pick up my kid. Tomorrow I will switch to sprint only to see if that makes a difference.
I will report tomorrow evening with findings.
If we can get custom radios for the phone that should make a difference. The radio (afaik) contains the algorithm for determining which tower to connect to based on the PRL, among other things.
What battery setting will restrict data to only when the screen is on?

Go to settings and battery etc then find battery mode. Works like a charm i.swear.

By turning off data when screen is off , will data sync automatically when I wake the phone up?
Also, switching to automatic in the settings did not help while in my kid's car line at school. I am going to change to Sprint Only tomorrow and reboot before I leave work. I did not reboot today when I changed to automatically. Not sure if that makes a difference.

Yes when u wake up the phone it will sync everything.
Just an update. Today my phone has never been better with battery and cell tower switching. The only other thing I did was reboot after changing to "automatically " . Real test will be this afternoon.
What really stands out is the battery tempature. At idle it is in the low 80s. After heavy use it is in low 90s. Maybe I did get lucky with the change.

Abnormal Radiation issue with st18?

I've noticed that my recently bought St18i is kinda strange during calls.
After just 30 sec I get headache and warm around the ear exposed to the call.
This thing didn't happen with Htc diamond 2. I just can't use the cell close to the ear.
Previously I used to get this kind of sensation after at least 1h of continous call.
Instead with this phone it's enough just 30 sec..!
So I was wondering, does anyone here have experienced this kind of issue?
Hello,
That depends on the band you are using and how far is the tower.
The higher the band and the more far is a tower - the more power it will emit.
These days you should always use wired hands-free device as we are getting more and more electrostatic load and various power wavelengths.
I doubt your unit is emitting more, they all undergo checks and tests, unless you bought it from black market Indian makers.
It's natural that the phone and the area around it will get warm during calls, but it should not be cause of headache.
All our cells and atoms are vibrating, we always disturb it with various types of frequencies going trough our body.
Take care.
Well I'll make more investigations about this matter, I want to check it with EMF meters.
Who knows whether an EMF meter is enough or it's needed also a gauss meter...
I have a Ray in USA (unbranded st18a) and I don't have these issues. The phone doesn't even get warm on two hour phone calls. Worth noting is I have excellent reception where I am usually. The phone really shouldn't get warm, especially enough to feel against your ear!

Buy it in marketplace, or get Nokia Drive, this you can get for free..
Hi. I use Navigon 4.1 on my HTC Mozart. Did anyone noticed that after using the program for more than 20 mins, the phone turns very hot (i never imagined that a mobile phone can turn this hot). I used it a few times to go to a city 80km and after reaching, when i touched the phone for turning off the navigation, it was really hot. The screen stopped responding to my touch, and I had to cool it in front of the AC for a few mins before it became responsive again. (My guess: the program stresses the processor to near max capacity all the time)
I tried the same distance with nokia drive, and everything was normal. There was only slight heat production (I guess because of the screen turned on for so long), but nothing like when I have navigon on.
Does anyone else has this problem, or am I the only one?
Any reply would be helpful.
Thanks.

I know what you say. For me the phone was very hot too. I drive with it about 1100 kilometers, from Hungary to Italy, this summer. When I touched the phone it was about 50 Celsius degrees. But for me the touchscreen went without problems.
My mozart screen normally gets hot when i play for long minutes or when gps on... so i think its normal, or maybe another general bug among the mozart family like the touch problem...
