I bought an s3 a week ago on ebay. That was my first mistake the signal strength is awful browsing the internet without wifi is really bad it can take up to 5 secs to load google. Now my wife has an S3 with tmobile uk and hers is fine. Mine was originally on vodaphone but I am on O2 I have put her sim in mine flashed to the same stock rom and my s3 has still a poor signal normally two bars. Just tested I get -105dbm and 4asu. I can only conclude that after trying every network rom combination my phone is faulty. I had no joy with the ebay seller I am not sure I could take it to vodaphone as I was not on the original contract. Any idea guys how a resale affects warranty, ideally I would like the handset replaced or repaired. Lessen learned not to try and get an ebay bargain
How much did you pay for the phone??

I've just looked at the status of my phone and I'm getting 95dbm and my phones fine, where do you live?? I live in hampshire on vodafone and the signal here is variable, despite living within a cats throwing distance to the cell tower (5mins walk)

Have you tried flashing a different modem. I flashed lf2 modem and my signal strength was back to normal it was bad with lfb

As stated, try an alternative modem which has resolved my network issues previously.
If it is still not resolved, contact Samsung - don't mention eBay purchases - the serial number will show up fresh on their system (tested with known blocked handsets lol) they will organised a repair; and 9/10 times will not request a proof of purchase unless referring you to a local center; but this issue would be hardware related so they will request sending it in. Just ensure you go back to stock.
thanks for the info. I expect Samsung should repair anything as long as the iemi number is not reported as stolen.
tried the LF2 modem and its made no difference, however I have used an tmobile sim this morning, signal strength is the same but 3g/H data is working really fast, now I am wondering if my data on my o2 sim is poor as its cut down microsim. going to get a proper 02 microsim and test again

As long as the gold contacts on the bottom have not been damaged it will have no effect - plus it wouldn't effect data tbh as all the phone will do is read your networks information and they send/receive the data. But feel free to try; I personally have noticed that 3G/HSPA/+ is a lot slower on O2 compared to any other network tbh - but then again these data connections for O2 has only recently been added to my area, up until a few months ago the fastest we could get was Edge on O2, while the rest of the networks in my area has had 3G for at least 2 years lol.

I have read somewhere that some people are experiencing their data connection to freeze or have idle times even with good reception.
Now I have never had an Aussie firmware, in particular the modem part of the firmware which I believe is the part related to the phone performance?????
I have tried disabling and enabling the fast dormancy. Turning off data and enabling it again fixes the problem. The hang isn't permanent so things like email, syncing, weather all update fine, its just web pages can sit loading for ages or time out with no acitivity shown. But try again a few minutes later and the internet is super quick without the reception of tower changing.
Does anyone else with Optus Australia, or vodafone or telstra for that matter, have the data stalling issue? What exact modem version are you using?
Yeah i think this is actually related to Optus's network.
I have scrubbed my phone and applied the XXKH3 firmware and it seems a bit better to me. I also disabled Fast Dormancy.

I have too agree with Simmo3D the current state of not just optus is abysmal.
But there is a light at the end of the tunnel with the NBN it should is ease the congestion that we have been having to deal with because of the explosion of people updateing there facebook status.
Also we have both telstra and vodafone putting in new 850MHZ tower which can handle a much larger amount of traffic which means the Que time or "Idle time" will be reduced.
I had wondered about it being Optus... but turning data off and back on straight away seems to fix it instantly so wondering whether it isn't because of congestion otherwise it wouldn't always fix the problem temporarily .... but I am no expert. It isn't a slow down, its a complete stop with no data going either way. Occasionally it will sit there sending permanently but that isn't always the case when it stalls.
I am not disagreeing just trying to confirm whether this is definately optus or something else related ot the wrong modem component for optus network.
I never noticed this on my previous phone (i8000 on win mo and alos a buggy android port) but to be honest I didn't really play around on the net so much because I didn't have anywhere near this amount of data I have now and it wasn't as appealing to play round with online....
Were either of you on Optus with another phone you used data on a lot? Did that experience the same stalling of data.
no problems on telstra here
My dad is optus and has the same issue on his phone. Me and my gf are on Vodafone and have a slight issue but not as bad becuase were mainly on the new network. Telstra finally turned on QoS so there is no problem on that network.
Remember there are 800 open cases with the ombudsman over optus's delivery of service.
There are tweaks to the build.prop file to mitigate phone issues but won't help as much as if optus fixed there infrastructure
Sent from my GT-I9100T using xda premium
Thanks all. Looks like concensus says optus is the main culprit and i don't need to head down the flashing of a typical optus modem firmware with my imported phone to fix these dramas. Thankfully its not all the time so I can live with the slight frustrations at times. At least the voice calls aren't doing the same thing...

As far as I know there is a known bug in the phones software that stalls data transfers when switching between 3g and h. The fix is to lock the phones data out of h.
To do this use the stock phone dialpad and key in *#301279#
Select option 2
Select option 1
Then use menu key and go right back or end.
Should not be using h network now and your stalling should be fixed.

i thought this would be the best place for a problem i started having about2 weeks ago. i am on vodafone uk.
i used to get 3-4 of the 4 bars reception while sitting at home(as an example). suddenly i was getting 1-2 and sometimes none (all blank).
i thought i would try and eliminate things one by one so here is what i did...
checked with my sim in another phone and another sim in mine. from memory the other phone having my sim was slightly down but not much and my phone with the other sim didnt really change much.
i checked with vodafone by calling them, they said they couldnt see any problems on the network, birmingham uk, but would send a new sim, after getting the sim activated when it arrived, no better. their onling forum is still waiting for a response back from their technical whether there is any problems. i dont see how the phone department can instantly tell me when the technical need many days to find an answer.
i thought it could be the rom so i first updated lite'ning rom to resurrection remix and then to a later version of RR and no change. the newest version of RR has a different kernel, flux i think, than the siyah in the 2 previous roms but again that different kernel didnt improve it. lastly i even changed the modem/radio trying to different ones to the default, xxlpx and kh3 and again no difference.
the only thing that improves it is turning 2G on instead of 3G. the bars go back up to 3-4. even with 3G on previously as i never changed it before it was always fine.
i know this is a long post but i wanted to be thorough as i really appreciate any help as i am now lost as what could improve this.
Mispost
anyone?
I have been having a similar problem on Three for about five weeks now. Despite numerous reloads of Android and modems etc I was getting no results, 5mb dl speeds have dropped to around 150kb despite having a good signal.
After many many calls to so called customer service I have discovered that a new cell tower near to me has been activated as part of the network expansion program and because this cell is closer to me than the one I used to connect to I now get a stronger signal from this so my phone always chooses this. Problem is this cell has only got a 2mb feed INTO it, its a TMobile/Orange cell now being shared with Three....so I am basically fooked.
Check with Vodafone if they have done anything similar recently near you. Three are adamant there are no problems my end, technically they are correct I suppose, its all working, I just cant access the net without it timing out constantly now.

I am having the same issue with my phone. I get only one bar (sometimes none!) whenever I'm home & I'm on WiFi; however, I get full signal strength when I'm out & on 3G.
Sent from my GT-I9100 using XDA
i thought it could be the cell tower thing as there is only 1 vodafone one in quite a large radious, about 2 miles, and many of all the other networks. i dont know why vodafone are happy to have 1 compared to at least 3-4 each for all other providers.
this morning i drove that 1 mile to the vodafone mast and ran fresh network and surely that would have connected to that as i was 5 meters from it. still no better. ??
Just try NELP3 modem once... I had done similar issue once.. Now my network is better..
is nelp3 okay for uk though?
Try flashing another Modem. Im from Germany but i had similar problems. A new Rom would do too i think

not sure what you mean with 'all'
Number of options, tower may be having problems, maybe some form of interference, try a different modem, try different sum card if you have one spare?

i do have the same problem as above, no signal in the building and 50% signal outside building. I swithch my SIM with fren's (he use another telco), and his SIM not work on my S2 and my SIM work on his phone (not SIM issues).
I tested many modem as recommented , LP2/LP3, LP9, LPX, KI3, KI4, KF2, no luck.
I flash different ROM, (some old version that work before), from CM9, AOKP, Sammy. no luck.
I restore old back up ROM. no luck
Fix permission, no luck.
any advice ?
OK next step is to flash a different modem
Sent from my GT-I9100 using xda app-developers app
i've tried a few modems including the ones people believe better, all have this problem so far.
it may be the network mast in my case. i discussed with vodafone what 3G mast i was connected to and then which 3G mast is next closest. i then went right next to that other 3G mast and the signal was full bars, no fluctuation at all. this surely means it is either, 1-the network mast i keep locking to having problems or 2-all the modems i have used favouring battery over strength and not getting enough power to get a good signal.
is there a way of finding out which modems are better for battery and which are better for signal strength?
Umm not that I know of, best thing to do for that is either research the modems for better strength or battery etc, or just test some yourself, however that is time consuming,
Personally I think it is just the mast having problems, however I may be wrong
Sent from my GT-I9100 using xda app-developers app
i thought i would add a little research to this thread, not too much but just my experience with 3 specific modems.
the background is that recently i have started getting very poor network signal as i believe the closest 3g mast to me is having problems. if i turn to 2g its better as the phone then connects to the closest 2g tower which gives better network signal.
i know that a modem should be left for 2-3 days before judging but i thought that if a modem is currently better than another then that is only likely to stay the same with time as long as they were given the same short period of time.
i used the app network signal info and did 3 5 minute tests for each modem and then averaged the percentage of the signal and also averaged the -dbm also.
i first used the modem i currently had on there, BUKI1
- average percentage was 19%
- average -dbm was -103
both very poor scores
the signal was very jumpy up and down also
i then flashed the custom modem, i think by krs007, M250S
- average percentage was 44.6%
- average -dbm was -90.66
obviously a huge increase
the signal was very steady, hardly changing from that average
lastly i flashed NELP3
- average percentage was 30.66%
- average -dbm was -97.33
better than at first but not as good as M250S
i am now going to let M250S bed in for a few days while keeping my eye on here for how NELP4 performs but so far i have a huge increase in signal in a previously very poor area. as this is also due i believe to the tower having problems, hopefully it will only get better.
Try downloading OpenSignalMaps from Google Play Store. For starters, you can determine the approximate location of the offending cell tower (if the cell tower was indeed the culprit). Sometimes, i realise that the phone tends to stick to certain cell towers when others are in closer range and could purportedly provide a better radio link. For this, the app provides a refresh feature that allows you to manually trigger a cell tower refresh. I am aware that most apps requiring connectivity have this feature but i don't suppose you can call the refresh on trigger.
Hi Marc
Tracked down a copy of M250S(dont know if its the same as you have installed though), and very briefly, as in 30 secondsish, I had 4 bars and dl`s around 5mb again!.But midway through it dropped out and that seems to be the pattern. Seems to be having problems locking onto a cell, signal bars frequently grey out, maybe its a compatibility issue with CM9, I dont know.
Anyway, let us know how you get on,
Cheers
Chris
it probably is the same as i dont think any others have that name.
it probably just needs to bed in for a few days. i have noticed mine go between 3g and H quite regular but it always does that, i havent had any dropped calls or similar so far.
Ok, here's a challenge.
I am a uk t-mobile subscriber. In the uk t-mobile and orange merged their cell networks into one big network (tmob bought out orange) with the original t-mobile cells still showing up as "t-mobile" and the now merged orange cells showing up as "t-mobile orange". Tmobile offered their subs the option to also connect via orange cells and orange the same to their subs.
At the time i thought this was a good idea. More cells, more signal in more areas, better experience.
I was very wrong.
Basically the orange cells are absolute crud compared to any of the tmobile cells. You notice a massive drop in bandwidth between a tmobile cell and an orange cell and i wish i had never opted to use both.
So, i am looking for a method to allow me to block the switching to the orange cells so i can stay on my native (faster) tmobile cells all the time and never ever have the phone connect to an orange cell ever.
Any ideas?
I know each network has a numerical value that denotes it so there must be some way to tell the baseband never to switch to this particular network right?
Any advice anyone can give would be greatly appreciated. Cheers.

I was looking for the same solution and came accross your post, judging by the lack of replies theres still nothing to sort this out. Annoying when Orange forces to take over and is usually a weaker signal!
A Post in Themes section re call blocking .
Dont know if that dev would have more knowledge .

I thought you could manually select the network? TMo and Orange come up separately as an option there?
Sent from the town of Waterlooville
I'm also looking for something so I can select a mast... the closest mast to my home is only 2.5mbit while a mast just a few miles away is HSPA+ and peaks at over 10mbit.. when my local mast was down I was able to connect to the HSPA+ one and have full bars... there must be a way of telling the phone to ignore a mast?
You can manually select the network in network settings however the phone freaks out then whenever there is no signal instead of quietly waiting for new signal.
This sort of solves the problem but creates the additional annoyance of notifications of no signal.
I couldnt find any way of blocking individual masts. Im not sure it can even be done on the user end.

Try updating to lg8 firmware with lh1 modem.
I'm on orange/t mobile and everything works much better now as far as the network switching goes
did you ever get a solution to this ? Orange is doing my head in and its just terrible..
personally the reception on my s3 is horrible. I live in the US and use my s3 on at&T's network. I constantly see 1 bar of service. I never noticed such problems with my s1 or s2, but don't have them any longer to really compare.. can anyone else give feedback on how the reception on their s3 is?

Which modem are you on. Please try DXLF3 if you're not on that modem yet.
Mine was really bad with Stock ROM (ALE8) and provider-pushed APN settings. Kept jumping from antenna to antenna and fell back to Edge all the time.
Removing the proxy server from the APN settings helped with the antenna jumping
Flashing eastern modems (particularly DXLF3) fixed the' falling back to edge' problem. In fact my connectivity is now as good as the S1 with it's Hong-Kong modem; Working HSPA throughout the forest (daily dog-walk) even if often one or zero bars.
The S1 had a terrible stock modem too at the beginning.
I'm based in NE England and work in an office with 5 other S3 users all of which are on EE. 2 bought Sim free phones and use an originally Orange Sim, one has a branded Orange phone and one has a branded TMobile one. The other person has a Tmobile 4G phone. The only one that isn't stock is one of the Sim free phones (mine)
All but the 4G phone lose signal several times a day but show 3 bars. There is no data connection and the phones cannot make or receive calls. If they are reset or toggled between 3G & 2G then they work again for a while.
This behaviour happens at work and at home. No other phone user has this problem - there are a few iphone & non smartphone users who gloat constantly
Anyone else suffering as badly as us?
All fine here. Sim free phone under TM contract.
Under carrier it says either TM/Orange never EE for some strange reason.
Exynos SIII; CM10.1
why not post in the help section?
Try different modems and make sure ril/modem match
Here's your answer: EE sucks!!
Lots of people reported signal loss on many different devices, I'll blame EE not S3s.... I've got one of my phones on Orange and since EE showed up, I'm experiencing signal problems as well. Many times people trying to call me, my phone shows full reception but is unavailable and voice mail kicks in!!!! It's annoying but this behaviour is a Network fault. Nothing to do with phone imho.
The only thing you can check is Baseband version (modem) of all phones and compare to the one which works fine. Maybe all except one have wrong modems installed. Unlikely but can happen
Next time use Q&A section to post your problems or questions..

I'm in the south also, no problems here, in fact excellent!
I get bandwidth issues and signal drops. Been on orange & tmobile for years and it only became an issue with the arrival of EE.
Most of the time the signal/speed is great tho.
