Hi Guys !! I currently own an optimus one running on stock froyo 2.2.2 (unrooted). Quite a few times (including today) I noticed that the icon showing signal strength in the notification bar blinking. Whenever I return from my college to home via bus..I find the signal strngth changed to null. At college signal strength would be like( 3 out of 4 bars) but at home it stays at full strength. But the day I go to college and return home ..on the way i find my signal strength on the top most notification changing to null for 2 seconds & then returning to full..again going back to its previous state & returns full & again....(fluctuation takes place aft 2 seconds each). Even after I return home where signal strength is supposedly full...the problem does not vanish unless & until I restart the phone. after restarting it doesn't fluctuate anymore. Why does this happen & how to get rid of this ? Pls note- I am on Airtel 2G network with network mode- GSM only. As most Indian users know airtel network is superb !! & I too stay in the capital city of my state so there's no chance of poor signal. i think it's a hardware issue. what u guys say ?
1 more query- can someone provide me the download link to android 2.2 firmware for indian optimus one. I found all the download links to have got expired except for 2.2.2 (v10d). main reason to downgrade-to be able to run ndrive on my phone. pls note that ndrive doesn't work on other optimus one's which come with android 2.2.2 preinstalled.
I wonder....
Airtel's signals are very strong even in the remote areas...
i dont think your hardware causes you this problem it could be your sim card
try changing your sim card and if necessary change your number as you say you wanna be on airtel so buy an another airtel sim and try your luck
or else borrow a airtel sim from your friend and check if its working for you...
If not switch on to vodafone as i did
I was also encountering some problems like gps can locate me.
So i switched.
Vodafone is also good if u try.
sure. thanx 4 replying
Hi all. Like my title says I'm thinking of switching to T-Mobile from my ATT Note because I get NO service in my house with ATT and want to switch to prepaid plans. I know T-Mobile has wifi calling capabilities which could solve that issue (albeit start another one cuz t-mo service in the rest of the area isn't that good). 1.) What am I looking at to switch my i717 to t-mo service? and 2.) What do I have to do to get the wifi calling capabilities working? I did see some threads about flashing the t-mo note stock rom getting the wifi calling working. Thanks for any help I can get.
Well ....
It's impossible to tell you that your service will improve by making the switch, as your service issues may follow you regardless of the carrier.
Not all areas get good service ....and if you know others that are getting good service, then I would certainly quiz them about it.
The note can suffer from antenna issues as well, and the switch may not help.
Beyond the obvious, some note users are having sim issues after rooting and switching over to t-mobile via carrier unlock.
This is a random, but serious issue, that causes the device to fail all network connection.
Until a fix is found, users wanting to use the ATT note on t-mobile, are taking a higher than average risk when switching.
If you are looking for more information (highly recommended ) then you will want to visit the " note super everything thread "....located at the top of the general note section.
Please do your homework there, as you "will " want to learn as much as possible.....g
Have an att galaxy note. Unlocked and running tmobile. Ics. Blaze tmobile.
Problem is that when i call ppl they say tgey cant hear me at all. It was working fine teill yesterday. This started this morning. Anyone else have this problem ? Im new to this phone . Is it a known issue ? Its really frustrating. Thinking of selling the phone.
Please help out guys
Same here
My wife and I just bought two new Notes on US AT&T - same issue - you can hear the person on the other end of the line, but they can't hear us. AT&T says it is a known issue, just pull the battery as the device gets stuck in headset mode (whether the green light is on or not), and this will reset it, but only temporarily.
We're also having issues with Bluetooth connectivity and Wi-Fi signal strength.
Hi All,
I've been a visitor to XDA for couple years now and greatly appreciate the people who post here who have helped me to custom my Galaxy SI, SII & SIII with generally no issues. I've had my SIII for about a year and a half now running CWM & CF root with either Darky's ROM or a Nightly build of Cyanogen Mod.
Since moving to a new house (few weeks ago) the signal on my handset drops as I make/receive calls. I assumed initially it was just the signal in the area and as I had been running a non-stable build I flashed a full release to be certain. I chose Delta ROM initially but have since flashed Darky's, Delta (again), Cyanogenmod (Nightly, stable, unofficial 11), multiple different Modems when running CM (area specific, model specific & the emergency one for EFSv2) and followed the guide to reset to stock (unroot, official recovery, reset counter & stock ROM) none of which has helped.
To be specific, I can use the Wi-Fi, 3G, send texts and use apps which use 3G to send texts (MightText); which to me (Novice at this stuff) seems to indicate that the 2G & 3G functions of the phone work. Yet still as I make a call, or receive one, I do not hear ringing, person speaking or any form of buzzing; this applies if I use the phone as normal, the speaker phone or a handsfree set.
Roughly 30 seconds into the call the network drops (signal bars go empty), the phone call displays 'Out of Network Area' or some such, the call ends and the phone returns to the home screen where roughly a minute later the network reconnects and I can use 3G again, send texts etc. as above, except still cannot make calls.
I don't know if it has any bearings but on Cyanogenmod the time before the network drops is around the 45-60 seconds mark, all other ROMs disconnect at around the 30 second mark and my GF has an S4, on O2 as well, and the signal on her phone has been temperamental lately, but has not shown the same problem, she is running Stock firmware without root etc.
If I had to replace a component instead of sending off to service centre, how difficult would that be?
Thank you in advanced,
Martin
If it still has the same issue with full stock rom then it's hardware, motherboard/antenna etc. Unless you often dismantle and successfully reassemble mobile phones it isn't recommended to try yourself.
Samsung give two year limited warranty, worth trying with service centre after resetting counter.

Yeee I had a look around alot of forums for similar issues but could only find posts where there was no signal at all or playing up due to modem etc.
In desperation I opened dialogue with an O2 Guru who said hardware, but just seemed very coincidental to have happened when we moved =/
Thank you for confirming though worth a shot!
Martin
You moved so you may not have the same signal strength .
You need to work out if it is the network or the phone .
Try another phone in your location with your sim .
Test your phone next to an O2 mast .
Wipe phone flash stock rom for your network and test .

The O2 Guru I spoke with said the signal at my home address should be OK, my GF has an S4 on O2 and although a bit crackly, her phone functions works and I have my SIM in a temp phone, a Galaxy Ace, which has also been working fine in the area.
It's a good idea to test closer to a mast, I don't know where the nearest one is to be honest, is there anywhere I can find this out?
My phone is currently flashed back to stock, that's recovery, ROM, counter, modem (I believe) etc. followed this guide to do so:
http://forum.xda-developers.com/showthread.php?t=2323847
What boggles me is that the phone is able to send texts, use 3g and search for different networks to 'register' etc. but the phone call disconnects. I would have thought that the same component which connects to network to send texts would connect to make calls? Is it possible that where I am in a weak signal area, the phone has damaged the component by increasing the gain by too much/for too long? If so is that because there was custom software or would the settings for this component be the same as stock?
Bit concerned about sending it off and the possible questions/costs associated with this sort of thing. This is the first time I've had a phone which has a hardware fault, all the other times a phone has played up its usually due to the software which can be flashed using any number of methods found on this site.
What a frustration, sorry to ask so many questions, just at a bit of a loss as to what to do with it now!
Thanks,
Martin
In a weak signal area your phone has to output 10x the signal strength to maintain voice call, which it probably didn't have to before. Data and text use much less power, hence why they still work. To test just find somewhere with full bars strength, maximum ASU value in settings, about, status.
It sounds like a high resistance gap somewhere, it gets hotter during use until it breaks the connection - then cools to join again.
Just make sure you describe the fault correctly and it should be repaired.

Hi
I bought samsung s3 in previous 6 months ago, after 3 months I got frustrated problems that cause my phone low signal even no signal, frequently s voice is talking itself and the screen is on, the screen is on even I press power button. And I google, I found that many forum but I can't find any solution, and I decide to upgrade firmware 4.1 to 4.2 I was hoping that can solve my problems, upgrade firmware can only solve screen on and s voice, still no signal and week signal. And I upgrade it to 4.2 to 4.3, it worse than 4.2, now s voice is talking itself, no signal when enter house, in living room. Sometime the screen is on, I can close the screen. I assume that this is firmware mismatch problem, but I am not sure. Any suggestion is greatly appreciated.
Thanks
