Strange phone issues with Samsung Galaxy S

Hi,
I bought a Samsung Galaxy S about a month ago, and have been having odd problems with it since the off. Has anyone else had these sort of symptoms:
1. I occasionally lose my data connection - the icon disappears from the top of the screen and whilst I can still make and recieve calls and text messages, I cannot download anything in any app. The only way I've found to get my data connection back is to reset the phone. This happens maybe a couple of times a week.
2. My WiFi seems to suffer from a similar problem. I can be browsing the web on Wifi, then suddenly I'll not be able to download anything anymore. The wifi icon is still visible, but I'll basically be unable to download anything until I switch the wifi off and back on again. Then, it starts working as normal again.
In both these above scenarios, I think I've narrowed it down to primarily happening after I use the Android Market, but it's difficult to tell as it's very intermittent.
3. A couple of times since getting the phone, I've been unable to make or receive any calls. Even switching the phone off and back on didn't help - my signal bar was showing I had a signal and my data connection was still active. Couldn't tell if this was a network problem or not though as there weren't any people nearby on the same network as me. After a while, it started working normally again.
4. The email client randomly lost all of my email settings. One day I was receiving all my emails, the next day I had no email accounts set up at all.
5. I installed Sensor Dump and Phone Explorer to see what data was coming in from the sensors, and have noticed that the light sensor never sends any data. Is this normal?
I also have the usual slow-down issues, etc, but the above have got me stumped as I can't find anyone else reporting the same issues. When I first got the phone, I went crazy installing a load of Android apps, so initially I blamed the software I'd installed. After a reset and being a bit more selective with the apps I install and use, I'm still getting the same issues. I just can't pin down whether this is a faulty phone that I should return, or if there are software issues either relating to the way I'm using the phone or just with bugs in the firmware.
Has anyone else had anything like the above happen with their Galaxy S?
Thanks,
Chris.

I've experienced no.2 several times, wifi just stopping all data traffic. Not found out what causes it though.
As for the other problems, I haven't experienced any of those. Do you use automatic brightness on the display? If not, problem no. 5 might be caused by the sensor being turned off.

thanks for the reply - at least I'm not completely alone!
I have the automatic brightness turned on - which is why it seems odd. To be honest, I've never actually see the auto brightness do anything. It always seems to be the same brightness to me.
Cheers,
Chris.

Hi,
I've experienced no.4 some times. My inbox did not show some older mails.

I think it might be normal that older mails disappear from the inbox after some time? My problem was that everything went. I had three email accounts set up, all downloading emails every hour. Then, one day I went into the email app and there were no accounts at all! I had to set it all up from scratch again.
I hear there are better email apps available for Android, so I'll probably switch to one of those soon.

anyone have the solution for this?

Hi,
I bought a Galaxy S on Orange UK in July. I'm having the same problem as 1. quite consistenly now.
I thought it might be related to the green power battery saver app I had installed, but i've removed this and still having the problem.
I'm using the phone in several central London locations so I think it's unlikely to be a problem with the data network.
Any suggestion would be welcome since I'm often without data.
Thanks
Nik

ive 1 and 3 but very rarely so far
rebooting fixes it for me
running froyo jp3
for email i use K9, it's almost the same as the integrated mail, only much better (PUSH imap)

I'm actually getting this happen a lot now. It seems to be getting worse, which makes me think it might be a hardware fault. I generally lose my data connection once or twice a day minimum, but some days the phone is virtually unusable.
I have found that it's more likely to happen after using Wi-Fi, so my other thought is that when coming out of Wireless mode, the phone may not switch the normal 3G/HSDPA data connection back on. Most of the time I can fix this by putting the phone into flight mode and then back out, but sometimes it needs a complete reset.
The other problem I've noted with the data connection is that sometimes it seems to rapidly switch between HSDPA and 3G - the data icon at the top of the screen keeps going from '3G' to 'H' then back again. I guess it has something to do with signal quality but it only seems to happen when the phone is showing a good signal strength (four bars). The problem I've found when this happens is that it virtually locks up any ongoing data transfers, making it impossible to download a webpage or check my emails. Strangely the only way I've really found to stop this happening is to move somewhere where my signal strength is weaker, such as indoors, which then seems to make the phone stop attempting to use HSDPA. I can't find a way to switch off HSDPA from within the phone's settings while leaving 3G on.
I really am now finding that using this phone is an increasingly frustrating experience. I've found even more weird faults, such as sometimes my text conversations show the wrong people's names up against them, and then my replies go to the wrong people. It's like an insane, shiny mess of a phone!

I am indeed experiencing same problems above..it just drive me crazy with a need of complete reset everyday..
turning on n off flight mode won't change anything..
I really hope someone can bring a miracle to solve this problem..
I'm on XXJPC

setting the APN parameter(Setting-->Wireless and network-->Mobile Networks-->Access Point Names-->New APN) to 2G only seems to solve the 'lost data connection' problem..
I am connected 24/7 now..
Give a try guys!

[Q] my G2 loses service, restart brings it back

hey everyone
so my G2, which I absolutely love, has been having a problem lately. in the first week it happened maybe once and i didn't think much of it, but since Friday it's happened like 8 times now. I'll be sitting there with my G2 and all the sudden I have no service whatsoever. Just an x on the signal strength indicator. 1 or 2 times it has come back after a minute or two, but the other times I had to turn the phone off and back on. the weird part is I'm not moving at all, totally sitting still, but when it comes back on I have FULL bars with HSPA+. so it's not like I walked into an area that didn't get good reception.
any idea what's going on? i looked around but didn't see other people having this issue. any ideas?
thanks

alright well at least i'm not alone. i remember that rumored OTA update was supposed to have some radio bugfixes. maybe when the real OTA update comes it will have something to fix this. i hope so.

I have been trying to diagnose this issue on my phone too.
By any chance, do either of you have your BT on at the time?

Happens to mine as described and I have never turned on bluetooth. However this would also happen to my G1 so I think its a network thing personally.

Yeah, it definitely is. I have 2 areas that it happens in, both are while I am in my car and I have BT on in my car. When I ran it without BT, did not happen.
I have found that when I am in those area's, turning off 3G stops it entirely, even with BT on, so when in my car, I set edge and still use my BT and problem is gone.
I hope this is temporary and an OTA can fix the handoff from 3G to Edge and back better so that I can stop this, but this works well enough.

Mine has done that also, maybe once a week for the past 3 weeks.
Judging by the other problems you can have Id say this one isnt that bad. Especially if it only happens once a week haha. This is the only problem I have with my phone.

no bluetooth...
no no bluetooth on, i never do actually... but also my G1 never did this, which makes me think it's NOT a network thing, but I don't know.
also I'm sure this is just coincidence but it almost always happens when my girlfriend is nearby with her T-Mobile Blackberry Curve. i know it wouldn't make any sense, but she's sitting there on the same network with full service and all the sudden my G2 loses service completely, right next to her... although it's not always while she's there, but like the majority of the times she's been there.

I just started another post to check on something, I have widgets that show me when I am connected to 3G and when I am connected to H. I have noticed that the phone is activity managing that connection. In other word, it is in 3G until data is transfered then it goes to H. I wonder if when we are in areas of "questionable" HSDPA signal if this hand off is causing the problems.
I have seen a lot of op's say that there problems come right after some data activity?
Just a guess a this point

i saw someone mention in another post that it happens after/during a text message alot of times. i haven't noticed that myself, but that's something to think about too.

What I've heard is that the phone will stay in 3G mode until you begin using data in order to save battery life. Makes sense to me.

My Omnia 7 keeps loosing it's 3G connection

My Omnia 7 keeps loosing it's 3G connection. To restore it I have to restart the phone. T-Mobile say that this happens from time to time, but it's happening every day now. It's annoying as it stops my push email from being up to date, and of course prevents the use of any internet based services until the phone is restarted.
Has anyone else noticed their phone has switching to GSM?

Had mine for 6 days.Been fine up until today,then I had the same problem.Only the once so far.

Confirm loosing 3G
Confirm loosing 3G connection, and also have phone call failures.
Factory reset did not solve the problem.
Bring it back to shop
Blackstone is back now!

At first this was occasional with my phone, then more frequent, and it's all the time. If I want to use the Internet I have to restart the phone. My house is covered by full HSPA, but the only way to get it is to take the battery out while the phone is switched on. I can sometimes get 3G by a simple restart, which I lasts about 40 minutes.
I like the phone, so I'm going to hold out for a software update. All it needs to do is check available networks and I think that, if this is a wide spread issue, Samsung/Microsoft will fix it. Hope so.
Please post here if you have this issue too.

I have also been having this issue... sometimes it doesnt come back straight away when i restart it but after about 10mins its back.
When I activated it with orange I was told to expect a few txt msg's that would need deleting and the phone restarting... I only got 1 msg, maybe this has something to do with it, maybe the phone hasnt been sent enough updates.

I also have this issue and have done for weeks. Orange couldn't solve it either.
It only happens overnight at home. I either need to reset the phone / rescan available networks or turn flight mode off and on again for the connection to restore.
I was thinking it may be an issue with t-mobile since it only happens at my home where orange signal is poor and i roam over to t-mobile.
If i stay in an area with good Orange signal i don't get the problem.
Good to know i'm not the only one with this problem. It's very annoying!

Hi y'all.
I had the same problem: 3G was lost every time. I was fed up restarting the phone every time, so I looked for another way to get 3G back. I found out that disabling and enabling SIM security (phone > setttings) got me 3G again... for a short while.
But: after disabling SIM security permanently, 3G kept on going (in fact for over a week now).
I think that changing the PIN to some other number, might cause this. I haven't yet tried changing it to the default PIN again, to see if using that for SIM security solves it. For the moment I'm too happy it works again.

I have suffered from poor reception issues ever since I got my Omnia 7.
It seems like the reception comes and goes. I will receive e-mails, which proves that the phone has been connected, but as soon as I try to use data myself, by visiting a web page or refreshing an app like facebook, the reception disappears and the "no reception" symbol drops down from the status bar.
Also, often when I try to send an SMS, it will appear to have been sent, yet 10 minutes later I will receive a "Can't send...try again" message. Once I have received this, the SMS will never successfully send. However, in the meantime I can receive SMS messages, which shows that the phone has been getting a signal.
This is SO frustrating and is ruining my experience with the phone.
I have posted requests on the Microsoft Answers forum and the only suggestions have been to reset the phone or turn WiFi off. Neither of these have had any effect. I have never enabled SIM lock.
I have heard that there is a firmware update due soon which includes a new radio stack. I am desperately hoping that this will improve the situation, as at the moment I cannot rely on my Omnia 7 as my only phone.
Alex.

Hi Loco,
You are right in saying that social answers doesn't really help much .
Luckily there IS a new firmware from a couple of days ago! Check out the Omnia 7 Dev section. There are only a few posts.
And here is also a good link for you. You are right to assume that it comes with a new radio stack which improves on performance.

Finally found a thread on this... I have been having a similar problem since I got my phone from Optus here in Australia. I took it back and they replaced it for me but the new phone is exactly the same. I don't lose the 3G icon but anything data related just ceases from loading. Right now I'm trying to refresh the Facebook app and it just comes up with 'Unable to connect', even though I have full 3G reception.
I flashed it to the newer leaked firmware and it hasn't changed anything, problem still persists unfortunately. This is a major problem that isn't getting enough attention! It seems quite widespread and Omnia 7 specific.

Had similar problems, but after I changed my provider ( O2-Germany), 3G is stable.

For the people having this problem, have you tried setting the phone to prefer 3g? Details of how to do this are here http://forum.xda-developers.com/showthread.php?t=915813

Same here man. On Optus and my reception sucks with this device. What the hell is samsung doing? FIX IT!

I have been having this problem with my Omnia 7. The frustrating thing is this is a replacement phone I had for an LG which I had replaced THREE TIMES due to random resets. So now I have a phone that I have to turn off and on EVERY MORNING in order for the data connection to start working again. Needless to say I am very frustrated. I am on Orange in the UK. I suspect it could be related to when being an a poor reception area and it tries to switch to tmobile. I am going to try turning roaming off. Please, if anyone finds a solution to this let me know.
Thanks

My problem got worse with the Mango update. I'm now on my 2nd handset after having a replacement from Orange warranty. This one still loses it's connection but much less frequently.
TBH i don't think it will ever get fixed. I started an MS Answers thread months ago and lots of people had the same problem but we never got a response from MS.
Conisdering the age of the model now I doubt Samsung care, well they didn't seem to care a year ago so they won't now... For this reason I will not buy another Samsung phone. It's infuriating.

Looks like I am stuck with it until December then when I can upgrade to a Nokia lumia. A long wait :-(

i have this issue, too.. but for me i only have to set airplane mode on and off. sometimes i deactivate data connection, go to a random website, get the 'no connection' error, then activate data connection back and it works.
however, after installing the latest drivers & firmware, i get this issue A LOT less frequent. like once in 2-3 days.
i hope ms or samsung will fix this because it can get really annoying. especially when you need eg. a quick google-search..

Just flicking the flight mode wouldn't be so bad but that doesn't work for me, I have to restart the phone each time. I love WP7 but this and the other problems with the LG is driving me nuts. Almost wondering whether I should have just followed the crowd and gone for an iPhone.

Same as me - Flicking flight mode on-off doesn't solve it, needs a soft-reset.
Like I say, there are quite a few with Omnias on Orange with this problem.
I'm in the same boat, I've had this for months now so I guess I'll just deal with it until I can upgrade the start of April and get a Lumia (hopefully the EU 900/910 will be here by then!). There is no way on this earth Samsung are getting any more of my money. Nokia seem fully commited so they can take my cash next time!

I have the same problem with the data stopping working on o2 in the UK. But I also sometimes cant receive calls even though the phone has service, then there are the times where it site there going GPRS/3G/3G+/No Service and you cant do anything with it apart from pull the battery.

[Q] Nexus 4 Signal Strength... Antenna Firmware Radio Problem? anyone else?

I have Straight Talk AT&T, and so far my experience has been mixed. Sometimes I get full reception and generally awesome speeds (coming from Sprint's slow ass network), other times I get absolutely no service, sometimes it randomly jumps into roaming and i can't get data.. and it stays 'stuck' in roaming mode.. I have to turn airplane mode on/off to fix it.
This all happens without my leaving my desk.
Apparently it isn't limited to Straight Talk AT&T though http://forum.xda-developers.com/showthread.php?t=2038963 http://forum.xda-developers.com/showthread.php?t=2037780

same. hopefully they fix all these issues with a new radio. and also losing data while on a phone call!!!

Weird...on mine the bars go all the way down but when i do internet test i still get high connection. Also my internet works fine. Usually bars go down when i hold phone from top right.

sometimes I lose all bars and am still talking on the phone. so strength meter is off and doesn't mean much at this point.

Mine goes all over the place with ST ATT just sitting it on a table

well hows att reception in your area in general? mines pretty steady as far as 1 bar give or take. but theres sometimes I will sit at zero bars all together and still have service. I wouldn't worry about it too much as long as your able to make and receive phone calls etc

So it's been determined that it's not a hardware problem?

well its still early to tell. the phone is still very new so they have plenty of time to tweak the radio and fix bugs. lets hope its not some kind of weak radio hardware issue.

I've been having these as well. Quite annoying, but the data connection still pulls data and works. I've requested an RMA device and should be here tomorrow. Going to test with that, if it's the same then I'd keep this one I already have. Sometimes even if I have full service 5 bars, data will not work. The H will still be on stop of the signal bars, but it won't download/update any data, if I'm using any apps, it'll just hang.

What is the process for going about getting a replacement... and keep us posted on whether or not you see any changes..

let us know If the replacement is better. which I don't think so. but if your on original 4.2 with older baseband stay there. don't update and play with the data then. see if its good. then when satisfied update and see if the same problems arise then you know its software bugs

My N4 pretty much does the exact same thing. Actually, I'm on my replacement phone and it does the same thing as my first one.

which makes me believe its a software bug. or hardware fault. i'm having some faith in software lol :good:

I sure hope it's a software issue, because my connection really sucks. It drops out constantly, but never dropped out a single time on my Backflip during normal hours (only 2 times around midnight during server maintenance or something)

Do you think I should try T-Mobile and see if my issues are resolved..

I just discovered this phone info settings, via *#*#464 or whatever it was.. Is there a particular setting it should be on, not WCDMA Preferred?

I'm having the same problem: the signal strength is very erratic. I'm on Rogers in Canada, which is same frequencies as AT&T.
I've never seen such erratic signal strength before.
On the other hand, though I haven't had it very long and haven't put it through its paces, I haven't noticed any significant signal issues, like dropped calls. So, I don't want to jump to any conclusions that what I'm observing is actually a problem.
Does anyone know of an app that tests the quality of my data connection? I know everyone uses speedtest.net but that just tests burst speed and I'd like something that will test the consistency of my connection too.

same problem
I'm having the same difficulty. Signal can be at 3 bars then all of a sudden goes to 0 bars.
Has anyone determined if this is a software or hardware fault? Any solutions?
Thanks

[Q] Loosing Data Service

This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?

This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.

I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.

Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?

Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?

I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?

I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to
CDMA/LTE/EVDO? Just throwing out ideas

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
