Hello Guys,
I am so desperate and frustrated, hope you can help me!
I dropped my phone from 2 stairways height.
It was working so i didnt care, but when I came home I noticed that I had no reception!
So as I have bought the phone from Germany Amazon.com and using it in Turkey, I had no warranty (even if it said I have!!) I decided to open my SGS2 (I9100) and see if anything was loose. I lifted the pins that touched the middle housing and now I have reception for phone calls all the time thanks God!
But I have no 3G at all, what happens is that is some times shows G in the status bar but never with a + sign near it. I saw + sign only once or twice in the last couple of months.
I called my operator which is Turkcell and they said that my contract is on 3G so no chance on that side. The wierd think is that my phone works with no other SIM card than mine which is 5 years old!
Can anybody help in order to solve my problem? Is there a diagnoses tool that will help me test my SGS2 in order to find the errors?
Thanks for reading guys, I'd really appreciate some help.
Hmm I'd check my APN settings first, make sure they didn't randomly change for some reason. If that failed, I'd factory reset. If that failed I'd flash a new firmware+kernel+modem, and check my APN settings again.
If that failed I'd open it up again, disconenct and clean the antenna wire, reattach and hope for the best.
If that failed I'd suss out what is the most appropriate looking part/area of parts to replace, then replace it with either that specific part, or a pre-assembled part with the surrounding parts attached.
If that didn't work I'd list it on ebay as clearly stating the phone is damaged, outlining the problem and sell it "for parts only". Lots of people pay good money for damaged smartphones. Just make sure any sensitive data/pictures etc have been securely removed before selling it.
The problem with reception was fixed with lifting the pins that touched the middle housing but, stand by :
I think I never had 3G since I bought that phone from Germany.
I feel so stupid!
I read through more and more and I found that article:
androidforums.com/samsung-galaxy-s/258859-how-enable-850mhz-3g-network-frequency-your-samsung-i9000-galaxy-s.html
It mentioned about the modem frequencies so gave it a try.
dialed the number * # * # 1 9 7 3 2 8 6 4 0 # * # * as stated and bingo!
My modem doesnt list GSM 2100 which is the deault frequency for 3G in Turkey!
But the article doesnt mention how I can ADD GSM 2100 from the menu that dialing that number took me.
Any help with this is appreciated!
First, that article is for am i9000, which is the S1. But that's largely irrelevant because the service menu code still works.
Second, this phone doesn't get GSM 2100. Never has. It gets WCDMA/UMTS 2100. GSM is for voice and 2g, WCDMA is for 3g/HSPA. Looks like you went to the wrong option. (GSM, instead of WCDMA, like the article said.)
Third, you CAN'T add frequencies, on that menu or otherwise.
Thanks.
So why is that my phone connects with only Edge?
Can this be a hardware problem where everything else works?
Maybe these setting are wrong? Or maybe it has a SIM lock? but it works with Turkcell
Is there any manual so that I can these settings_

You said above you don't think you ever had 3g. Maybe your carrier uses 3g frequencies this phone simply doesn't receive.
For example, this phone well never get a 3g signal on T-mobile USA's network, because the phone doesn't receive 1700 UMTS/WCDMA. This is one of two required bands on AWS... Which is the band T-mobile USA uses for 3g and "4g". If your carrier uses AWS for 3g, it won't work on their network either.

No this is not possible. Turkcell is using 2100 Hz.
I have bought 3 phones from amazon.de site. The other 2 phones are working.
I have to get my settings set properly, to make sure its a faulty product, so that I can return it.
There are menu options like HSPA revision, GCF, bank selection, service domain, acquisiton order etc..
Where can I find what they have to be?

In that case, just go back to that service menu, debug screen - phone control - network control - band selection. Make sure this is selected to automatic. You can make sure all available bands for this phone are selected on in combi bands. If they're all selected on, then it sounds like it could be a hardware issue.
EDIT to add: OR it could be a modem issue. Maybe try flashing different modems?

At work we have a Vodafone SureSignal as the normal mobile reception is rubbish. SureSignal has been working fine for some months with all phones including my HD2, but the box packed up last week. We have been sent a new box which was not picking up my handset. I phoned Vodafone and was advised to change the band selection from 'Auto' to 'UMTS(2100+900)'. Sure enough my phone connected to the device.
However, I understood that that would mean it would only connect where there is a 3G signal, so I tried selecting GSM(900+1800)+UMTS(2100+900) and that worked. But now that doesn't work and I can only connect to the SureSignal by selecting UMTS band only.
Does this mean anything to anyone, and can anyone advise whether there is anything I can do that means I don't have to keep changing the band selection on my phone manually every time I enter / leave the office? Is the box not doing something which is why my phone isn't picking up the 3G signal (I have no problem with 3G elsewhere)?
Thanks.
Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.
So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...
Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.
So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).
So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?
-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?
-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.
Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.
If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!
Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!
U have the international note. Doesn't have late chip in it. But ur note has better CPU then the att note. The international note CPU is not comparable with att lte chipset that's y Samsung use 2different CPU. Yes u should be able to get 3g. Reset your apn. And search around. To find the code to reset your apn. I forgot. Its something like *2260*
I had an international first, had to rest everything to get data. But after few days. I return it cos I prefer to have lte speed more then CPU speed. And I found out the u can just over clock att note to 1.85 instead of stock 1.5. So now I am very happy with my att note.

Hmm I'm not sure if this method works with the International Note but it's worth a try. You need to get into ServiceMode. On your phone dialer keypad type *#2263# and choose 2 WCDMA Band Preference and select (6) WCDMA all.
Reply with your findings.

Thanks for the tip, but all I get is an error: "Connection problem or invalid MMI code."
:\
Maybe the issue is your kernal and/or radio? Isn't the Tegrak kernal Korean? Most likely your radio is also. That is probably your issue. The way I see it you have 3 choices: Live with it, Sell it and buy an I717 variant, Take the risk and at least flash the ATT Gingerbread radio.

Do all your entries match these? Write down your current ones before changing or take screen shots. You must use the menu key and save changes. Also make sure that is the APN checked after rebooting.

he doesn't have the international note(n7000) he has the South Korea Note - the SHV-E160S (he says it in OP), which it has the same processor as ours but some minor diferences in other things.
To the OP, why do you have a korean Note when from your avatar you're in the US?, I'm sure there's your problem, that note is set to use bands in korea and not in US, so the data is going to be crap, and for you to attempt to swap out the antenna is risking braking the phone because you run a chance after swapping it, not working and not having a working phone anymore.

I matched the APN settings of my fiancee's LTE Note first, and that did not work... It's pretty much exactly what you have posted. However, there are a couple things of note (bad pun, sorry). I do not have a 'APN enable/disable' or 'Bearer' field... However, everything else is set the same.

I have a Korean Note because I was living in Korea for a while, and I just got back to the US last week.
As in my OP, I found that the LTE bands are different; however, I can't even get on any other data networks other than GPRS. I've tried some APNs for HSPA+, and the results are the same.
Swapping the antennas shouldn't be THAT big of a deal if I had to... I'm pretty mechanically inclined. Obviously, I need to know if it would provide the intended results or not first.

Hi folks,
I've got an unlocked HTC One Max which I bought SIM free from Amazon UK. I'm using Three as my network provider in the UK and they've begun rolling out 4G to Glasgow where I live. One of my colleagues is also on Three with a Samsung Galaxy S4 and he started picking up a 4G signal this morning in the office whereas I'm still only seeing 3G. We had a poke around on our respective phones and in the Mobile Network Settings under Network Mode he's got more options than I do, including one for LTE. I've only got two options: WCDMA only and GSM/WCDMA auto. Without being able to select an LTE option in here I don't see how I'm ever going to pick up a 4G signal. Does anyone know why I'm seeing no LTE option in here and how I go about sorting that?
Okay, so I did a live chat with an HTC rep who confirmed that if there's not LTE option available in the settings then I've got the 3G only variant of the handset. I've no idea why HTC would even sell a 3G variant in the UK as it makes no sense at all, but I looked on Amazon and they only sell a single variant of the phone (which is definitely the one I bought) and curiously the listing for it doesn't clarify either way which network protocols it supports. I even tried Googling the product number (99HWN005-00) but I can't find any solid information about which version of the phone that represents. I'm hoping here that it's just a mistake and I should've been sent the proper 4G variant but it's impossible to say for sure when the Amazon listing gives no info at all about what they think they're actually selling. Either way I'll still be trying to get Amazon to take some amount of responsibility here because I think I made a fair assumption that I'd be buying the 'proper' version of the phone from them; especially as there's nothing on their site to tell me otherwise. I suppose it'll be down to how seriously Amazon take customer service as to how far I get with them. God damn it!
Grrrr. So I did another live chat with HTC to try and find out more about which models they sell in the UK. The Amazon listing has a model number and I was hoping HTC would tell me that's the model number for the LTE variant so I could go back to Amazon to say they'd mis-sold me the wrong version. This time though I got a different story; the HTC rep told me my handset is definitely LTE capable and what options you see for networking are tied to what the SIM card is capable of. His assertion was that Three had given me a 3G only SIM card and getting that sorted would fix it.
However, I swapped SIM card with my colleague who's getting a 4G signal from Three and it made no difference on my handset; I still only got the same 3G network options and, of course, only got a 3G signal. It also occurs to me that I checked with another colleague this morning who's got an HTC One but only on a 3G contract with O2 and he's already got the LTE network options (although he only ever gets a 3G signal of course).
So, yeah, this second call to HTC was a load of nonsense. Excellent. Back for a third time I go...

Perhaps the variant you purchased does not support the lte bands that your carrier is using. That's usually the difference between the variants....radio support.

Even if that was the case I would still need to see the option in the settings to turn on LTE; I don't even have that option so regardless what bands my carrier is using my phone wouldn't pick up a 4G signal of any kind.
I've basically somehow ended up with a 3G only variant of the phone which frankly they shouldn't even be selling because there's no point. I might ping HTC again with a more direct question but they don't seem to be able to tell me what I've got so it's more likely I'll just go back to Amazon and see what they have to say about it.
Also I did a quick check and Three are using the 800 MHz band which the 4G version of the HTC One definitely supports.
Okay, so, I sort of got it fixed but it's a really stupid situation. There's a key code to get into a hidden setting menu on Android (*#*#4636#*#*) which bypasses the normal options and allows you to force the network mode to any of the ones Android itself supports; so it's got all sorts of weird **** like EVDO and whatever in there. I went in there and forced on 'LTE only' mode and now I can pick up 4G if I stand in certain parts of the office. I've put it to 'GSM/WCDMA/LTE auto' and it should now go up to 4G whenever it gets a strong enough signal and work as it should. Why I've had to do that hack to get it working, and why the normal user level UI doesn't expose the LTE related options, is a ****ing mystery though. With KitKat rolling out that might might sort it but I shouldn't need an OS update to expose functionality the hardware's already capable of. It's really ****ing stupid all in and not doing HTC's rep any favours with me as I'll probably have to repeat the same stupid hack every time I reboot the phone.
Hello All,
I am hoping that someone can help me out.
I purchased 6 Samsung Galaxy S3 unlocked phones. I put SIM chips in each, all from the same provider and all with the same service plan. 3 of the phones everything is working great including fast Internet. The other 3 phones have extremely slow Internet. I did a bit of research and noticed that the phones that are slow display EDGE in Mobile network type. The phones that are fast display HSDPA:9 . Could this difference be the cause of the data speed problem? Can anything be done to fix it?
My apologizes if this is being posted in the wrong forum.
Thanks

In your way, EDGE means slow, HSDPA fast, HSDPA offers speeds up to 21mbps (if your carrier supports it) and EDGE up to 0.5 mbps or so.
Now, if your 3 other phones don't connect to HSDPA (3G) then it's disabled in settings or signal is low or the chip is messed up.
So by checking if everything is good go to settings, under first tab (connections) go to More networks > Mobile networks and make sure that under network mode WCDMA/GSM is checked, notice that WCDMA is HSDPA.
If still not getting faster speeds try to check if WCDMA only option works, if not, eh, bad chip.

Thanks for the reply.
I activated the WCDMA/GSM. As soon as I did the icon status(?)displayed on the top of the phone turned to a circle with a line through it. About 3 minutes later the status changed to an E with bars next to it. The Status/Mobile network type still says EDGE.
When I try to connect to a site it is slow. Does this mean the device is still getting the 2G signal? Could all 3 phones have a bad chip?
Thanks.
that is true

Do all of the phones have the same baseband? Check in settings, about.
Just to make sure the modem is the same.
I just check 2 of the phones (they are all not with me now)
The baseband of one of the good (fast) ones is: I747UCDMG2
and on one of the slow data phones is: I747MVLUEMK5
What does this mean, that they are not the same?

Both are i747 version which is not international version, maybe Korean or something like that, try using only WCDMA this is constant 3G, and see if it works, if not, flash the latest software from sam mobile via Odin, but watch out you download for i747, not i9300 etc. There are many S3 variants.
I tried using only WCDMA with no success.
Do you have instructions of how to locate and flash the latest software? Also I know the phone is currently unlocked would this change that?
Thanks so much.

If it is unlocked, it shouldn't change that.
And note if changing software doesn't help then the chip might be damaged.
For software, go to www.sammobile.com and register, then go to browse firmware and select android/galaxy s3 bla bla.. until you get to country, there select your country, or go to top and select 'top 10 latest' and choose one that is different from yours.
You can know of it is different by the baseband name letters for etc 'XXUGNG3'.
Then download the software you want (it may take a while) and download Odin v3.09 (just type that in google you'll fond ot) and Samsung USB Drivers (also found on google easily).
Install usb drivers, reboot, open Odin, extract downloaded firmware, go to odin and select AP and then navigate to extracted zip and select you software.
Then put your phone in download mode: hold vol down+power+home and then vol up for continue when you see the picture, connect your phone and flash.
Also, please, about that, read here on xda and see tutorials on youtube, this has been answered multiple time and.i am one of rare users that will thoroughly help in answered questions.
I followed the instructions and flashed the phone. It did not help.
Any other ideas? One of the phones we got was brand new! I can't imagine there is a faulty chip in 3 out of 6 phones?
I am frustrated.

Are they unlocked? Of they are try another carrier, or try somewhere where the signal is at it's best reception.
If these simple methods don't work just get it analyzed in the service center, i doubt it can be software problem because you tried with another rom, also, when you'll try maybe changing carrier or going around town to see if it works, and it doesn't, then it is hardware problem, unfortunately.
Thank for all your help.
Nothing seemed to work.
I did try another carrier and it did not work.
I just can't imagine that 3 out of 6 phones have the same problem and 1 of them is new.
Could it be that the 3/4 G only works in the USA and not in foreign countries?
My phone is a T-Mobile branded DE2118; I have noticed this app in those secret launchers(I use Activity Launcher); I don't know Chinese at all and also when I set something I lose my signal for 5-10 minutes.
Regardless, this phone has the SD480 in it and apparently with the x51 modem it should have support for mmWave.
Is there any way to change/modify the bands at all within this app/program? Has anyone actually been successful with it at all?
I have had success using com.oneplus.engmode for LTE band selection, making sure I set the signal to lte_only in the *#*#4636#*#* phone menu
Well, there's an issue; *#*#4636#*#* doesn't work for me......
I wonder if it was caused from when I bricked my phone a month ago?
I don't know, but here is a video of the process on mine
