[Q] Signal Issues ... Strange one - Galaxy S III Q&A, Help & Troubleshooting

Hello all
I have a non rooted and completely standard S3 with I9300XXEMG4 baseband .
I am however using the zerolemon 7000mh battery.
Now since the last update to MG4 my signal seems worse.
If I have my phone lying on the table it'll get 3 bars signal strength and "G" data .... Im not in a fast data area.
So my phone sits with 2 or 3 bars signal ..etc 95 dBm and 9 asu .
Without moving the phone if I then plug in the charger either USB or the Wall socket within a few seconds my phone signal disappears all together ..... it goes to Unknown network and out of service ect just showing the circle with the line through it meaning "no service".
Unplug the charger and within a few seconds or a minute my signal returns.
I know this sounds strange but im going to try and get someone to video it so I can upload it .
Anyone know whats going on here or how to sort it other than smashing up the phone and claiming on insurance ??

Its not identical ..... I have supplied more info than before and never got much interest before apart from "test with original battery" which I already did or wouldn't have bothered with the question.
I also don't recall mentioning the issue when plugging in a charger in the "other" post either ????
The "other " post was 3 WEEKS AGO ..... I don't think you can call it spamming but if it makes you feel better then fine .
However if you feel the need or it makes you feel better just ban me or report me .
Oh and thanks for your help

[Q] Freezing/loosing signal during calls

Evening guys
I rooted my S2 when i first got it and haven't really touched it since. It's an O2 handset running Baseband version I900XXKE4 and Build Number XWKE7.
My isue is that i'm struggling to make calls on it, pretty much every call i make now the phone call drops out and the phone freezes up for around 20 seconds. Sometimes the persons voice on the other end will stutter like crazy like a stuck record and the bar at the top will turn green.
Has anyone else experienced this? I haven't searched the forum yet so apologies if there is a thread about this...
I'm thinking of flashing it with the latest firmware to see if this remedies the issue, could someone give me a quick nod to the latest firmware for a UK phone? I will head on over to the development forum now but i haven't looked for a while so am hopelessly out of date with it all
Thanks for your help guys and gals

Thanks mate, should i be looking for XWKG7 in the thread ROM + Guide?
http://forum.xda-developers.com/showthread.php?t=1075278
I can't seem to find it in there? Only XXKG6 which is a frankenstein firmware...
apologies for bumping this but my phone is virtually unusable I cannot make or receive calls with it, every time i try the signal drops out completely like it's in airplane mode (which it is not)
Anyone had this problem?

Help: Strange poor signal

My i9100 has very very poor signal....i try a lot of modems (kh3, nelp3, etc) and roms (GB, ICS, JB) with no lucky. Is strange but when I take my phone from the bottom with hand (where the antenna is located), the signal immediately lost, and when i take phone from the top and put it upside down, i have one or two bars of signal.....I have seen this page: http://www.mobilerdx.com/2012/05/samsung-galaxy-i9100-s2-no-service.html# but I guess that is not my case because I have a little signal. What can I do??? Is a hardware issue??? Please help and sorry for my bad English....

Did you give the modems time to settle? They're like roms in that you have to give them a few battery cycles to see the difference between them.
Also, what rom are you on? You can refer to the thread in my sig for the info needed to get the best answers..
Try this network signal speed booster
Hit thanks if ive helped you

Here is the [REF] Galaxy S 2 Shipped Modem Collection
as what the guy way above me said, kernels are like ROMS, usually just flashing and then using the same modem for 3-5 days should tell you how well it performs in your country and with you Mobile Network operator. Please remember that it takes around 2-3 days for a Modem to "settle" and achieve optimum performance, so don't judge how good a Modem is straight after flashing. That's where a lot of people fail when asserting battery drain.
but you can test your signal strength here: Network Signal Info
i hope this will help you!
cheers
Thank you guys for your replies but my problem is more serious. No matters which rom or modem i am, the phone signal is practically 0 all the time, only when i take my phone from top and turn the phone and extend my harm, i can take a little signal, or when i am very close to operators antenna i cant take decent signal.... the phone is useless now to make and receive calls....i think maybe is a hardware problem, but the little signal makes my think is software, i dont know......i´m crasy now....

Your problem could be either way.
Try this app and tell me if your problem is resolved: https://play.google.com/store/apps/details?id=com.sibbor.getril&hl=en
Root is needed to run the app
Swyped from my Samsung Galaxy SII
It seems to be a hardware problem. Insert your SIM to other phone and check the signal.
SOLVED.......I do it!!!!
It seems that my problem was the white cable connector on top, or something like that, because when I put a small wire from the white cable (with a small cut in the coverage) to the external antenna input, the signal comes back like a charm!!!. I leave a picture of the mod in case anyone needs to do the same and I hope this helps. Thank you guys for your answers, and again sorry for my bad English.....Jokesy, i will tray anyway your recommendation to find any error with the RIL, thank you....:good:

[Q] Charging Flex Cable Problem

Hi, I have the Galaxy Note i717 and had to replace my charging port as it had stopped charging reliably. I bought one of the many on ebay for around 8 bucks. I proceeded to put it in when I received it but to my dismay I no longer could get service at all, just wifi. So just to verify it was nothing I broke I put the old pcb back in and service returned. At that time I believed it was just a defective unit, so second try at it same thing no service old one works fine. Is this a problem anyone has ran into before? Any help I would appreciate.

It is quite possible that either your new port is the wrong part, or is damaged.
The port wiring is different between models ...I.E. SGH-I717, N7000, and other note models.
Even the charge cables are different part numbers between models, but visually look identical.
It just sounds like the port wiring is different to me ..
I suggest getting the port directly from samsung...even though it will cost a bit more.
At least then you have a fall back if the port won't function.
Or perhaps have the port repaired by Samsung directly ....
I'm sorry I can't offer more help .g

Well both pcb boards that they sent me have the same markings as the one I removed. They also say on them SGH_I717_SUB_REV1.0_1107
So I do believe it to be the correct part. Just to clarify the new boards do charge the phone just cellular service stops. Maybe by some crazy luck I got two faulty boards. I wasn't sure they were going to send me a replacement so I ordered from another company as well so I guess I will have to see if that one works,
Interesting ....
The part seems okay ...
And the odds of two bad ports in a row is remote at best ....
Some time ago I saw a thread about an extra wire that traveled down from the antenna to the charging port....
And users were reporting that this very small wire was being damaged or missed when the port was serviced.
I've never seen this wire or connection ......but I figured I'd bring it up ..
Try a general search on the topic ...and see if it yields a result.....
I just remember it being a big deal ....g
Just wanted to update the post in case this happens to anyone else. After getting the free replacement for the first part I believed to be defective I also ordered from another company as it took more than a month for my replacement, so I believed them to had stood me up. Well the one from the other company arrived today, and worked. Maybe the others were for different networks or something. I don't know if that is possible Rogers vs ATT frequencies and what not but it worked and all is well.

I am having issues as well...
My phone has a Rev1.0_1107 part, and I cannot charge unless I play with the cable, so i decided to replace this port.
1st was from China (ebay) and received no signal, only wifi. Rev1.0_1107
2nd was a replacement from the same company, same issue. Rev1.0_1107
3rd was from a place in CA (ebay) and is Rev2.0_1206 and same issues.
I can put my original part in there, and I get signal just fine... anybody have any ideas on this matter? It's frustrating to have to keep battery swapping and would like to get this fixed.

Noted... thanks. I have searched them out and they only appear to have the cable for the N7000. Can anyone else recommend a place to buy these from?
Just noticed that when it's near my window, I get 1 bar of service... So it's like my signal strength is uber weak. I have a microcell in my home, and it is functioning properly (other ATT phones are connecting just fine) and works again as soon I put the original cable back.
Hi,I have a samsung Note N7000.
I'm have a similar issue,start with high power charging issue every 5seconds.I bought a replacement from ebay company in New Jerse it fixed that problem.but it created a problem when I make a call the other end can not hear me.I email the company and they sent #2 replacement.after
the charging port board was installed now I dont have any signal for service.the pcb# N7000/i9220_sub_Rev1.0.
I'm going try different company.what should I be looking for?I'm wasting too much time on this.

Sorry to bring up an old thread but I wanted to bring this to others attention. What Gregsarg said about a white wire running down from the antenna is correct, or at least it is on an i717. It runs down from the right hand side of the board, behind where the flex board connects and onto the little round connector on the flex board, it's probably that that's been missed off of some phones as would be noticed by only getting 1 bar of signal! I've also noticed that the UK version of the note only has 4 brass connectors on the flex board 2 for the antenna and 2 for the speaker whereas the i717 has 5, 3 for the antenna and 2 for the speaker. I'm not sure what the difference is between a white or black i717 to be honest, i'd have thought it would only be the outer casing that had changed, I can't see them changing parts too, that just sounds stupid!
Anyway, the reason I'm posting is not just because of the above, it's because i'm in the middle of fixing an i717 for someone and was searching to see if a N7000 part would fit and although it looks as though it would I'm not willing to test that theory! I will say though that the missing brass connector is also connected to brass connector 2 on the Ariel/speaker module but on the flex board that connector also has a resistor above it which would likely cause an issue!
The part that i'm ordering is from a company in the UK but is a Rev 2.0 board and not the rev 1.0 that is in it already so i'm hoping that's not an issue else i'm gonna have to buy from China which is cheaper but will likely take an age to get here and the customer wants it done ASAP so what they want they get! I will update this thread once i've fitted the part and got it running along with a link to where I got it from.

When getting the part, Revision usually does matter. Also the serial number under the revision number (Usually starting with DRC or DRG) can also matter. Getting the identical one is usually the best bet (albeit not the easiest considering people on ebay use stock images and don't show you the ACTUAL part you're getting.)

I got the new part this morning, it was a REV 2.0 board and after putting it all back together including the white/grey ariel wire I can report that it's working perfectly, as good a signal as it had before and is now charging properly. The link to the UK based seller is here for anyone interested that needs a replacement in the UK - http://www.ebay.co.uk/itm/300819833823?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 The part is £19.99 with no P&P and arrived in 1 day. Just in case the link doesn't work then the name of the supplier is gravedigga1.
EDIT:- I heard back from my customer today who has reported having problems with wifi, signal and loudspeaker! Therefore the Rev 2.0 part won't act as a decent replacement for the Rev 1.0 unfortunately. I wasn't able to fully test as the customer didn't leave his sim card in and he uses 1 of those weird networks which I don't have a sim for. I have managed to source another UK supplier on ebay for an even cheaper price of £12 and they verified that it is a Rev 1.0 board they have in stock and have put 1 aside for me. Once I know that one works for definite i'll report back again just to update the thread but this time the customer is bringing the phone when the new part is here so it can be tested fully before it goes back to him!
I just find it strange that even though the Rev 2.0 is exactly the same in every way as the Rev 1.0 board that it has these issues although i've not heard of the loudspeaker problem before so I think there's a fault with it anyway.
Yeah these notes are getting really dodgy in their old age. We've decided to basically not fix abutting except the screens anymore because getting the right parts is a nightmare.

This may be a little off key here and if I'm in the wrong thread I apologize but...
I have the i717, bought the charging port off of eBay and replaced it. After plugging in the phone the touch keys at the bottom lit up like I was in business. After allowing the phone to "charge" for about 2 hours, the touch keys were the only thing to work and light up on the phone. I could press the lock key on the side and the touch keys would come off and on like it was on the lock screen but the screen was black. Has anyone encountered this before? If so, please help!
Thank you
Btw, it seemed like the phone was charged/charging bc those touch keys were on...

Pease Help..i717..charge port
Hello ,
My name is Russ and I have a Samsung Galaxy Note SGH-i717 ( AT&T ) which I love . About two months ago the charge port quit working , so I ordered one from Ebay ( Flex cable , Mic/USB board ) , installed it and my signal was weak after installing it so I reinstalled the original board and it went back to full power . I thought it was a bad board , so they sent me another , I installed board #2 and the speaker on the back had no sound , put my board back in and the speaker went back working . So I had the supplier send me another board #3 . I got it installed , and the Mic wouldn't pick up , I put my board back in everything goes back to normal . So I thought it might be the supplier , so I tried a different supplier , same thing . In total I have tried three different suppliers and I lost count on how many boards I have installed .. Every time I can reinstall the original board and it will stop whatever it's doing wrong . My board Number is SGH_I717_SUB_REV1.0_1107 , DRBL12IN BF , 69 . I am at a lost , I don't know if there's something I'm doing wrong . Thank You for your time ib6469 ( Russ )

Please let me know if anyone has had any luck finding a board that works... i am in the exact same boat... email me at bnanda0827 at yahoo.com

Droid DNA connection issues.

Hi guys,
I have had my droid DNA for about 3 weeks now and it seems like my phone has connection issues. Its not a black and white issue or else i would returned it a while back. So i am here asking if anyone has or thinks they may have the same issue.
Here is what i have noticed.
Ok so my wifi at home is good but not every spot is good. On my old phone's the wifi meter on the bar would go up and down telling me that the signal is low or high or whatever but on the DNA i have noticed that it always shows full even if its not fully connected. What i mean by fully connected is that it shows the bar being at full but say i open a news app it takes forever to load the content ( aka its waiting for the phone to establish a connection ) or sometimes it actually tells me no connection at all ???????
I have had an android phone for over 4 years and i have apps developed so im not a newbie at this but im having a hard time putting my finder on the issue to see if it is an issue or just the way that the DNA functions.
If you guys have experienced anything similar please share so me and the rest of us can conclude if this is an actual issue ( aka return the phone and get a new one ) or just the phone characteristics

[Q] Have weak signal after repairing SOLVED

hello to comunity,
i have the samsung galaxy s 2 gt-u9100 mobile phone and everything was perfect untill i opened the phone, the phone has problem at the back housing so i ordered a new one and replaced it, i made everything with caution and slowly. while i changed the back housing i opened the phone and everything was good untill i saw that there was no signal. i did it 2g and i see that there is onlu on raw ar the signal and sometimes none.
i opened the phone again and checked everything but saw nothing wrong. as i searched i saw that the GSM is this part and the cable that connects the antenna is this one . both of them are perfect.
i lost all my day trying with that , at start i had SlimRom 2 then i put the stock one via Odin but it didnt boot, stocked in the boot image (didnt wanted to search why ) so i flashed kernel again and then NeatRom, still no signal and then i went back to SlimRom. but the problem as i saw is not from the rom .
if anyone knows about that thing and tell me what to do i would be gladfull .
That bit is the antenna c/w speaker.There is a thread related to this about usb replacement.People mention about similar problems when they remove the antenna cable.
Heres a pic of spares I have,and look at the gold contacts on the antenna,as they need to be in good contact with the ones on the usb board.Maybe its that,or maybe new antenna is faulty.Try your old one in to eliminate that though.It could even be the antenna cable.
The thread is by someone whos name is Dugud,or similar

thanks a lot for your reply my friend, my problem is not with the usb think i thing, it must be with the cable or i dunno. i had verry good signal and everything was working, now just the signal got verry low.
exept from buying repair part you say there is no fix right?

maybe take it to a shop with someone who knows what they are doing. I just had to do this with mine, I considered trying to get parts cheap and diy then I considered how much time and stress it could cause me = not worth it. It cost me £25 to have usb replaced, second thing I checked was the signal as I see many having problems with this - outcome is my phone is working sweet again and it only took a couple of hours of my time :cyclops:
Best of luck
Did you read that thread?.I seen a post on here once where someone said they removed that white antenna cable,then refitted it,and lost signal.Then they bought a new cable,which solved the problem.
Also, you dont know the condition of the part you changed,and theoretically you are meant to use anti static wristband and mat when your touching sensitive electronic components......lol
