no gsm signal no gps signal

i recently lost my battery cover and while waiting for the replacement to arrive i noticed one day that i had no calls all day long which was strange so looking closer i noticed the ! near the antenna icon and also no gps signal at all either.upon closer inspection of every thing i notice that the antenna on the back of the phone was torn.see pic red circle shows where the tear was.so i clean it up and whip out the soldering iron and solder it back together,but it still wont work.is the antenna that sensitive that it wont work even after being soldered back together.do you think replacing the antenna with a new will fix the problem?

when you soldered, you could've damaged it further, even a little overheating can ruin it.
Also, the picture doesn't show any tearing, the places you circled is a point to release the casing in that area.

this is far fetched, but my profession and hobbies bases my know how on situations like this.
when a antenna is placed in a device like this the technicians adjust it to be resonant to specific freq. adding or removing length (like you did when you soldered) adds length to it (the antenna usually in a cell phone is brass or copper) im sure the solder you used is 60/40. so by adding more metal and changing the metals, the antenna is now resonant on diffrent freq's.
instead of giving a lecture on antenna resonation to exlplain here is a link
And like the other member said you might have overheated the board.
So hope this helped. And sorry if it didnt

the pic is not of my phone,just a pic for reference to the area.i used silver bearing solder 62/36/2.the antenna was removed from the phone before it was soldered.i guess ill wait for a replacement to arrive.right now the phone is junk with out a signal.

Well since you have a new phone in the mail nevermind, unless you want to share pics and go into specific detail of EVERYTHING you did. And maybee we can help.

Have you taken that plastic housing with the antenna off?
Or has ait had a knock?
I ask because there are small plastic lugs around that housing to keep it firmly in place. If any one of those is not fully engaged the connection with the aerials is lost and you get no signal. Of course a crack that allows enough bending will also cause the contacts to be lost.
To elaborate Look at the second picture here with the black aerial housing removed:
https://fjallfoss.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=812152&native_or_pdf=pdf
You will see the gold coloured contacts for the aerial. Any maladjustment or lugs not engaged or a crack can cause these to loose contact with the board. If the plastic is cracked in a minor way, I'm sure you can work out a way to re-establish the contacts.

Does anyone know where to buy replacement Aerials? Mine kinda detatched itself from the plastic! :S
Please PM or message me if you do know where I can buy one or if anyone has a dead phone that they wouldn't mind selling for spares.

How to Boost Signal

Is there any APP to Boost signal
MY T-Mobile HD2 drops signal on 1700 AWS WIND Network in Canada
is there and mod or tweak I can try
is there any ROM which is known better for bentter network reception..
please reply

Do you have WM6.5 or do you have android installed on your HD2? You should have posted this in one of the general forums (HD2 WM6.5 or Android general) so I would know and could provide the app to do this.

I have NAND Android and I am currently running on HyperDroid-GBX-v12.
Please advise if there is any way to get better signal or any ROM which is known for better signal strength

Try a few different radios. You flash them just like a Windows Mobile ROM. Flashing a new radio will not erase your Android ROM or CWM or anytthing else, just replaces the radio.

I have a sticker like this just over the antenna, it gave me 1 bar more in a place where I had only 1-2 i reached 2-3 bars in Android.

I want to think it works, it was less than $1usd, so it won't hurt and it is not visible.

You will keep running into problems. Switch from WIND to a better network. If you don't need Data. Chat-r is brilliant. I Just did the same a week ago. Life is much easier.

Lol, those stickers don't do anything amigo. Ask yourself "how does a piece of gold painted plastic boost my phone's ability to receive or transmit a signal?"
Placebo effect at best.

The signal levels in this video are my exactly experience.
It is cooper I think help to "concentrate" more signal to the antenna (in/out).
Probably just works with the GSM(2G) signal -which I always use-
I have been using it for +7 years now (total cost < $3usd).
edit: If anyone plan to buy it.. don't spend more than $1. there are some crazy prices out there.

OK did a 5 min test w/o and W the sticker on my HD2 running on 2G t-mobile USA in the exactly same place.
W/o the sticker:
-77dbm 18asu
With the sticker:
-73dbm 20asu
Again only 2G (3G might get worst) and don't pay more than $1

the technical idea behind those stickers is real. the sticker itself is a thin copper foil. When hit by EM radiation it will provide a greater surface contact and will radiate the EM energy on it's own. It's a bit complicated, i cannot explain it in english.
However think of it like when you have a piece of metal placed near a magnet. Even if the piece of metal is not magnetic by itself it can become magnetized and will attract other pieces of metal by its own even if the original magnet was removed.

Good to hear that I'm not living a lie having those stickers. I knew that that weird design , which looks like aliens did it, has some engineering on it.
By the way, i have not try to improve my signal via software bc in my simple mind to do something that works you need to fool the phone to think it has always low signal, therefore forcing it to "radiate" more and improve my reception.
I have the phone in my pocket.. and I don't want a free vasectomy.

The functionality is "induced electromagenticity". The radio signal crosses the thin copper on sticker and induces current. This current reproduces voltage which beams signal again. Something like a relay functionality. ...for poor man

Where exactly do you stick it? Under the battery?

No, it has to be close to the antenna so I placed in the plastic area where the "void" screw is and the sticker will cover a little of the sim, the hd2 antenna is around there. I didn't want to stick it(bc it interferes with the sim, etc) so I carefully placed and put some tape in the edges of the sticker so it wont move.
All this is under the metal battery door.

Many thanks, it's worth a try!

I see only comments about the sticker thing. Not about the flash. I really doubt the signal will be any better with the *.apk provided in above post. RIL tweaks seem to be the better choice because it depends very much on where you live (at least so it seems from other posts).

[Q] radio/antenna quality?

It's probably too early to answer this question, so maybe this thread will be a placeholder. But does anyone have any experience using the One where reception is weak? Are the tiny plastic windows enough for the antenna to work? how is signal strength in general?
Thanks!

People who have been to HTC events have tested this. I will try when I go to the event in newcastle on thursday. They said they couldnt get it to drop a bar.

It does not use the tiny plastic antennas, it uses the top and bottom pieces of metal.

the radio/atenna quality is excellent, tried it with calls/gps/wifi. locks fast with wifi and gps and calls and loud and clear

Any other N950N owners suddenly have terrible cell signal? Look at this...

So a few of you have seen me mention that my cell signal suddenly became awful after a few days of use, and at first I thought it might be related to flashing CSCs or a 950F ROM but ruled that out since Odining back to full stock didn't have any effect.
I became convinced that something must be loose with the internal antenna wires, and also observed that the signal seemed to be a little better on hot days and a little worse on cold days.
Well after watching a couple YouTube videos of how to pull the back off this thing I fired up the microwave oven with a rice-filled sock for heat and..... it didn't help. BUT! a hair dryer worked wonders, and very quickly. I only had to heat up a small section and use a little blue plastic prying tool in my ifixit kit to really easily get the back of the phone off.
Next, I pulled the plastic pieces off the circuit boards to get to the antenna connectors, fully expecting something to be loose. Sadly I was mistaken. both wires ends were securely snapped down, but I disconnected and reconnected "just in case". I decided to do a real battery pull discharge while I was in here since it couldn't hurt.
-------
Not to be foiled, I decided to fire the phone up naked and just fiddle with the connectors to see if somehow they were still involved.
I was right - sort of. If I apply pressure in certain angles on this connector, the LTE strength will go up to about -82 dBa from bouncing between -98 to -125 dBa - and as a reference point my Note 5 in the same position sits at -82 or -83 dBa
Now I just need to decide on the best way to fix it, I think it might just be bad solder joints on the socket on the circuit board since it appears to be temperature-dependent (on hot days everything expands to make slightly better connections, cold days the parts contract and the connection gap becomes worse). Any other 950N owners experienced this?

Also does anyone know if those antenna connector sockets are surface mount, or if they go through the board completely?

I commend you for doing what you are doing. Kudo's as they as say here in America.
Just out of interest, I am aware that Samsung doesn't support foreign devices for warranty. But would they support a foreign device for out of warranty work?

My best guess is that they might not because they would claim that they don't have the parts or training to service a foreign variant. On the plus side, it's nice to see that the internal layout is identical to the Snapdragon version so I didn't have to do any guess work.

No experience myself but I have seen online numerous times that they will not even if you pay. Lots of manufacturer's do this, it not just with phones. Like Seiko watches for example, you purchase a Seiko say for the Japanese market, Seiko USA will not touch it.

Yeah it's unfortunate since you know they have access to the schematics, repair data etc but refuse to take your money.
As far as my phone goes, I tried reflowing the solder on that antenna connector but it didn't seem to make any difference, and now I can't get the signal to improve back to normal at all (even applying pressure as I did originally).
Funny thing is that my 3G HSPA and HSPA+ (that T-Mobile calls 4g) signals are just fine. If I turn off LTE, it drops to "4G" and aside from being slower than functioning LTE everything works fine. My guess is either something is faulty with that bottom circuit board, LTE modem which is on the main circuit board, or the LTE radio amplifier chip (also on the main circuit board). Once I can get a new replacement USB board I'll swap it out and see if that helps. If not, I'm kind of SOL because if it's something on the main board I would likely just need to get a new phone (can't imagine how expensive a 256gb internal storage board would be brand new but for the price I would feel safer just buying an entire phone).
Really wish there was some way to get Samsung Korea to repair it for me but I don't speak Korean well enough to have that kind of discussion yet, and who knows if they would even agree to it.

I hear but unfortunately sometimes they really don't have access to repair info & techs that are trained for non domestic market models. Samsung USA may actually not have easy access to Samsung Korea info & parts although I'm sure someone high up on the ladder could get it.
I used to work in electronic depot repair. One of our customers was Sony VAIO, we were one of their authorized repair centers. Not easy to get that kind of relationship as Sony is very secretive, well all OEMs are very protective about internal engineering info. We could get most info for all their laptops & worked with their engineering team. However when we started working on Sony Playstations, Sony Entertainment would not give us the time of day even though we were an authorized provider for Sony VAIO.
I know the case is a bit different but big corporations have regions or different divisions that won't or can not easily work with each other other than on a corporate level even though they are all part of the same parent company.
I'm sure there are lots of people at Samsung Korea that speak english. Whether or not they will help you or if you can get in contact with the right people is the issue. Worth a try. I'm sure parts will be available on ebay someday but probably not for a while.

Very good points. I'm even more sure it is just something faulty with that board. Heated it up for a few minutes with a blow dryer before reassembling the phone again and now my LTE signal is just stable low instead of jumping between low and unusable. Also comparing it to the one from ifixit's USA model Note 8 teardown, they revised it a few days after mine was made, possibly to address whatever caused mine to go bad after a few days of use. The only change I can see is the placement of two chips on the antenna connector side.
Since I can't find parts yet I may just keep trying to fix this one but it's good to know that the usb boards are dirt cheap, for other Samsung models it looks like they go for $5 to $10 on eBay new. Of course if the problem is a break in one of the circuits inside the pcb i can't really fix that (assuming I could even see it, everything on this board is so tiny I need a magnifying glass to work on it).

Yeah, it's incredible how small they are able to make things these days. I can relate as I have worked on stuff that small also.
Oh so it it looks like they revised the board? Maybe they just added better filtering? Hopefully it'll be available soon. It could very well be a bad solder joint or defective PCB. The PCB is so thin & can easily get damage by flexing. And all that crap lead free solder they use these days.
I wonder if the parts they sell on ebay are OEM parts? Whatever, as long as they work. They sure do look OEM though. On my N5 the USB port stopped working. It doesn't have any notice physical damage but it doesn't work. Sometimes if I plug in a cable a gear vr screen will pop up. Won't ever fast charge, sometimes it will cahrge normal, & can't transfer data.
I bought a replacement USB port for $5 on ebay along with a replacement back cover in case I broke it. But the damn board also has the front touch screen buttons by the home button. So to install I basically have to disassemble the entire phone, front screen and all. Ah I don't feel like doing all that. Maybe someday but for what, I have this N8 now.

Oddly my Note 5 still works just fine... The main reason I wanted to upgrade is that the battery life is definitely not what it used to be.
Fortunately with the Note 8 most of the goodies are accessible once you remove the pain in the butt rear glass but i figured out that a hair dryer, suction cup and thin plastic pry tool makes the job relatively easy. For the time being I'm just keeping the case on so I don't have to pull the glass off again (granted this means not being able to use the fingerprint sensor)

I see, I also purchased a replacement battery for my N5 at the same time. I didn'tbget an aftermarket one though, I got one from a teardown. It was cheap too, under $10. I've been using wireless to charge it. At one point I thought the battery was going bad. It wouldnxt charge past 86%. For a week or so. Then mysteriously it started charging to 100% fine & still does.
I still use it at home for browsing when my N8 is charging wireless. I'm trying to avoid using the USB whenever I can now since my N5 USB port crapped out on me. Odd, this is the first phone I've ever had to have tbe USB port go bad on me. I'm pretty good with taking care of my phones. Hopefully when I open it up it might just be a loose flex cable or something.

If not, I'm kind of SOL because if it's something on the main board I would likely just need to get a new phone (can't imagine how expensive a 256gb internal storage board would be brand new but for the price I would feel safer just buying an entire phone).
Really wish there was some way to get Samsung Korea to repair it for me but I don't speak Korean well enough to have that kind of discussion yet, and who knows if they would even agree to it.

I have same problem my 4g 3g works fine but no 2g signal at all my operator 2g frequency is pgsm 900mhz.. I checked with other operators 2g working fine on 1800mhz... It's dual sim phone. Changing slot doesn't help either... So what's the possible cause...? My phone is in warranty but service center is 250 kms away.

there is a possibility you touching the connections could be amplifying the signal. Did you insulate yourself to disprove this?

Possibly, but since it was affecting only when I applied pressure in a specific angle I don't think I was acting as an antenna. Also, since heating up half of it with a hair dryer seems to have stabilized the connection a bit (it sits around -90 dBA where it was bouncing between that and -130 prior) it seems very likely that something with the board itself is flawed. I'm going to put just the usb / antenna board in the oven tonight to try and reflow all the solder and see if that will fix the connection issue since I can't yet buy a new replacement piece.

Speed mobile data drops

Hey guys Help me please
my mobile data speed drops
and cant reach high speed my friend in the same street didnt have this issue
because not a coverage problem
what can i do guys please help me

Are you using a wallet case with a magnetic clasp? There is a possibility that the magnets used in the clasp maybe interfering with your device's cell reception. If you are using a Metal Frame Case held together with magnets, your case may also interfering with your devices cell reception.

Are you on the same network as your friend? It could be an issue with the network coverage. If you are on the same network. Then I would take your device to a Samsung Service Center and let them take a look at it.
