Good Evening
I just recently acquired a Korean Samsung Galaxy Note 4 from a Mobile Flea Market in the Philippines
When I tried to put a SIM Card (Sun Cellular) in the phone, I notice that if you turn on the phone, there is no signal in the network bars when I am inside my house so I went outside and the phone already acquired only a few bars of signal. Sometimes when it goes up to 3 bars it just go down and fluctuates.
I tried to put the SIM Card to another phone (Samsung Galaxy Grand Max - Also Korean) and what I am amazed is it manage to capture the full bars of the network itself and much better if you go outside .
Is there something i need to adjust to my Korean Note 4 but why my Korean Galaxy Grand Max has already acquired the full strength of the network? Is there a problem with the phone or do I need to go to a technician to fix the signal?
Will upgrading my firmware from S910S-S910C might repair the problem in the signal?
Thanks

Hy friends, I have note 3 n9005. I have isue with network. When I try to choose network mode i have option WCDMA/GMS, just WCDMA and just GSM. No LTE options, but my operetor Telenor Serbia dosnt suport LTE network. No big deal about that.. Problem is when I choose WCDMA/GMS (auto mode) my network is weak. I have some friend and they also have note 3 ,on same network and same isue. They sad me every note 3 have same problem in our town. Problem is in my house, or every place where signal is a little bit weaker I cant sedn message, or cant receive call.. I am not available in that moment. That friend reccomend me to choose just GSM and problem is solved. When I choose GSM mode signal is normal, like on my s2 plus, my old phone, on same network and same number and sim card. But if I choose GSM internet is to slow and I can use just for whats up, to send and recieve text messages. Nothing more.. What you think is this a problem with Operator in our town, Bad signal? Or something other ? On many phones before Note 3 I had not that network isue. Before Note 3 I was galaxy s2 plus, xperia pro, samsung wave. With no isue.. I am on stock 4.2.2 NA6, rooted. Thnx !

Baby 3G signals are always weaker than 2G signals. Everybody has the problem. I am from India and I also face the same issues on my Note 3 SM 900 4.4.2.

Hello
i have currently 3 smartphones.
Galaxy S3 with Cyanogenmod 10 (stable)
iPhone 5s
Galaxy S4 (since 2 weeks) with Cyanogenmod 11 (M11).
I bought S4 because my S3 screen was broken.
My problem is, S4 stays on EDGE although there is H+ or 3G mobile internet.
Example.
I'm driving back to my place. Park car in garage. S4 changes from H+ to (E)dge. Everything is ok.
Now i go otuside and my old S3 and iphone changes very quickly (few secodns) back to H+. My new S4 doesn't
It stays on (E)dge but there is faster mobile internet available:-/
My girlfriend has Galaxy S3 (stock rom) and i ask her "what kind of mobile internet do you have" (we're in same network) and in the most cases i have EDGE and she has H+ or 3G
Same situation at work.
On my desk S3 had H+, iphone has 3G and S4 has Edge. (all devices in same network, German Vodafone)
It takes minutes or sometimes longer for s4 to change automatically to H+
Last week i had stable CM for S4 (10.2.1) and it was the same.
Old S3 tries pretty often mobile internet. I see on display changes H+, H, 3G, E, G within few seconds.
S4 is stable on EDGE, but it shouldnt.
Any ideas?
How can i enforce S4 to play with the mobile internet Letters and taking the fastest?
Unfortunatelly i don't have LTE in my contract.
It's really annoying if you need fast internet.
Switching gsm module off/on helps in the most cases.
Kind regargds,
topek
In my opinion,
Temporary fix would be manually toggles 2G/3G/LTE, If you wanna stay in 3G just put WCDMA only, same goes to LTE.
Possible permanent fix is to flash the correct modem for your country. It is advisable to download latest firmware available for your country and flash it through Odin, or if you can, extract the Modem.bin from the firmware and post it here, i can make it flashable zip or others can too.
Hey guys. I just bought the sm-n9100 duos and i am having the issue that the sim 2 is losing signal after 5 seconds that phone is turned on and shows no service even if i am in a full coverage area. I understand that this sim works only in 2G. It is weird that sometimes I have signal in some specific places but the majority of time not. Does anybody have the same issue?
Hi, Posting for a friend. They've got a brand new Vodacom (South Africa) Note 4 but running here in Zambia. She can't seem to maintain a data connection for any longe than 2-3 minutes before it stops for 3 minutes and then comes back on. My theory is that since we don't have proper LTE here it's trying to register to LTE after it gets to HSDPA and then resets itself. I used to remember the code *#*4636#*#* on m S3 to get into the Phone information screen and lock it to WCDMA only - I tried it through the Samsung interface but no such luck already.
Am I missing anything here? Is there a different code I should be using?
I have the S7 Edge from AT&T (SM-G935A) and I get terrible reception at work. I have to turn airplane mode on and off 3-5 times during my lunch break just to send a few texts. I also have an older unlocked Note 5 (SM-N920C) which will struggle a bit but will still send and receive every text after a few seconds (20-30) of spinning its little wheel. So the question is why would an unlocked non carrier specific phone lock onto the AT&T signal better than an AT&T phone? I've been into the AT&T store and nthey seem to have no idea. The S7 Edge works great anywhere that I have a couple bars of LTE but when it's struggling with 1 bar of LTE or just plain 4G it's not so great. Any suggestions?
That type of subtle difference in coverage can be caused by the little differences in design. Phones today mostly use the frame for the antenna, so Samsung has to make adjustments for the edge, and the Note 5 simply has more room for the antenna. I haven't pulled the edge apart, but that's my guess based on years in the industry.
The other possibility is that it's struggling to keep an LTE 'enhanced' connection for HD Voice and video calling, which of course an int'l Note doesn't have. Try turning off enhanced LTE in mobile data settings & see if it makes a difference. Or maybe try switching to the HSPA+ 'wap' apn and maybe if it isn't always looking for LTE it'll hold the connection longer
Motorola phone for u bro they have the best signal of any phone I've ever used. Also some believe the way you hold it matters. And cases may effect signal strength. Some buildings affect signal strength as well maybe try a different location.? The note gets better signal because of the size.

Thanks for the suggestions. I switched to the unlocked S7 Edge (935F) and it works even better than the Note 5 did. It makes no sense at all.

i have same problem,any fix?
FYI, the code you show is incorrect, it should be *#*#4636#*#*. I get an invalid code error message if I use your code.
