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.

My friend has a Sprint S3 and I have a Sprint S4. We went camping last weekend and at the site service was very spotty. He was able to connect to 3g service on his S3 while I was only able to connect to roaming voice with no data on my S4. It wasn't like it was even coming in and out of 3g it just would not connect at all to data. I am running stock software and am fully updated. I tried changing my phone from 3g/LTE to just 3g and that made no difference. I turned off roaming and set it to just home network and it gave me no signal whatsoever. Can anyone explain this? Shouldn't the S4 work better than the S3?
Hi just got my new phone Galaxy S5 G900V from Verizon and I have some question.
I’m on official ROM 4.4.2 NCG rooted. I tried official 5.0 OC4 but I didn’t have root and some of my games ware lagging so I switched back to 4.4.2.
1- Which do you think is the best official ROM? Should I stay on 4.4.2 or update to 4.4.4
2- When I charge my phone and it reach 100% often as soon as I disconnect the charger the battery drop by 5-10% so I plug in again for it to reach 100%. Any idea why this happen? Also I notice the first 50% drop much faster than the last 50% is this normal?
3- Is there anyway to force my phone to use H+ only?
I don’t live in US and the best band here is HSDPA+ at work my old Atrix 4G had no problem connecting to H+ but my new S5 constantly drop data connection and the icon on the notification bar constantly change between 3G / H / H+ with the little arrows mostly gray. In network mod my phone say GSM/WCDMA/LTE and if I try to change it, it give only 3 option Global, LTE/CDMA and GSM/ UMTS and none of them is selected. I used Global when on lollipop and I had the same data connection problem.
4- I’m using a case which is plastic but it has aluminum back. Can this metal back cover interfere in signal reception and /or wireless charging? I plan to install one of those ultra slim wirelesses charging receiver.
Thanks
p.s. Sorry for my bad English.
So... my Note 3 is like new, no exterior damage at all, I've taken well care of it, but I'm having some problems with signal reception.
Using LTE/GSM/WCDMA mode (or LTE preff with CM based roms) where the phone prefers 4G signal, I have 1 or 0 bars of signal, I miss calls and texts and web browsing using data is really slow!
Using GSM/WCDMA (3G mode in CM based roms) I have like full bars but slow internet using data, I don't miss any calls or texts (at least I didn't notice it) but when I am in the train and I pass through a tunnel, the signal is lost and it never recovers, I have to remove my battery and reboot the phone to regain signal (my other phone, a Galaxy Nexus, loses signal only inside the tunnel, then in seconds it reconnects again like it should, I also have full bars everywhere and no problems with the same SIM card, I also have an LG G2 at home and LTE works very well with the same SIM on that phone, it's just Note 3 that has really poor or no reception at all).
I don't think this is normal and I don't renember having problems like this in the past, how can I fix it? Please help me since I can't find any info by browsing and everyone knows Samsung isn't cheap when it comes to fixing things with knox 0x1, and I am fine fixing it myself if I know what to do.
Do phones use different antennas for LTE and 3G/2G? Is it an antenna problem? How can I pinpoint the problem? How can I repair it?
Thanks in advance.
EDIT: forgot to mention, I've tested this on many custom roms (CM13, CM12.1, RR, N5 ports, S6 ports, Aryamod, Stock Samsung Lollipop, Stock Kitkat) the problem is the same everywhere so I think it is hardware problem.
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.

FYI, the code you show is incorrect, it should be *#*#4636#*#*. I get an invalid code error message if I use your code.
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
