Hello guys, now with these smartphone with thousands of sensors will give priority to other things but it is lost sight of an important thing and that is that are used for calling. I have done several tests with various android phones and I found that the samsung s4 has a radio signal reception even worse than a samsung corby.Have you found the same thing? The test I made with different operators and looking at various areas in the information of the device and not taking into consideration the bars of the line. I also tried to change the version of the modem and reset. Nothing to do.What do you say? Thanks

Hi guys,
Does anyone know how can I improve my phone's signal? Sometimes it's very low, or oscilating between 1 and 2 bars. This happens at home, at my office, in closed areas mostly. But it's not a network issue, because I have friends on the same network but with different phones and they don't have this problem. I think it might be some code that I can use in the diagnostics screen to improve my signal, but not sure if I'm right.
Thank you.
The later firmwares solves some of the reception problems with the Omnia 7, but it still is a bad phone when it comes to reception and general HW design, unfortunately...
I am on my third replacement because of reception/connectivity issues, the signal appears to be strong but placing your hand around the back of the phone at the bottom causes the signal to degrade significantly also network data is very touch and go. I can be in the middle of town with a perfect HSPA signal and get very mediocre results sometimes it just doesn't work at all. I have tried three replacement SIMs, changing the GSM voice codecs, flashing different baseband radio firmwares all with no positive results. I also tried my partners SIM which is on a different network and had the same problem. I'm just starting to think that the antenna design is not very good and has low-gain characteristics, although that wouldn't explain why the connection is still unstable despite the baseband reporting a strong signal.
Another problems is absolutely terrible call quality, there is lots of white noise in the background, speech is distorted sometimes, pops, clicks, and just general instability. I've read so many different threads on many forums with people describing the same issues, and they too went through many replacement handsets and different SIM cards.
Please someone tell me there is a fix for this or it is at least a known issue otherwise I'm going to return this POS and get the Galaxy S4 instead. My previous phone SGS3 was great with reception! Bah! I'll cast it to Davey Jone's locker... release the kraken!!

You can try setting your phone to LTE only.
Type in dialer:
3845#*802#,then the secret menu will come up...Then:
1. Go to LTE-Only
2. Modem Settings
3. RAT Selection
4. Select GSM / WCDMA / LTE auto or what ever selection you want
Job done...
P.S If you have another D80x just enter your model number instead " X " in dialer etc: 3845#*802 or 803 or xxxxxx (not my work BTW)
Or seriously consider changing phones.
I've had fantastic reception on my vs980 but maybe your area vs. Carrier vs signal just isn't going to cut it.
Sorry man, love this phone way more than the s4... The s4 sure is pretty though.
Hello gents,
before you dismiss yet another S4 WiFi issue related post, keep in mind I am a Network Administrator for a living. What I do know well is wireless, what I don't is why my and many other's S4s are plagued with the WiFi issue.
If one is to search Galaxy S4 wifi problems, you will find a whack load of results with basic answers that don't resolve the issue. I am one of the lucky owners of a I337m Galaxy S4 that is a perfect phone, except the WiFi is absolute wonkers. My S4 is extremely inconsistent with being able to connect to 2.4Ghz networks, though 5Ghz is fine. I have attached a gif as an example of what occurs, though the signal is strong it refuses to connect instantly or gives "authentication error". There are good days, there are bad, but mostly bad.
I even gone as far as taking the phone apart and replacing the WiFi antenna with an external modified version, trust me it is NOT an antenna issue. I came across a youtube video of a fella with an i9505 who claimed to be able to fix the wifi issue by changing the baseband. This I would love to try though as far as I know there is only one baseband for the Canadian S4 if I read the forum posts correctly. At&t has a few which I wouldn't mind trying, but is it possible to flash the baseband from Bell to At&t (i337m to i337)? Would that even affect the Wireless functionality in the phone, or is it purely for the cellular network?
Hi
For a very long time I've been having signal problems, it just suddenly stops working and I have to reboot to get any signal back (airplane mode on and off doesnt work).
Its a GT-I9505
4.4.2
Goldeneye Rom
Greetings
which network? might be a local network issue?
I'm with 3, and although officially their website says that there's no planned maintenance in the area, i quite often drop signal when I'm at work recently, even though it's worked fine until now. I think a lot of people on various networks get the occasional network issue though. I think companies are constantly "upgrading" things, leading to network outages. I don't know why they don't just leave things alone. I used to have perfect signal on t-mobile when it was 3g, but as soon as they changed to ee and started to move to 4g, I got no signal, ever....that's why i switched to 3 in the first place, but now that they're "upgrading", same stuff again!
Its not the provider, know a lot of people on the same company and only me and my brother (same phone same firmware) are having this problems.
I read it coul be the 4.4.2 firmware, but dont know if only updating would fix it.
I had this problem on an earlier version of a cyanogenmod nightly. Most likely is your custom rom causing it. You said it yourself. Both you and your brother, same rom, same phone. Try a different rom or different version of the same rom.
I am having bad signal all day long wherever I am. I wonder if i can change modem to see if there is any improvment ? I am using XT1642 with " M8952_70030.25.03.62.02R " baseband version . I want to change modem to get better signal ? or is there any thing i can do to improve my signal rather than changing lte to 3g ?
No, you cannot and you should not play with it.
Your attempts to play with modem will give you more troubles (SIM not working, IMEI lost, etc, also a cause of losing fingerprint sensor)
If you search in other threads, if modem is corrupted/changed, then they have such problems and they are unable to get original baseband back..
So keep it as it is.. that is something that Motorola gives updates for it.. you don't touch it..
thank you for your comment but I want to see my options cuz with this signal quality I cant use my phone at all mobile standby drain bad phone calls etc.
That's something you need to ask to your network provider.
Best will be if you ask your friends/family near your area for which network they use and how is the performance in that area and choose another network..
From ROM side, it can be 'ril' issue, but most of nougat roms and stock rom are best without any ril issues, can't say about oreo.
Nothing else you can do for this issue...
My sisters phone has name signal quality with mine in terms of dbm criteria yet when I looked at her battery stats I saw that she has no battery drain caused by mobile standby that interesting.
ps: she uses samsung galaxy j7 exynos variant
