Hi
recently bought a Samsung S7 US Cellular to us it with GSM. I updated the firmware to the latest version via OTA and as seen in other post I went to network and choose my network. But the thing is that it is only showing 4G icon and the bars are empty but the phone does have signal. Only when I make or receive calls the phone will show the signal strength. As soon as I hang up the bars go empty again.
What could it be?

Nothing it's normal to have 4G and no signal bars

hello all ..
I have a question.
I have the i727 phone with Cyanogen and Rooted. 4g icon does not appear in the notification bar, the connection works flawlessly, appearing H, H +, 3G but not 4G icon. What does that mean? before when I was working the STOCK ROM 100% sure the 4G, also tell them that in my country there's Connect 4G. but I'm not sure what type of connection that handles the phone. I downloaded this: << radio att-I727-UCMC1-no-csc-no-ril-cwm >> and I've installed, but still the same. I've also changed the APN, choosing the type of APN I select LTE but in doing so cut the signal. (apparently the phone is not supported)
Details:
Before: ATT & T STOCK JB 4.1.2 Rooted
Now: cm-10.1-20130607-NIGHTLY-SuperSU skyrocket + Root file-0.93-Busybox-1.20.2
Is there a solution?
Excuse my writing, I did it with the help of google translator but stepping reviewing the words to match the text well.

Thank you!

The stock AT&T ROM shows 4G for HSPA/+ but 4GLTE when there's LTE available. Cyanogenmod reports the actual data connection. It shows H/H+ for HSPA/+ and 4G for LTE. That's probably the confusion.

far as I understand, ATT&T has a fault, shows 4G icon when in fact that is not a Connection Connect 4G. I mean, I understand that: 4G is not the same for H+ because H+ is actually 3.5G. it? is this correct?

Correct; AT&T shows 4G even when it is only actually 3.5G. You were probably only getting H+ all along, but AT&T's software misrepresents your connection.

finally! I get it now! ... thank you very much! it is unfortunate that these errors come from the factory that exist only to confuse people.
10 minutes ago, I called my local operator, and said that the 4G or LTE service is not enabled yet in my country. (Just right through usb modem for LTE notebook works here, but not for mobile phones) so which I now understand that 4G phone on the screen showed when it was actually connected to a 3.5 or H + that would be the same thing ...
Is there a bug in the SGH-T999 4.3 (UENC2) firmware relating to radio frequency switching while on a call? I am fairly certain from testing that if I am on 4G (HSPDA+. I do NOT have the LTE phone) during a call, and am driving into an area with only a strong 2G tower, that the call gets dropped instead of switching me over. I can see the radio lose all the bars and then change to a full strength 2G signal as soon as the call gets dropped. I can then immediately make a call with the 2G signal.

I believe you want to go to T-Mobile Galaxy S 3 forum. This is for the T-Mobile Galaxy S 4G.

The 4G service at work between 8:30am to 5:30pm is literally unusable. I have 3 bars but as soon as everyone shows up, the data literally slows to a trickle. This wasn't always the case and I'd like to test the modem in 3G mode. My theory is that the 4G uplink is saturated but possibly not the 3G pipe. I don't believe the software provides this functionality to the user normally but since my device is rooted, is there a way to temporarily tell the modem to switch to 3G? I'm proficient in linux/unix and comfortable in a shell environment so a solution along those lines is fine for now.

Thanks for the suggestion. I iterated through all of the options under "preferred network type" e.g. WDMA, CDMA, EVDO, GSM, etc. Changing the mode would remove the LTE symbol from the phone (and disable data) but I could never get the 3G symbol to show up. Is there another option I might be missing?
That's odd. I'm on 4.3TW and the CDMA (prl) option works.
Are you sure 3g data is present at your location.?

I can remember having 3g at one time here but I'll wait to answer that until I get home where I frequently get dropped to 3g.
But, I noticed something interesting in looking at the power metrics. As I said I have 3 signal strength bars and the 4G LTE symbol. But this app says I have -61 db(71%) LTE RSSI signal and 2db(44%) LTE SNR. Doing some google searches I found a verizon document that says that RSSI should be greater than -58db and SNR should be greater than 12.5db for LTE to work correctly on their network. So that would seem to indicate why my data performance is bad and not necessarily a saturated uplink to the tower. So, is the signal strength meter actual reporting CDMA (voice) RSSI?

I confirmed that the app won't push me to 3g at home either and I am frequently on 3g there.

hah, and now I'm at work and realized, my work phone is 3G (verizon) only and its got 5 bars. Any ideas what's going on?
Hello guys. I had a T-Mobile Galaxy S7 but i sold it months ago so now i wanted to go back to the Galaxy so i got the international unlocked S7 G930F. I notice to start that it does not says 4GLte never only 4G. So i was thinking maybe the international name for 4GLte is just 4G so i let it pass but now i notice places where i had 3 or 4 bars 4gLte on the tmobile one, with international one i see 1 or 0 bard 3g or H+. Until now i have no call drop. But my question is. Is the T-Mobile better for signal to use on tmobile network or is the tmobile showing me fake signal while the international is showing me the real deal? I still have time to return it and get the tmobile one i just got it for the 8 core processor. Oh and i have a nexus 5x and he connect to LTE too were the G930F connects 4G and the nexus is unlocked too so i dont undestand.

Hi mate
4G or 4Glte they are the same , marketing mostly , some firmware show it as 4G other as 4GLTE or LTE all are the same
http://www.pcadvisor.co.uk/feature/mobile-phone/whats-difference-between-4g-lte-3605656/
Regarding signal strength the only way to know who is saying the true is with a signal meter , apps like PhoneInfo
http://forum.xda-developers.com/showthread.php?t=2709931
have a monitor where it shows you the signal strength in dbm and not just an image , with a dbm value you can truly compare

Thanks man. I used LTE Discovery and they both connected to LTE using band 4 and the strength is the same. They both turn to full GSM while on call and then back to LTE band 4 after call. So is marketing thanks.

That sounds about right , voice calls use GSM , unless your regions have VoLTE , LTE is used only for data . cool is all clear now
As stated above, it stays at Edge forever. I tried 4G switcher, I tried flashing a MM Modem. Is this a known bug or hardware issue? Also tried network reset and a different SIM card. Any solution to this?
Go somewhere with a better data signal on that network?
I tried in multiple locations. It won’t switch to 3G or LatE, shows full bars on Edge.

It will stay on Edge if there is no 3G/4G signal
Check with another phone on the same network/carrier, if that gets only Edge too then your signal is bad in your area

It depends on where are you located. Nowadays, we've got 3G everywhere so it's strange.. did you contacted your carrier?
