Hi!
I have a strange problem. I am unable to connect to any of the GSM networks around me. But when I see the signal strength it's always good like -55dbm, -63 dbm, -69 dbm, -73 dbm.......never beyond that....
but still I cannot register to the network.
Anyone have any idea?
Thanks
I've seen some people post regarding less/lower signal bars when updating to the new radios which come with 4.3 and you have LTE.
At first I said "WTF" but then I realized... the bars are now sort-of working as intended...
Let me explain,
If you're connected to LTE, the bars are now based off your LTE signal strength. I noticed even at roughly -110 to -100 I only get one bar. I believe the bars start going up dramatically once you have a signal strength greater than -100 (for example, -95db, -85db) And we all know -130db is the cutoff before we lose LTE.
I figured this out once I turned the phone to "CDMA only" to test. Once on "CDMA only" I had almost full bars, (-70-75db for 3G/1x)
To conclude, if you're on LTE and only have 1 bar, you most likely/probably have great cell phone coverage as that 1 bar is determining signal strength for only LTE. When connected to LTE, you're also still connected to 1xRTT which is used for voice. LTE is only used for Data at the moment.
If you really want to test your cell phone coverage, you can get one of those programs to tell you both your 1x signal and 4G signal simultaneously.
Edit: I forgot to mention, Considering the LTE radio and 1x/3g radio are seperate, you're going to get mixed results depending on signal penetration through walls, trees, etc. From what I've seen so far, as of right now 1x/3g penetrates a bit better than LTE. But, really depends on your surroundings
Thanks for the info. Someone else tipped me off about this, and a few SpeedTest checks confirmed it. In fact, 1 bar with the 4.3 ROM produced slightly better results than the 4.1 ROM with 5 bars.

Yup, which makes sense because when connected to LTE on 4.1 the 5 bars are based off your voice coverage, not LTE strength.
Still seems kind of dumb. I'd rather know what signal I have to make a phone call rather than what kind of data I can expect.
Thanks for info !
Sometimes just 1 bar but internet working well, but 4-5 bars it is not working/slower !
Hello everybody.
I recently bought a HTC One M7. I'm satisfied with it, except when it comes to 3G connectivity and signal strength. I only have from 1 to 3 bars when connected in 3G, while with my chinese phone I was having complete bars.
Here is a little comparaison :
Code:
3G
chinesephone -91 dBm
htc -101 dBm
EDGE
-79 dbm (chinesephone )
-77 dBm (htc)
Sometimes with my HTC, it can go down to -107 dBm, without touching it (just by looking at the screen) !
I put in attachment a screenshot showing the dBm variation over time. Sometimes it can get a pretty good signal and suddenly having a bad signal and stays there. Please bear in mind the chinese phone doesn't have the same problem...
I did all the updates, I'm on 4.4.3 and Sense 6.0. What should I do ? Should I send it back for reparation ?
Thanks you!
Just want to ask if your smt 705 ever displays a no signal? The reason I'm asking is I noticed that on my device, the signal bars are always full even when there's no sim card.
Also if I'm on an area with no signal for a long time then went back to an area with a signal, my tab will show full bars of signal strength. However when you try to send a text, it will you that there is not connected to a mobile network.
Anybody having the same issues?
It depends whether you are connected to a WiFi network or not.
Is there a way to check signal strength of all neighbouring towers.
I know we can see this info for the current service provider you are using (the SIM you have in your phone).
I'm interested in knowing signal strength of other service provider's towers.
When we do manual network selection it shows a list of all neighbouring service providers but not their signal strength.
