Phone shows -70dmb in signal but always 1 signal bar? - One (M7) Q&A, Help & Troubleshooting

hi guys. I have an annoying isssue while using AOSP or CM-based roms. I have a m7vzw. The signal is good when i use sense or GPE rom, but with aosp and cm, my signal bar always show 1 bar, sometime it even drops to 0. I checked phone status *#*#4636#*#* and network type is global, signal strength is -70dmb, ASU 255 (or 225,i dont remember). In battery history chart, the color of signal on is orange-red (while GPE and sense shows green,which mean good signal) and has little spaces like they were dropped to no signal
i dont have screenshots right now because i restored my backup, but i can re-install if needed
Is there anyway to fix it? i switched to GSM in preferred network but it doesnt help. Also i still have H+ data (my country doesnt have LTE yet)

WCDMA signal horrible

I've flashed my phone countless of times now over the past months and one thing I was hoping for would be better signal strenght for WCDMA mode... I live in Switzerland and my provider is sunrise. Whenever I'm using WCDMA mode the signal is just horrible. Mostly 1 bar or sometimes dropping to zero. 3g and H works most of the time, but the signal is bothering me.. I've tried different modems etc.. but nothing seems to change.. Does anyone else have this problem?? what can I do about it? GSM has full bars most of the time and that's why it's so weird.
also worthy to note is that people hear an echo sometimes when they're talking to me both in GSM and WCDMA mode.
it would be great if someone knows how to solve this problem...
have you been on your providers website to check the coverage in your area ? they could be a fault on their part affecting your signal strength
Im on Vodafone UK and i have terrible 3g signal, I can only use 2g/GSM otherwise my phone doesnt recieve 1 bar of signal - bit of a bummer when you have a smart phone and unlimited internet
Finally, How was your signal before you flashed ? when the phone popped out of the box ? was it still poor then ?

[Q] Signal strenght problem

So if we have root finally can someone tell me if there is any way to resolve the signal strenght problem?? It looks like Droid 3 has different perception of signal strenght than my Motorola Milestone... When my milestone has signal about -83dB it has all 4on4 bars of signal strenght, and on Droid 3 -80dB means 2x4 bars...
the problem is when the signal is around -90 dB... Milestone has than 2on4 bars and Droid 3 has 1on4 bars or is Out of service...
Is there any file in the system that manage D3's perception of signal???
Hope You can help me somehow...
When I got this phone I wondered about that myself. But I never had any issues with calls.
I'd say a new rom might be the answer, but hey...
This sounds like the same issue with Droid 2 Global. Try switching to 2G and see if bars "increase" so to say. On D2g it is more of a cosmetic issue, even Cyanogenmod ROM for that phone applies fix, so bar count is displayed properly.
Edit: on Motorola XT860 this works normally (compared to D2g it seems to get better reception too). For non-Verizon users, I strongly recommend this version over the US D3
To which setting do you put your "Set preferred network type" under *#*#4636#*#* ?
Mine is set to "GSM Auto (PRL)"
Also, TELUS doesn't have a 2G network, so I can't test that option.
My phone is rarely at 5x5, mostly 3x5 or 4x5. My previous Milestone almost always had 4x4.
You can also check your signal strenght over time if you check your battery stats and click on the graph at the top of your screen.
The first bar should be Green, yellow, red or gray depending on your signal strength.

I've had 3 replacements, first for out of service, then also screen and vibrate issues. All had the loss of service even with lots of towers near me. Usually a reboot fixes it but it's getting very annoying . Had a high level ticket opened with them and eventually was written off as a droid 3 issue and closed. They just don't want to help.

I am with Rogers and signal indicator is most of the time on 5 bars. I've seen it go down to 4, usually indoors, very seldom down to 3 or 2. I am yet to see 1 bar only or no bars at all (which wasn't at all unusual on my D2G
In that case, it must be a phone model vs cell towers (Bell/TELUS, Rogers) issue.

I tried to change it to 2G only and it works and it shows 4/4 bars... however I use internet so 3G/HSPA is my preffered network and on 3G it shaws usually 1-2 bars and from time to time it drops the signal... It has to be software problem because when I change it to GSM Auto PRL from GSM only and it was at 2G showing full range it stays at 2G but shows 2 bars... so another MOTO bug... :/ but i would like to find out how to change it...

(Q)HTC one low signal bars UK EE/Orange

i recently unlocked, rooted and s-off my htc one, on stock i used to get around 5/4 signal bars and now i only get two/three.
im currently running trickdroid 7.5 rom 4.2.2.
so im looking for a radio which would work for orange/EE in the UK.
please can someone help, or point me into the right direction
this is the one for the 4.2.2 firmware

Are you sure that it is not the same level? Don't be fooled by the bar looking different, remember that it might show 2 bars of LTE but that could still be better than 5 bars of H+ (as an example).
So if you used to get 5 bars of 3G but your now getting 2 bars of H or H+ then you are better off even though its less bars.
Please do not take this as me treating you as if you are stupid, I am not, I have come across a lot of people recently who thought the same, and it turned out to just be a different type of signal.
fixed
okk i just flashed 1.29.401.12 Radio and it's back to normal.
i found it here http://forum.xda-developers.com/showthread.php?t=2245615

thanks for the input but!
i never said i was using my data connection,
Same principle applies even with data off.

So if I have 5 bars when set to "GSM" only but 2-3 when set to "GSM/CDMA" .. that's as good?
I'm being serious btw, I normally set mine to just GSM as I seemed to have more signal but if there isn't any point then I won't bother lol ..I'm in the UK btw and on a network that doesn't support LTE (I think)

You can confirm the 'type' of signal you are getting at any time in the menu > settings > about part of the phone.
Your phone will automatically switch to whatever the best signal is available at any time, you don't really need to change your GSM/WCDMA settings, unless you really want to force it away from 3G connections (again this does not mean you have to have data turned on).
Cool, I'm not too fussed about what data type it uses as I rarely have data turned on, I just naturally assumed that by switching it from GSM'CDMA Auto to just GSM, meant that I'd have better reception, being that the signal bars went from 2/5 to 5/5 ... You learn something new everyday lol
EDIT: I checked my signal, and I mean my reception, not the data connection type, when switched between GSM/WCDMA Auto and GSM Only and there is a huge difference. I found this guide:
dB Signal - A basic guide
-50 to -60 (very strong, near a cell tower)
-60 to -70 (extremely good, rare)
-80 to -85 (normal downtown)
-90 to -95 (getting on the weak side)
-95 to -98 (weak, dropping calls)
-98 to -100 (bad, hard to stay connected)
-100+ (basically no usable signal)
When I set my phone to GSM Only I hover around -70, which is good, when I switch to GSM/WCDMA Auto it is a different story. I know it changes and finds the best signal, which I might add drains more battery on an already power hungry beast, but I was hovering at -100 which is terrible and often calls were dropping or people were saying it was engaged when infact I hadn't used it.
It's clear to me that in my case, GSM Only is the far better option if I actually want to use my phone to make calls ... Data speeds I'm not arsed about so EDGE is just fine with me.

Updated to 4.3 Firmware and have less signal bars? Read This!

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 !

No signal on SMT-705

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.
