[Q] Signal Strength - Onetouch Idol 3 Q&A, Help & Troubleshooting

What kind of signal strength are others getting compared to other phones they have owned. When I am in an area that has excellent LTE coverage (as consistently shown on multiple other phones I have owned) I am only getting about one half to 3/4 of the signal I had been getting. I have yet to get a full strength LTE reading on the signal strength indicator. I am also having problems with the signal dropping completely (no service) and then coming back at 3/4 strength? Very flaky.....

My AT&T signal was always terrible. Almost always 1 bar but sometimes two. I preordered a H2O Wireless SIM about a week before I got the Idol 3. My AT&T plan expired the day after I got the phone so I just popped in the new H2O sim into the idol 3. With the H2O sim I get really good signal, sometimes full; bars! The weird part is that H2O uses AT&T towers so I can't explain why I am getting better signal except that it could be the phone. Unfortunately I was unable to compare the same sim card in both phones. Overall signal strength is better for me.

i got the same problem i had a moto G lte had all of the bars then i put in my sim card and now i dont get much signal even at work with the moto i had all of the bars and this one i get like half then dissapears goes back to half then of a sudden all of the bars show im running cricket and as same as you we run on ATT towers

I had to set mine to wcdma/gsm on T-Mobile to get good coverage. It wouldn't pull signal unless it was 5 bars LTE.

Tmobile in SF. Brand new phone less than a week in use, also terrible signal. LTE Discovery shows I'm on band 4. Funny enough I still get calls and txt messages when displays shows not signal at all. This is one thing I hate in reviews, they all mention how fast and great display and audio, but none of them mention call reception. IT'S A FREAKING PHONE!!!

My signal sucks regardless of this being a Band 12 capable phone. I know you should never go by the signal bars, but rather the dBm's/asu, but my signal strength fluctuates constantly and doesn't even show signal at all until a few seconds later as if it "reconnected" to the network and jumps 2 bars. This phone needs a major modem update. I don't think I've ever seen my signal bar icon fully lit even when I'm outside. Maybe I just need a new SIM card.

My network is fine. AT&T/AIRVOICE. SLC, Utah.

I compare my Idol 3 signal to varying Androids i know that are on Tmob, it seems to be par for the course. Often it is half a bar better. It is certainly better than the OPO i sent back.

Q Fuze: how to read the signal strengh indicators..no,really.

I'm new to ATT. So I'm new to 3G. I used to have TMobile, which only has Edge. My signal with Tmobile was excellent. Normally everywhere I went, I had full bars. Well, greater than 80% of the time.
But with ATT, I get 3G, but the signal bars are normally 2-3 in those areas I go. Some places drop to one bar. It seems I can still make calls tho.
But one time I was in the store with 1 bar and it said 3G, I went on Opera. It switched to Edge(E) and the bars changed to like 4 bars. But it was slow. Similar to my Tmobile speed.
So my question is, whats my signal for the phone? Are the bars only to show signal strenghs for 3G and a different one for Edge? I would like to know when my phone is loosing connection.
If so, if my 3G is 1-2 bars, would I not get a faster internet connection on Edge, if I knew(if there was a way to know) Edge has 3-4 bar coverage?
Or for that matter, wouldn't my battery last longer on Edge at 4 bars than 3G at 2 bars while in standby? not connecting to internet, but just by the phone trying to keep a signal?

Signal Strength Issues

Anyone else experiencing a weaker signal with the AT&T One X versus other phones? I've had a Samsung Captivate and Lumia 900 at my work desk over the past ten months and have gotten 3-4 bars on HSPA+. With the One X, I only get one bar, and can't even send/receive text messages.
I'm in the middle of the first floor on a five story building... I would understand not getting a strong signal here, but the fact that my Captivate and Lumia 900 both worked fine in this same location makes me think something's up.
Actually, this phone has better signal than any other phone I've had.
I get a better signal than other phones. My bigger frustration is that it shows full bars when I have no data connection, or zero bars when everything is streaming just fine...
My signal is terrible. There is.no LTE in my area, but my HSPA sucks. I read something that said the antenna is on the bottom left of the phone, and sure.enough, when I hold it there I get 1 bar all the time. When checking battery usage stats I see lots of yellow and gray under Mobile network signal. Surprisingly thoug, my battery life is great, and I don't drop many calls.
Also, my speed tests are carp. Consistently getting 1-4 mbps down.
My phone had HORRIBLE signal. Nothing anywhere. Texts weren't making it out, and if they did it would be in multiples. Forget about MMS. And it got worse to the point where I was dropping every single call. Also was missing some Google Talk events. So I just exchanged it and got a new SIM card this morning.
In my office I was getting 0-1 bars, with the new one I'm at a pretty solid 3 bars. And so far no odd sms/mms/notification problems. I've already flashed the updated ROM, and rooted it. (the last one was flashed/rooted also) Doing a Titanium restore now...

Same here. As good as or probably better than my last phone. It could have to do with your area. I am well covered by 4G LTE; perhaps other networks are not as well received by the phone's antennas.

LTE poor signal?

Hallo, Vodafone Italy still not offers LTE coverage in my city, but there are some cells that already have it enabled.
I noticed that when I'm under 4G, my signal never got past 2 notches.
So I ask to who is covered: is this right or do I need RMA?
Thanks...
I'm supposedly in a very strong LTE area and I usually see two bars. Occasionally there will be three bars holding steady but rarely do I expect to see four (out of five). My speeds rarely change from 16-18 up and down (downloads always faster. Zero packet loss on T-Mobile. My Nexus 4, on the other hand gets low speeds and between 2-4% packet loss.

Are you talking about the signal bars in notification area as "notches"? Trying to see if thats what you said. If so, the signal bars do not dictate the LTE strength, just cellular call strength. The LTE download could still be great even in no signal bar areas as well, signal does not influence the data strength nor does data strength dictate the signal quality via the bars. Since the phone has to turn off LTE to "switch" to 3G in order to make calls, the "switch" may have something to do with the bars.
Thanks, that's exactly what I wanted to know! And, yes, Italians call signal bar "notches"...

question about cell radio signal

Hi guys recently I bought an unlocked g955u1 from best buy and am on Verizon. I've noticed that my cell signal has been reading a bit off despite doing the Verizon software update. My phone is almost always stuck on 3 bars lte according to lte discovery and the range of dBm will average -100 to as low as -108 which realistically should be 1-2 bars not 3. In the past the only time I've really saw inaccurate readings like this is when I've been on gsm carriers. It's not as much as a problem as more of an annoyance as everything works fine. My question is anybody know why it's reading so inaccurate?
The bars are more or less just approximate visualizations of the network strength anyway. It varies from carrier to carrier, as well as phone manufacturer. You're better off sticking with the dB display if you want a truly accurate reading. Imho.
I have a T-Mobile variant and have noticed the my DL and UL speeds are a lot faster than any of the phone I've had in the past. We live out from town and even on the Nexus 6 it shows 3 bars and on the S8+ I get all the bars and the DL speed on the other phones at my house are around 5Mbps and on the S8+ I get 17-20Mbps at the house now. In town it has gone up from 40Mbps to 55Mbps.
My ATT S8+ reception
While I agree that the dBm is what you should be looking at, I have noticed some funky things going on with my ATT S8+ in terms of reception. Using the same SIM card, placing the phone in the exact same place, my S6 Active has a signal strength of -124 dBm /asu 16/"In service" on LTE. The S8+ gets a signal strength of -113 dBm/asu of 0/"Out of service." To me this seems like the S8+ is actually getting better reception than the 6S Active but the phone is out of service. I also tried this same test in another location using a different cell tower. Same results, the S8+ gets better reception...but the phone does not perform as well. In location number 2 I have also notice the S8+ fish for better signal and switch from LTE to HSPA where the signal strength is -99 dBm but the asu is only 7.
Since I live in a area with weak cell coverage the S8+ is driving me nuts...I contacted ATT about it last night, will see what happens.
Also somewhat related:
I'm using a US Unlocked on T-Mobile, and I've noticed my signal dropping out in areas where I previously had great signal on my Pixel XL. My buddy (also on T-Mo) just got an LG G6 and had full signal when mine dropped out.
Anyone else notice a weak signal? If I flash the T-Mo firmware, will that improve my signal? Did I get a bad unit? I hope not as everything else is perfect, screen included.
i notice (with TMobile) that if i am in 4g lte, then move to area with only edge for a few mins, then back to the 4g lte area...my phone doesn't connect back to the best signal
only a reboot let's me reconnect to 4g lte

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Samsung Galaxy S10e's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.
I don't go by the bars I go by the dBm's. The way this phone reads dBm's you pretty much show no bars after 117 dBm's. All other phones I've had showed 1 bar at 117. -97 dBm right now but still only have 3 bars. Should have full signal. -97 is pretty good. Anyways, I have an app that shows dBm's in the notification shade and that's what I go by. More importantly is the fact that my unlocked 6t has Volte with TMobile and my S10e doesn't. Sucks.

Signal Notification
The 4G signal is way less good than with my ex Huawei P20. And when it goes from bad reception area to a good reception area, it takes a lot of time to catch the actual signal, sometimes I even need to put on plane mode and then put it off.
Long time to capture signal

This. Takes a long time (minutes) to capture a signal from one area to another.
Anyone has experience with dual sim use in this phone ?
I barely get connection on the second sim and feels like the first sim has even worse reception when a second sim is inserted.
I got this phone like 2 weeks and very disappointed for cellular strength. As mentioned above, often i have to put on airplane mode to get connected to the internet.
This phone has serious problems with reception. It never really bothered me, I got this phone since launch, (exynos variant, dual sim) but now that I don't have broadband until my new provider sets up their network in the house, I have to rely on my mobile data, and it's amazingly bad. I have 2 sims in the phone, but it doesn't make any difference if I remove one or other. I'm in the UK, it could be Vodafone's fault, however I tried my sim in my previous phone (honor 8) and the signal was better (in dBm ofc) and I also tried my gf's sim in my phone and the signal was worse in my phone. I've spent days searching for solution and it turns out Samsung might went cheap on antennas so there isn't much to do. I've tried some 3rd party apps, tried to force only 4g, also tried 3g, reset network settings, reset access point etc; no luck. I'll transfer my number to an other provider and hope that it will help a little bit but to be fair, I don't think it'll help.
