newbie owner of an Evo LTE, and i'm wondering if the phone has signal issues. my wifi signal strength seems to vary from 0 bars to 4 bars (typically staying around 1 bar). I remember reading a while back ago that these bars mean nothing for data speed. anyways, I've ran some tests on speedtest app, and my wifi speed has fluctuated from as low as 100kbps to over 10mbps at different times at roughly the same location.
The time when i have the most issues is during skype, dropped calls, etc. I sometimes use a bluetooth adapter and sometimes don't and have had issues regardless. so my question is does the phone have a weak wifi antenna or something?
No. Change your wifi settings to
"Always on" and set the frequency to 2.5ghz if you haven't already.

I know this was a big topic of discussion regarding the Intl Version. My wifi range is weak on both 2.4 ghz and 5 ghz. I have an Apple Airport extreme which broadcasts both channels simultaneously so I have tried both networks.
My (now my wife's) iPhone 4 gets 75% signal nearly 45 feet away on 2.4 ghz while my Galaxy S2 has 25% or 1 bar.
I have used wifi analyzer to hop on the channel with the least interference so it's definitely not the router.
My iPad2 on 5ghz network has all the bars at the same range while Galaxy S2 remains 1 bar on 5ghz.
Is this pretty standard wifi performance for this device?
I've noticed this as well. MY iPhone had a better wiring signal. Will a new radio fix this maybe? I remember having the same issues on my HTC Fuze...

Odd, my friend brought over his iPhone4 a few days ago. We placed both phones on the counter next to each other and ran a speed test. My SG2 was over 10mbps on WiFi.... his was under 5.
I didn't test distance though...

You can't rely on a software-indicated signal bar.
Connect both phones, and slowly walk away from the router until the signal in each drops. That will give you a better idea of real range for each.

Very true.. I stop short of saying the iPhone is 'lying' to you, but they have notoriously been very loose with their reporting of 'strength'. I have done wave form analysis for over 20 years as a ham radio operator, and, as a wireless network fanatic building wireless links at 1/4 mile for very remote areas of a state park. I had both the 3g and the 4 and both were lots of bars, but dropped very quickly when walking away. I do like the idea of the wi-fi analyzer app, but even it has a delay built in that might make it a little misleading.
Just realized that that thing I had to climb up to get to my front door is actually a Verizon Cell phone tower!
So, just noticed this condition today and thought I'd share. I have a Smart Action set up to enable my Home Wi-Fi based on location - Trigger is my location; Actions are to turn on Wi-Fi, turn off Data and Max Ringer.
While home this afternoon I just happened to look at my phone and noticed that my battery seemed to be dropping a little quicker than normal and my cell signal strength was max bars which NEVER NEVER happens at home - kind of on the fringe in my house and I'm lucky to get 3 on a good day. I checked network strength and my 4G was 2147483647 db. Gotta be a world record, right? oh wait . . . is more db bad?
Just got me wondering if, while on the fringe, the radio actively looks for a signal (like it does between 1X, 3G and 4G) and maybe gets stuck in some type of high output state. Would explain some of the intermittent hi-temp, unusual battery drain I experience occaisionally/intermittently. Just so we're clear - I'm not complaining at all about my Maxx battery.

I thought after 120 db it actually means you've lost signal.....optimal is between 80 to 120....
I could be wrong
I saw that exact same thing on my Maxx the other day. I also noticed battery declining due to it. Not sure what it means though.

It means your have no signal, and your battery is dying from your LTE radio trying to find signal. dbm between -80 and -120 is not optimal, that is the range where verizon techs will tell you that you may experience data connectivity issues. The lower the dbm the better signal you have, however most extended 4g service areas are at this quality. I have seen some locations, closer to the towers, where I have gotten signal around -60dbm, which gave about 38mbps down and around 16mbps up.
I ordered a sleek 4g signal booster from wilson electronics, which will get here tomorrow, and will let you guys know how much improvement I get in areas with different signal strengths.
i've seen it countless times on my razr. I think it's just a bug
No signal but my signal bars show as full? That makes no sense whatsoever. I think I have to agree that it is just a weird bug.

I'll tell the truth. Wilson electronics sleek 4g-v is not going to improve SINR signal strength (that's what you need for better LTE speed), however it will improve RSSI signal, but this is not going to help for LTE. If you want a good LTE amplifier, you are looking to spend about $500 that includes outdoor, indoor antenna and SINR amplifier. SINR is more important then RSSI or DBM for LTE
I noticed on my G3 that if I have only a bar or two of 1X or 3G, everything will stop loading. For example, earlier today I was loading up a large image using 3G, and it would stop loading whenever there was one bar of signal and would resume loading with two bars. I also noticed that websites would time out when I had one bar but with two they would load. It doesn't happen on LTE and seeing this on 1X could simply be because 1X is too slow to load anything, really. Anyone else experience this?
I haven't found myself in this situation yet with my g3, but my galaxy s3 displayed the same behavior. This isn't too surprising for a fringe connection, a classic trick to boost signal is to reduce bandwidth (everytime bandwidth is halved, signal increases by 3dB). If your connection is poor enough it stands to reason your bandwidth would drop to useless range.
Mine does the exact same thing. You may be in a poor coverage area.

Most of the time Wi-Fi is at 1-2 bars along with LTE.
Noticed this problem in Hong Kong,China and Taiwan. Various dim cards and various Wi-Fi routers.

i m facing the same problem i have note 4 that is quite well than s6 edge in 3g and 4g
This could be the cause of some people's battery drain as their phones keep switching from LTE down to 3g. If this phone was better tuned for LTE it would be more battery efficient.
Not sure a software fix can do much about this. Its probably the antenna design, but we can live in hope!
My Wifi is fine.
However, I've been having poor 4G since day 1. I keep having 1-2 bars of 4G consistently at my workplace where my G3 did 3 or more bars.
The thing is, it does stick to 4G pretty well and not loose that 1-2 bars easily to downshift to 3G, so I am not too concerned. Voice calls and data speeds are also not affected. It's just that vidual indicator...
my wifi and data signals are excellent. haven't been to a spot where there's good lte signal
Always use device status to read signal in dBm.
Many phones' "signal strength meters" are far from accurate often showing much higher perceived signal than reality.
My S5 was like that.
This may just be corrected now in as much one bar for -112dBm (instead of three) is more accurate, relatively speaking.
A device should only show five bars if the signal level is very strong, say -65dBm.
Problem is most of the time people would never see five bars. Carriers don't like that.
Perhaps we need to change to an advanced "tech" mode where the signal strength readout is in "S" units with 9 being the reference and stronger signals show in "dB over nine". Like HF transceivers and CB radios (anyone remember those? )
I would be happy with -dBm on the status bar instead of a series of bars. iOS allows for it and it's accurate. Can't believe it's not baked into Android being it's the choice OS for techies.

Hello, compared to Note 4 S6 really hurt my Edge captures the mobile network.
Hi,
We go on vacation each year to the same place and GSM/2g/3g/lte signal is very poor and varying here. With meter I measure signal strength from -80 to -110 dBm at the same spot. It probably varies due to seaside proximity.
What bothers me is the fact, that when phone looses signal, two weirdos occur:
1.) I need to reboot many times to regain access to my operator...same with other family members, and we use different operators. Why does not phone switch from no signal to my operator by itself always?
2.) Maybe related...cell meter app on my phone show quite strong signal of -80 to -90 dBm all the time when no etwork is found, but network operator name is "none". No calls can be made, even 911 calls end with network error. But signal is strong. What's this? Is this some dormant signal, which I detect practically everywhere, when no network is found?
Above symptoms are present on Samsung s7, s10 and on LG g7, so it's not phone or android version guilty.
Explanations welcome.
