Galaxy S6 (T-Mobile, G920T) weak data signal/reception - Galaxy S6 Q&A, Help & Troubleshooting

Hey guys,
I'm going a little nuts with this problem. My previous phone (a LG G3) went bad on me (GPU burnout) so I replaced it with a refurbished Galaxy S6. I've had this phone for about a week, but I notice a considerate drop in signal strength. I'm getting EDGE (2g) way more often than LTE, and in general just slower data speeds. My plan has enough high-speed data, so it's not throttling.
By the way, in comparison, my wife's G2 is getting a much quicker data connection than mine.
Thoughts?

What firmware do you have? Maybe you should flash other modem to get better reception. Every phone have different antena moint in different place so the signal strenght depend of various things. Maybe you have metal case which lowers signal strengh. You have to check this and test by your own

The phone is not in a case, and I have the most current firmware for it.

[Q] Poor signal (LTE)

Hi. Does anyone noticed problem with signal strength on LTE mode? I do have non-branded version of S6 bought in Poland.
As I written, signal strength on LTE mode is very poor (1 bar, sometimes 2 bars). When I changed network mode from LTE/WCDMA/GSM to WCDMA/GSM it started to work normally (3-4 bars, but it's H+ only). Is there any fix of it, or we need to wait to OTA Update?
I have the same problem since I got the s6 in March
On other phones do you have similar problem or only on s6?

My S6 W8 on Telus loses signal and usually requires a reboot to get it to hook up again. Never had a cell phone that behaved like this before.

How is your Wi-Fi reception?

Where my wife's Moto G can pick up five networks, my GS7 can only pick up one!
Are you noticed poor wifi reception?

Yes, for me it's the same also. My old galaxy s2 shows me 9-10 wi-fi network but my s7 only 4 ....

For the most expensive top of the range phone available this is unacceptable. How can a budget phone (moto g) outperform like this? Hope this can be fixed with an update, though it's more likely to be a hardware issue.

Assuming Moto G has WiFi 'n' that is 2.4GHz which provides long range than WiFi 'AC' 5Ghz in S7

S7 has 'n' as well though. It's not that it can't see the other routers, it just goes out of range sooner. Probably an antenna design compromise.

If you have connected to 5Ghz network it's using AC. If not then there seems to be a problem

Poor Network and Wifi

Hi All, just a quick question really: does the Z5 E6683 have a generally poor wifi signal compared to other phones? I have a old LG G2 and an even older Samsung galaxy S2 and a friend's Samsung Galaxy S7 and if i put them together, the Z5 wifi signal drops in and out, but the others have 3 or 4 solid bars. The Z5 E6683 does get a signal if I move close enough, but I wondered if anyone else has done a comparison with other phones?
I have tried stock 253 and also the XperiaX 2.6R ROM. Oddly the latter is worse! But that is interesting because it made me think that the problem might be software.

Signal is quite low, anyone experienced the same?

Hi all,
My xperia xz having 1 bar reception almost every time, any has the same problem as me?
Sometimes 2 or 3 bars, and 4 bars is rarely happen.
I also tried my sibling's simcard(other telco), 1 bar in my room and 2/3 bars when i walk to main door. Any suggestions? Thanks
Mine seems to as well, in thinking it could be cosmetic issue?
Otherwise maybe the wrong baseband?
Not too sure. Was yours purchased through import or local supplier?

Yup, bought from local Sony centre.
My previous Xperia z had stronger reception tho.

Not sure then \o/
I have my Z2 and XZ side by side.
One bar less on the XZ.
It's not cosmetic : at places where I have from 1 to 2 bars on the Z2 (at work), the XZ is between no connexion and poor connexion.
At home, 3 bars on the Z2, 2 bars on the XZ.
(both without cases during my tests).
Mine appears low most of the time, but the signal is fine. Check with an app like LTE Discovery and see if the signal is really as low as it looks. I know that when I flashed a UK (and now AU) firmware to enable the fingerprint reader, the signal indicator lost a bar and always looks lower than the US one for some reason.
Mine also looks low but reception is always good and I have met been out of reach of had calls dropping. So I am not worried
But I do think my WiFi reception is slightly less than my previous HTC one m7

My xa is the same, always one bar with 4g calls but reception is just fine never had any dropped calls either..

Sitting in the same spot, my Z2 works fine while my XZ could not connect to Internet and calls are not possible. This is with the same SIM card tried. Where there is low signal, my XZ shows "No Service", not a single bar. Could not locate network as well. I already sent it to Sony center. Hopefully, they would not just run software repair and return it to me because I have done that and it didn't help.
Just found out the problem, the problem is not the phone... it's the telco im using. If I switch to LTE, some place that doesn't have strong LTE signal, the phone will get low reception. If I allowed max connection to 3G, I get full bars. So no worries and thanks.
it actually is a bug in Sony firmware. They way they calculate the display against the signal strength is wrong. why on Earth Sony shows 1 bar with 86db and 53 asu while for example Huawei p9 for exactly the same signal values shows 4 out of 5 bars.
XZ signal display is simply unrealistic.
In my case, xz dual, Polish operator play, net signal is best I had in Android phone.
i have full bars on 3g but on 4g(LTE) i get from1 to 3 bars at most....so it looks like that this behavior is normal for Sony LOL
IMHO don't compare bars to bars. Signal bars are always a completely arbitrary representation. Instead, use the SIM status in settings or whatever other signal measuring app to see the dBm or asu. I have compared my XZ signal to Huawei Mate 9, Galaxy S5, Motorola X Style, and Motorola Nexus 6, and have had equal or greater signal (with concrete dBm numbers) compared to every one.

Your explanation makes a lot of sense, I wondered about singal being low sometime but knew the phone was still having good singal thru lte discovery app on the playstore

What phone has the best built in reception antenna?

I currently use a Poco f3 and where I live I only get 1 bar signal on and off. If I put the phone next to the window it can reach 2 bars but, it's not practical to leave it there as I cannot use it there.
So my question is this.. is there any phones with a better internal antenna for mobile signal /reception? Any studies done or antenna spec that is better than others? I'm thinking that I will buy another phone that gives that tiny bit extra boost in signal and I'll be ok.
Thoughts?

The indicator on the bar is not authoritative. That's what apps are for, which present results with actual values. However, the most important thing is the distance of the phone from the mast. You need to find a website in your region, where you can find a map of BTS with the location of transmitters of various mobile network operators. Instead of changing your phone, it will be cheaper to change your network operator if its transmitter is closer to your location.

Unfortunately I've gone down the route of changing network providers without success. All the local masts are next to each other.
I've read that internal phone antennas are different from phone to phone. Some being better than others. So I want to go down this route now, it's the easier option rather than moving home!
It definitely makes sense that a better internal antenna will make a difference. The trouble is, no manufacturer lists the specs of their internal antenna and by law they don't have to. One website claims the s22 ultra has the better internal antenna thus, giving a better signal.
I have app that monitor signal strength and I also have another spare phone (Motorola). Using the same SIM card, in the same location, using the monitoring app, the Motorola gives a slightly better signal. So it makes a difference 100%.
I can recommend you the reliability of the article from this site. It is not in English, but this should not be a problem for you.
