Reception/Signal Strength? - Xperia Z1 Q&A, Help & Troubleshooting

Hi All,
I've now had my Z1 (C6903) for five days and I love everything about the phone. It really is an amazing device, except in one area for me: reception. I've been looking at signal strength everywhere I go and it's consistently lower than my other devices on the same network. Wifi performance has already been discussed, so I will leave that alone. But cellular reception on my device seems to be pretty bad. Consistently when I'm with my wife and checking her phone (Galaxy S4) she will be on LTE and I will be on HSPA+. At work, my iPhone 5s gets an LTE signal where the Z1 only gets H+. Where the two phones both get LTE at my house, the others are 8-10 dB higher. I'm not going by signal bars, I'm going by the dB reading.
Has anyone else experienced this? I bought this for T-Mobile and it doesn't have wifi calling, of course, so when it loses signal in the middle of my building I'm really up a creek. I really, really want to keep this device! Would love to hear others' experience with the cellular reception aspect.

You need to manually enter the APN Settings for T-mobile LTE or have T-Mobile send you a configuration message with the settings which will probably be the best idea!

LTE is working fine, when I can get it. I found the correct APN settings from T-mobile's support site so that's not a big deal. The problem is that the signal isn't as strong as on my other devices. When I get LTE the speeds are fine, but usually I'm stuck on HSPA where I used to have LTE

Umghh weird... My Z1 picks up LTE even with 0 bars indicated easily... Get pretty decent speed too.. Try factory resetting or have a chat with Sony Support to see if they can suggest something.. Also try requesting a signal boosting case from these guys

Those cases are a trip - I hadn't seen those before.
Would hate do a factory reset, but I suppose it's worth a try. Good to know that typically this phone gets good signal strength for you. There is hope!

LTE Reception?

Anyone else having trouble with their LTE reception? I just came from an iPhone 5 and fortunately around me the area is kind of blanketed in LTE but I have yet to get any solid connection on the One where as with my iPhone 5 it would lock on and get great speeds. I saw the LTE on the one pop in a couple times but just for a couple secs and even once long enough to start a Speed Test but then it "lost connection" in the middle of the test. I assume a PRL update is needed or at least I'm hoping its just a PRL update.
You practically have to be making love to the tower to get 4G to connect. And yes you are not alone.

I was a bit harsh...The phone is quite capable of grabbing an LTE signal..But in fringe areas is will not hold it.It will switch back to 3G..On the sensorly App it seems anything that is 0-2 bars will grab a signal but will drop it eventually..
But man when you are in 3-4 bars in dark purple this phone flys on LTE.
I'm pulling crazy far lte speeds

Yeah I was too on my iPhone 5 - like 30mbps download and 10 upload. I'll update this post when I get another chance to test it again I went ahead and did a profile and prl update.
Sounds like location. I am in Houston and 80% of the time its on 4G, I usually get around 15 to 25 down on 4G. Indoors It stays on 4G but speed drops to around 2

This is a software decision.
For most networks, the decision to switch back to 3g would be wise. For most, LTE is blazing fast and 3g is usable. Switching back to 3g on the fringe of an LTE tower is a fine decision on say, Verizon. It also makes sense from a battery standpoint. There is no sense making the higher power LTE radio strain for a signal when there is a perfectly usable 3g one available to a lower power radio.
The problem is with Sprint, with Sprint, you want to hold onto every last drop of LTE because even the faintest, messiest, LTE signal is going to be faster than the 3g.
There will be a software update, I am fairly confident, that will change the values where the the phone gives up on LTE.

I was going to return the phone today but I'll roll the dice in hopes there is an update for this because in those "fringe" areas my Note II holds 4G and its only 2Mbps down and 1Mbps up but it's better than the 3G 28.8k it switches to..
I just hope when the area is covered by more LTE it'll even out..Happy to hear that about Houston which has more coverage that the One holds it's 4G better..This is what im banking on.

I'm smack in the middle of what is supposed to be a fairly saturated LTE area for Sprint (North Dallas, TX) and mine keeps switching between 3G and 4G with total data drops seemingly random and many times throughout the day. What's weird is often times, I'll go to use the phone and the 4G is there and 3 or more bars, and then as soon as I open an app that uses data the connection will drop. It doesn't happen every time, but way more than I can live with. I'm thinking about returning it to Sprint and going with AT&T instead. I just hate to have to hassle with it and pay more for less.

well,then i guess all I can hope for is some sort of update that helps keep 4G connected
Probably has to do with a minimum signal strength value to keep it connected to LTE and not search for a stronger signal. Hopefully there will be an update or a patch to fix this.

I just feel like not enough people are complaining about this issue and it'll just keep working the way it is now. Which would suck.
Through out my searched for the night I ended up at a tmobile website where they too were having the same 4G issues.. Maybe it is a design problem and not just software.

That's helpful...with issues like this, especially at or near launch of a new device, it's always a question of device vs. network vs. software issues. I'm always skeptical that the device is the issue, especially on flagship models. I posted on a Sprint forum and one user said he took his phone back and Sprint swapped it for another HTC One and he's had no issues. Says he thinks it's some type of provisioning issue, which I am not too sure of. But he said he a similar issue with the Evo LTD (I think) and swapped and no more issues. There also was a Sprint rep that chimed in on the thread and advised me that an Vision upgrade had been made in my area yesterday and to update profile and prl and then power down for 3-5 minutes. I followed that advice but I'm still having issues. For reference, I'm in 75240 zip code.

Yeah, I think most of us that have been around a while realize that. I could care less about the bars. Hell, I hardly even talk on the phone. What I need is Data to work, consistently. I don't even care if it's 4G if a decent 3G is available and would provide a consistent connection. Well, yeah, I would prefer it be 4G. The selling point for Sprint right now is their prices and unlimited Data. When you factor in that they are really trying to upgrade their network to compete with the other big 2, and are oriented towards customer concerns at the moment, it makes them appealing. But they got to get the data consistent, especially in large markets like Dallas, TX, or they are just going to keep on churning customers. I just switched to them from Verizon as I was at the end of my contract and was a bit tired of Big Red's bullying, but I have to hand it to them, their network is fantastic. I might be going right back to them, or take a chance on AT&T, which I switched from to Verizon a couple years ago.

Galaxy S5 signal strength vs. Galaxy S4

Hey;
So I've had the S5 now for a few days and I have noticed that I don't get the same level of signal strength on my S5 that I did on my S4. Here are my details:
- Bell Mobility in Ajax, Ontario (got great LTE reception on my S4, Note 2). Wife also gets great reception on her S4 (picture attached)
- Stock roms, latest updates.
- The S5 was updated out of the box, and factory reset after the update was completed
- In the pic below, on the left is G900W8 (S5) vs i337m (S4) on the right, in my apt. I am often on HSPA when wifey is getting great reception on LTE.
- both phones' network type set to auto LTE
Is this typical of others' experiences? Or does my unit just have poor reception?

Really?? I get stronger lte signal and speeds. I'm in NY maybe thats why
Im going to hold off on buying my S5 until more people chime in on this reception issue. The S4 was adequate in reception for my needs. I was hoping the S5 would do better.
Sent from my SGH-I337M using Tapatalk
I too have noticed that side-by-side in NYC, my S4 got full bars, whereas my S5 has only 2 bars. That said, haven't noticed any difference in call quality or data speeds, despite the visual showing fewer bars. So, not sure if that means that the S5 is underperforming-but-on-par-with-the-s4, or if it's just a cosmetic glitch......
You all have to understand network technology and how it works. HSPA+ will travel further than LTE radios. That is a fact. That is why his S4 on HSPA+ has a better signal.
In the 2 days I had the S5, I found it to be on par with the iPhone 5S, maybe even better.

I don't think that's what the OP is trying to explain. He is stating while both devices are setup for LTE option, his wife's s4 is picking strong LTE while his s5 is only picking HSPA+

Ah. I misread it then (long day haha). Anyway, he might want to swap out his S5 for another and see if the issue persists. My S5 (while defective) had awesome signal strength.
Just FYI, this is probably just common sense, but I would, at all costs, avoid updating your S5's out of the box. That is, of course, if you care about getting root eventually. This isn't to say that devs won't find a way to root updated S5's just that it will be far more likely that you will be able to attain root as long as you stay on the firmware version that came out of the box.
Thanks for the replies folks.
Yes, @Matt, I am finding that my new S5 goes to HSPA in areas where I used to get strong LTE before on my old S4, and where my wife still gets strong LTE reception.
@Flashaholics: I agree with the warning about grabbing an update right away. Our device has root already via Chainfire (http://www.talkandroid.com/203271-s...st-of-devices-that-work-with-chainfires-root/) so that will be good enough for my needs when I decide that I will keep this phone or not.
Funny thing is that I have a strong LTE signal this very moment in the same location. About the same (if the pretty status bars are to be trusted) as my wife's S4 at the moment.

Same, I'm in the 845 area (orange county). I was previously holding 1 bar where I lived with continuous loss of signal completely. With my S5 I am holding a steady 3.
I have put my Sim into the S4 to check on this and my S5 is defenitely more adept at picking up the signal better.

i get phenomenal signal on my s5. granted i'm moving from an s3. but in places in my building at college that i got no signal on my s3 i get a solid 2-4 bars on the s5. this is in indy and anywhere else where i live and such i have rarely seen the signal drop below 2, its almost constantly at the top two highest bars. and the speeds are consistent and as fast as i've come to expect on lte.

I've noticed the same thing coming from my Note 2. I use to have zero signal at work, I has 1-2 bars for most of the day with the S5.
I got looks like the same signal but 3 times faster data on S5 then on S4 in Chicagoland on ATT
I found my signal bad also . thought it was the phone but after reading im not to sure?
I am in the middle of returning mine to see if I get better signal on the new one.
ill let you know.
Ok just an update my new phone has the same signal quality as my old one.
Same signal here compared to my note 2... actually even better.. I had a steady 4 bars on the n2. ..consistently getting 5 on the s5

Same signal strength issue
3 days ago I switched from the One M8 and I noticed the difference immediately. I'm having the same weak signal issue. Places where I used to have perfect signal I now have choppy calls, and laggy YouTube videos. I used to own the S4 when it came out and I don't remember having so much issues with connectivity.
Same problem here. S5 with Telus. Previously had an HTC One. At work I'm in the basement where One had 1-2 bars. S5 has 0(zero) bars no matter what I do. I do have wifi available but what should I do for text or calls? So far this is the only place I have this issue but I stay here 8h/day.
I'm thinking of returning and get an HTC M8.
Any solution to this? I really like the phone.
^ same problem here with a s5 telus unlocked.. Garbage signal strength.. I think I'm going to trade this for a Note 3..

How is signal strength?

I would love to hear your thoughts on how this phone's signal compares to your old phone? I know some people using the T-Mobile Note 4 on AT&T have reported excellent signal strength with the device. I am on AT&T, but have used T-Mobile recently with the Note 3 and S5. I have found service inside buildings poor. I am curious how this device handles that. Note 4 users on Verizon claim the signal is excellent. Would love to hear your thoughts.
I really depends where you live and work I had Verizon, At&t, Sprint and Verizon. They all varied and I have run speed test all over the country coming to the same conclusion it depends on your area. Ask your neighbors and coworkers to run speed tests that will give you the best idea on what works for you.

Fair enough. In my basement I used to get max. of 3 bars 4G hspa+....now with the N4 I get max. 4 bars LTE. (This happened after flashing my ROM.) Stock on the N4 I was getting 2-3 bars LTE.
Simple and straight up.
Hope that helps.
I'm coming from a Sony Z3 (and iPhone 5s before that) and I'm blown away with the signal strength I get with this device. I was actually talking about this with my fiance last night - comparing it to the 5s that she has currently, I was getting 4 (out of 5) bars where she was at 2.
Suppose I would need to look at hard signal strength numbers to know for sure, as it could just be software translating "more bars" where it isn't warranted. Without that though, it is noticeably better between the two devices.
T-Mobile over calculates the number of bars on their devices. What are you guys getting for the -dam value?

Yep. I had the T-Mobile Galaxy S5/Note 3, along with the AT&T S5/Note 3. I conducted a few tests of my own. Using both the T-Mobile branded S5 and Note 3 with a signal between -110dbm and -101dbm it would show 4 signal bars. The AT&T variant would show 2. On the T-Mobile S5/Note 3 for anything < -100dbm it would show the full 5 bars. This told me T-Mobile is over calculating the signal. Probably due to their high frequencies. And the fact that they want you to think you have a better signal that you really do, especially indoors.
OpenSignal shows -73/75 dbm indoors at my office.
From just using it, I consider the signal quality excellent. But I haven't tested the dbm at the other places I use it.

every carrier shows you a stronger signal than you are actually getting, so that's not unique to t mobile..
here again, the only things that actually accurately shows signal strength is your -dbm number...don't be naive and think getting 4 or 5 signal bars means you have a strong signal with ANY carrier..
-107 dbm with 4 bars here

Maybe. But I think AT&T is a little bit more accurate, versus T-Mobile. I can't speak for Verizon or Sprint since I have never used them. I have always gone by the dbm number.

Fake service? T-Mobile.

I'm not the only one getting the b.s service right? I have unlimited high speed LTE and see the image for what I get with 3~4 bars of LTE I've had this problem since my s4 and note 3 and now on note 4.
Have you tried a new SIM?
I get this sometimes too on the tower by my house. It is super fast on some towers but others have speeds like you are showing.
Yea. Sometimes it shows good reception and then I get nothing. What helped me at work is getting that signal booster. You can get it at a local T-mobile store for free. ($25 deposit? Don't remember)
This thread talks about the cell spot router and the signal booster:

Honestly, I've never had better service, however.
It's a speed test issue not a service issue. Had the same thing tried a different test and fixed it.

Not a speed test issue, I know by now T Mobile is a pretty good liar about there LTE coverage. Here's a speed test done at home the previous one was at school. Also I was a sprint member before and there 3G was quicker then T Mobile 4g ( not lte). Also if you guys flash a AOSP rom you'd see what your service signal actually is. (I'm stuck on TouchWiz because of wifi calling) I get no bars at work because of environment, can't blame T Mobile for that.
Also another noob question if I have bars but no Internet why can't I call or text? Aren't those bars for voice and text?
I take some issue with your wording of this. T-Mobile's service is not fake, and they don't lie about anything. You have to understand that EVERYTHING on a mobile device is subject to far too many factors for me to name, and everyone will have a different experience. Just because you have not had a good one doesn't make their service fake or them liars. There is no "best carrier", other than what's best for YOU. If you had a good experience with Sprint, go back to them. I hate Sprint, and I'll never have them again. I've had great experiences with T-Mobile, and it continues to get better for me under John Legere's captaincy.
Also, for the record, speedtest.net is not a definitive test.
I'm not saying sprint is better but it's ridiculous how anything but lte is good on TMOBILE most of the time 4g or edge on TMOBILE time out can't even load a simple page. They don't cover a lot of what they say on there map for LTE and most of the time I don't get speeds I'm told to get even when my phones are indicating LTE with more then enough bars. Also why do the signals change when I'm on AOSP? I get what AOSP is saying LTE speeds when indicating LTE. I don't have to do a speed test to tell me if I'm getting good Internet speeds my phone also indicates it on the top left of what it's using and sometimes LTE is really good but most of the time it's pretty unreliable and slow.
To argue T-Mobile's side. I get H+ in areas at work that my Verizon note 3, whether on Verizon or T-Mobile got no service, and it speed tests a very usable 5mbps. It will get even better with band 12 turned on.
I wish I got that, I get around 25~100 kilobytes
I never see anything above 3-8 mbps , one time i saw 20, but that was one time.
Even I get 25+ now and then but never stable and most of the time on b.s h+
Ive had the same issues but what i found is that i have to switch or force my phone to 4g for a while and then back to LTE. On LTE there are times where i will be 20+mbps down and then ill be at less than one in the same building. What i did is force it to 4g and it was actually faster. I dont know why this helps it but it has for me. I then switch back to LTE whenever i seem to remember to switch it back. I called tmobile and they had be turn off the phone for a few minutes and then turn it back on and at the time, it fixed the issue but i havent been able to get that to work any other time.
Didn't even see this when I made my thread. I've been about a month now with worthless service on T-Mobile. Whole reason I left Verizon for T-Mobile is because I got service at work where I stream Netflix, Pandora, etc. Now I can't even do that. I get H+ in my work building.
I have -58dBm signal strength usually which shows as full bars and I can't even load web pages. Get random bursts of slightly alright speeds which quickly goes away. Usually 1mbps down. Was getting 5-6mbps down. Now I really get .18 Mbps down or less.
Sprint has zero signal at work but Verizon does. Pisses me off I left Verizon for T-Mobile when I don't even get the service I did anymore. They always tell me everything is fine too.

Tmobile working great here.
Yup and every time you call me "tower us being worked on" good one.
Signal at location
Attempting to run speed tests
Finally runs
You can't tell me this isn't pitiful. That is good signal. Should be able to be usable. Hell on Verizon with 3G same spot I used to be -90 and worked fine.
T-Mobile used to work here, not sure what happened.

Working great here.
I get anywhere from 25-65 down where I live with T-Mobile and I'm not in a major city what so ever

SM N950FD compatability with FIDO network.

Hi,
I bought the mentioned model online and using FIDO sim Card. I have moved from Canadian S8+. Note 8 shows data connection as "4G" (as against LTE of S8+) and I am getting 4 signal bars instead of 5. I am not noticing any signal drops or slow internet speeds though. I am just wondering if this is something i need to worry about. I still have the option to return the phone. If this is a serious issue, I would rather return the phone and buy a Canadian model. Thanks in advance for the help!

Hi, I think some (or maybe all?) of the international models simply show the 4G icon instead of the usual LTE icon that we're used to. Someone could correct me if I'm wrong but I think it's normal.
For the reception: could it just be 4 bars due to your location, or has it been consistently lower than expected in different places too? If it's persisting then you could check which bands are supported on that model versus the ones used by Fido. Might just be bad reception in your area too...hard to say.
True 4G on INT models is same as LTE. Im using same phone and network, no issues.
Can second this.
Ask your Carrier to confirm your IMEI on their end and refresh (provision) your SIM.
Before I only received 4G on my Exynos but after the refresh, I now get 4G+.

good to know that.thanks! looks like the 4g/lte icon issue is more of a cosmetic thing but doesnt really effect data speeds.
However, I am very sure signal bars a consistently lower than S8+. I hardly see Note 8 getting all bars unless I am out on roads, not the case with S8. how about you?

Thank you.I have actually called fido and the lady indeed took the imei and made me restart the phone. I am yet to see 4G+ though. Thanks again!

yeah the bars are consistently low but didn't notice any drop in quality. Funny thing is only after getting this phone I realized how rarely we use these devices for actual phone calls anymore! Today whole day I didnt get any phone call from anyone, only tons of messages on various apps. I finally had to call myself from my desk phone!

I should note, and I failed too, that I do receive 4G+ but usually in larger areas. I live in a small city of 15, 000 and sometimes catch 4G+. If I'm in a much denser populous, I always get 4G+ (except when I'm on a call; it switches to 3G or HSPA depending on which SIM is in).
Case in point, was in Toronto this past weekend and had 4G+ all weekend long.

Same
Hi,
I am facing the same issue. Phone only shows 4 G + Reception Signal is weak
When I use 3G APN signal is stronger. Can you please share APN Settings you used
Thanks
