z3c reception issues. - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi all,
I'm experiencing crappy reception on z3c where as nexus 5 has more bars / faster coonection. The issue mostly happens in metro / subway. any radio fix for that?

are you on lollipop?

Well if the issue is when you are in the subway, there is not much you can do to fix that.
the Nexus 5 probably has a better network receiver in it allowing it to get great reception basically anywhere, whereas with the Z3C, although it does have a good network receiver, it doesn't have a good enough one to get good reception when underground

Use 2G only. That might solve the problem :/ settings>more>mobile networks> network type (GSM only)
This means 3G will be disabled

Signal Booster

How can increase my signals. I'm using ICS

Switch to Verizon. *cough*cough*
Make sure your PRL and radio are the latest versions. And if all else fails you could try Googling an Airave machine.

Could try flashing another radio some people have better reception on older radios.
Just and fyi radios are not rom dependant just make sure its compatible with your phone model

are we talking fm radio? sry for stupid question...
Not FM or AM radio - we are talking about the firmware that runs your phone's radio antennae which responsible for cellular reception
get rom manager and go to peter alphonso's thread. He's got all the radios in there....and no, this is not a radio, like an fm radio. this is the driver that provides the signal for your phone's reception...it's just called a radio. You may hear it referred to as a baseband occasionally, as well.
Some of the nexus 3g/4g users use something called Airave from sprint , it supposed to increase your signal strength pretty good. Hook it up in the home & you'll get some good signal. I don't have one atm. Some of the user called sprint saying their signal suck & so why pay for something you can't use, as in weak signal. So then the nexus user got theirs free. I'm not really sure if theres a charge to it or what, but I don't mind calling some time soon to get me one. Lol, my signal sucks as well & I'm on the latest radio, etc.
I think he is referring to this phone having a weak signal all around. I have the same issue. I had a Samsung Moment b4 the NS4G and when I sit in my living room, I used to get full 3g and full wifi with the Moment... but with the NS4G, I get almost half wifi and 3g goes from half to 3/4 on the signal meter. There are postings online reporting that Samsung used an under powered chipset for this phone, in order to get better battery life. I have an Airave from Sprint in my home, and it does work with the 3g signal... if I'm in the same room as the Airave, I have full 3g, but like I said b4, the signal gets real weak the further I get from it. (My wife's EVO 4G shows full wifi and 3g strength when placed next to my NS4G)
As far as I know, there is nothing we can do about the signal strength. I have tried several different roms, and many different kernels with this phone, not a single one touches the 3g or wifi signal issue.
i get great signal strenght, tmobile in nyc.
there are also some build.prop edits you can do too. anyways, heres the radio thread from the development section http://forum.xda-developers.com/showthread.php?t=1116884

Spotty 4g lte

Just got the One, coming from s2, and love this phone. However I'm on Sprint lte now, and get very spotty coverage. It constantly switches from3g to lte, sometimes no data at all.
Of course this is a sprint issue, but is there a Rom or other ticks that may help get more consistent lte connection?

Not really. I had to lave Sprint after being with them for 11 years due to my phone(s) not getting calls and poor network performance. In Dallas they really messed up big with Network Vision updates. Just my opinion.
Doesnt matter what hardware or software your on if the network is the problem your phone wont make it better.
Untill they get a handle on the system issues its not going to get better.

#Truth
I regret leaving Tmobile. But hey, I hope that with a Tri-Band LTE enabled phone...things should be better. At least in the near future.

Random question, but are you using a case on your phone? If so, what kind?
Sent from my HTCONE using Tapatalk 2
It's been going on for me since the beginning of July. It's not your phone, it's the awful network. The network has gotten so bad here, my local new station did a story on it since so many people were complaining. Normally I'm not a fan of stuff like this cause the media tends to exaggerate but in this particular case it's as bad as they say. I can have the tower in site and my phone will dump between X/1X/3G/LTE. Constant dropped calls, cutting in & out, unusable data, etc. I have been with Sprint for over 10 years & the network is literally unusable as it stands. It has been getting better over the last few weeks but it's still awful. I can understand some disruptions in service but this has been an ongoing thing for months with no end in site. Poor planning on Sprint's part. As far as LTE being spotty, until LTE gets turned on 800 it's going to be garbage. HTC one doesn't support LTE over 800 which at the moment doesn't matter since it's not on yet but I'm hoping by the Spring new hardware will be out & LTE on 800.

if your on a sense rom, ##data#, click edit, enter MSL (if you dont have it, sprint should give it to you), you will see LTE settings and LTE scan settings, (dont remember exactly what they're called) Lower both those numbers to like 30 and 5 or something like that, it will scan more often and while connected to LTE should stay connected longer on a weaker signal....there is a thread on it somewhere...

Reception/Signal Strength?

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!

AT&T signal issues

Anyone else experiencing connectivity issues as well as signal quality issues..
Confirmed with other users but they are on Sprint.

My signal is the best it's been with AT&T so far. Had a Nexus 5 and 6 on AT&T prior.
I wonder if the phone was using WiFi and LTE together because the WiFi here is slow.

I unfortunately agree with you .... To be honest it seems that the fancier and better our smartphones have gotten, the worse my AT&T reception has gotten. I complained regularly about my M8 and I'm not sure that the S6 might not be worse.
I helped my M8 by forcing 3 or even 2G where it seems the towers are better or the radio is better for non LTE ??? Not sure if we can force 3G with the s6

I have noticed it too. It happened to my note 4 after the latest update. All of a sudden I was getting weak 4g signal when I used to get lte. Then I noticed the update had changed my apn from "phone" to "next gen phone" or something like that. The "next gen phone apn" is the same as comes stock on our s6. When I manually input the old apn I find my signal gets better again on both devices. Maybe it's my imagination but I think it's worth trying.
When I was using my nexus 6 at home id get either 3 bars or none, very odd. But with this I get 2 or 3 consistently, never none so I'd say mine is much better
On LTE in the NYC area signal us better than my S5.
Yep I too am having an issue. I'm in Apex, NC. My previous phone was a HTC One X+. In my house, I had almost a full LTE signal with my X+. Now with my S6 I only get one to two bars in my house with no LTE. Even outside....
I'm reading online that all carriers are having issues with the S6.
Bars aren't always the perfect indicator of actual strength, especially across different devices. How about doing a speed test?

In terms of signal strength my signal is -113 dBm in and outside my house. Everytime I get a call now my calls drop or are static. My HTC One X+ never did that. People are asking me what kind of phone I have and telling me my new one sounds like crap.

Strangely, I'm having the dropped calls intermittently as well. Weirdly enough rebooting the phone helps
Obviously I don't want to have to reboot just to make calls
I've been experiencing signal issues as well.
recently, I noticed there is a spot that is showing up on all my pics. lens glass is clean, so it's definitely on the actual lens itself. Even more strange, around the time I noticed this, my signal quality has dropped off dramatically. I go into my basement, I lose all signal reception (this isn't a 1950's bunker. I've always had reception in my basement - cell towers are nearby).
my wife has an s6 as well, and sitting them side by side outside on my patio, her phone has significantly better signal strength. Guessing I got a lemon. New one is already on it's way.
What type of cases do you all have on these phones? I've read reviews on the aluminum cases or aluminum bumpers cutting the cell signal and GPS signal significantly.
she has a silicone spigen case. I have the spigen slim armor. Neither had aluminum. she had significantly better signal strength on her s6.
I got home last night, at this point tired of the signal issues while waiting for the replacement to arrive. when i looked at my signal, I had 2 bars of 4G. Took out the sim, popped it into my old M8, signal was 4 bars of LTE.

I've had poor signal too. By that I mean -101dbm or worse almost constantly, sometimes I will see -96, but generally its between -100 and -112dbm.
I have been on ATT in the same town for years. I have four other Android phones in my house (galaxy s3, Note 2, Lg G2, and Xperia z3), and they all get better signal strength than the S6.
I couldn't be heard on calls, so I complained to ATT and exchanged the phone. FWIW, I had (and am now on my second) 64gb gold colored s6.
I went through trouble shooting with the ATT tech services people and with the Samsung tech support people, they did all sorts of resets, and I even had me boot the phone into safe mode (from off, hold power button, then release it and hold volume down until it boots up).
I am a long time reader of XDA and am posting now because both ATT and Samsung said they had "no reports" of signal issues with the ATT S6. People with signal problems should post about it to get the word out. From what I have read, the s6 is the first or one of the first phones to feature Samsung's own cellular modem instead of Qualcomm's. Maybe its no good, hopefully its just buggy and things will get updated quick.
I was able to put my phone into Testing Mode by dialing #*#4636#*#* and change try different radio settings. The only one that improved signal was "GSM Only"
Switching to that radio setting made my signal go to -80dbm. But of course, GSM-only means 2g edge data. But for now, I am thinking about switching to it when I need to make a phone call.

Same.....
FWIW i have my s6 (g920I) sitting here with one bar of LTE but under settings/About/status it is showing that my LTE is fluctuating between -109 and -112 db....On my wife's M9 it is showing 3 bars of LTE but under the settings her signal is actually worse than mine at -116 to -119 db....so it seems like the reception is better on the S6 but the bar display may be off...
I just switched from a Nokia Lumia 830 Windows Phone. I had a S4 and S4 Active before that. We just bought a new house, I work from home in a basement office. I had issues with calls dropping and failing to ring. Texts not coming through until I went upstairs, etc. The Lumia seemed slightly better. I've only had the S6 for a few days but I haven't dropped a call yet, and calls connect on the first dial, not third. Both phones show 1 bar of LTE. I was worried the metal would have issues ala iPhone 4. But not only is it more reliable the call quality seems better. I thought HD voice only applied to mobile to mobile, but toll free calls for conference calls sounds noticebly better on the S6 vs the Lumia and S4.
I still think a microcell would be nice, but way too expensive. Any suggestions on finding one cheap? I thought if I complained enough to AT&T with dropped and failed calls to prove the issue they would offer one. Buy 6 months and as many calls later, no luck.

I have exactly same issue, but I'm using S6 Active.
Phone call drops everyday, I already requested a replacement, but I'm afraid it will be the same.
Oh, almost forgot to mention, my wife is using a unlocked T-mobile version S6 on my plan, and her signal is much better than mine.

3G and 4G Reception

Hey guys
I'm currently in the possession of the OnePlus 5 and this phone has a bad 3G reception in germany. On 3G the data often has some dropouts which is very annoying (take a look at https://forum.xda-developers.com/oneplus-5/how-to/oneplus-5-issue-h-network-t3658071)
I'm thinking about changing to the Mi 9 and i want to know about the 3G reception of this phone.
Does this phone has any problems or dropouts?
Nope, but i'm in UK!!!!

That's a very hard question to answer, since various telecom operators may give different results.
I did not have troubles like that with my OP3 (in HK), and I moved since to Switzerland, and was using an OP6 until recently (gave it to my wife), now I use the Mi9 and the reception quality seems about the same with the same SIM card, going to the same places, etc.
I never experienced the data connection cut so it's hard to be 100% sure...
