Signal strength issue

Hi,
I have 3g connection (airtel India) and has been adviced to use wcdma only. I observed that the network signal strenght is very low in one of the room in my house and data network also had dissapeared.
I changed the data network to wcdma/GSM mode and not only did the 'edge' connection pick up but also signal strength increased to 3 bars. I got full strength when I switched to gsm only mode.
Every time I switched to wcdma mode signal strength drops almost to zero. This doesn't happen @ my office where I get strong signal.
Is this a known issue or should I get my phone diagnosed?
I am using unrooted phone with latest stock rom ddlb2.

though i have not tested, but when > 1lac download and still 4.7 Ranking, might have something.

Hi Richy,
Thanks....but what I fail to understand is why there is change in signal strength when I change data network mode. See images..

Already Richy told you
At your Home 3G reception is poor, device gives priority to 3G, when it is available, N you have configure device mode to Auto, it try to join 3G network, when it fails it joint 2G network, as 2G reception to your home will be stonger.
There are different cell tower for 2G n 3G. N simply your home is in such area where 3G reception poor, 2G is strong.

Simply put it mate, you can't do anything on that anymore.. It is your carrier's (AIRTEL)'s downside on not delivering true 3G on your place.
The best thing you can do is to go somewhere else (apart from your home) where true 3G and signal strength is best and without any issue at all and try to connect to the internet.

Thanks to all....much relieved.
Infact I visited service center near my home today evening. Was difficult to explain to the front office girl that my phone had radio (antenna) issue, while the signal was showing all 4 bars lighted.
Came back dissapointed when I was told it may take minimum 3 hrs to run diagnostics ....I couldn't part my phone immediately, what with my corporate mail configured..
And posted this in XDA......

Dear Naveen,
Any update for your problem? The GT-N7000 bought by my dad last week also has reception issue, thought only in office! And he is on Vodafone. Just wanted to know if this is a generic issue or not. Again, it doesn't happen all the time, only when he is in office and certain times when he is on road.

No issues, understood it was weak 3G inside house. Now made it a practice to be on 2G always and switch to 3G only while browsing or streaming videos (watching IPL live).

mobile data gets shut down while on call

good evening/morning/afternoon (depends on where you read this) XDA
today i present you my strange situation:
my N7000 drops the mobile data connection every time i'm on a voice call.
it holds on for a few minutes at best then it simply drops it down until the call ends.
after the call i have great troubles connecting at 3G speeds and mobile data shows only the E for EDGE.

Hello, we got a Q+A section for these questons
Not all mobile operators allow for simultaineously voice+data, check with your operator.

It is normal for data (edge not 3g) to get disconnected while in call..
From your explanation it looks like you're set in auto mode that switches between 2g and 3g based on network ..
Instead just switch over to 3g only
If you're on a 3g plan simply set to wcdma only under network settings

i dropped a message on my carrier support forum hoping for an explaination as i read through the ToS of my carrier and they state very clearly that i'm allowed to have internet and voice call at the same time.
more about the theme: until now i always had internet and voice calls at the same time with my Nexus S even on Edge and without any drops..
ATM i'm on a Paranoid android rom and can't find any setting about 2/3 g mode selector, just a checkbox saying use 2G only, wich is currently not checked:

Sadly PA doesn't have a used selectible option for choosing 3g only under settings .
Use this app to select wcdma only

This may be irrelevant, but I had noticed it long back when I used to use a galaxy ace.
Relevant points : I stay in mumbai (india) and use vodafone EDGE (2G)
When I used to make a call, the EDGE connection used to always disconnect, however, whenever I had to use my gf's nokia E63, the EDGE use to stay on while on an active voice call. Now I dont quite remember what settings I had kept i.e 2g/3g or 2g only & gsm/wcdma or gsm only.
I used to think it was a samsung thing. As I had noticed a similar event occuring when I used another network (reliance GSM)

Worse wakelock on HSPA than on LTE. Anybody else?

I noticed that if I force HSPA rather than letting it use LTE, my idle drain is noticeably higher. So I did an experiment with better battery stats, and sure enough I get 2-3 times more wakelock in HSPA than in LTE. See attached screenshots. First is LTE, second is HSPA.
I ran the experiment several times and the results were always the same. I even did overnight tests (9 hours) and results were same, with LTE always being around 5% wakelock and HSPA as high as 15%.
Phone was in exact same place and under exact same conditions for all tests. Signal strength is actually BETTER for HSPA than for LTE, so that's not the problem.
For what it's worth, on Wi-Fi wakelock is even lower, down to 2%.
Anybody else? Any thoughts?

The results might technically be correct, but the impact seems negligible. In both cases battery charge is still 100% according to your screenshots.
Would be interesting to see this test to cover say 24 hours at least, but I'm not sure you can stand not to touch your Z3C that long

It's not negligible though. The reason I did the test in the first place was because I noticed faster drain over the course of a day or two on HSPA versus LTE. The test revealed that my perception of faster drain was likely correct given that HSPA has 2x to 3x as much wakelock time.
So yes over 3 hours maybe no noticeable increase in battery drain, but over 24 or 48 hours it was noticeable in real life.

Probably due to this issue which plagues Sony phones. I've had the Z, Z1, Z2 and now Z3C and they all suffer from this. It can only be fixed if you have root access.

I'll be interesting to get that a bit more quantified over a longer duration/period of time in order to really judge the impact. Anyhow, I do not see this behaviour on my Z3C and battery goes down by just about 1% in say 10 hours.
Conditions:
- connected to 3G/HSPA network with mobile data off,
- BT on (never turn it off),
- WiFi off,
- FW: .98 DE (what is yours, BTW?).

I'm on the .93 firmware. I might flash UK .105 this weekend and compare.
Btw, if you turn mobile data off, doesn't that effectively disconnect you from HSPA? I think you need to leave it on.

No, not that I'm aware of. Why would it disconnect from the HSPA/3G network just because one turns mobile data off?! Further, you can check this on the status page of your phone, my one does not switch networks while turning on/off mobile data.

Because HSPA/3g IS mobile data.
I don't think the status page is very helpful either. It shows what network you are supposedly connected to even when you are on WiFi, even though on WiFi you are not really connected to mobile data, either.

Ok, we're going to mix things up now. Disabling mobile data does not mean you're not connected to a 2G or 3G network. So, even if you're using WiFi, the phone remains connected. How would you be able to place/receive calls otherwise?!

Calls are not placed placed over the HSPA/3g networks. They ate placed over the 1g networks I believe. (Until voLTE at least).
Sent from my D5803

In other words, you can disable 3g/4g/LTE and whatever else and you can still make and receive calls and sms because they don't go over what we typically consider the data networks. That's also why calls work even when your APN settings are wrong.
But I'm no expert. That's just been my understanding for the last several years.

No and no. Calls are placed over the 2G and the 3G networks, some providers even via LTE (VoLTE) now. There're are no more 1G (analogue) networks anymore since years. So today it all starts with 2G.

You're again mixing and confusing two things over here. A mobile network (no matter the generation) can (and is) used for a.) voice and b.) data. No such thing like an exclusive mobile "data network" anywhere. APN stands for Access Point Name which is the name of the Gateway between a Backbone of a mobile network (e.g. 2G, 3G, 4G) and an external packet-based data network, that is the Internet.
Please, make yourself a little bit more acquainted with mobile networks and the terminology first and then come back on the core problem, if there still really is one.

There is one. See screenshots above. Everything you said in your post is irrelevant to my original post, even if true. Hspa has higher wake locks than lte by 2x or 3x.

[Q] flash LYZ28E on Verizon N6?

I am using Verizon N6 on Tmobile and was wondering if I can flash the TMo ( LYZ28E ) on my phone to get wifi calling on Tmo.
Can somebody please confirm?

Update: I was able to flash LYZ288 TMo build on my Verizon N6 using nexus tool kit without any errors.
I can see Wifi calling option in the settings options now and I need to figure out how to test wifi calling actually works on the phone. Any suggestions?

the WiFi calling will only work if your provider provides support for WiFi calling, and Verizon does not. only tmobile will provide support for WiFi calling, and the fi network.

Provider of the phone or provider of the Sim? I'm using T-Mobile sim

Funny T-Mobile tech support won't even answer any of my questions because I brought the Nexus 6 over from Verizon. I can't get Wifi Calling working even though I am on the latest TMobile OTA. They claim they cannot provide support to devices not bought from T-Mobile. I'm currently stuck digging through XDA for a solution to my problem.

Question 5G always on battery usage?

Hi everyone, was wondering if anyone know how much more Battery usage does having 5G toggle turned on uses compared to having 4g/3g only.
The reason im asking is that VoLTE doesn't seem to turn on when I don't have 5G turned on. I dont turn on 5G because there's no 5G in my city.
Please help

Lots more for me using it on TMobile USA.

Yes, 5G does drain a lot more battery. VoLTE would work even if the device is on 4G/3G option but honestly there isn't much of a call quality difference with or without VoLTE. What really makes the difference in the call quality is wifi calling...turn that on and you will notice a marked difference in the sound quality at both ends of the call.
5G is not practical unless there's great coverage. I live in a very well covered 5G area but unless you are constantly browsing/ on youtube, the phone doesn't bother using the 5G band. So, let's say the phone's screen is switched off..you will still get your messages but on 4g band. I think it's something to do with the kernel that puts the phone on 4g when the screen's off...probably to save battery. The moment you switch on the screen, you'll see the network change to 5G...
I don't use the 5G unless I really need to say like downloading a huge update when the wifi is clogged...
TLR: There's no point in activating 5G unless there's a real need for speed and that you're in a good 5G coverage area.

Unfortunately, mobile data does not work automatically if the 5g toggle is off. I have to manually put the phone on airplane mode or restart it for it to work. Such a big hassle.

Someone did report that issue with the last firmware update and apparently, the latest update has fixed it. You could try a Bixby routine to turn mobile data on when wifi is off as a temp solution

I know exactly what you mean. You'd expect that it would connect to VoLTE but it doesn't. The only time it would connect is when I got the 5G toggle on.
I have tried it with multiple sim cards/networks and it only does it with my current provider - Vodafone. It is bizarre, i know but i can prove it with screenshots
