Random call drops - Xperia Z2 Q&A, Help & Troubleshooting

I have problem with my Xperia Z2, almost every time I'm on a call with someone I get random call drops.
The cellular signal is full. I don't know what it can be.
The phone firmware is 17.1.A.2.55 (stock) and it says that the phone has the latest updates. (T-Mobile)
Anyone experienced this problem?
Is this hardware or software problem?

It could be anything, but I would first start with your carrier or who you bought the phone from.
Do the drop outs happen anywhere or typically in your house or local area? Maybe your local area just has poor coverage on your current provider?

The call drops happen anywhere.
Like I said, the cellular signal is full, but the drop occurs.

Same happens to me. I figured it out. The screen is still on although your on a call and it seems off. So if your lips touch the end call button it will obviously end

do you sometimes find that you are in different menu's too when you end a call?
you could be pressing buttons while on the phone
there is a few with this problem
for some reason when on a call you can press buttons with the side of your face and even cut people off! I have put mine in to airplane mode turned wifi, bluetooth and location on and all sorts of things
all this is with the proximity sensor covered and screen blank!

Never in a different menu.
I'll try to speak on a speaker phone and see if the call will drop.
If not, than maybe its the proximity sensor.

Dropped calls and digital static?

Has anyone else had frequently dropped calls even when you have 3 or more bars of service? Also, my wife says that she often hears an echo or a "digital " static while talking to me. I have made many calls from all the same places with my old iPhone with no trouble.
I am loving this phone in every other way, but this is still a phone after all
I would hate to have to go back to an iPhone!
I am having the same issues. The static only seems to happen while using a bluetooth headset. I've only had dropped calls happen in my local area. Since this is where I use the phone the most, it's an obvious problem. I tested this with my Captivate and no dropped call. I am returning my SGS2 for a new one. The store was thinking it might have an antenna problem. I did notice that side by side against my Cap the SGS2 was getting much better reception. Standing still the Cap had a signal of -95, the SGS2 had -77. This is a very big difference. So I really don't think it's an antenna problem but I'm willing to try it rather than give up on it. If this doesn't work I'll return it and wait until new modems start hitting the forum.
Possible fix for dropped calls
Update to yesterdays post. I did return my SGS2 and received a new phone and sim card. There was one area in particular where my ability to make a phone call was near impossible. My Capitivate had no trouble here so I was annoyed. The new phone had some improvement but still not great. Later in the day on the way to bringing my son to Best Buy the phone was back to terrible. If I had had my box and receipt with me, I would've returned it right there. I told the cellular manager about my call issue. She told me to turn off 4G if possible. I don't have a toggle for 4G/3G so I just turned off the data. That solved my problem! I called someone to stay on the phone while driving through the effected area. There was a small span of about 30 seconds where he said my call was getting garbled but the call didn't drop. Before turning off the data it would have dropped numerous times by then.
If you're having call trouble, it's worth a shot.

[Q] issues with headphone jack, mobile network connection, and mms

I've had the amaze for two weeks now and for the most part love it aside from a few nagging issues.
1) Headphone jack is sensitive to movement (music will cut in and out sometimes if i am walking with it in my pocket)
2) Can't receive pictures. (I've set up my mms to have a max size of 3500k but still not able to receive anything)
3) My signal will cut out randomly for minutes randomly even in places that i usually have full bars. It doesn't just say no signal but my "mobile network" option says its off and its greyed out so i can't try to turn it back on.
Any one else having these issues or have any suggestions? thanks.

I have issue 3 sometimes. No solution yet.
Sent from my Dell Streak 7 using xda premium
Update.
1) The headphone issue of the sound cutting in and out only occurs with some headphones, so I'll just need to find a pair that work fit perfectly I guess. But it made still need to be fixed by sending it in.
2) After calling in, Telus tech support were able to work there magic and fixed the MMS problem. They said it sometimes happens when a new phone is just activated.
3) As for the signal, I found out that these new 3g, 4g phones only use the HSPA+ networks and cannot use the 2g (CDMA/ GSM) network to save battery. The 2g option is there to be used when roaming they said. That doesn't solve the random loss of signal but it has occurred for a while now so hopefully it won't happen much more. Hope this helps anyone else that might be having the same issues.
The only issue I have is the case that Tmobile provided, the hole for a typical headset and power/usb was too small.
I ended up getting the ibeats from beatsaudi. Sound awesome and fit fine, the only issue I'm having with those is the buttons for vol up/down/call dont work due to the fact thats its made for iphone. But other than that their awesome.
Maybe i'll try those on for size. Hopefully i'll find some cheaper ones that work though in the meantime because those aren't cheap.
Bose on ear headphones are amazing.

Amazing as in amazingly bad for the price. I'd Recommend AKG or Sennheiser. Failing that even some V-Moda's would be a good deal. Personally I use Custom made triple driver In Ear Monitors, and the Amaze, with the DSP running, is extremely good indeed soundwise. FAR better than the Ipod Touch I sold.

SECOND UPDATE
Turns out my headphone jack was defected, so I exchanged it for a new amaze, and so far so good.
As for the network connectivity, for TELUS users we don't have the option of 2g, so when I had the settings as wcdma/gsm my guess is the phone was trying to connect to the gsm network but when it couldn't connect it left my phone unconnected to any network. So far with the settings as wcdma only I haven't had any issues. I will see if this will stand the test of time.
I am having 2 of the problems you listed.
On the bus this morning, not only was it cutting out, but completely disconnecting and stopping the playback. As i put my hand in my pocket, I hit the play button and offensively heavy drum n bass started blasting. So good external speaker from what I can tell
I find I will have full coverage, and my texts will not go through. I will try out wcdma only and see if that helps.
I haven't tried receiving picture messages yet... :/
I guess I will pop by Wind on my lunch break and see if the headphone jack problem happens on another phone.
Make that all 3 issues :/

definitely take it in sooner than later to see about the headphone jack, because although they don't always advertise most companies have a 30 day grace period where you can just trade it in the store for a new one instead of shipping it off and waiting weeks for htc to look at it.
Some people say that some phones are just going to be defected since they are so new, so hopefully if you swap it the new one will work good like mine did.
Ask the tech person to do some initialization for your phone that should be able to receive mms afterwards.
As for the connectivity mine still loses signals from now and then, I guess i'll just have to live with it for now and avoid those areas as much as possible. Good luck
I tried the headphones that came with the phone and they work fine, so I guess I just have to be careful which headphones I use, and try out any before I buy them.
I went in to ask about the MMS, and learned my "unlimited everything" plan didn't have MMS... odd. I should still receive them when someone sends them, and I don't. They told me to go to another location *sigh*.
Update on the loss of signal problem, it only happens when I'm in my basement. I had someone call me while I had 3 bars, and I got a text saying I was about to have roaming charges. I think this has more to do with my provider than the phone. To combat this, I'm just going to leave my phone upstairs and access it from my laptop when I'm in the basement. I'm having problems rooting my phone, though... but that's for a different thread.

[Q] wifi network order, priority list, etc any way to set the order?

How do you set wifi priority, so it'll stay on the one i want it to connect to, not the strongest, or first one it saw, etc etc. can i order the 'saved' networks in any kind of priority list?
anyone know?
If you look at wpa_supplicant.conf over /data/misc/wifi the networks have some kind of priority there.
I don't know how this works, but just give it a try. Try to change the value from each network to find if it gives priority for the highest or lowest value.
---------- Post added at 06:07 PM ---------- Previous post was at 06:00 PM ----------
I have a issue with wifi too.
I have 4 routers at home with the same SSID to extend the wifi range.
The phone connects to the first router he see's but doesn't changes if I get closer to another router, it stays connected to the first one while it catches signal.
To change router I have to turn off wifi and then on again.
Sometimes I'm next to one router and the signal appears on minimum because it stays connected to the first router it saw.
Weird, ah??

Wireless devices "roam" from AP to AP depending on how their wireless chipset tells it to roam. Some chipsets roam aggressively (like a wireless VoIP phone), while others do not roam so aggressively (most laptops/tablets). I've seen Samsung tablets stay locked to an AP at the opposite end of a warehouse instead of switching to any of 5 closer APs with FAR great signal strength. Very annoying when it doesn't do what you want, and the wireless chip doesn't allow any configuration. I've seen other devices wait until the signal is completely dropped before switching APs (which really sucks). I wouldn't think these phone would be very aggressive so it'll stay locked to the first router as long as it's not seeing dropped packets. Sometimes a stronger signal isn't enough reason for a client to roam. When you turn it off and back on, it has to reassociate, so it will generally pick the stronger signal.
I hate this. the wifi on this is just crap. roaming is terrible, like you explain. but priority should be basic. I have a weak router I can see when on the third floor, but as soon as I'm on first or second floor, can see the fast router. I don't care how weak it is, if I see it, it should connect to that, not stay connected to the weaker 3rd floor just cuz it was the one connected to

When you go downstairs just let the phone sit for a few minutes. If you're actively passing traffic maybe the chipset won't let it roam. Wait it out and maybe it'll realize it should switch to the consistently stronger network. When I was testing this in my house with a cheapo netbook I noticed that I was a little impatient during testing, but in real world usage the slow roaming wasn't actually an issue.
When I walk around my office building and/or in our warehouse (full coverage wireless with 50+ APs) mine phone roams just fine. I'm not sure if it roams to the strongest AP everytime, but I know I always have a signal no matter where I go.
its not just the stronger network issue. 3 rd floor is a separate internet over power line,5mb max, split across about 10 devices. iron rods plus lead painted ceiling of concrete (it was an addition to an old old building) make it unable to see 1 st floor internet, which is a fiber 100mb line. both are picked up on 2nd floor, but it will latch on to that 3rd floor wireless and hang on one dot seemingly for dear life. I've tried forgetting networks and re learning them in both orders, it just some reason prefers the slow ass connection unless I remember to manually change it, even when it still connected to one dot but no internet comes.
--
then at home, now I have to deal with the wifi phantom death, so I don't even know I'm not actually connected. I swear, they sourced this wifi chip from some guy's garage company instead of a manufacturing company!
that was harsh, I actually believe its a software issue and not the chip,as it doors seem quite strong and capable. I'm just getting angry at this thing

Complaints on Call Quality

I've had the call fade in and out a bit. My spouse (has the same phone), noticed people complaining about fade out during calls, too. We noticed that if we held the phone normally (fingers wrapped around the phone, about the middle of the phone), the calls fade out. If you hold the phone around the bottom near the speaker -- or use a headset -- calls are okay.
As a little test, I held the phone normally and the network signal was around -114 dBM.
I put the phone on the table, the network signal was around -104 dBM.
Both our G3s exhibited this issue. We didn't purchase them together, either (one by mail, other from store). Perhaps its a phone issue, perhaps we coincidentally received bad phones.

I think there are more than just a few people with this problem. Mine is giving me the same issue. People tell me they can't hear me at all, or I sound like I am stuck in a well, or that I am ignoring them. I've tried a couple of things but to no avail. I believe it has something to do with noise cancellation. I just turned off voice enhancement and voice privacy and it still seems to give me this problem but I am gonna try it out for longer. I am with Verizon. Let me know if you guys have any ideas.
Yes I have noticed that when the phone is right to me ear im ok but a couple of inches away and people say echo or sounds like Im stuck in a wall. I mean weird? has anyone tried a factory reset
I've been struggling with this issue since I purchased the phone on the 17th. I've also noted significantly worse signal in relation to my G2. I swapped out my phone this past weekend and the problem exists with the replacement.

We had this problem with the Verizon g2 when it first came out. Tried swapping devices, Sims, and nothing worked. Eventually LG updated the radio which fixed the issue (if I remember correctly).

In vehicle bluetooth works every time. I had one case where my wife could barely hear me through the phone (we both have the g3) but all other calls have been fine thus far. Hopefully this gets addressed in the first update.
Still An Issue...
Any update on a fix for this?
I just spent a month calling VZ about how people have trouble hearing us (we have two G3s with the same problem). One was replaced and people still have trouble hearing us.
The SG3 was never this bad with calls.
I have not tried my G3 with the Prius Bluetooth, but on every call so far over Verizon or Google Voice/Hangouts the Voice quality whenever I enquired has been reported to be fine.
The only issue I have noticed is that sometimes when I hold the phone right-handed my finger underneath it covers the Mic hole.
Sent from my VS985 4G using Tapatalk
I have a bad habit of bringing the mic away from my mouth at about a 45 degree angle while keeping the phone to my ear. When I do this, I get reports of the echo / can't hear me. Bringing it back to the proper position seems to correct the issue.
I have an ad hoc solution that seems to work so far:
Use the speakerphone while on the call. Totally obnoxious in social settings, but if you're somewhere private, it works.
Turn off Bluetooth. I did this a couple of time no one complained not being able to hear me.
Speaking to Verizon is pretty much useless. One rep did a fancy dance to say this is a software issue and they can't do anything for me at this point.
Add me to the list of Verizon LG G3 owners with poor call quality. You guys have described exactly what I am experiencing. People tell me I fade out, sound tinny, sound underwater etc. I have tried the phone in a case (OtterBox) no case, different parts of my house, different positions holding it, making sure I'm not covering the mic etc.
Also did a factory reset and ran the phone in "Safe Mode" as well
Same problems. Seems to happen on longer calls BTW and I have no troubles hearing people.
I am getting a solid -104 to -108 LTE signal and solid -89dbm CDMA and -88dbm 1xRTT signal.
Right now I am going to use BT exclusively and see what happens, but this is troubling since I make a lot of calls.
I never had this problem, in the same location my house, with my last phone a Droid Razr Maxx.
It gets pretty much the same signal levels.
Any ideas on this?
Is it a Verizon problem?
I bought this phone in BestBuy so I'm not really sure how to proceed to exchange it as I am past my 30 days?
Do I call Verizon?
Go back to Best Buy?
Call LG?
I've dealt with Verizon before and like the other person said, it's not a pleasant experience .
Help!
P.S Other than the call quality issue, this phone is incredible and I love it.

I have the same problem as many on here and it's frustrating. As great as the features on the phone are, it fails at its most basic task - making calls.
I quoted you to answer part of your question. I, too, got my G3 at Best Buy - 22 days ago to be precise. I finally got fed up with the call quality problem and spoke to Best Buy yesterday (and had the issue pop up mid call with them). Unfortunately, their return policy is 15 days. Beyond that you're forced to use a protection plan claim, if you have one, or work directly with LG for a repair - which would leave you without a phone for a few weeks while LG does its thing. It was also suggested that it could indeed be a software issue and a future update could fix the issue. But that does nothing for us now.

Thanks for the info Rodeojones.
I suspect it is a software bug.
I "think" I can still take out a protection plan with Verizon so I might do that just in case it gets worse.
I'm trying the BT headset exclusively now to see if that helps or changes things. So far nobody is complaining and also when I use the BT in my car, a crappy Jabra Freeway Speaker thing, nobody seems to complain either which leads me to believe that maybe the mic is doing something odd causing the phone to reduce the audio going out or something.
It certainly is disappointing having a top tier phone that has problems making phone calls.
@stang2003
You've described all the troubleshooting steps I've gone through as well. I am disappointed beyond words. I would at least be happy if there was some affirmation from Verizon or LG that this problem exists, but I'm not going to hold my breath waiting for it....

From what I am reading it seems this might be related to Verizon only.
Is anyone having these kinds of problems on a different carrier than Verizon?
I did find a number of threads regarding poor signal strength with the G3. Seems even the EU folks are having these problems.
Maybe both call quality/microphone problems are actually related to a poor radio signal?
Ok, so an entire day using my Blue Ant ancient T1 BT and not a single complaint about fading in and out etc. In fact I was talking to a person on BT and it was fine. I disconnected the BT, did not move the phone which was right in front of me, put it on speaker and within a couple of minutes he was claiming he couldn't hear me, fading in and out etc. I switched to regular ear (no speaker phone) and same thing with fading in and out. I went back to BT and talked for about 10 additional minutes and it was fine.
My preliminary conclusion, and it's really too early to tell, is that it's somehow related to the mic in the phone as BT doesn't seem to have the problem.
Can anyone else confirm this?
Test with BT and see if you get complaints from people on the other end that you are fading etc.

LG G5 network problems after attempting GPS fix - only 4G/3G - no 2G signal

As the title goes I tried to make a GPS fix buy adding a little thin plastic under the pins showed in the video tutorial I used but after assembling back the phone noticed that I cannot connect to 2G anymore. I switch to 4G and 3G with full coverage but when I try to went back on 2G the network signal drops and phone says "Emergency calls only". I opened it again and removed the plastic board and switched it on and got slmost perfect 2G coverage but my microphone stopped working - nobody was able to hear me speaking so I opened it again and added a little card board piece on the place and now I have good mic with good 4G/3G signal but again with no 2G signal again. Can somebody tell me what I'm doing wrong ? Also where are the exact places of the 2G/3G/4G/GPS antenas ? I travel a lot on places with low 4G and even low 3G coverage so I really need the 2G mode again. Please help me fix it as it was before. I need 2G more than GPS so if somebody tell me how to reverse this would really appreciate it, thank you !

Ima follow this one closely. Mine has the very same issues ive bassicly asked the same thing
Mine does it one all three. Rarely picks up 2g gsm network gets crappy 3g and lte. I use lte discovery to verify all this. Now i have noticed that if i pinch the chin or hold the phone like laying in bed only by the chin i get killer signal and even pick up 2g at the same time as lte.
I watched other devices all get band 5 lte and gsm at the same time.
I cant find any confirmation on where the antennes are even located in this device.
Today I noticed that my sim tray stays slightly out of the phone body so I tried to push it in and it wasn't going any furder as before. So I though there must be something in the tray preventing it to push in till the end and I used a magnifyer to see inside and noticed a small plastic that seemed from the same material of the pick I used to open the phone so I got it out and now the sim tray is closing nice again and now I'm able to connect to 2G but still the reception is not good as it was and it drops from time to time... Still this is an advance in the right direction. I think I had broken or bent or moved something slightly off place from these several interventions so I'm f****d up.
Please guys don't try to make any gps fixes because you will do more harm than good ! That is my advice !
If still somebody can help me, please write ! Thank you !

Please share where the f**k is the 2g/3g/4g cellular antennas PLEASE !!!!
Nobody here is engineer at LG. And nobody here has any real solution for GPS / 2G / 3G fix. Looks like GPS breaks again even after sending it to repair. This LG G5 has been the crappiest phone I ever bought. I'll be buying a G6 soon.

As the title goes I tried to make a GPS fix buy adding a little thin plastic under the pins showed in the video tutorial I used but after assembling back the phone noticed that I cannot connect to 2G anymore. I switch to 4G and 3G with full coverage but when I try to went back on 2G the network signal drops and phone says "Emergency calls only". I opened it again and removed the plastic board and switched it on and got slmost perfect 2G coverage but my microphone stopped working - nobody was able to hear me speaking so I opened it again and added a little card board piece on the place and now I have good mic with good 4G/3G signal but again with no 2G signal again. Can somebody tell me what I'm doing wrong ? Also where are the exact places of the 2G/3G/4G/GPS antenas ? I travel a lot on places with low 4G and even low 3G coverage so I really need the 2G mode again. Please help me fix it as it was before. I need 2G more than GPS so if somebody tell me how to reverse this would really appreciate it, thank you !

The 3pins in the video are for the Volume buttons. The REAL GPS antenna are the ones next to the headphone jack.
So far I experimented that the cell antennas lies at the top of the phone since covering the top-middle section of the phone Cell signal drops.
Maybe the plastic shim you put in is too thick that it's interfere with other internal components, like the black RF antenna ribbon that runs across the top section of the G5. See if removing the plastic piece resolves the problem
Hi guys,
Just want to let you know that I gave the phone to a service and they found out that I broke some of the pins even without noticing. That is why this problem occured! They were able to replace them so now my phone is live and kicking again with full network coverage on all bands (2g,3g,4g). So happy with it ! So go ahead and bring your phones to a repair service center and make sure it will be a good one! First I went to affiliate LG service and they told me that most of the things are unrepairable and will have to change the whole motherboard which costs as a new phone so I lost any hope fixing it but later a friend of mine recommended another service where the guy told me he will inspect all the parts of the phone and will call me if he finds anything suspicious or broken. So I left the phone and after 2 days he called back and told me that 4 pins were broken and 2 more damaged and bent badly. He also told me he thinks that if we change them the problem should be solved so I agreed and he did fantastic work on the phone and now works as new !
So don't be disappointed and find a good service where they can try to help you. Also when you are doing some mods to your phones please be very careful!! I confess that I wasn't careful while doing the mod - I was at work and even didn't had the necessary tools for the task, also the colleagues were around and distracting me so I wasn't able to focus entirely on the task and did more harm than good! Good luck !
Thread may be closed, problem solved !
