[SOLVED] - Xperia Z Ultra Poor Signal Reception Indoor - Sony Xperia Z Ultra

Hello,
I have bought an used xperia ultra off the internet.
The problem is that outdoor I have no issue with my signal. But when I go inside the signal drops and it shows me NO NETWORK.
Is there any solution for this ?
Thank you in advance !
I have tried software update and hard reset with no luck ...

Depends on the type of house you're living in and the general coverage in your area. I live in a concrete apartment and i have excellent coverage, so it might be the coverage in your area? How many lines do you have when you're outside?

Now I am using my sim card in a nexus 4 and i get full signal in the same place where my xperia doesn't.
The cell tower is not very far away ...
So, the house is not a problem ...
P.s : nexus 4 has full signal on wcdma but xperia has no signal/poor signal even on edge/gprs ...
As you can see in the picture, every phone tested with that sim has full signal in the same place. But not the xperia ... I think it's "blessed" ...

Weird. I get better signal than ever with my Z Ultra. Inside on the countryside right now where my signal always was 1-2 bars with most of my other Androids and i often lost the signal temporarily. I'm sitting on full 4 bars now with my Z. Amazing!

Well you are a lucky man, congratulations. My problem is that I bought the phone in a different country and I'm pretty sure that the folks here in my country will deny the warranty ... And going back in the country of purchase is not an option.
Does anyone have a Modem/Baseband that could be flashed to see if the problem still persists?
Thank you !

Problem solved ...
For all of you that experience the same problem, take a hot air gun, heat up the back of the phone, and slowly take it off with a suction cup.
After doing that, check the cable that comes from the antenna to the motherboard. Mine was loose, and I hat to fit it back in it's correct place.
After powering on the phone, the signal is OK !
Attached a photo below:
And a video with disassembly instructions.
Hope that helps you.

Hi there - by antenna, do you mean the whitish cable on the right-most section of your picture?
Another thing, did the back cover stay attached perfectly after you've re-assembled it? I mean using the heat gun on it didn't make it permanently loose?
What about water-proofing?
Thanks!

Same here. Will this solution not affect the waterproof of the phone? Anyone has any other solutions?

Wouldn't it be easier if you just send it in to Sony?

It would be, but I bought it on ebay and I don't have receipt for it. The other thing is I noticed when the phone is in standby it has full signal when i start using it the signal bars are going down.

Hi. Finally it's working and yes the cable was loose. It's really easy to open the phone. It's the cable on right it's grey and silver ( like on picture) You can buy new original adhesive tape on ebay for £5. I don't know about waterproofness after. I will try when I will get new phone. Hopefully ultra2

I'm surprised you'd even want a new one after dealing with that. Hopefully I don't need the original receipt to get warranty service. I hate the idea of opening up a new phone to solve a problem with a home remedy. As you can tell I am suffering from the same issue.

3G and 4G can have poor reception indoors. See if switching to 2G only helps, even if you don't have mobile data enabled.

It was the only way to normally use the phone. It took 5-10 min and now it's working perfect. Try with Sony service centre, I hope they will do it for you. It's best phone ever, I hope they will make ultra 2.

I have exactly the same issue

aaand now I have the same issue. ****ING hell...*****phone ...eh gonna send it in someday next week. I don't have the receipt here so got to go to my other apartment first

a weird solution that worked for me
Hi guys I had the same issue and solved it finally
First I tried your method and checked the antenna cable mine was already in place and fine so I was depressed and closed the phone back.I tried every thing else rebooting,repairing through companion,updating the rom, changing sim, changing network and every thing else. Finally I took phone into service they returned it without the issue and I was pleased too much, but same issue returned after 2 weeks
So I tried a stupid thing that worked like a charm I put 2 pieces of paper under the sim and above the sim metal holder and inserted the sim back then the issue was solved and network is like any other phone finally
It worked for me and I think it may worse a try

Mindgasm
I Just bought my New Z ultra Last month. At beginning i thought that my Z ultra poor signal were normal (90-110 dbm) until I compare to my friend's Z ultra. I realized there's something wrong! I was hopeless till I found this thread. Thanks to Al3xxxinho it worked! The antennA were loose also. Easy to open and I didnt see it Will break the warranty seal if you open, and the back cover still fit perfectly. Now I enjoy full signal bar. :laugh::laugh::laugh:

What I did was chanel the preferred network type to wcdma

Antenna Mod [Fix]

[Fix] I accidentally messed up my signal by pushing the little button on the lower right side of the battery. don't do this I could only achieve EDGE after, if that. so what I did is use a 4 inch copper wire and electrical tape. place one end of the copper wire in the little hole(it's a part of the antenna receiver group) and use a thin piece of electrical tape to tape it up the back side by the battery. now I have a better signal then before. I recommend not doing this if your signal is still working. Do not me if you mess it up, this should only be a fix if you need it.

Dudeeeeeeeeeee! I got this very late. Last week my phone went off without notice at all, so, trying to make it come back I pressed this litle thing thinking it was a kind of hardware reset switch... Anyways, my cell came to live after 3 days, at least accepting my ON command and showing low battery (this is another issue) but now the signal reception is real poor (only 2 bars -105 dBm 4 asu) and yes...now I know that I have screwed it... Let me try your approach with the cooper wire.
Thanks
Guys be VERY CAREFULL as that to me looks like a port for an external aerial. if you short the iner pin with the outer sheild you could do some real damage to your phones transmiters/recevers
Also another thing to take into consideration is that aerial are a certain length to what freqs they work at
ie the FM areial in your car is shorter than the AM aerial, and the digital one is shorter again.
There is so much theory behind aerials that it is not funny! (im a comms tech by trade)
Just PLEASE be carefull guys!

Guys I am having the same problem of low signal at various locations. Pls do let me know if it is advisable for putting a jumper of copper wire as described.
Do I need to solder it with the hole ?
Will I loose my network permanently ?
Up to you
I would advise trying a different carrier or ask someone with the same phone/carrier how their signal is. I would only use these methods for emergencies like my situation, or like the other where he had next to no signal where he lived. As for soldering, i never thought of it, i revised my method, which i should post screen shots, by placing a larger wire in the hole and using a glue gun to hold it in place. I take no responsibility for antenna loss, because once you shove something in there, you won't have a signal unless something is in there. Good luck, i hope you figure out what's best for you and don't forget to post your results =D

Thx.. but same situation as yours the signal keeps fluctuationg n sometimes no signal so its kind no-no use sometimes or bad signal.
So I was thinking of putting a copper wire as suggested and checking it out.
As you mentioned like in near future if the wire breaks or think of removing it, I wont be able to get any signal in furture ..
Do you suggest replacing the antena & what would be its cost ?

Send it in, if it's under warranty . If it's just an old phone you have, and you still want to use it, by all means ty it out, i guarantee a better signal as long as you use a long enough wire. When i switched to a thicker one, i got a better signal, but the battery cover doesn't close all the way, but that doesn't matter since i use a case and i don't notice it.

Well funny story really, i ride a motorbike to work and back each day and i have my phone in my jacket pocket as i use it as a mp3 player and listen to music while im riding, basically i was going down a private road at high speed and my music stopped i looked down felt my pockets and swore rather loudly. Turned around and after about 5 mins found the phone and its case, (still missing my sd card and battery,, it was about midnight) went back the following day and found the sd card and battery, unfortunately the screen was smashed and the lcd was also cracked it powered up but there was no picture, i have noticed after further examination that along the bottom of the handset on the back just above the charging port there is a crack in the plastic and a bit is missing and you can see two springed metal connectore, now whether these connect to the antenna for network or not i do not know, ive been googling non stop and the general idea seems to be imei problems??

Mobo could be damaged. Either that or the antenna is missing. The antennas are located on the right and top of the moon. It is exposed when you change the LCD. If you switched it yourself, check those connections. It's pretty easy to check it.
Right and top of the moon? Also the phone works perfectly if not faster than it used to wifi Bluetooth etc all works is the antenna with the wire that runs down the right anything to do with it ?

LG G2 Fix Bad GPS - Cell Phone Signal in 2-5 min

Due to the many problems with cell phone signal and gps on LG G2, i will show you how to boost your gps and cell phone signal. It's seems to be a manifacture's defect, once you open the back cover and then close it, you can face this problem!
Speaking from Personal expirience
In order to fix this issue, please watch my guide below:

Man I hope this works! I never had a problem with my GPS until recently. I upgraded to Lollipop and within a 2 days period replaced my LCD./digitizer/frame.
Now I constantly get "GPS signal lost" while navigating. I'll be giving this a shot and will report back after using navigation a few times. I'll know right away if your fix works.

Well I tried your fix and I'm very happy to say my GPS has been working flawlessly ever since! Almost instant lock and no more "GPS signal lost" crap. I used a slightly different method (Bondic liquid plastic, Google it, it's awesome!) to elevate the connections on the back cover but it worked and I'm stoked! Thanks for the fix man!

This worked for me for a while, but not for more than a few days. I've now tried a drip of solder on the copper contacts on the back cover, which has been better, but that too has since degraded.
Is this still working for you a week later?

I did this fix 5 days ago and my GPS has been working flawlessly ever since. As you can see in the screenshots i took just a few minutes ago my time to first fix was 1 second, and 13 seconds. That's about as good as it's gonna get!

I don't think this fix works on VS980.
Tried this fix with an old credit card a couple of months ago and it definitely works.
My initial attempt was using a bit of cardboard but after a while, it started to fail. On closer inspection, I could see that the cardboard starts to mould into the shape of the spring connector and hence loses it's clean contact. Using a piece of rigid plastic to prop the antenna contacts stops this happening. If you look carefully, the lower antenna on the back cover contains a piece of rigid plastic to keep the antenna from deforming.
The easiest way to tell if you've got "faulty" hardware is to firmly squeeze the top right of the phone together (about a cm down from the top) whilst having GPS test running. You should see a sudden increase in signal strength.
FYI, I've got the UK Vodaphone LG G2 = D802
Didn't notice any difference here.
did this today and FINALLY fixed the GPS. (didn't realize i had a GPS issue until recently since i rarely had use for it before). For anyone who is still trying to fix it...my tips are:
-use a guitar pick to pry the back open if you dont have a prying tool
-like in the video, get something like the cardboard off the back of those notepads you get free
-make sure the piece is large enough to go under each connector, the idea is to just give a better connection with the pins
this was the only fix for me. before i couldn't get a GPS lock at all. now i can get it in under 10s

Wifi signal problem,very weak

Hi experts and xperia users.
I went thru this forum and looked for the same subjected question but had no luck.
Pls advise me how to resolve my wifi problem. I stood very close to a hotel access point and my m4 only discover 2 bars of signal,compare to my xi***I it got full bars. Wifi analyzer said 30db but m4 only 50 something
I tried move to another space in my home and school, restaurant with various AP brands my m4 still got bad signal,even the M4 placed very close with AP.
Pls don't tell me to make static IP, or change AP configuration.
Pls help.
Maybe your m4 has problem scanning wifi.

@outofmemory13 finally i am able to open ur image. However it is not clear enaugh for me,sorry. So:
1. Is it located at top left of the back side?
2. You replaced the back cover and wifi signal work better?
Exactly.
on the back cover there's black sticker - this is NFC antena shared with Wi-Fi.
w/o antena the wifi works... just like IrDa in old phone So... That's why I'm think, that is problem with connection between cover and main PCB.
The antena maybe is damaged by default. Also I forget to mention that the antena maybe doesn't adhere into cover(check this by pressing this place* with little pressure - if signal is better - let me know)
*top left > 1cm down.
It does not work for me, even I take off the rear case (without case) no improvement, still weak.

Yeah, without the rear case it'll works like this.... even worse.
1. use a multimeter to check that two copper plates have around 0 resistance.
2. It can be weird, but try add some tinfoil(into the plates) to improve connection between cover and pcb. Carefully. And check again.
If doesn't work - it's a problem with Wi-Fi sensor. Unrepairable.
I've fixed 3 M4 with the same problem so far. Can't belive, that in this case all my instructions aren't working, maybe there's another issue, I guess... Anyway, check it and show the result.
#I don't like English... case, case... the same words and another meaning...
I have no luck on this and plan so sell the phone thank you all for the advices.

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 !
