Signal Dropouts

hey!
I have a problem with my One Mini. I have constant signal dropouts. Phone calls stop after a second, also losing data-connection all the time and always seeing the message "Preparing SIM-card".
It feels like my phone having problems with some mobile-cells. Usually I have to try to call someone 3-4 times, and after 3-4 attempts I can talk normally without getting interrupted after 1-2sec - like my phone found the correct cell or something like this.
I tried
- my second (O2) sim-card
- put some tape on top of the sim-card (solved this problem for people with different phones)
- put some signal-tweaks in my build.prop
- changed network mode (WCDMA/GSM/LTE...)
but nothing helped.
I am on O2-Germany for many years and never had those problems, my One S was working fine (before it got bricked )
Had the same problem last month in France...
anyone else having this problem? could this be kernel-related? I'm using JMZ`s kernel. But I guess this is more a radio-problem, or?

I haven't had this issues, in fact, I went camping last weekend and most of the time I was able to get 1 bar when everyone else didn't have service at all. I'm using the AT&T variant on AT&T with the WWE DeOdexed Stock ROM and Jmz's Kernel 09-04-13. I attached a picture of my kernel, baseband, build, ect. I'd suggest making a backup and restoring your phone to stock to see if it's a software issue.

Cannot make or receive calls(Emergency calls only)

Hi,
From past three days, signal is not showing up on the phone. And it only shows a red triangle with a white plus sign on it.(Emergency Calls Only)
I didnt do any changes to the phone, it just randomly started three days ago.
I am on Indian version of unlocked Motorola atrix 2 MB865.
I am on jellybean 4.1.2 for past many months. So I dont suspect the ROM.
I have tried using some other sims also.(It is NOT the problem of the Sim)
I usually get full signal at my place.
I have searched internet thoroughly and read almost all the threads related to this topic, but it didnt help me much.
Things I have tried till now.-->
- Swapped sims with many other phones.
- Installed the "Network" app and many other similar apps which was suggested in some other threads.
- Switched Flight mode on and off.
- Factory reset the phone.
- Kept it off for hours and then checked again.
- Prayed that it will get fixed soon
Q) Did you try turning it off and on again?
Ans) Yes..yes.. Many many times. Sometimes, after reboot it shows signal for 2-5 minutes, but I CANT make/receive any calls/sms(The call just drops two seconds after dialling)
PS:- I think that when I received the last call, I was listening music on my headset and I had received the call with the headset.
Thank You very much.

Baseband version is showing as 2012-0712 09:44 Off Blf LUD_EDISON_R1E_PATCH_36_120712_0920 ch1090280_M570_PC_CARD_RAINB

I have now found that it is due to very very poor reception.... For some reason, this phone's signal reception has drastically reduced.
I can get signal only if I go out, still the signal strength is shown at maximum -75dB and frequently dropping to -100dB. I was able to make one call and it dropped as soon as i entered inside the house.
(The same sim on other phones have full range even inside house)
What is the suggested solution?
Thanks

Seems to be a hardware issue then. Is your phone within warranty, by chance?

Nop it is not in warranty.

If you can't afford to help, then what's the point of this post?
Increasing post count I guess.

Might be a loose connection after a drop ?
Your best bet would be to dissamble the phone and assemble again. In the meantime check the connectors and others if they're in their place. There're good disassembly videos for atrix 2 in youtube.

K s h i t i j s, who is your network provider? EDIT: Just saw that you're on MTNL.
I have been having a similar problem for a similar length of time with my Atrix 2 and I'm on stock ICS. I got my sim replaced by Vodafone but the problem persisted so I asked the guy who originally sold it to me to get it checked out (warranty is long gone).
He mentioned that another customer of his with the same phone also developed the same problem around November or December 2013. Both that guy and I are on Vodafone, Mumbai.
In testing, his phone worked perfectly with an Airtel sim and mine worked perfectly with a borrowed IDEA sim. Both our sims work perfectly in other phones. Both were then sent to the official service centre but they essentially threw their hands up.
The coincidental timing of the problem for two (maybe three) phones of the same model leads one to think there must something with the network broadcasting? Could someone with better knowledge of the subject (mine is approximately nil) comment?

[Q] Tmobile samsung vibrant dropping signal/bars falling/disconnects from network.

I stay in africa(uganda) I sold my nokia n900 to buy a used unlocked tmobile samsung S 4G vibrant which has become my worst nightmare...the phone drops network signal and sometimes when I pull it outta my pocket it will show (searching) but will connect after 30minutes else i have to reconnect it my self in network setup..all that was not a problem to me because I work in the capital were network is always up in 5bars both 3G&2G but loses it quickly in some building..
Problem:
When I leave the capital just 15 minutes away it starts to drop signal from 5-0 but will regain in some places...it does this in areas that other people on the same network as me won't get a problem so do my previous 3G phones including the previous n900 I owned.
Things get bad when I reach home in that I barely get a bar in 3G and only 5-4-3bars in 2G it keeps on playing and in that process it will go to (searching) until I reconnect manually which forced me to look for a solution on the internet.
Solution I got:
Connect magnet wire in the back external antenna input at the back of the phone, guess you all have seen that hole, in the video the guy got 3bars from 0-1 bar which convieced me that my network problem is now solved.
Starting the trick:
I cut my tv antenna wire in two pieces, removed three thin silver wires and tested one by one.
The first two failed but the third one brought the network down from 0bars of 3G upto 3bars 3G.
Going on with the test now very happy I try a more fitting object I inserted the niddle which I used to remove the rubber cover which covered the external antenna input.
My nightmare begins:
Immediately after I removed the niddle, the signal bars all went off to X but mine shows a circle and a line touching both sides.
When I reinserted the niddle I got the signal back but this time only 2bars for 2G which was 4-5 bars before and 0bars for 3G which could dare 1bar.
finally:
Now I just removed the niddle, network went off again now my phone was relying on the niddle maybe the internal antenna was now disabled or ruined by me.
I hard reseted the phone, cleared cache but all didn't work..i put back the niddle in the hole It all came back.
Yesterday I took it to a local repair shop and today when I picked it I had -79dbm 2G and -53dbm 3G but when I left the shop 15 minutes away I got an X then 5-2-3 bars of both 3G and 2G..thaugh i got the network back without niddle support. The network is badder than how it was when I first bought the phone.
What the repair guy did:
He rolled a copper wire around the external antenna input and soldered it to an object just near th ext antenna input.
Finally:
What could have been the problem in the first place?
How can I solve the problem?
Phone: tmobile samsung galaxy s t959v vibrant.
State: unlocked and being used on airtel uganda.
Android Version:2.2.1
my last say: I have tested 3 different 3G phones with my simcard and all have performed well in my house with full bars and I don't remember having network issues with my previous 3G nokia phones, my brother who has a galaxy pocket doesn't face network problems either..i have tried all network operators with no success but still the same problem and now come for your help because after the niddle night, alk has become was! I like the phone soo,much cause its my first android but am afraid I can't have it like this, friends call me and it has already disconnected from the network even when the bars are still there in full swing..........

3G cell reception issue and fix

I just want to write this post maybe it will help anyone that has or will have the same problem. I looked all over the internet and could not find a fix, so here is my fix. Hope it works.
I work over seas on oil rig sites (remote locations) so I talk to my wife and family back home via different VOIP apps so its important to get a 3G signal, usually I lock WCDMA only network and get at least 1 bar which is sufficient. All of a sudden I started experiencing very weak 3G signal on my phone, weirdly this was at the same location where it had full bars in the past. This only applies for 3G, I could get 2G signal no problem.
In other areas that I know had good 3G signals and towers were close, it would work alright outdoors but once I get behind a door or a window 3G disappears even if I have it locked. I put in my sim card in my old Galaxy Nexus and it had 3G indoors with no problems at the same place and right next to the N5. So I started testing with both phones right next to each other when I lock 3G with the same SIM the Galaxy nexus would get 3 bars while the Nexus 5 would get the empty triangle (emergency calls only).
I couldn't get out of my mind that I dropped my Nexus 5 a hard drop, but I have a rubber case that took all the shock and the phone didn't get a scratch on it. This was before the 3G signal starts getting funny. Couldn't help but feel that I broke it somehow though. I felt like this might have got something loose inside. What didn't make sense to me is that if the antenna didn't work it wouldn't get 3G at all, indoors and outdoors.
So Step 1, I assumed it was a software issue. I went through a painful hard reset. To my surprise it still had the same issue afterwards.
Then out of desperation I saw this dude's video on how he couldn't lock GPS until he opened the back of the phone and found that the GPS antenna was not connecting straight.
youtube com/watch?v=K1-uCIb-t8I[/url]
So I started searching for where the 3G or 2G antennas are on the N5, but couldnt find anything that points that out. The phone was worthless to me like that so... I took a deep breath and decided to open the phone. Keep in mind, i'm an oilfield engineer and I still had a feeling i might [email protected]#k the phone up, specially that I did not have any tools with me.
So I watched this video on how to open up the back cover:
youtube com/watch?v=mkbmtu-1KSQ[/url]
and went through this guide on what's inside the N5:
theregister co uk/2013/11/05/nexus_5_teardown_shows_a_light_touch_thats_easy_to_fix/[/url]
Then I opened it, couldn't find anything to do, except maybe clean the minor dust off and blow on the ICs a bit. There is alot of pins that connect to antennas located on the back cover itself, so I closed it up, made sure its closed tight and all the pins touching, put in my SIM, and GOD DAMN!! IT WORKS AGAIN... I was getting full bars 3G!!!
So what I figured is that when I dropped it, one of those pins moved a little bit away and broke the connection between the antenna and the IC. Works great for the last 5 hours, solid connection.
Hope I would help anyone with this

Thats nice , but lots of ppls have the signal issues with nexus 5 , and it isn't antena disconect for 90 % if us. I have separated the phone many times. , done about 5 hard resets's tried diffrent verions of radio's diffrent ROM's etc... nothing work's. Frineds have nexus 5 2 of them , and they can get 3g and 4g when they want, and i can only get Edge which is 2g. which is unusable..... I noticed that i have 3g only when i am in other towns, but not mine home town.... I tried diffrent sim cards, and diffrent netowrks, nothing seams to get the 3g at home, plus the gsm sucks, it interupts the calls.. So i must be the frequencies of the working 3g network in mine home town ? Then how i don't get 4g ? Why other ppl with the same phone, and same network have 3g when put next to mine ? NO one knows...

Same Issue
i am having the same issue, just having "E" Edge and cannot connect to 3G/4G, done everything to resolve the issue, took apart the antenna part of my phone but all the connectors and wires are intact, did hard reset several times, tried different ROMS including stock ROMS, tried the *#*#4636#*#* selected all the Radios but no luck, used 2 different sim cards but no use, same damn "E" in the status bar, APNs are all in place, nothing is wrong with the settings so far, dont know wots da problem with this set.
Please help us.

No signal

Good day, today I dropped my phone don't know if it lost signal after this didn't notice until I tried to make a phone call but now there no signal, can't make or receive calls, I notice that at the bottom of the screen it shows my service provider name and next to it says no service so don't know it its hardware related or sim, do you think that if I reset the phone it might work again? Thanks. Right now can't test because I'm at work, but in general information on service it says disconnected
Sent from my Nexus 5 using xda premium

Flash stock with fastboot, if it's the same, it's hardware I'm afraid.

Thanks a lot did already, tried everything seems hardware related, noticed that it also lost nfc connection wondering rich part should I replace to fix it, if only has to do with antenna or the whole mainboard

The NFC radio and antenna are connected to the back cover. Try popping your back cover off and on again.

Thanks already did and nothing, could it be related to some other piece?

go to your dialer app and type in #*06*# and see if a number pops up (your imei number) (dont post the number here)

Did too, also the *#*#4636#*#* and checked if signal was turned on, tried sim in other phones works without problems, I noticed that nfc is not working too, guess it has to do with a piece of hardware as far as I know both antennas are in the back of the phone. Took it to service and they told me it has no problem physically, this is driving me crazy

Also checked that it has no reports of being stolen, imei seems correct and legit checked it also on a site to see if it's valid and its working, it starts with a 32.

My phone wouldn't connect to any network after being in airplane mode on vacation for a week, acted like no signal - empty triangle instead of bars. I called my cell provider (T-Mobile) and after a new SIM and a factory reset they did something on their end because my phone was trying to connect to a tower that didn't exist. I'm a little fuzzy on what they actually did, but it worked. I actually had to do it twice over a couple weeks before it stopped giving me trouble.

thanks friend will have to go and check with them , dont know if its the same because my phone has no cell provider it accepts any sim you insert to it

Hello
Hello guys, I am on the same boat as Valholy described.
My phone fell on the ground from my hands. When I took the phone from the ground... it was still working(it wasn't shutdown nor restart), I only noticed that there was no more signal. Tried to restart/shutdown, factory reset, different sim card but no luck at all... As Valholy described it shows provider's name on the bottom of the screen, but there is no signal yet.. It seems like hardware issue. Any recommendation to fix this issue?
Did you fix your phone yet, Valholy?
Thank you

bump...
any help please.
thank you
