Xperia Z3 :: Loss Of Network Signal During Night And Sudden Call Drops
Oct 4, 2015
I'm having a strange problem with my new Xperia Z3 Dual ever since I updated it to Lollipop. I’m using two SIM cards from two different operators. But every morning I notice that there is no signal available for SIM2. Signal comes back to normal on SIM2, if a call received or if I made an outgoing call from SIM1. Otherwise I have to switch on to Airplane Mode and switch it off every time to get the signal back. Because of this issue the battery drains so fast during night (due to loss of signal for 6-7hrs). And also I notice sudden call drops during conversations within 5-10 minutes after receiving or making a call.
I checked the same SIM using another phone to get verified whether this issue is related with the operator. But there I didn’t notice this strange behaviour. Hopefully this is something related with my Xperia Z3 Dual. I’m using WCDMA(Preferred)/GSM on SIM1 and GSM Only on SIM2.

I have recently purchased a Z3 Dual sim D6633 and around twice a day either when receiving or making a call the phone suddenly drops out during conversation and both network strength bars are showing no signal. a message briefly shows up saying no no network signal ( or something to that effect ) then dissappears. A few seconds later the signal comes back for both sims and all is ok again. Why this is happening but its becoming frustrating especially when I have to call clients back.

My Z5C plays a sound when it loses or acquires mobile network signal. This is very, very annoying in areas where network coverage is bad. How to turn it off? I remember it being easy pre-5.1.1, but now i can't find any way to do it.

My XPERIA Active (ST17I) lose connection to cell operator network, very often. For Your information, other brand phone with the same Sim card works proper with stable connection, in the same place and time. After investigation, turn GSM only and cell operator (Kyivstar UA) selected manually, my phone has little bit better network registration, but still lose network sometimes for no reason. Firmware updated to last version, but no changes for the above issue.

I have an exclamation mark (-!) on each call on my log list, I can't also check my balance I.e *144# isn't responding. What could be the cause of this? My device also looses network frequently...

I listen to the phone's FM radio a lot and and play some of my music, and that side of it is important for me. I have a few different earpieces/buds including a couple of SE's that have come with various phones, All was fine yesterday, but this morning I went to listen to some music and the sound was barealy audible - it was playing, but through the earpieces it was extremely feint. Plays fine through the speaker however. I tried six different earpieces, one that came with the phone so is known to be compatible, one that came with my second phone an X10 mini, and two that are generic but work fine with the Ray, and they all had barely-audible sound the same.
I tried the same earphiones with the X10 mini, and all work fine so the earphones are all functioning perfectly.I downloaded a free music player app to test a new installation/registry/files/whatever, but same results. So I suspected a software fault, and did a factory reset (yes, it is that important to me) but still with the same result.BUT that was when I noticed ... when recreating a couple of things again I brought up the FM radio to have it scan for stations as the reset left it empty. Although it recognised that the earpiece/aerial was connected ok there was no movement of the scanning progress-bar/window and then it closed down leaving the tuning-scale on screen but no stations ... I could manually swipe up and down the tuning scale no problem, however no stations were heard/found/registered.
I repeated the 'empty' radio on the X10 mini so I could test the earpiece/aerial function, and when then retuning-in it found all the stations in a heartbeat with both SE earpoeces - I didn't bother to repeat it any further with the others, no point.It is easy to suspect the earpieces until they play the music fine on the other phone and also scan/play FM radio channels... and it is also easy to suspect the phono/wire/connection until you realise that they are transmitting the played music just not at a listenable volume without straining... and also i is easy to think the aerial-function is faulty and it doesn't interface, until on another phone it grabs plenty of channels in its scan in just moments It hasn't been dropped or in water or anything, just worked yesterday evening then not this morning and it was only on my bedside table overnight.
I am still happily on Gingerbread, haven't bothered to go to ICS, not that fusssed about it TBH - so it hasn't been caused in an upgrade/incompatibility problem with ICS.I actually did upgrade to ICS hoping this might cure it, but it was exactly the same then too!So I flashed the phone back to GB (Flashtool+appropriate .ftf), but still it was exactly the same - very low sound and no station search/reset And that's where it has stopped at now.i am thinking I have missed something blindingly obvious, but now I am too close to figure that out anyway, plus also am undoubtedly in need of someone expert.

I'm having problems with my iphone 4s it keeps dropping calls and then loosing the network temporarily. I'm in the UAE, anyone else experienceing the same here or elsewhere? I have read it might be related to the ios 5.0.1 update, which I did last week, and then the problem started.

The latest FW upgrade seems to have provided the following irritating 'feature':
Whenever my Z4 loses or regains reception, it vibrates twice at me. This is very annoying and unnecessary, and how do I turn this 'feature' off?

Ok I switched this week form iPhone to Android purchasing a shiny new Z5.
Because signal where I am varies dramtically from 4G to 3G etc so just changing rooms in my house will get me this notification.
Driving to work will get me several notifcations so its extremely frustrating, especially when it cuts in to songs etc that I'm listening too as I use the phone while running, it's also my main source of music in the van.

I recently noticed a strange behaviour during standby on my Xperia neo (FW 4.0.2.A.0.42). Since I use a brand new SIM of German network carrier E-Plus my Neo seems to randomly lose network signal completely. This sometimes even happens without any change of location. However, this occurs only in standby. As soon as I turn on the screen the network signal will be re-established immediately (-> screenshot below). As I can receive calls and text messages during these 'no signal' periods I would assume a software bug. However, I didn't notice this behaviour with a SIM of Vodafone which I had in use a couple of weeks ago.

my x10i keeps dropping its wifi connection. it is in an "excellent" signal strength area. i can now see that is related to my poor mobile network coverage at home. when the mobile network signal drops, then the wifi turns off and the turns on again, scans and reconnects. when the mobile network connects again (after a minute or two) the wifi turns off, then on again, scans and reconnects. this cycling is happening every minute or two. which leads to lots of frustrating network errors. exact issue described below with Internet clip: [url]. things improve if i turn off 3g and set network to gsm only.

I want to sent it to warranty service. When I keep my phone in hand signal vary all the time and very often i can see that i have no access to my network, it happens also in big city. The other problem is electrostatic noise which was mentioned several times. I'm afraid service will do nothing so I wanted to ask what should I do to get my phone fixed (I read a lot of people had to sent their phone several times and wait 2 weeks every time until it was fine).

It doesn't happen all the time, but maybe once a week. I'll be using it and all of the sudden the battery will drop by 20% to 40% in a matter of seconds. See the attached screen shot for an example. This happened both before and after the Ice Cream Sandwich update. I haven't been able to link it to a particular app or service. I have done a hard reset on my phone and the problem persists. Also, with the example shown in my screen shot, I was doing a Google search using the chrome browser and the battery level dropped from 40% to 5% in a matter of seconds. And as you can see the battery level hasn't changed since, it has been at 5% for two hours or so without a change.

my calls started to cut off while i was talking.videos (in Internet), started crashing. only fix was to reload the page again, and then watch from the place wher the video crashed, but it could crash again. it happens randomly as well, no time limit, sometime i can see a 10min video with no worries, but then next video cuts down in every 2min.some other installed applications started crashing.ram reports tell me that the usage is around150-160mb, so 150mb is still free.there's also plenty of space in the phone and memory card.

I have a Motorola Electrify 1 from U.S. Cellular. I have had the phone for about 3 months and before that my husband used it for about 9 months. For about 5 days now I just randomly lose my 3g signal. I cant get phone calls, texts, or anyother notification on my phone. I have to turn the phone off and then back on so that I can make a call. Also, sometimes when placing a call my phone just turns itself off. What is going on? I reset the phone to factory settings and still am having problems.

I have a problem with my phone. I only get 2 or 3 bars in my house and at work at the most. When I plug my phone in to charge it everything is fine until about 90 percent charged. After that for all intents and purposes I lose signal completely. Sometimes it will just show no bars, most other times it will got into searching for CDMA and then no service. It does not change when the battery is fully charged either. The only thing that fixes it is unplugging the device. It doesn't matter what outlet its plugged into. Ive also tried it at work and home and I get the same results. It does not do it if its plugged into the computer charging on USB, but it does charge a lot slower.
Im on Verizon
Phone is Bold 9650
Os is .732
Only apps I run are weatherbug

Well yesterday i have dropped my Blackberry 9900 in the pool. I then directly used the rice method and left it all night. In the morning i have noticed two red strips one on the battery and the other one in the inner side of the phone where i place the battery. I have been told by a friend that this is the water damage sign. After i noticed the dark pink redish strips i decided to switch it on to verify that everything is working, and yes everything was working fine including the buttons. However the signal was on SOS only!! i thought that the SIM got damaged so i used it with another phone and it worked with connection signal full bars!! but when i put it back into my blackberry the SOS sign appear again!

almost since day one, i have not really had the pleasure of enjoying what 4g signal is really like. i'm in chicago, and when ever i'm either downloading music or streaming video (netflix, Internet) or downloading anything that requires data, the phone completely loses the 4g connection and takes at times up to 5 minutes for the signal to come back. if i keep the phone on 3g only it does not happen, but that defeats the whole purpose of having a 4g device. the "data saver" in settings is off.

Finally got my new iPhone 4.First thing I noticed was that the signal dropped to nothing when I held it in my hand at the bottom of the phone .the same way I have always held an iPhone.Made a phone call yesterday and the call dropped when I accidentally moved my hand to the bottom.Do the bumpers actually solve this problem or is that a myth?
