Phone loses reception, restart to get it back?

Love love love my Desire. Few little problems here and there (Music Genre, Battery life etc) but the one main thing that is really bugging me is, that if I lose reception (I live in a area with lots of valleys), it will never regain reception even if I enter a town centre or City. I always have to either switch Airplane mode on then off. Or more often than not, turn the phone off completely and switch it back on, where it then finds reception straight away.
Anyone else getting this?
I'm on Vodafone and using the latest Generic Rom

I'm not sure if this is the same problem, sometimes i
have no data connection (i guess 3x since i have the phone).
I see some bars but no Edge or H (3g) sign and obviously i have not data connection ... dunno if the phone part work, will try next time.
anyway, i could get the data connection back by switching from 3g to GPRS mode and later back. You can see in the bar that for a very short time all GSM connection is gone ... i guess it's similar to switching to airplane mode ...
Maybe it's worth a try for you, maybe it's totally useless
btw: i'm living in a city, the nearest celltower is just a few meters away.

I have similar issues but I had the same issues with my ADP, not just the Desire.
Inside my University buildings I lose reception very often and the GSM connection always reestablishes itself but not the Data connection. When I reboot my phone the same thing happens. There is a good chance that the Data connection wont initialize and I have to switch to Airplane mode and back to get the Data connection. Really frustrating sometimes :/
Another very, very annoying problem I have is that sometimes it shows a data connection but it can't be used. It shows E/3G/H but whenever I start an app which uses data, it always times out.
Another problem, which is probably not fixable, is that my Phone likes to jump between E/3G/H quite a lot and every time it does do so, it seems like the app using the data connection has to reestablish the connection. This led to quite some timeouts when it was constantly jumping around.

I get poor 3G reception on my desire ( orange UK ) , have to go outside in the rain to get a better reception

vodafone have been getting worse and worse of late, I travel from surrey to london (central) every morning and was getting the same thing. I was even getting this all the time with a blackberry 9700, It is not the phone as I tried tmobile sim card in the same areas and didn't have the problem. Only 8 months to go of my contract which I will not be renewing.

I have an issue where if I use wifI at home for an evening, when I switch wifi off, the 3g data connection does not re connect. If I re boot, it connects immediately.

Assuming Vodafone uses Sim cards. I just had the same issue, here in the states with AT&T. I thought my Tilt was at fault so I borrowed a little Samsung flip phone and put my Sim in it but it did the same thing.
I had AT&T replace my Sim card and so far, 48+ hours, it hasn't happened again on my Tilt.
Might be worth a try.

Thanks, might try changing the Radio version and see if that helps first, if not will give Vodafone a call.

I have this same problem at home (in South London) with my desire and had it with my G1 too (both on T-Mobile). I'm pretty sure it's a network issue rather than android or the phone. I constantly have 3 bars of H signal and during the daytime it's blazing fast but after around 5pm and all day at the weekends it becomes basically unusable with network timeouts more often than usable connections. I work 40 miles away down south and I get a consistently fast data connection down there with none of the time out problems.
I also tried using a t-mobile sim in a 3g dongle and had the same issues, it was great during the day and incredibly slow with loads of timeouts in the eve. It reminds me of when unmetered ISPs first came out and couldn't cope with the amount of bandwidth being used, I'm pretty sure this is a similar capacity problem in some areas.
I've been in touch with t-mobile and they are escalating it to 3rd line support so will wait and see what happens. As it's at home I can use wifi and it's not the end of the world but it some respects I wish I hadn't upgraded and switched networks instead, my gf's on O2 with the phone that is not to be named and doesn't have this problem at all.

In response to your most recent query on a different thread you had posted (now closed):
Will changing the radio help me?
Currently got this issue happening daily
http://forum.xda-developers.com/showthread.php?t=676866
If I lose reception at any point, I have to either turn Airplane Mode on and off or restart the phone to get ANY sort of reception.
Currently on 1.15.405.4 Generic Rom with Baseband version 32.30.00.28U_4.05.00.11

Yes, by updating the Radio version this can improve things like battery life, network reception, Wi-Fi, and GPS signal strength, but this also depends on your region - it will either work better for you or could be worse. It may be worthwhile changing to Radio 4.06.00.02 for a few days and try to establish whether or not it improves your situation. If it doesn't, then just revert back to the stock Radio version.

I had a very similar problem on my Touch Diamond 2. It turned out to be a faulty aerial and had to go back to HTC for repair. Worked ok for a while after that, then it started again. An update to their latest ROM then solved it. So a hardware issue and a seperate software issue both produced the same fault for me.

s4 mini duos network problems

Hello,
I appeal to all the users that have samsung galaxy s4 mini duos (i9192) to give me a honest opinion on their experience usage about this issue
I want to buy the phone because i have 2 sims, work and home and need both always on but i've been read that this phone has major problems with network signal such as:
"Poor network performance. I'm forced to restart 4 to 5 times per day to regain the network access. I checked from my service providers, no issues on their part. Dual Sim a failure. Apart from network issues, the design, ram performance are average. I'll recommend not to buy this instrument unless the dual-sim network problem is rectified."
Like this, there are many more in samsung phone forum.
Anyone can give me their opinion?

False. I'm using it without problems with two sims work/private. Signal strength may be lower, but it's not so bad. Device is very fast, in antutu it has more points than 4 core htc one x+ or galaxy s3.
Software is bit buggy, but nothing serious.

Thanks for the quick answer.
Yes, i have read many reviews and all shows very good results. But if you go to http://reviews.in.samsung.com/7463-en_in/GT-I9192ZWAINU/samsung-galaxy-s4-mini-reviews/reviews.htm you will see the very bad opinions.
Seems that the phone in bad coverage areas lost signal and don't regain signal unless you restart the phone or the network. Have you already been in bad coverage areas?

It will regain signal. For example yesterday - I was in underground parking lot and signal was very poor to none, but somehow I've got the incoming call when moving to other spot.
Maybe it's firmware related. I've updated manually to amh2 version through odin. Mine new csc is ser - Russia

Anyone else that has not experienced this problems?

I would like to know this also, I'm considering buying it solely because of the "Dual Sim" but I keep reading lots of people complaining about the signal issues.

I dont have any problems with my I9192 been in my hands for 2 months by now the network problem you describe it's very rare just couple of times since I've been using it but I've turn on and off airplane mode
for me it's a really good phone

Same problem
I also have the duos version. Once the signal is lost/falls in the dead spot region, it doesn't come back a automatically. Fed up with this.. after buying such a high end phone, restarting all the time to get network! What is the use of fast processor and all stuff if we can't make a phone call with it? And after reading the comments on the below page, it is clear that this is a known issue of the model:
gsmarena.com/samsung_i9190_galaxy_s4_mini-reviews-5375.php
Any solution for this? The handset has turned out to be useless.

I have not had a problem like this with mine, it works perfect. I live in a bad signal area and if I go down stairs in my house the phone will lose the signal , when I go back up stairs the phone always regains the signal with no problems.
I can't fault this phone, it's ten times better than my last one, HTC Desire V

Thanks,
Only the fact that you mentioned you have to do airplane mode 2 times is just severe enough, because in a phone with this price range that's a problem that should NEVER occur, and you can be the lucky guy that just has good coverage signal all of the time.
I came to the conclusion that it happens with much moore models than the ones that not happen.
I'm going to order the phone even with this feedback hoping that i have a flash of luck and my phone doesn't have the problems, because i've been waiting months for a dual sim phone with top performance and this seems to be the ideal phone to me.
I will post my experience here, if anything goes wrong i will try to sell it.

I don't know how a brand like Samsung brings to the market a phone in this price range with these problems. And worst, dont't give a solution to them. Did you try to contact Samsung or use the warranty with them?

Same Issue with Samsung GT-I9192
Hi All,
I am facing the same issue with my Samsung GT-I9192, which I purchased on 1st Sep.
I am using 2 simcards, one being Vodafone and the other Idea, India region.
Surprisingly the issue is only with Vodafone, where the signal after dropping (very frequently) does not refresh.
In case of Idea simcard, the signal refresh is working fine.
I am not able to understand if the problem is with the service provider, sim card, hardware or the software.
I used my vodafone simcard with Galaxy Core (another dual sim phones), and they seem to work fine,
which gets me all the more confused.
The only difference that I notice is in the Mobile Network Type.
Its EDGE:2 for Vodafone and UMTS:3 for Idea, wonder if this has got anything to do with the network issues.
I did the default available 2 firmware upgrades since purchase, they seem to have worsened the problems.
Let me know if you are facing the same issue, with the same service provider.
Need to keep a close watch on the solution, as it seems to be affecting more people than expected, surprisingly couldn't find any issues a month back during the time of purchase....
Regards,
Varun

In my case, it's Vodafone also, but is in Western Europe.
My concern is that i have exactily the same problem in my present phone (Sony Tipo Dual) and it's the main reason (along side the big improve of speed and etc) for buying this phone. At the present, people call to me and they say that phone answers occupied (no network signal) and i look to the phone and it shows top signal strenght. I'm beginning to think that dual sim phones with android have some limitations (maybe antenna limitations).

In my case S4 mini network refresh is not working for secondary sim (aircel India) and working fine for primary sim Tata docomo. I buyed this mobile as it has 1.5 gb RAM with dual sim instead of Nexus 4.

thats true it should never occur, i think its implementation problem, android its not mean to be for dual sim phones the solution for dual sim on android its a samsung workarround, it should not be buggy but has some problems it does not make the phone unusable for me, I don't get coverage all the time, I travel from city to city and get poor coverage all the way so i think its not a big issue since it happen just a few times.

Hi Sriram,
My problem is very similar, Vodafone on either sim slots gives network problems, and Idea on either sim slots works fine. That makes me think that the problem must be hardware / software related to Network type. Its EDGE2 for vodafone and GPRS1 for Idea. What is the network type of your sim cards?

Phone defect.. Not related to Sim card

I use idea in the first slot and BSNL in the second slot. The trouble occurs with BOTH SIM. Earlier I used idea -Vodafone pair, the problem was still there. I live in am area where all operators have weak/varying coverage. Airtel and aircel have already been reported as showing same problem. All the users are affected with this issue, so it is clear that this has nothing to do with the operator, it is a fault of the phone either hardware or software. I think you have idea Sim working fine only means idea network is better in your area and may not need frequent network cell changeover. (?) And another fact we can see from the reports is, that, almost ALL THE COMPLAINTS have been reported from INDIA where the model released is the duos.

S4 Mini Network issues.
I too have a S4 Mini for less than a month and I am also facing network issues. One thing to notice is that the sim with internet doesn't have issues. Irrespective of which slot it is in. Currently I have Vodafone IN on Sim 1 and Airtel on 2 (with 3G). Airtel works fine and Voda has issues.
I did speak to Samsung care, they were very nice, however the problem wasn't solved, I have been adviced to go to Samsung service center and get the S/w reimaged.
I still haven't done that, however what I did was to reset the phone and while I was browsing on the play store I got a software called "Where is my Signal" by Grey Boy. For some reason I feel it is working fine now. I have not had any issue from last evening, baring one time when I was on a long conf call for around 150 mins today. else it has been working fine and receiving calls on both sims too.
I had used this software to refresh the network once, it has helped me, not sure if this is going to sustain but for now it is good.
If some one else also has this software installed and is finding this to solve the issues kindly post the same on the forum and may be helpful.
Will repost tomorrow again with the status.
BTW I agree to many opinions in this thread that Samsung should have done some testing or atleast after many of these issues coming up needed to provide a patch upgrade.

I had tried three apps of that kind: where is my signal, network booster(marcstealth), and network refresher lite. None of them could overcome the strange problem of this phone though at first they seemed to be working. Another question is, how do we know when to refresh network? If we know the signal is lost, we can restart or do something like that. Then there is one more issue: sometimes it shows good/full signal strength, but when try to make a call, will realize that it was false! I made to run the network booster app run when signal is low, using tasker app -but we are not supposed to live such a life using this celebrated costly handset.
But one thing in your post is of much importance. DID THAT RESET WORK? You haven't said much about that.

The reason for reset was to ensure that none of the softwares I had installed were causing the issue. The reset didn't change much compared to the way it was earlier.
Some observations of when the problem actually happens (again this is my observation and doesn't need to be the same in your case)
> When I am on a long incoming call on the sim which has Internet.
> Noticed that short calls don't impact the network.
> If there is a call drop imm after you receive a call.
I am planning to get the phone firmware re-imaged from the service center however I will need atleast 10 more days to do it as I am currently in a different city and I am not carrying the invoice copy.
BTW Rajesh, did u get any response from the CEOs office?

random loss of signal

I have a 128gb pixel XL with Verizon, which I purchased through verizon as well. Randomly at times just as I'm going to place a call it will start ringing and then disconnect and it will show loss of signal. This has also happened while I was on a call. I'm on the latest firmware as well. Has any body else ran into this issue?

I ran into this last night. I'm a sprint customer with pixel xl ordered from Google. I am on V software. It could just be the fact it's only connected to one 4g band which has low strength in the area we were at during the drop times. Mine hasn't done it since last night might have been in a dead zone

Yes, this has happened many, many times to me. I have a replacement coming that hopefully will take care of it.

For me its switching from band 13 to band 4.

I don't have this issue at all on TMO but in my area (Chicago) TMO is exclusively band 4. So this would lend some support to the possibility that this is happening when switching bands as I don't ever switch bands and don't have the issue (3 different Pixel devices that I've used since launch and none have exhibited this behavior).

I never had this issue on my Pixel XL, but then when I switched to the Pixel it would drop every single call I made and take 2-3 minutes to get a signal again. This was using the Verizon SIM card it came with. I then got a different SIM card and while it hasn't dropped a call since, I still notice that randomly throughout the day it loses signal where I have never lost signal before. I then wait 2-3 minutes and all of a sudden, it's back to strong LTE signal.
I'm on the fence about RMA'ing it. Anyone have any thoughts on whether or not this is a software or hardware issue? I don't want to be stuck with this problem.
-Collin-

Any resolution to this yet? I've tried swapping the sim to no avail. Running custom kernel and pure Nexus.

I'm on Project FI and sometimes the phone would switch to T-Mob for no apparent reason, which has extremely bad signal. While USC has over 100 times better signal, the phone for no apparent reason would switch to crap. That usually results in no calls being made at all. One trusty remedy is type in a dialer code to switch to next provider.

I also have the 128GB XL (quite black) from VZW. I had absolutely no issues with it until about 2 weeks ago. That's when I started experiencing this same issue. The signal bar goes clear and i lose service for a few moments. In watching the SIM status, I can see where the status will go from "In service" to "Radio off" to "Out of service" back to "In service." I also took screenshots of it doing this. The weird thing for me is that it only happens when I'm at work (I usually have full bars for reception). VZW seems quite baffled at this issue. They have replaced my phone twice. This 3rd phone is doing the exact same thing the other 2 were. I did a chat session with Google Support, and the 1st level tech I chatted with seemed unaware of the issue. My wife has the same phone (silver), and she hasn't experienced this issue yet at all. We were thinking about bringing her phone to my office to see if hers will display the same symptoms mine does here. Nobody else in my area has any reception issues. It's not a huge inconvenience while I'm at work since I have a desk phone. However, it is rather annoying when I cannot send a text or make/receive a call because my cellular radio is resetting itself constantly.
I couldn't post my screenshots since I have < 10 posts...

N920I - Weak 4G. Can no longer make or recieve calls. Possibly a local 3G tower was turned off.

My Galaxy Note 5 SM-N920I purchased December of 2015 can no longer make or receieve calls. My provider is TracFone via the Bring Your Own Phone program. I use their SIM card and it has worked all this time. Until recently the phones features have stopped working. I think they have been disabling the 3G in my area, as everyone is converting to 4G now.
Note 5 is supposed to support 4G but it's definitely been having issues. Text and internet still works. however texts are sometimes delayed on occasion, not always, usually it's fine. Data speed just now was tested at 10 mbps down, 3 mbps up. Signal bars are consistently low, regardless of physical location; inside, outside, other side of town, SIM status shows signal always between -108dBm and -118dBm. This is likely why I cannot make or receive calls, but the question is, why is this happening?
Like I said, I suspect they are shutting down 3G in this area, so the best theory I've been able to come up with is this: perhaps 4G has always sucked on this phone but I never noticed because it would fall back to the good 3G connection. Now that 3G is gone in this area, all I have to use is 4G which is a shoddy connection.
Further research has found in the early days of this phone there were numerous reports of weak/no signal. See these threads:

One theory was that the 4G antenna they used in the Note 5 / S6 was of poor design. Causing weak signal.
Things I have tried and did not work:
-Contacted TracFone. They confirmed the device is supported and provisioned correctly. They recommended a new SIM card.
-Replaced the SIM card with a brand new one
-Factory reset the device. It's running the stock Android 7.0 Nougat which was the last up to date version available.
-Tinkered with various service menus including *#2263# and *#0011#. Messing about with the LTE band settings didn't change the signal strength ever. Regardless of the LTE band, it stays in that -108 to -118 range, too weak for calling.
What can be done to fix this? Possible ideas:
-Internal antenna replacement, but this seems either expensive to have someone do, or extremely difficult to do oneself. Would it even make a difference? Has anyone tried this?
-Software. Could the issue have been introduced during one of the software updates? Planned obsolescence perhaps? Could we revert to an earlier firmware to potentially resolve this? has anyone tried this?
-Firmware. Could we upgrade the firmware to a later, unsupported version safely? Perhaps the issue was fixd in later Android versions but has not been adressed in older devices that are no longer updated.
I'm the kind of person who likes to use my things until they absolutely die. This Note 5 has been perfectly fine until recently. There is nothing wrong with it. It's still modern, fast, and has a great camera. I would HATE to have to replace a phone for such a stupid reason. Not only is money tight, but it's such a waste when this thing is still perfect apart from this weak 4G signal.
Has anyone else had this issue? Have you resolved it? Any help appreciated. Thank you.

Try a network reset.
Clear sim toolkit data.
Clear system cache.
The access point profile may need updating or maybe the sim?

Question Pixel 6 Pro network keeps dropping randomly

Hi,
I never had any issue with the Pixel 6 Pro so far unlike other users but it all started few months ago when I noticed that the network kept dropping randomly, sometimes I used to get "no service" in an area where I used to get 4G at full speed. I did wait for the July update to solve the issue but it never did. Right now I am on the August update that has been released recently but I see no difference. I cannot do a smooth phone call on my data as the network keeps dropping continually. Sometimes I am on 4G, the second later I am on H. I did think that maybe it was the network I was on, Vodafone at that time, so I switched to EE, here in the UK it is considered to be the best one. Still I am facing the same issue, then I can assume it is the phone. I have tried to follow every guide I have found on the web, but nothing seems to work for me. It is annoying that when you need to get something on the phone I need to wait for the phone to go randomly back on 4G hoping that I will stay on it until I get what I need. I have attached the video that I have recorded where I am in the town centre, where I can easily get 5G but the phone keeps dropping the network.
I use ESIM as well, and I have the same issue with it.
Has anyone had the same issue? How can I solve it? Has anyone tried Android 13 Beta? Does it solve some bugs that we have right now on Android 12?
I am really annoyed because of this issue I am facing right now, I love this phone but I am seriously thinking to sell it due to this bug.
Your browser is not able to display this video.

Of all the stuff people complain about, this is the only problem I have. The signal on this phone is an absolute disgrace. I lose signal where I used to get it on my Droid X back in the day. Not sure how they screwed it up that bad, but they did LOL

Turn off the 4G on the second SIM card. I had the same issue.

In denmark, mine also randomly get the no service and no sim, but it is the imr registration ther fails and i beeing kicked off the celluar network. that is thanks to googles phone are not sold in your country, so you got the finger by google...
I will work with jailbreak and so on, but many apps will stop working,.
For now my pixel 6 pro, are living a sad life in its box, replaced by a oneplus 10 pro, without any of theese issues..
it is a bit sad, the pixel 6 pro is at god phone, but google giving pepole the finger, if you buy the phone somwhere google are not selling it, i dont get it.. it is basic stuff expecting to work, the culluar no mattewr where you buy it.

I have a P6Pro, also on EE in the UK.
I had spotty network performance in the early days, but after jumping to the 13 beta it's worked flawlessly.
Unsure if this is because of A13 or due to EE "doing work in my area" as they're often prone to doing.
I'd speak to EE first, then perhaps speak to Google via the support button in settings - they offered to swap my handset out for me (I didn't swap it out in the end).

When I was on Vodafone I had the same text from them, still after their ' solved ' the network issues, nothing really changed for me. My friend who is on EE in the area as me does not face any problem. I hope that A13 solves the issue. It is not normal that a 800£ phone struggles with the network this much

4G on the second sim is always off. I will try to test it turning the sim off and will let you know, thanks.

Yeah I have the same issue as you are reporting, three drops in city on the train on the way to work. Just get the exclamation mark, does not seem to self recover, I go into the SIM and disable it, then enable it again, and it instantly jumps to full 5G signal. I do note that it is more reliable for me when I turn off 5G completely, and just use 4G, then it drops back to 3G but doesn't completely stop.
I think majority of connectivity on this device is crap. WIFI is hit and miss. Bluetooth is atrocious, super slow to connect to some older devices, was fine when the phone first came out with early firmware. Pairing devices is hit and miss and also new pairing.

I do agree with you for the connectivity, it feels like they have picked random parts for the phone just to launch it as soon as they could. The money they spent on advertisement could have been spent better on the hardware.
Do you use dual sim? As I have read, the phone struggles more with two sims

I have only had one SIM acitvated at a time at this stage, was having issues with trying to activate my Samsung smart watch activating 4G, so switched to physical sim, for easier troubleshooting with other mobile devices, maybe physical SIM is worse in this device

Yup had this. Ask for a replacement. Never happen again since the phone was replaced.

Update: the signal improve drastically on the main sim by keeping 2G or 3G on the eSIM but that generates a new problem, the eSIM drops the network on normal phone calls, it is not stable at all, if I call a number it rings after 10-15 seconds. I do not receive calls sometimes. It is just a mess.

Had the same problem, calls droppping or not being able to answer calls.
I had KPN as a physical sim and Simyo as a eSim.
I did resolve the issue, I understand this is not an actual "fix", but thought i'd mention it.
I changed providers from Simyo to Simpel, now I have Simpel as physical and KPN as eSim.
Since then no more problems also the option to turn on wifi calling showed up, so I think the p6p just wasn't playing nice with that specific provider.

I get random total drops of data and voice connection. If I hit Airplane mode on and off, it reconnects. Maybe the phone doesn't switch well between towers? I am on Google Fi.
Between the glitches and the lack of timely updates, and the abysmal battery life, I think this will be my last Pixel phone.
It barely lasts a full day with relatively light use, but if I use Maps and listen to Youtube (screen off) ad take photos in a new town, it dies within 6 hours or less. It has a great camera, but it's not useful for travel, because it dies so quickly.

I am having the same problem with my Google pixel 6 pro and it's been happening since I think the OS 11 certainly 12 and now 13. And I have AT&T service. But I can switch from my home Wi-Fi go outside of my car sit in my car for a while then all of a sudden the little! Comes up near the date of bars on my phone and use it after driving about 10 minutes or so it automatically will reconnect to the cell tower and get data. Sometimes I get well most of the time voicemails that people leave for me I don't get a notification until I reboot my phone. I actually put my phone in my right ear I can hear it loud and clear I switch it over to my left ear and it drops down by about 50% less volume I actually went and had a ear test done and they told me my hearing was perfect in both ears so I don't know what the hell it is with this phone but now I'd spent all this money going to the ear doctor thinking I was going deaf in one ear. Never had this kind of problems with my Note 4

I find in caernarfon I get good phone signal if i go to Bangor Tesco or sports direct in Bangor I get the exclamation point mark in phone signal and can't use it but signal has always been rubbish there I'm on ee
