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?

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.

calls are disconnected after few minutes

hi all,
stock 551ML no root, the calls running on SIM1 (4G) gets disconnected after 5/10 minutes. i suddenly see the radio bars disappearing, i can't hear anymore the called party, and then the call drops. Tried with 2 different carriers on SIM1. The phone is always enabled with 2 SIM's, but on the second one (whatever the carrier is) there's no such problem. I think this phone has large issues when dealing with 2G/3G/4G swap, signal quality on SIM1 is terrible (tested in comparison with wife's iphone6+ with same carrier same location) and often i lose signal on SIM1. Definitely not a work phone in this way. any idea? can a full reset improve the situation?

Please ensure firmware is updated to latest version. Next please try performing a hardware reset including cache wipe partition. http://www.asus.com/us/support/FAQ/1011956/
If the problem continues then it may be a hardware issue with the SIM slot and will require RMA service.
Sincerely
ASUS_USA
[email protected]

after few weeks i can say more about this issue, on SIM1 the 4G slot. (stock phone updated and wiped completely)
1) carrier signal reception has now slightly improved with .59 and .63 update
2) problems on switching from 4G to 3G still there, when 4G signal is poor the phone is not able to detect it, and tries and tries and tries sending data to nowhere. after a minute or so, switch to 3G happens and i got network connectivity again
3) comparison with iphone6+, samsungS5 and sonyZ3 (same network, same location) is still terrible, while i got no network, iphone does and loads the pages, slowly but it loads the full page. i think here is the price difference between the two -> antenna, radio, optimized software for any signal condition
4) under bad (bad from a 551ML point of view) signal conditions the battery drains a lot more faster, and that's fine but at least i would like to use the phone, to receive calls, messages, whatsapp and so on.
5) during a call on SIM1, it still happens that signal disappear and i the call is dropped, less frequently than i had before .59 update, but still happens.
6) i'm calling using SIM2 BTW, SIM2 on 2G has no issues.
i will be soon able to compare with honor7 (it should have a very good optimization on the radio part) and let you know.
bye

I am on AT&T in the US and having a similar problem and hoping someone can help except for me it is SIM 2 that is the problem and for me it is at home. Last night I was on a call that kept dropping, and it was not a good thing at all and I had to end the call. I pretty much cannot sustain SIM 2 calls in my house but SIM 2 elsewhere is okay; calls on SIM 1 are perfectly fine and with my previous phones (Note 3, iPhone, Windows Lumia 1520) no reception problem history ever at all. So this clearly is a device issue and not an AT&T issue as I get good coverage in my house. I had two phones up until a month ago when I opted to consolidate by getting the ZF2.SIM1 is perfectly fine most of the time-I've never dropped a call although a couple times I have to say I've not heard as well for a moment as I could, so I question if my house and the Zenfone2 are a good match, although that is really a weird thing as I live in a major suburban metro area that is not a coverage problem in any way shape or form with any dead spot problems, so I am wondering if something is wrong with my hardware and I need to exchange my phone. I'm going to have to pop my SIM 1 back into my Note 3 in the interim and forward calls on my second line in the interim in the meantime if that's the case . (my windows phone takes a nano SIM) and send my ZF2 back for an exchange Should I do a hard reset? Why would my house be a problem? It's not a dead spot area or remote or anything like that. I really like this phone already got a new SIM 2 card once before when I had problems at first but it seemed to be better until I then tried to make a c all yesterday and it wouldn't work.Could my phone be defective? Hard reset?? My software is up to date.

After latest updates and various test i can say that signal coverage and battery life has been improved so much. Thanks a lot asus, it's a pleasure to work with this phone now. Keep doing the same good job!

Glad to hear things worked out for you. My situation didn't work out. I just returned the Zenfone yesterday. I had gotten the replacement phone through ASUS, still replaced yet another SIM card, and the problem with my SIM 2 persisted and got even worse. For me, the SIM slot being 2G did turn out to be the destructive feature of the device. My area is too upgraded for it apparently. You're the only other person I've come across that has referenced SIM 2 usage to me, so I get the sense that most people are just using the ZF2 as a single SIM and don't have a second phone line or data line. Therefore I can understand people being happy overall as it's a decent device for a single SIM user. You are lucky that your SIM 2 coverage is good everywhere. Mine was good in some areas but certainly not in and around my house and there my SIM 2 was unable to sustain phone calls. I didn't care about data-I only wanted phone calls but I couldn't do calls even.I had no cellular connection and my SIM 2 would X out and drop off all the time.
I never had a problem with SIM 1. I always got calls just fine and I found that ASUS always provided updates and I noticed changes in battery life. I was pleased in every other regard but the very purpose that I bought the phone for -to be able to get calls to both my phone lines. I do think ASUS dropped the ball with the 2G slot and need to make their next model with both slots supporting LTE. They me might get me back as a customer if they do.

It looks like I am not the only one who has the sim 2 signal issue. My phone has this issue from day one, the signal of sim 2 just comes and goes all the time. Software update doesn't help at all. I've also tried putting a new sim card, but still have the same problem. I think this is a hardware issue.

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:

No signal/network on my note 5
Hi everyone, so I just got this note 5 N920P last two weeks but I noticed its OS was lollipop...waited for updates for 7.0 but nothing so I went ahead and downloaded Odin with latest firmware from samobile and did it my self, now here the problems start to show first of all this hands free...
forums.androidcentral.com
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 Horrible signal connectivity?

Hi all, I just recently bought this pixel 6 pro a few weeks ago and I've been having horrible connection issues. The main one that plagues me is when all of a sudden, for no reason, I lose mobile data connection. I have some bars of signal with the LTE or 5G icon but with an exclamation point in it. Or sometimes it just loses signal randomly like in the screenshot below. Both screenshots were taken minutes apart.
I've noticed this was an issue for most people and have posted about this here, but I haven't seen anyone complain about it recently. Is there a fix for this problem?

Unfortunately for a great manu people, myself included this phone has garbage reception. There is no known fix.

My troubles began after I updated the phone to A13 enrolling to Beta and then leaving it.
The problem was that the phone will be stuck to H+ all day although weI have good coverage of 4G and 5G in town. Sometimes the connection would just drop and I had to engage flight mode to reset it.
Yesterday I decided that I had enough and did the reset of network settings. Today I have noticed that the problem was solved. Now I have 4g and 5g as in the past. But the problem now is that the Internet just would not work from time to time although it shows full bars. Had to use aeroplane mode again today about 3 times.
It's very annoying to say the least. Had thoughts of changing the phone. Not even speaking about heating issues when on mobile. Horrible.

i agree, terrible signal problems, all time. I`ll try to reset all network settings
for me it`s a disrespect from google to treat all final user like beta tester

Same here. Super slow connection even in areas with towers close by.

Been having this issue ever since I updated to Android 13.
Having only had the phone for 2 weeks, I took it to my provider who said all they can do is return it to Google. With both my eSIM and my physical sim dropping out together, apparently its an RIL problem. They did say that if it's just an issue with one SIM card, replacing it will fix it.

I think this can be solved downgrading to android 12.1 dev you can downgrade to android 12.1 without downgrade bootloader it's safe and don't brick your device because it's a android 12 that runs over android 13 bootloader. Keep in mind that this will erase your data permanently! Do a backup before do it

This has been happening since the phone came out. This is due to the old modem they are using from Samsung. There is no fix.

My coworker has this happen with his 6 Pro, while my 6 is perfect ironically. He has verizon, I got tmobile. He has to leave the store to make a call, but I don't. This has been for the last 6 months though

Had the phone sent away to Google for repairs as the issue ended up happening when I was showing my provider. Got it back and Google said there were "no issues" with it and they couldn't replicate it with either SIM type. Either they put out a hotfix or it magically went away, but I'll see how it goes after using it again.

If you've got another phone (5G compatible), you can try to see if the problem is the phone, or the actual network coverage.
Also, something else you could do is switch to 4G and see if the problem persists.
The thing with 5G is that the coverage is really spotty. That's in general. I don't live in the US, so I don't know what the actual coverage is over there. But that's a general thing with 5G. It cannot penetrate as well as 4G, and even worse than 3G or 2G. When you increase frequency, you lose distance (coverage). So basically 5G needs a lot more repeaters to get proper coverage.
But you could try another phone in the exact same area. Oor..try to switch to 4G and see if the issue still occurs. You could also call the carrier and ask if they have any idea why is this happening.

Same with me. I keep 5G turned off for a couple reasons.

2. 4G is fast enough for me.
3. Better signal.
