i thought this would be the best place for a problem i started having about2 weeks ago. i am on vodafone uk.
i used to get 3-4 of the 4 bars reception while sitting at home(as an example). suddenly i was getting 1-2 and sometimes none (all blank).
i thought i would try and eliminate things one by one so here is what i did...
checked with my sim in another phone and another sim in mine. from memory the other phone having my sim was slightly down but not much and my phone with the other sim didnt really change much.
i checked with vodafone by calling them, they said they couldnt see any problems on the network, birmingham uk, but would send a new sim, after getting the sim activated when it arrived, no better. their onling forum is still waiting for a response back from their technical whether there is any problems. i dont see how the phone department can instantly tell me when the technical need many days to find an answer.
i thought it could be the rom so i first updated lite'ning rom to resurrection remix and then to a later version of RR and no change. the newest version of RR has a different kernel, flux i think, than the siyah in the 2 previous roms but again that different kernel didnt improve it. lastly i even changed the modem/radio trying to different ones to the default, xxlpx and kh3 and again no difference.
the only thing that improves it is turning 2G on instead of 3G. the bars go back up to 3-4. even with 3G on previously as i never changed it before it was always fine.
i know this is a long post but i wanted to be thorough as i really appreciate any help as i am now lost as what could improve this.
Mispost
anyone?
I have been having a similar problem on Three for about five weeks now. Despite numerous reloads of Android and modems etc I was getting no results, 5mb dl speeds have dropped to around 150kb despite having a good signal.
After many many calls to so called customer service I have discovered that a new cell tower near to me has been activated as part of the network expansion program and because this cell is closer to me than the one I used to connect to I now get a stronger signal from this so my phone always chooses this. Problem is this cell has only got a 2mb feed INTO it, its a TMobile/Orange cell now being shared with Three....so I am basically fooked.
Check with Vodafone if they have done anything similar recently near you. Three are adamant there are no problems my end, technically they are correct I suppose, its all working, I just cant access the net without it timing out constantly now.

I am having the same issue with my phone. I get only one bar (sometimes none!) whenever I'm home & I'm on WiFi; however, I get full signal strength when I'm out & on 3G.

i thought it could be the cell tower thing as there is only 1 vodafone one in quite a large radious, about 2 miles, and many of all the other networks. i dont know why vodafone are happy to have 1 compared to at least 3-4 each for all other providers.
this morning i drove that 1 mile to the vodafone mast and ran fresh network and surely that would have connected to that as i was 5 meters from it. still no better. ??
Just try NELP3 modem once... I had done similar issue once.. Now my network is better..
is nelp3 okay for uk though?
Try flashing another Modem. Im from Germany but i had similar problems. A new Rom would do too i think

not sure what you mean with 'all'
Number of options, tower may be having problems, maybe some form of interference, try a different modem, try different sum card if you have one spare?

i do have the same problem as above, no signal in the building and 50% signal outside building. I swithch my SIM with fren's (he use another telco), and his SIM not work on my S2 and my SIM work on his phone (not SIM issues).
I tested many modem as recommented , LP2/LP3, LP9, LPX, KI3, KI4, KF2, no luck.
I flash different ROM, (some old version that work before), from CM9, AOKP, Sammy. no luck.
I restore old back up ROM. no luck
Fix permission, no luck.
any advice ?
OK next step is to flash a different modem
Sent from my GT-I9100 using xda app-developers app
i've tried a few modems including the ones people believe better, all have this problem so far.
it may be the network mast in my case. i discussed with vodafone what 3G mast i was connected to and then which 3G mast is next closest. i then went right next to that other 3G mast and the signal was full bars, no fluctuation at all. this surely means it is either, 1-the network mast i keep locking to having problems or 2-all the modems i have used favouring battery over strength and not getting enough power to get a good signal.
is there a way of finding out which modems are better for battery and which are better for signal strength?
Umm not that I know of, best thing to do for that is either research the modems for better strength or battery etc, or just test some yourself, however that is time consuming,
Personally I think it is just the mast having problems, however I may be wrong
Sent from my GT-I9100 using xda app-developers app
i thought i would add a little research to this thread, not too much but just my experience with 3 specific modems.
the background is that recently i have started getting very poor network signal as i believe the closest 3g mast to me is having problems. if i turn to 2g its better as the phone then connects to the closest 2g tower which gives better network signal.
i know that a modem should be left for 2-3 days before judging but i thought that if a modem is currently better than another then that is only likely to stay the same with time as long as they were given the same short period of time.
i used the app network signal info and did 3 5 minute tests for each modem and then averaged the percentage of the signal and also averaged the -dbm also.
i first used the modem i currently had on there, BUKI1
- average percentage was 19%
- average -dbm was -103
both very poor scores
the signal was very jumpy up and down also
i then flashed the custom modem, i think by krs007, M250S
- average percentage was 44.6%
- average -dbm was -90.66
obviously a huge increase
the signal was very steady, hardly changing from that average
lastly i flashed NELP3
- average percentage was 30.66%
- average -dbm was -97.33
better than at first but not as good as M250S
i am now going to let M250S bed in for a few days while keeping my eye on here for how NELP4 performs but so far i have a huge increase in signal in a previously very poor area. as this is also due i believe to the tower having problems, hopefully it will only get better.
Try downloading OpenSignalMaps from Google Play Store. For starters, you can determine the approximate location of the offending cell tower (if the cell tower was indeed the culprit). Sometimes, i realise that the phone tends to stick to certain cell towers when others are in closer range and could purportedly provide a better radio link. For this, the app provides a refresh feature that allows you to manually trigger a cell tower refresh. I am aware that most apps requiring connectivity have this feature but i don't suppose you can call the refresh on trigger.
Hi Marc
Tracked down a copy of M250S(dont know if its the same as you have installed though), and very briefly, as in 30 secondsish, I had 4 bars and dl`s around 5mb again!.But midway through it dropped out and that seems to be the pattern. Seems to be having problems locking onto a cell, signal bars frequently grey out, maybe its a compatibility issue with CM9, I dont know.
Anyway, let us know how you get on,
Cheers
Chris
it probably is the same as i dont think any others have that name.
it probably just needs to bed in for a few days. i have noticed mine go between 3g and H quite regular but it always does that, i havent had any dropped calls or similar so far.
I am using an AT&T Atrix 4G (rooted and has NottachTrix ROM with 37p radio) in India on BSNL AP circle and I have been getting really poor reception. It is so bad that I can only receive or make calls about 25% of the time. Many times, the phone shows no signal, but often it can't receive or make calls even when there are full bars on it at that moment. I tried using the other popular radio posted here, which is 36p and that showed no difference. Is there another radio that is better suited for this region and mobile operator?
I also have a severe battery life problem. With a brand new battery, it lasts about 24hs on standby, but even with a bit of usage it will not last full day. Sometimes it goes from around 60% to under 10% overnight (in 8hrs or so). I am using JuiceDefender for maximum battery life, and also verified with CPU Spy that the CPU is going into deep sleep as expected. Battery usage always shows "Phone Idle" and "Cell Standby" as the biggest battery consumers. Perhaps, the same problem that is causing bad reception is also causing the battery to go down quickly? I bought it as a used phone and used it on T-Mobile for a few days before leaving US. The battery life was terrible then too, but I thought it was because the battery was getting old, so purchased a new one before leaving.
Even though the reception on T-Mobile was also bad, it was nothing compared to what I am seeing here. Besides, T-Mobile didn't have a good coverage in that area anyway, so the reception was just like most of the other phones I tried there. My guess is that there is nothing wrong with the hardware itself, and the right modem firmware will fix both issues. Could someone who is already using this model in India, preferably with this mobile network comment?

Been using the Atrix for the past 6 months. Have used in AP Docomo, AP Vodafone and Chennai Aircel networks, Reception is top notch.
Everyone knows about the quality of BSNL signal and your problem lies there, IMHO.
Battery life is also awesome.
I used CM nightly and I do not overclock. I found faux kernel to be draining my battery so not using that too.

Interesting... I have heard people say bad things about BSNL signal, but I didn't think it would be this bad, so I was still under the impression that the issue is with the phone. May be I should borrow some dumb nokia phone from someone and confirm/rule out the issue with signal quality
I have't tried CM yet on this because I wanted the blur functionality for the dock, but I am not finding much use for the dock, so may be I will switch to CM one day, if only the support for biometric scanner is added. Thanks for the helpful reply!
Well, since the signal is always alternating, it increases the battery usage, i think
Well, my first concern is the reception. With full bars showing up, i am some times unable to make or receive calls. If his can still be BSNL issue, then I might just have to switch. When the phone is in this state, I have occasionally tried to see if restart would fix it, and though I can't confirm it 100%, I was almost always able to make a call immediately after the reboot. The reason I can't confirm that a reboot fixes he issue is because, there is obviously a few minutes of gap between that might have had external change as well.

Support for the fingerprint sensor is already present in Cyanogenmod 7. Give CM7 a try. The phone is smooth and rock solid.
And as ticiano_arraes suggested, poor reception or network quality has a direct impact on the battery, as the phone keeps trying to get hold of a stronger network.

Nice, I would love to give CM7 a try. Is I said earlier, I am less concerned about the battery life than the reception, as 3 out of the 4 times when I want to make a call, I don't get the signal immediately. Also, callers complain about not able to reach me. This is not my primarily line, so I am able to somehow manage so far, but if the problem is definitely on the network side, I will consider switching to a different service. In any case, I will try CM7 and report back.
What band are you using?2g or 3g?never set it to auto.Set it to GSM ONLY
I use atrix with bsnl 3g sim, cm9 Turk,radio is 100R don't have any signal issues or battery drain if I am using only calls I switch to 2g only otherwise 3g only mode use lot of data if I switch to auto or other radios I had lots of issues but with 100R no issues good signal as well as good data speed so pls try that using for nearly 9 months without issue
This is what I have right now:
- Select network - 2G Only
- Operator selection - Select automatically
I don't have a GSM Only option anywhere.
First try 100R radio I too call& battery issues then switched to this radio now don't have network issue when using 36& 37 radios most of the time my mobile was not reachable even when signal was showing do u use data? If not select 2g only using power Widgets u can easily switch 2g or 3g mode easily try 100R with nottachtrix it was good & if u r interested try Turk cm9 & 100R it gives better battery life than others comparatively

Thank you, will give that a shot now. I found the 100R download link from here: http://forum.xda-developers.com/showpost.php?p=21525149&postcount=8
That post also mentions 30p, did you try that?
I got my mobile with .30 then switched to 36 got severe battery issues & switched to 37 it will show signal but mobile all be not reachable then switched to 100R never looked back try with ur current rom check difference.
I'm on .30P and JB epinter's CM10 rom and signal is top notch, no reception problems, battery life great, from INDIA on tata docomo

If you have the stock ROM it's probably that the main problem is the radio that you are using right now. The radios control the way the antenna communicates and all that stuff. So if you are having bad reception, the antena is searching constantly and making more effort to keep you alive on the mobile network.
Try flashing a new radio, it's too easy. Just find in the forum a radio for your region( but it could be from anywhere, for example i'm in Finland right now but i use the normal att{usa}).
I read that you are using just 2G, that's great for improving battery life, but don't expect a huge amount. I always run in 2G and in HSPA+ when i really need the gps, fast info, etc, I'm always syncing with FB, Twitter, Instagram, listening to music and barely it last a day withe the extended battery(bh6x).
Hope this works for you
btw, ,flashing a new radio doesn't delete the data of your rom, it's so easy
I have now observed the signal quality over 24hrs with the 100R firmware and I think there is marked improvement in quality. There were times when I had no signal and I couldn't make calls, but at least I didn't have a situation when there were bars showing and yet the call didn't go through. Obviously, I need more time to see if what I am seeing is genuine.
On the other hand, I don't think the battery life increased significantly. With very light usage, it went down from 100% to 22% in about 23hrs and 70% of that is in Phone idle. I have attached 3 snapshots taken at different times of the battery usage to show what I mean. May be it is just the stock kernel not fully optimized, so I will give CM7 a try.
I installed cwm touch recovery 5.8.1.8 and wondering if the backup created by this recovery is complete enough for the stock rom so that I can switch back to it if CM7 doesn't work out.

Does this ROM also support biometric scanner? What would be the biggest reason not to use it and go with CM7 instead? Stability?

No, this ROM doesn't support biometric scanner and the stock Camcoder cannot record videos due to Nvidia Driver Issues (3rd party video recording apps work), apart from that sometimes random reboot, rest everything works like WiFi Hotspot, GPS is great, and instead of staying on GB I'd like to stay on JB with these few quirks...

Hi all! First post in the Alpha section... Got my Alpha the other day. And i love all about it. But there is one thing thats gets me wondering. It's the reception. All my previous phones got good reception at home.. i get 1-2 bars. So my question is. Does anybody experience this issue? I have experienced SMS delays and chipped calls.

Provider : Telenor
Look at actual signal strength in dBm. Bars are arbitrary and vary from phone to phone.

It could just be a faulty device... I'll try replacing my sim first. If that's the issue.
If that's not working. I'll have it replaced.
Edit: Had my sim replaced. Still experiencing bad reception. It goes as low as -105dbm... where my z2 had around -70 (same network, same location)... that's bad. Any ideas what I can do to solve this?
Yeah keep me updated - my Alpha also seems to have noticeably weaker reception than my iPhone on 4G (800mhz band).
Hoping its a modem firmware/software power output thing and not a hardware thing.
Same here, looks like the reception is 1-2 bars worse than other phones.
But I have no experience of delayed SMS or failed calls and the speeds on internet is very good.

Signal problems
Hi, I'm on my second Alpha and first sim, I have an alternative sim yet to try but have chated on Twitter with another user who found no improvement with a new sim and changed phones completely. I'm with three. My signal goes completely when I'm sitting with other three users whose phones work fine. I think it's a phone fault and am considering sending it back now.
Hi guys,
I noticed something interesting with my Alpha:
As you, I have a poor signal strength. But when calling someone then the signal bar jump to full force instantly!
Could it be a link with BIG little technology?

Well, for those who have the same problem, I deactivated the 4G. Then the signal strength is better. I made the test: 2 bars with 4G enabled in network settings, full signal when 3G only.

The alpha is my second LTE able phone. Both showed a completely different signal bar reading when using LTE (and checking in lecture, how Signal strength is meassured for GPRS/EDGE/UMTS/LTE it shows, that LTE uses a completely revised scheme to calculate the signal strength)
I haven't made any speed measurements yet, but my feeling is:
(4G) With LTE, even without any highlighted bar i can use internet, webpages load fast, other lookups work.
(3G,3.5G) With H/H+ , and at least 1 bar highlighted, internet works
(2.5G) Edge and at least 1 to two bars, internet is available... three bars are better for it to be worthwhile
(2G) G only - forget it. I'll need 4 bars to surf the web, and i must wait. Chat works if i'm lucky and got at least 1-2 bars.
Apart from that: the signal bars in 2G and 3G show the strength of the signal - but aren't any measure of the quality of the signal. They show anything that sends on the frequency/timeslot of the 2G/3G signal you're receiving. If you've got heavy interferences, you'll get full bars but it all is static.
(Like - in a disco, you've got loud music, and people speaking very loudly to you - that would be full bars, but not the best place to speak to each other....)
I don't understand exactly what the value used by 4G exactly means, but it sounds like it only represents the LTE cell you do want to receive - so it should be more accurate and cutting out the noise somehow
I think you're right ! This is my feeling too. In 4G calls are always perfect for me even with one bar.
In settings we can also have a more accurate highlight on to the signal strength in Db.
Guys this alpha is full of mysteriousness !
I think samsung did it ON purpose.. ! Save battery??
I have weaker signal too.. on iphone 5 is full and i had on my former Honor 6 full as hell..
But I dont konw IF samsung wants to save power by this .. I think it has no much influence as iphone 5 nor Honor 6 had full signal and battery never got down fast.. when I had Honor 6 100% at night it was 98 % in morning..
Another thing with aplha ,when i leave phone in sleep half hour or longer , th emobile network stops and wont come up...
I have to restart phone or turn airplane on ad off.. then H+ or 4G appears..
I have the issue with mobile data too, it seems to also do it when it has been on WiFi for a while and you change to mobile data.
no service
Hey guys,
I have a very bad reception with my Samsung Galaxy Alpha when i'm in the subway in Paris. To be honnest I have no service, no sms, no calls, and for sure no internet...
I can see people using their smartphones inside the subway without problems.
I had an iPhone 4 during 3 years, and didn't have any problem with it when I was in the subway.
I'm using the same phone carrier "Bouygues Telecom"
So what's wrong with this Galaxy Alpha ?

Hey people,
I'm also having connection issues:
When I boot the phone it's working is at should: Switching between 4G/3G/EDGE etc. After a while the connection sort of times out. I can only make emergency calls. It works flawlessly for up to a day, or it can only work for like 5 minutes.
Rebooting the device fixes this temporarily. My service provider (Hi in NL) has already sent me a new simcard which doesn't help. They are now saying I should send it over for repair.
Btw: When i leave it in CDMA only, the problem takes much longer to arise (like a couple of days).
I can see that people who have posted in this thread are having the same issues. I'm wondering if this is firmware or hardware related, as I want avoid sending over my phone. If it IS a firmware bug, sending it over for repair obviously isn't going to fix this.
I have sent an e-mail to Samsung BeNeLux. Like Simona Simmy says, we should all write to Samsung
Every custom ROM for Redmi Note 4 SD has a bug that is making LTE signal disappear, you can verify it by opening signal info in settings.
You can see that the dBm signal stay at normal value but "asu" value is constantly spiking to "99" which causes signal indicator to show no signal for brief moment.
This happens for every ROM that is not based on MIUI.
Does anyone know what is the cause of it? We have sources released, is this a kernel issue or something else? It cannot be modem firmware since we are using same as MIUI. Can this be diagnosed/fixed ?
I remember it was the same few months ago, and still nothing has changed. I think it's the biggest issue and im wondering if anyone is trying to work on it.
Edit:
Best explanation: https://forum.xda-developers.com/showpost.php?p=76811230&postcount=157
I will mark this as resolved.

Every custom ROM for Redmi Note 4 SD has a bug that is making LTE signal disappear, you can verify it by opening signal info in settings.
You can see that the dBm signal stay at normal value but "asu" value is constantly spiking to "99" which causes signal loss (no signal).

I think latest LOS has this fix approximately a few weeks ago? Have you tested?

I tested lineage-14.1-20170810-nightly-mido-signed few days ago, bug is still here.
Does it actually lose signal or is it just a visual problem?
Might be a carrier problem, currently staying at a flat 49-50 in Singapore on Singtel.

Watch the signal for 5-10 minutes, it will drop.
yeah.. completely agree with op.
Is this fixed or still there?

With the data on? I don't have issues when data is off but when on internet, every few minutes, sometimes every few seconds i lose network and data transfer for a 10-15sec
LOS last weekly 24/08 and i have this problem. Is there a fix for it?
Bump - Any fix? What firmware?

You need to enable LTE and Data.

I don't understand your reply.
LTE and data are of course always enabled on my phone.
The only moments where I lost LTE signal is when I drive and arrive at a place where there is no LTE signal.

Yeah. It can be solves, if it's showing wrong signal level
This doesn't look like a cosmetic defect. I was on MIUI Nougat and didn't face any issues with signals. After coming to RR Nougat, I can see frequent fluctuations in network. Lesser speeds, much less consistent connectivity. I have tried changing the sim, compared with a phone running MIUI on the same sim, there is an undeniable fluctuation, with intermittent loss of data. This seems to happen only when data is enabled.

Yes, worth mentioning is that the issue is with LTE (4G) with Data enabled, i didn't noticed any signal issues or disconnections using 3G with Data enabled. Someone smarter should look into this.
Had my x1 for a couple of days now and lots to like about it however I have noticed that it seems to have a very weak phone signal reception.
I am on three in the UK and in the normal areas I travel I have never noticed an issue on my other phones with it struggling to hold on to signal bars.
Anyone else have this?
Signal bars mean absolutely nothing. Many oem even show full bars even when there is actually no signal.
Better install cellmapper app that will exactly show and record the signal where you travel.
Also, do you have 3uk volte working?(calls over 4g network)
Well all I can say is that I live less than a mile from the nearest mast and would nearly always have full signal bars on other phones yet on this phone it drops on and off 1 bar.
I will download the app you mentioned and see what that shows
I've had this problem with numerous Sony phones over the years, always poor signal compared to Sammy's, Pixel's and iPhones that I've had. Same issue with the X1 I have now, always on WiFi calling and no signal, my Pixel 3 XL would be happily sitting on 4G.

Glad it's not just me then.
I do remember having this issue on a previous Sony phone also but can remember the model now. It's been a long time since I had a Sony but thought this one was going to tick every box which it almost does apart from having reliable signal reception which is really should be a must!
Is there anyway they can improve this with software of are we stuck with it due to hardware issues?
I'm in my 14 days returns periods at the moment and like everything about this phone apart from what it should do first and foremost
I am having the same problem, I'm on EE and my LTE keeps dropping from 4 bar's to 1 bar then nothing which causes me to lose data connection. It then jumps to 4 bar's again and then repeats this over and over. This is happening at home where I always have full reception. I have tested my sim in 5 different phones all have full reception and don't lose connection only my Xperia 1 does! Any help would be appreciated.
Same problem for me. I switched my SIM from Galaxy S8 to X1. S8 has 4 to 5 bars while X1 struggles with getting one bar at home.
Ffs... The bars mean nothing. Sony phones take into consideration RSRQ(signal quality) and SINR(s noise) values of the signal. Other oem don't. The actual signal power RSRP (do not confuse it with bars) is same or better on Sony.
Xperia 1 has most advanced modem and antenna setup of any 4g phone. 4x4 mimo even on low bands (first to have it).
3uk and ee are special in the sense that they need phone to support volte to get access to their low band spectrum(band 20).
So make sure you have volte aka 4g calling enabled and check with apps like Netmonster or Cellmapper the band and RSRP of the signal. Then compare it with other phones at the same place.

If it's as simple as that why is it not enabled on this phone already?
I think what you seem to be over looking is the fact that I and others here have said that yes the bars are lower than other phones and flutter slot but also to the point where they drop completely and give no reception at all. A situation not faced on other phones.
Can you explain how we enable this missing band so that the phone can provide a more reliable/stable reception
Does your phone have 3uk volte(4g calling) enabled? Phone should stay in 4g during call. If not then you are out of luck.
ee users can install EE firmware to get Volte working if it's not already . newflasher on xda helps to change firmware.
And please compare signals with abovementioned apps.

If you're having signal drops / dropped phone calls etc... I get it. But Sony is historically notorious for showing lower signals than others on those bars. However, as stated, the bars are pretty meaningless. I've owned many Sony's, and while the bars are lower (sometimes all empty), I still have signal in all the places I should. YMMV.

I don't honestly know. My phone was purchased sim free from carphone warehouse and I use it on 3 network. The phone just set itself up. How would I check this? Is it something listed under network settings?
It's so frustrating as I'm really loving a lot about this phone but just want it to be comparable at least with my other phones I've used with call reception
those who are having signal problem, are you using EE network?
I saw lots of people with EE reporting this issue on official sony forum.
Got mine yesterday from Vodafone and signal is perfect !

Yes
I also have only 1 bar... Orange.
If you are EE UK user, then you need EE firmware on your Xperia 1 to get best network compatibility(Volte and low band support because of it).
3UK users probably need also 3UK firmware but that does not seem to exist yet.
This weirdness of low band access is specific to two UK operators. Everywhere else the device is fully capable of best 4g experience.
Wait Next update

So for those of us on three network but purchased the phone sim free are stuck with the problem as three do not sell this handset themselves so unlikely to release any firmware for it.
That does not look good for me so I think I will need to return within my 14 days.
Shame.
There's definitely a network connectivity issue with the XP1 right now though. This seems to affect only XP1's on the EE network, which were *not* bought from EE direct, i.e. ones with stock firmware. (e.g. mine!)
The symptoms are that periodically, first the 4G symbol disappears, then the signal goes to zero and you've lost the internet. Then it reconnects back onto 4G again. Sometimes this repeats 3 or 4 times in succession. The whole thing takes from 5 seconds to maybe 30 seconds depending on how many re-tries.
You can go for maybe an our or so without a problem, or sometimes it happens like every 10 minutes.
And here's the key part: this happens wherever you are, even on a full strength signal. As far as I can make out, this affects ALL XP1s with stock firmware on EE. EE say it's a Sony problem. Sony say it's a network issue. So we are all stuck.
Does anyone know of a suitable network logging app, which will log 4G disconnects and signal loss, so we can provide evidence to EE and Sony?

(My phone is fine with a Vodafone sim. There's something specific to the phone firmware/config - timers, buffer sizes, packet sizes - whatever - and the EE network. But right now, on EE, it's unusable.)
