[Q] xperia ray signal strength

I wonder if only my ray or all ray's has poor signal reception. Time from time while I'm talking with smb. my call simply hangs up. And as far as I noticed this happens when the signal reception is a bit lower or not very stable. In places where signal is weak (outside the city) my wife's dumb phone Nok1a got better signal with 1-2 bars, while ray no signal at all.
I've was using .42 firmware for a long time, tried 4.0.3 beta, now using MIUI based on 2.3.7 and still have the same problem, what makes me think that's not software related issue.
What about your phones ? Am I only who has this problem ?
Do you both have the same network operator? I can easily say that my ray has better reception than my girlfriends x10 mini pro. Some exterior phone protections weaken the reception as well.

Yes - same operator. My Ray has rubber case on it, but I've checked signal strength with it and without it. No real difference.

All I can say it I never saw a mobile like Ray with such good signals... much much better signals than my HTC Sensation and HTC Desire I had previously... in fact gud signals was one of major reasons I got this Xperia Ray
The Ray has absolutely terrible wifi reception though. It won't even pick up routers when its right next to the phone whereas my Desire Z could from a pretty far distance. Only major let down.

Nope, 66 is the newest baseband! Have a look http://forum.xda-developers.com/showpost.php?p=24650629&postcount=15!
I don't know, whether the signal strength is better now, but the batterylife is much longer!
for me,
sometime the signal is great..greater than other devices...
but some other time, at certain area, it has no signals at all while other devices have it although we are using the same network operator...
but i don't really care about it cuz i think the signals is so much better than my previous device...
My Ray is actually rather poor when going indoor first floor. But once I step outside or going to second floor, it goes 100% instantly.. So..

I had "dumb phone" Sony Ericsson k850i (which amusingly enough used to be called a "smart phone" lol), an x10 and now Ray and they all get the same signal on AT&T in the same places. Most places I am it's full signal, a handful get less... but has been consistent across devices.
I only used the x10 (not mini or pro) as my main phone for less than 6 months (free upgrade w/ contract for refurbished) and still tinker with it but for my hands I felt it was nifty but big and clunky, so I bought an unlocked Ray (2-3 months ago). I've lived/worked and hung out in the same places, so I figure it's a pretty good comparison.
TLDR: no problems with signal for me.
Yep, my ray is having low signal reception too.. that yellow triangle always appears. I think is a hardware bugs to bad. I want too switch xperia P but still don't believe they already fix the bugs for signal prob. and. xperia p is not on coming for ICS in the few weeks later.
I've notice while using the cell tower polling monitor of the Llama application that my Ray drops the signal. It shows in the log as Cell: -1:-1:-1 (ignored) No signal/Unknown. I live and work in a big city were the signal strength is very strong and were there are 4 to 6 cell towers all around me (at work or at home).
The lost of signal is very short (a second or two) but actually drop a call once.
I have base band 203028D-64 and running Android version 2.3.4.
Since I don't want to update to version 4.0.3 as there is too many people complaining about lagging problems. I will try to update the base band to 203028D-66 and come back here for results with the Llama log.

If you can, update to 4.0.4.
How's 4.0.4? Is it better than 2.3.4? I don't want my phone to be slower and have problems with WiFi connectivity.

Don' remove Sim Toolkit.apk
I have to reinstall ROM due to signal problem after removing sim toolkit.apk
While searching on how to ugrade the baseband for my ST18a, I came across another thread about this issue on the Sony's Forum.
If you go to Menu - Wireless & network setting - Mobile Network - Network Mode and change to GSM only, it will give you better reception.
I have tested and validated it with the "Network Signal Info" & Llama App.
The reception signal improved dramatically and no drop calls yet.
Notice you will be on the 2G network if you have a Data Plan (which is not my case) but you can always change the network back to WCDMA-GSM when you need faster data download speeds.

[Q] Weak network signal

Friends, recently i got xperia neo v and after using it for sometime i am facing a strange problem. I am getting very low network signals. I have tried the same sim card in another cell phone also so there is no problem with either sim card or signals. Network signals keeps fluctuating. I have tried chaning almost every basebands, kernels and roms. Still i am facing the same issue. I am confused whether its a software fault or hardware? Till it was unrooted and bootloader was locked i was facing no problem. After 2-3 weeks of rooting and unlocking bootloader i started facing this issue.

Strange.. IMO, its not because of rooting.. How is the network outside? Where do you find low network, in your home or outside too?

[Q] Signal looses completely from HSPA to EDGE

Hi, bought the xperia Z2 a week back. In my room I get good signal. Sometimes HSPA + but when i go down floor to to the dining area (where i have been seeing poor signal) the Z2 looses it signal then comes back to EDGE after half a minute. My old phone Iphones 4s, HTC One when it lose HSPA signal it goes back to EDGE.
My network setting is on 4G preferred. I have put it on WCDMA preferred still the same problem. On the same network i carried a Iphone 5 and the Xperia Z2, the z2 dropped but the iphone signal stays.
Any way to fix it? or whats causing the problem?

poor signal reception?

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?
More info here:
https://talk.sonymobile.com/t5/Xperia-1/Issue-with-network-dropping/td-p/1376332/highlight/false
(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.)

Question Has anyone else been noticing very poor signal quality?

Been noticing that my signal drops more than normal at home and at work since swithching to the xperia, Used to have both a Note10+5g which would get consitant 5g at full signal, and the same for my Oneplus 9Pro, But with the xperia ill get 1-2bars 5g in the same room if it hasnt dropped to 4G at 2 bar or 3G. Mobile network EE

Just switched from OP10 Pro to Sony and I noticed this same thing. With my OP10 Pro I usually got very good signal, but with Xperia the signal is very poor.
Me as well, especially on WiFi. My router supports only WiFi 4 and I get poor signal if not directly next to the router.

I switched from Nothing Phone 1 to Sony and I noticed this same thing. With my NP1 I usually had a very excellent signal,
Okay glad it's not just me, but I wonder why it's like that now
Phew, I am not alone. Mine works poorly with Wifi 6. Any ideas to fix?
I've noticed this also, and the Bluetooth connection (with Sony's WH-1000XM4 and WF-1000XM3) is also very weak.

I do hope that Sony will fix these soon.
Signals should not be an issue in 2022. However, be aware that the GPS is only a single-band one, despite some specs around the net.

Hi, I just realized the solution.
Please install voWIFI app via play store, disable DSDS, and you are done!
If you totally missed your Antenna, be sure that u are using the first sim slot for your sim card

Same here. It looks so nice with metal case. Call quality not that great also
Metal cases do degrade network signal very much. be it of any kind, GPS, carrier signals, Bluetooth and WI FI.
Sony uses its signal scale in quality, the rest of the companies in power.
I didn't get a 1 IV until the Android 13 release, upgrading from a 5 III. I also use a work iPhone 11 regularly. I'm in the US and my phones are all US market models, and I live in a large metropolitan area. Both of my phones are in carbon fiber cases with metal in them. Here are my observations, which seem to be more positive than what is posted here.
Wifi: My home network is Wifi 6, and the signal on the 1 IV is usually weaker than the iPhone 11. But, it's only by 1 or 2 dbm, per the data from my router. However, if you run a speedtest on both phones, the Xperia 1IV always gives a higher Mbps reading than the iPhone.
BT: I have WF-1000XM3 and M4s and both work fine on both phones. I can get further away from the phone with either headphones from the iPhone than the Xperia, but the Xperia works fine if it's sitting next to me or in my pocket. No issues with connecting to other devices like speakers or car stereos.
Cellular: My 1 IV is on T-Mobile, while my iPhone is on Verizon, so hard to compare there. However, my wife has an iPhone 14 Pro Max on T-Mobile, and in spot comparisons, my Xperia gets better reception and faster data connectivity. When I'm on 5G, my Xperia regularly gets over 1Gbps download speeds, even without full bars on the signal meter.
I am from Croatia and I have very poor 3G signal, 2G, 4G and 5G signals are OK so in my home there is no 3G signal at all and I am not available because my network doesnt have VoLTE. I am on 64.1.A.0.882 firmware. Before I would have signal problems but restart would fix that. Now, after restart nothing is fixed. Till now I reset my phone 2 times and it was on service repair because of fingerprint sensor. 2 days ago everything was OK. I don't know what is going on. Is there any fix? Could this be Google Play System problem? Because yesterday I got another Google Play System update of 9 MB for March and around that time this problem started and I don't see any fix.
I manage to solve problem. I call this code in the phone *#*#4636#*#* and it opens Testing. In there I went to
Phone info --> three dots --> Select radio band --> Automatic
and after that everything start to work. I don't know what radio band was set before because I couldn't read that. I gess that every time when problem happens I'll have to do this.
