Cellular SIgnal Reception - Sony Xperia XA Ultra Questions & Answers

Sensei(s) its been months since this problem in signal reception surfaced, any update regarding this troublesome issue? Can we say that it is a software and not a hardware? If so what can we do about it? If it is hardware, what repair should be done.
Been suffering on this issue for months now.

Bad reception, but can it be fixed.

Hi,
Some of you, like me have a bad reception with their Hero. For mee, it so bad that 3G is more of a ghost than a reality. Since I'm not that into the OS and what is possible with it. Can anyone confirm that it is possible bij tweaking the Android software, the perception can be inproved, if not that I will return the Hero.
To be clear I mean, can HTC do anything about it without changing the hardware.

This will probably be fixed in the future with a Radio release from HTC, it's usually just software releated.
Same issue for me, really the only issue that concerns me - at home hero keeps losing signal, wheras my tytn2 has 2 or 3 bars. Same difference in work - at least it has a signal there.
This needs addressing as its a very week signal compared to all my old handsets, hopefully like mentioned it just needs new radio coding.
same story here
i don't know what's happening .. no signal most of the time

I also have problems getting a good 3G signal when I'm at home, so I just set the phone to connect only to 2G networks.
Usually 2G networks are better spread out (because they're older) and get better reception.
I assume that most of us have a wireless network at home so 3G isn't that important anyways at home.

[Q] Network registration issue?

Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers

Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.

Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.

Poco X3 - problem with signal strength

Hello all,
I started to have some problems with signal strength.
It's not ROM-related (currently the newest CrDroid).
If I cut my WiFi and set the phone to prefer LTE signal sometimes I'm not able to use data. It's constantly switching between LTE / LTE+.
Sometimes it will connect and it's fine but most of the time it isn't.
It only happens in places when the signal is poor.
If I set the phone to prefer 3G it works perfectly normal.
My gf got the same phone and didn't experience that issue.
I believe that for some time after I received this phone it worked normally.
Maybe it's firmware related issue?
I heard about an issue with the poor signal on this phone...
Thank You in the advance for your answers.
