Phone reports really weak 4G signal strength compared to the previous version 5.0.0.72
Now at working place Espoo keilaranta, using Elisa 4G reports RSSI 2% and Cell RSSI 59%. Speed is fine, speed test gives something like 90/40Mbps so I suspect that reported values are not correct. Home at Helsinki reported value is better ~75% but it used to be almost maximum before update.
Please read the Release Notes before installing an update.
Bugfixes:

Network signal strength reporting fixed

Yes, I did read the release notes, but I too only have one bar of signal strength all the time on my Sony Xperia 10 iii and 10 v phones all the time. It does not vary, ever, even when I stand next to the cell tower in the centre of town where my iphone 14 reports 5 bars of strength.
So either the Xperia phones actually do have lousy signal strength, or the fix didn’t actually do what it was supposed to do. Even with the change in strength reporting I’ve noticed no actual change in performance of data or voice on either phone, which presumably is to be expected.
I can confirm that. Where I used to have 2 bars of 5, I only get one now.
Same on Xperia 10 II.
Same here on Xperia 10 II and 10 V.
On Xperia 10 V before flashing on Android the signal strength was very good and it was using 5G. After flashing, in Sailfish the signal strength was only 1 or 2 bars and mostly 4G (only rare occasions 5G).
I’m so relieved to see that I’m not the only person experiencing this. I was concerned it was T-Mobile USA or something.
I posted my initial email in the 5.0.0.73 thread. It now appears to be more appropriate here. I’ll copy/paste the pertinent parts in this message:
…signal strength post-update to 5.0.0.73 was dramatically weaker than prior.
Cellular phone conversations sounded great to me, but consistent reports from other participants was that I sounded like I was under water.
I ran CellMon and noted that the two RSSI values used to be high percentages, but now the Network Registration number is very low, while Network Monitor remained high.
My son also has a 10V and has not yet updated his phone. With both phones side-by-side, he gets 4/5 bars, I get 1/5 bars. In CellMon, I verified that the upload and download frequencies utilized are the same on both phones.
I have done many things on the 10V to troubleshoot, but I am traveling tomorrow for work and really wanted my phone healthy again. In an act of desperation and to be thorough to report here, I moved my SIM card back to my 10iii.
I took screen snapshots of CellMon where the 10iii is currently located. 72% and 71% while in 5.0.0.72.
I then upgraded it to .73 and that upgrade also went smoothly. However, the same phone, 30 minutes later now shows 10% and 74%.
I noted in the .73 description that in Bug fixes section > oFono > “Network signal strength reporting fixed”
I theorized that perhaps the Network Signal Strength numbers weren’t accurate before, but now they are accurate. I could live with that as an answer, but the call quality has markedly decreased commensurate with the new Network Signal Strength numbers.
I have travelled by automobile for over an hour, passing through multiple cell/mobile towers on expressways (i.e. towers all along the road…pretty much ideal line of sight and proximity) and I never get above one bar of signal strength indicated on the car’s dash as reported via the BlueTooth connection between 10V and the car. Consistently, the other party on the phone call reports the terrible connection, as well.
[new info]. I traveled from Chicago region to Los Angeles area. I am in a hotel on the 7th floor and have clear line of site to the cell tower a short distance away.
Looking at CellMon, I have 100% Cell RSSI in Network Monitor section, and now a reasonable 60% in Network Registration RSSI and the call quality with Bluetooth headphones has been clear to all participants. I also note that Band 4 frequencies were used in my testing back home near Chicago, and where I am currently is also Band 4.
It seemed there is room for improvements then. On some devices the old code gave way too high signal strength but it seems now it’s the opposite on some devices. I will do more investigation and try to find a fix that would make it more accurate.
I’m having the same problem with my Xperia 10 II and my wife’s Xperia 10 III, both with Vodafone. Since updating to 5.0.0.73, the signal strength is very low.
I just received the SIM card from my new phone provider. For now, I have inserted the old SIM card into slot 2 and the new SIM card into slot 1. Now SIM 2 is showing 3/4 signal strength again. The new SIM card (also Vodafone) in slot 1 now has low signal strength. Can anyone confirm that this is due to the SIM1 slot?
Same issue here on two 10III recently updated to .73, the issue was not present before the update.
The icon indicating signal strength does not change at all, it’s stuck at one bar above zero.
Both phones use german O2 4G network.
Let me know if more context info or logs are needed.
This is only because SIM1 is operating in 4G mode and SIM2 is operating in 2G mode.
Same happend to my X10III. Only one bar of 4 before update.
My experience on X10 III: On 4G, the signal strength shows only one bar. On 5G it shows good strength.
Ahh, the mysterious 5G on the X10 III. It eludes many of us…
I don’t get it here in Australia on Vodafone at least
Now that you remind me (and I have checked settings are ‘Prefer 5G’), I don’t get 5G at all either - even when I’m in London where there is a strong 5G signal in most places. Although I don’t of course know if I’m actually not getting 5G, or the status is simply not showing I’ve got 5G when I actually have …
Same on my X10III. +chars
It’s been almost a year since I was in London (if I recall correctly) I could sometimes register 5G by toggling network connectivity (UK Vodafone Contract), but as soon as I used the phone the connection indicator changed to 4G
Why does a saifish phone needs to have 5G? Doesn’t that also increases battery life? Can’t I use almost everywhere 4G? I don’t think that speed is important.
It doesn’t have to have 5G, it’s just that Jolla has decided to make 5G available for some 5G compatible phones they support, specifically Sony Xperia 10 ii, iii, iv and v.
And yes, 5G does reduce battery life. On iPhones Apple has made it so that you can specify 4G use for most of the time, only auto switching to 5G when absolutely needed for speed or download capacity reasons.
Why not? It’s 2026 and many people are used to 5G speeds for the last 5-10 years or so.
Seems weird to me to have 5G network available, 5G capable device, and asking why sfos should have 5G.
Yes it does drain battery, 4G drains battery, using the phone drains battery, even not using it drains the battery.
That’s why we charge our devices
