Android 12 network performance - Google Pixel 4a 5G Questions & Answers

I noticed a decline in network performance on T-Mobile after the Android 12 update. Anyone experiencing the same? Went from 100-500Mbps down to 10-60Mbps.

[Q] LTE signal?

I was on MOKEE 4.4.2(release) for several months and had a VERY good LTE signal. I decided I wanted a little change so I flashed CM 11. I noticed my LTE signal was very weak. It seemed it was ONLY my LTE signal. Were I would typically have full bars on LTE (5 out of 5) with MOKEE, I would only have 2 to 3 bars out of 4 on LTE with CM 11 sometimes it would go as low as 1. I also verified with speedtest that it DOES impact my speed. After some research I found this is a common issue with certain CM base roms with no solution I could find. My question is for people that have experienced this issue. Which ROMS (prefer kitkat) does not have this issue? I can verify for anyone else curious that I did not have this issue AT ALL with MOKEE 4.4.2(release). I can also verify that I DID HAVE the issue with PROBAM as well. I think if we made a list of all the roms and how the LTE signal was it could be very helpful for people in the future. Thanks!

issues with mobile signal and connectivity

I have noticed that since 4.5.0 and now OB 18, I have received multiple complaints from people trying to call me saying that they are not able to reach my number, when I am in my home.
The same people have been able to call me and talk to me everyday before that. I don't know if this is a network provider issue or some issue in the software.
Although if it is a network provider issue, then this should have been happening in any version of OOS before 4.5.0
Are any of you facing the same or similar issue?
Network provider : airtel india (if it matters)
Install your old os rom then see is there any problem or not. If there isn't any then update your phone again. This happened maybe because of a slight error while installing thr the new software

Network signal restarting randomly

I updated my phone yesterday with firmware provided in asus website.
Now I'm facing this wierd issue, My network gets restarting like every hour. I can't play pubg as well as stream as i am getting this network issue.
BTW my both networks are in roaming and in 4g with volte enabled
For precise the problem is like "disabling and enabling both sim cards at the same time".
If anyone have solution write that down.
Thanks in advance

I'm facing this problem in android 10 only.
Also my ping in pubg increased from 60 in android 9 to 170 in android 10
Edit: i tried network reset also but nothing works. I'm from india and I'm using Jio and Airtel. I found that DSDS (Dual Sim Dual standby) is enabled (in engineering mode *#*#4636#*#*) and i cant turn that off.
I'm getting this popup "changing this needs restarting the phone", when I gave ok, Nothing happens. When I restart my mobile manually DSDS is still enabled.
I'm thinking about going back to pie, but I am too lazy to back up everything
Downgraded to android 9. Everything is smooth. 40 ping in pubg never goes over 80. No random Network restart.no bugs.
I believe there is a 4G bug with A10.. I have the issue where mine switches from Band 3 to Band 1, and the network speed basically halves causing stutter and lag and sometimes games drop out with no internet as it makes the switch.. The network priority is supposed to keep on the fastest band (as it does on A9) but it switches to the slower band in A10 for some reason... Currently Anders_Asus (asus tech support) is looking at it. I've sent several logs showing the issue..
To diagnose the issue - download speedtest app, then put the phone in airplane mode. Deactivate airplane mode and run speedtest repeatedly - you should see the high speeds for around 2-3 minutes - but after this time, you will notice the ROG2 switches band to the slower band, and your speed drops dramatically.
If you can replicate this issue, I am very interested to forward this Anders @ Asus as well to provide further backup to the issue.

Not thinking of updating to A10 again, No stable network, not able to turn off DSDS. Also, I don't like full-screen gestures on A10 as some third party apps don't natively support it. Waiting for android 11 maybe..

Slow internet speed on S20 FE 5G

Hello there,
I am not getting good data speed on S20 FE 5G . When i put same sim in old HTC U11 and Pixel 3a XL then get double speed eventhough they are old phones . I tried to toggle 4G only but still its very slow internet epsecially indoors. I also did reset of network settings but still did not improved internet speed. Any solution? I like everything else about this phone but this issues is irritating and i dont want to send it back just for this issue
I recall that carriers have different network connection settings for each model of phones. So it's not actually 'fair' to compare those devices.
I suggest you talk to you carrier and ask for help, or you can also submit error report to samsung members app > get help > error report after reproducing the speed issue once more.
Could you share the device model number and the software version it's on?

I tried all possible setting my EE network(UK) suggested to me and even created a new access point but it did not make any difference. Model Number is SM-G781B/DS and is android 11 running the latest nov security Patch. Another funny thing is that there is often 5G that appears on the phone signal bar when the speed is less than 1MB/sec. I don't know if it's just me or anyone else who also gets less speed in comparison to any other android phone. I use fast. com and Speedtest to know about downalod and upload speed

5G icon could appear but in reality still be connected to LTE, some carriers do that.
anyway, data related things will have to be taken care by the carrier side but sounds like you're not getting a good care...Idk what to tell you since i'm in the US region. Idk much about what sort of help you can utilize in the UK region.

Question Benefits of the Samsung 5300g modem over the Samsung 5123 modem?

I had poor signal and stability with the Samsung 5123 modem in the Pixel 6, and the updates never solved my issues with mobile network standby using about 30% of battery charge. I anticipated significant improvement with the Samsung 5300g modem. I've only tested my sim briefly, finding signal strength is virtually the same. Does anyone know whether signal strength would be expected to be unchanged, and it is only the stability that is supposed to have improved?

no there is definitely an improvement...My data is much more stable now, in spot where it ussually lag, and 5G is much stronger, less drop to LTE.

Definitely a change from my p6p, my p7 just works now, no signal drops and seems to be stronger, reliable now, I still have my p6p, so later I might run a few tests to check strength and speed
