Android 10 Dual Sim Performance - Samsung Galaxy Note 9 Questions & Answers

Hi,
I run into a "problem" with Dualsim mode.
Sim1: 3-Austria LTE/4G
Sim2: A1 Austria LTE/4G
The possible Internet speed changes with the connection mode of the second Sim.
For example:
Sim1 always in 4G/3G/2G (automatic)
Sim1 + Sim2 deactivated: 152 Mbps Down / 33,4 Mbps Up
Sim1 + Sim2 2G Mode: 136 Mbps Down / 33 Mbps Up
Sim1 + Sim2 3G/2G Mode: 105 Mbps Down / 15,4 Mbps Up
Sim1 + Sim2 4G/3G/2G Mode: 25,5 Mbps Down / 1,25 Mbps Up
The whole thing is reproducible. The setting has not changed since Pie and worked without problems at the time. Has anything changed on the firmware side? Or does my note have a defect?

Mobile data signal value 4.2.2 changes

Since I installed the ARHD 10 (Android 4.2.2) I recognized some changes with the hysteresis of the data signal switching.
With 4.1.2 I got H every day at the same place with gsm / wcdma auto selected.
Now with 4.2.2 I get G at first (gsm / wcdma auto selected too) , but when I manually switch to wcdma and then back to Gsm / WCDMA it stays at H.
Has anyone encountered the same issue?

Unstable and slow 4g airtel signal

Hey guys i have taken my brothers letv le2 phone. And iam facing airtel 4g signal issues. The speed of the net is very slow as compared to net speed when i put the same sim on my asus device. Also the 4g signal is very unstable. For sometime it connect to 4g then the data connection get lost for 4-5 second ( i think because of shifting to another frequency band i.e. gsm) . When i was using jio sim in letv le2 i was getting the same speed as compared to when i was using it on asus phone. I think reason may be as jio have only 4g bands thats why my le2 was not changing its band to gsm band, and net connection was stable. If anyone faced this problem then please give some suggestions. Should i switch to another rom? And currently i am using eui 5.9 21s. And also i have changed the bands to lte by *#*#4636#*#* and changing apn bearer to lte, but after some the band automatically shifts from lte to unknown.
Did you get any solution? I'm facing exactly same problem.

LTE in the UK

Hi everyone,
Does anyone have any information from an official (or very reliable/convincing) source as to which LTE bands the 10 Lite supports? I would need Band 20 at the very least. If I want to use it in the UK in English, should I wait for a "Global" version to be released?
