REPRODUCIBILITY: 2G always, 4G usually
OS VERSION: 4.5.0.24
HARDWARE: Sony Xperia 10 III
UI LANGUAGE: Finnisn, En-US, E-UK ← tried ones, for screenshots
REGRESSION: not at least for 4G, worked w/ same version 2023-11 (2G untried for a while)
DESCRIPTION:
After booting device, or bringing mobile data back from flight mode, getting mobile connection
up usually does not work out of the box – have to manually retry connections 1-n times.
That is the usual case. sometimes it comes up w/o any manual intervention – sometimes even
almost immediately, sometimes it takes a minute or so…
But that ie 4G only – cannot get 2G to work at all – and most probably that is also reason
“4G Calling (beta)” has to be enabled, otherwise voice calls don’t work (surprisingly SMS message
telling missed call got through)
When I put the same SIM to my Xperia X, (with 4.4.0.64), both 4G and 2G worked – and calling
when 2G only worked.
I don’t know if that is a coincidence, but FI Elisa dropped 3G in my area around November-December
2023 – tried to find exact time, closer to that there was article dated 2023-12-19 telling 3G has shut
down and what one should do…
PRECONDITIONS:
STEPS TO REPRODUCE:
- reboot device
- expect 4G to come up automatically without too much delay
EXPECTED RESULT:
4G mobile date working – and can do phone calls w/o 4G calling enabled !
ACTUAL RESULT:
4G may be denied – and after manual connection retries got 4G connection but without
“4G calling” phone calls don’t work
^^ I am experiencing this in Elisa network in southern Finland. ^^
MODIFICATIONS:
Patchmanager installed, but 0 patches enabled (could not figure out how to easily uninstall patchmanager)
Situations installed but not active (I used situations to put phone in flight mode over night to
make battery drain smaller – for some reason situations could not consistenly do that…))
ADDITIONAL INFORMATION:
^^ When manual attempt to activate Fi elisa failed ^^
^^ When automatic network selection was ‘Denied’ ^^
^^ When attempt to “2G only” just fails ^^
