Play Poland Roaming & LineageOS OTA Security Update

Play Poland has a complicated operation where the user is switched to a competitor's network when there is no coverage within your own country. Who knows the technical details of that arrangement with those alternative networks. Maybe the network switching is seamless and the phone does not receive info from the Orange Poland provider that it is roaming.

Roaming normally is when you are in a different country & your phone connects to a different provider that has a deal with your local provider to provide service & usually at a different rate for data & 3G.

From what I know it's the network that tells the phone that it is roaming if it is enabled in > Settings > Wireless & networks > More > Cellular networks > Data roaming.

[MENTION=2567034]slimdick[/MENTION] I edited this part: I don't understand Polish but this seems to be the page for setup: https://www.play.pl/pomoc/serwis/reczna-konfiguracja-telefonu.html which includes a link to their forum where other Play Poland users may tell you if they see a roaming notification in their status bar when using their phones within Poland: http://forumplay.pl/

"...It connects me with Orange, mobile data is disabled, because in the roaming the free package does not work" - That was my guess & it replies to your original loosing data question maybe.

I don't think that there is a problem with LineageOS reporting roaming in the status bar but it's rather related to the way Play Poland works & their technical relation with other local providers.

Play Poland may want to hide in the status bar the fact that you are connected to an other network because it shows their lack of cellular coverage in a given region. :eek:

Is that when in a different country? I don't think there is anything different between the official Lineage 14.1 for S3 i9300 & the older experimental LineageOS 14.1 for S3 version when it comes to the telephony roaming reporting part @ the present.

LineageOS OTA Security Update

FYI for those who don't update often there is a Bump security string to 2018-06-05 in the current official LineageOS for S3 i9300 2018-06-14 as seen in https://download.lineageos.org/i9300/changes/

Downloading & applying the LineageOS 2018-06-14 update via the built-in Lineage Updater was smooth as usual w/o affecting Open Gapps & Lineage su add-on (super user for root) and all is OK so far. (screenshot)

On WiFi it took about 10 minutes to download, 2 minutes to automatically being applied by the TWRP 3.2.1 OpenScript after clicking OK to Apply update and 5 minutes for the phone to automatically reboot fully in System.

I used to do this LineageOS updating manually: downloading to computer, connecting the S3 & copying the file to the phone, rebooting in TWRP recovery, wiping Dalvik cache & Cache, flashing the update & rebooting to System. :p

Afterwards using a root enabled file manager I move the LineageOS new build from the /data/lineageos_updates/ folder to the external Micro SD card in case I need it later but it can be easily deleted w/o root from the Settings > About phone > LineageOS updates panel to save space in the internal memory or you can set the Updater > Preferences > Delete updates when installed as seen in the second screenshot.

I prefer to check manually once in a while for Lineage updates with the S3 connected & WiFi enabled to avoid yet an other service running in the background & cellular data usage.
