My Samsung S21 running the latest Android (13) doesn't offer the option to disable 2G while keeping 4G/5G. The list is literally: 2G/3G/4G/5G, 2G/3G/4G, 2G/3G, 3G only, or 2G only. If you want to keep 4G and/or 5G you're SOL. Personally, I would prefer 4G/5G (as the 2G/3G fallback on my network next to useless outside the 4G/5G coverage footprint). Hopefully when Android 14 comes to the S21 it comes at least the option to disable 2G as described in the article.
- notatoad 3y agois this a carrier limitation? IIRC there used to be something about verizon requiring a 3G authentication step to connect to their 4G network
- numpad0 3y agoEarly releases of LTE just didn’t have a spec for voice call, so the phone would disconnect and reconnect in 3G when a call was happening(circuit switched fallback). Maybe that one?
- ProtoAES256 3y agoCan you change it in ##4636## though?

- Xeamek 3y agoMMI (man machine interface) codes. Some of them are dictated by telephony standards, some by carriers and some (probably most popular) by device manufacturers. Basically they let you access various features and settings
- zekica 3y agoIt is actually star pound star pound 4 6 3 6 pound star pound star. 4636 represents INFO.
- jeroenhd 3y agoYou'll need to escape the Markdown here. *#*#4636#*#*
- ProtoAES256 3y agoAhh yes, I forgot about the markdown, thanks. Too late to change though :C
- Xeamek 3y agoPretty sure those settings are dictated by carriers configs
- vel0city 3y agoI think that's a Samsung limitation. The Pixel I'm currently holding has a "Allow 2G" toggle in the settings. https://www.xda-developers.com/android-12-disable-2g-modem/ https://www.xda-developers.com/android-12-disable-2g-modem/
