I have tried to access the voice command on the Talkback menu. I have tried to use adb/fastboot. All o no avail Outlast 5g

If I am home, I am only using Wifi with 5G OFF. If I am out somewhere, work, etc. I use 5G with Wifi OFF. **The question: can I enable Wifi+5G always ON?** Thinking of security issues like: - if someone can break in to my phone via the internet/5G network, it can see my internal network (since Wifi is ON) - if Wifi is always enabled while I am outside home, can it be used maliciously? eg.: forcing my phone to connect to a fake wifi network?

I don't understand how I can be connected to 5G NSA while 5G NSA is unavailable. I'm using a Pixel Fold. (The MNC and MCC values are null, I'm not roaming, the signal is often so powerful that the dBm reading is positive (not negative as in this screenshot), and I believe this is is related to some kind of cell-site simulator attack that allows control over the 4G channel. The screen also flashes briefly every time the phone connects to 5G in the Android 16 beta.)

I have a fully-patched Pixel Fold with the latest version of Android. If I boot into airplane mode with no SIM cards installed while the “NR only” option is enabled, as soon as I disable airplane mode, the phone immediately connects to a GSM (2G) network, opening my phone up to 2G attacks despite having no SIM card. My expectation is that these connections would be blocked. I also see that the phone occasionally makes UMTS and WCDMA (both 3G) connections in this mode as well, even though 3G is supposedly defunct in the United States. My expectation is that these connections would also be blocked. If I then enable a network (i.e., Cricket or Visible) that seems to only support 5G in the form of 5G Non-Standalone (NSA) (4G+) (again, with “NR only” enabled), the phone proceeds to connect me to LTE, sometimes simultaneously with an NR network (with null MCC/MNC values and a TAC value of 0). My expectation would be for the phone to report no service. So not only is “NR only” not NR only (it allows 2G, 3G, and 4G), but if I enable airplane mode, both \*#\*#4636#\*#\* and the CellMapper app continue to report that my phone is always connected to various cells over 2G, 3G, 4G, and 5G, the latter two with a SIM cards installed and the former two without SIM cards installed. Is “NR only” just “prefer 5G, otherwise connect to anything”? Does “NR only” include 5G NSA, which necessitates allowing LTE (making the option identical to “NR/LTE”)? Shouldn’t airplane mode entirely disable the mobile radio? It seems if “NR only” is not literally “NR only”, then there’s no defense against the attacks described at https://www.mdpi.com/2624-800X/4/1/2 (which leverage 2G, 4G, and 4G+ (AKA 5G NSA)).

I have a Samsung device. My service, which is T-Mobile, keeps switching between 5G UC and regular 5G. Any information on this would be muchly appreciated

I am aware about the different apps for checking 5G connection status on Android, the most useful of which I see CellMapper which says a lot of useful info about the current 5G connection. The one piece I am still missing is the deployment type of the 5G on the cell tower I am connected to. What I mean by deployment type is either SA (Standalone 5G) or NSA (non-standalone). Briefly speaking, it is the way 5G connection is established on the cellular infrastructure, either it uses the legacy 4G equipment (NSA) or new 5G equipment built from scratch (SA). I wasn't able to find that info in CellMapper, nor in the ***#0011#** service menu Is there any way to check this info? I am asking specifically for Samsung Galaxy but appreciate any Android-wide answer. P.S. I have Samsung Galaxy A35 and I'm on Metro PCS carrier.
