Configuration of position determination (location) – proposal:


Suggestion:

I think it would be useful to have possibility to choose by checkboxes, which networks I want to use for determination of my position (location).

A phone or another Android device is able to determine its position using GPS, Galileo, Glonass, BeiDou and Quasi-Zenith satelite navigation systems (receivers).
It is also possible to determine its position by Wi-Fi access point (but some of them can be mobile)
and by GSM (including UMTS, LTE, 5G) network (by distance from BTS).
It is possible to switch all of these sources of position information on or off at once, by one common toggle.

I believe it would be useful to have possibility to choose zero to N choices.
I quite miss it.

I think it can be very important in case that some of networks will have some error, fail, or inaccuracy,
caused by any reason (intentional, or accidental).

I have such experience, that the phone, which have receiver of 3 or 4 satelite position networks, can have shocking inaccuracy, even if in open countryside without high buildings.
I think that phones with GPS (and GSM) localisation used to be more accurate sometimes.

Possibility of choice which system to use and which one not would be useful even if in normal peace situation, when any provider does not intent to confuse people (and their devices) in another countries.
In time when provider of some navigation network is at war there is one more reason to give possibility to disable concrete satelite systems manually by user, having enabled another ones.

(In case of dual SIM it would be good to have switching on-off separately for each SIM slot (for each GSM transceiving unit).)

I have posted this proposal to Google Issue Tracker
and I have also sent it to customer support of one producer of cell phones based on Android.
(I do not know if another producers have possibly this function in their firmware; so I have contacted one producer only, since I know it has at least one model without this possibility.)
