Why is A-GPS dissabled by default and how to enable?

Does anybody know the reason why the assisted gps is disabled by default?? And how can it be enable. When I enable with advanced configuration it is not working.
My previous phone was a nokia e71, and there was the a-gps working perfect. I used sygic McGuider, and there was an option to use a-gps. When that option was checked you got a fixed in the middle of your house. That worked perfect. You got immediately a fix, almost instantanious.
Why do you think it is disabled?
On my TP2 I go to 'All Programs > Quick GPS' and it tells me when it last downloaded info, how long it is valid for and I can configure settings under Menu.
Quick gps is something else than assisted gps. Assisted gps uses network triangulation to support the gps position. If there are some obstacles that block some of the gps signals, and the network coverage is still okay then your signal is still okay with assisted gps.
I alse read somewhere that some costs are charged when you use a-gps, but I have never notioned that with my nokia e71. Even in a foreign country no costs were charged for using a-gps.

you can use the rhodium settings tool
it is "must to have". A.

rhodium gps location service settings. "ON and 911 only"

Is it advisable to leave the location service to "ON?" As opposed to 911 only like it comes default. I use google maps and I need to set the location service to on. But I usually turn it off to "911 only" after I use google maps. What happens to the battery usage if I just leave it set to "ON?" does it drain more juice? Does it matter?

WP7 - GPS/Location based services

Am currently using an HTC Trophy and location based services are not working. Maps won't locate me - just perpetually displays "Searching ..." - and no other app can make use of GPS.
The available settings aren't especially granular in WP7 and I don't see any options besides having GPS ON or OFF. Toggling this setting has no effect.
Any ideas?!
Thanks!
UPDATE: It's the o2 SIM. Swapped out SIM with Vodafone and Orange SIMs and GPS works both on those two networks. I don't understand as the same o2 SIM does GPS just fine in an HD2 and an HD Mini.

The only time I've been unable to get a fix is when I'm not using a SIM card. So it could be that you're required to have a working data connection as well?
Yeah, that's one thing you might think. But data connection is fine. GPS doesn't work when there's a 3G data or Wi-fi connection present either ... which makes me think it might be hardware ...

Bad idle power consumption

I am using my new G7 Play with a Mint Mobile SIM (T-Mobile MVNO). I am seeing much worse battery performance than my G4 Play on T-Mobile prepaid SIM, even though its battery is several years old now. I tested the Mint SIM for half a day in the old phone, before I punched it down from micro to nano SIM size. I didn't notice any significantly different battery consumption during that time, but I didn't try to carefully test for an entire discharge cycle.
I have tried to configure them the same way, with the same basic apps and battery optimization settings. For reference, the G4 Play can last 5+ days with my light usage patterns. The G7 Play seems like it cannot even last for 1.5 days. The battery ran down over 25% overnight. In the same time period, my G4 Play only showed a 2% drop.
This is with WiFi on and in range for most of the hours in the day (at work or at home). Signed into GMail, Hangouts, and Slack. Location toggled off. Bluetooth toggled off. And OSMAnd+ installed from f-droid. One difference is that I am still using the default Moto launcher on the G7 Play. I replaced it with Nova Launcher on the G4 Play in order to get rid of the annoying Google search/assistant widget that was not removable in the Nougat update. Both have Moto Display and Moto Actions active, but all the gesture/camera actions are turned off. It just has the notification peeking and active display when you bump or pick up the locked phone.
I have disabled Google Music, Movies, News, and Drive to try to match the config on the G4 Play. I also am not logged in with Chrome nor Photos but those apps are not disabled. I am still searching the Android 9 settings menus, but I don't see any more things I can adjust for efficiency. The battery usage details does not seem to tell me why it is going down so fast.
I am not sure what else to try, except to blindly experiment with disabling other built-in apps/services. There seem to be many more in the G7 Play than on the G4 Play, but I don't want to accidentally cripple the phone. Another possible difference is the G7 Play is using the 5 GHz WiFi channels instead of only the 2 GHz channels. But would that explain such a difference in power draw?
Same problem here, single sim G7 play on t mobile. Tried running in safe mode for a few hours and the drain is the same. The issue seems to be running wifi and cellular radio at the same time. Wifi signal is strong, on 5 GHz. Running only on cellular reduces the drain significantly, even with my crappy -112 dbm signal. I am guessing this is some sort of bug - on a related note, if I turn on airplane mode, and then turn on wifi, the cellular radio also turns on, and cannot be turned off via *#*#4636#*#* diagnostics screen.
Current build is PPY29.105-36
Strange. I put my phone in airplane mode and then turned WiFi back on. It indicated that cellular data was off and showed no phone network status. I then turned on WiFi calling and it showed that I was on T-Mobile WiFi Calling in the lock screen status. I left it idle like this for 20 hours and the battery discharged from 100% to 93%. Today, I will try the opposite, turning off airplane mode and WiFi and using just the cellular network.
Before this test, I did play store updates, rebooted, and then fully charged the phone. There were updates to Phone and Google apps right before I rebooted. My Phone app is at version 31.0.241960258 and my Google app is at version 9.51.10.21.arm. My phone is on US Retail channel and build PPY29.105-36.
Did your cellular radio stay off the whole time? Mine will toggle back on right before my eyes. My google app is at version 9.51.8.21.arm, phone app is the same as yours.
It stays off. I'm only looking at the toggles in the pull-down status menu at the top of the phone screen. I also have bluetooth and location toggled off. Maybe you should try changing some of the location/background scanning options? I turned off those sorts of things when I first got the phone.
Yesterday, I rebooted, recharged, and tested the phone for about 8 hours w/o WiFi, but with phone and data service on. It used a lot more power than WiFi-only from the previous day. It was projecting about 2 days left when I interrupted the test.
Then, I toggled off cellular data service. For the next 9 hours, the power consumption graph flattened out a bit. It's down to 85% now bit it is projecting 3 days left instead of 2.
Ok, figured out the cellular radio turning back on, it was having wifi calling enabled, which doesn't seem to make sense, but I digress.
So you turned on wifi calling, and the power draw was still low? Can you check your cellular radio status with the wifi radio and wifi calling on with the *#*#4636#*#* diagnostics screen?
If I remember, I rebooted with wifi calling off, put it into airplane mode, turned wifi back on, then thought to enable wifi calling. It definitely did not show the cell antenna signal icon in status, and showed "T-Mobile WiFi Calling" in the lock screen. I tested it by calling the number from another phone, and it did ring.
Today, I have continued using the phone with cell modem on for calls and wifi on for internet (but cellular data toggled off and wifi calling still disabled since before last reboot). It is now down to 79% power after 25 hours of operation and predicting 4 more days at this rate. This is more like I expected originally, and not so far off from my old G4 Play.
I am pretty confused by the terrible behavior in the beginning. It may have something to do with booting up with WiFi calling enabled. Or it might be some other strange state that cleared after a few reboots?
If I remember, I'll try to put it back in the wifi-only mode next time I am back on my home network to check that status screen you mentioned. But, I am nearly sure it is going to indicate cellular modem OFF and wifi ON using 5 GHz band.
The phone info screen behind that dial code shows this regardless of whether I am in airplane mode or not: Voice Service: In Service; Mobile radio power: on; VoLTE Provisioned: on; Video Calling Provisioned: on; Wifi Calling Provisioned: on. Because of the differences in other fields and in power usage, I don't believe the indicator about radio power means anything here. The Settings->Phone Info->SIM status screen says "Mobile network state: Disconnected" and "Service status: Voice In Service/Data In Service" when I am in airplane mode w/ wifi calling active.
From the 4636 code phone info screen, these fields change:
- Airplane mode w/ wifi calling active: Signal Strength: -1 dBm 99 asu; Data Service: Disconnected; Voice Network Type: Unknown; Data Network Type: IWLAN.
- Cell on w/ wifi calling active: Signal Strength: -112 dBm 28 asu; Data Service: Disconnected; Voice Network Type: LTE; Data Network Type: IWLAN.
- Cell on w/ wifi calling disabled but wifi on: Signal Strength: -113 dBm 27 asu; Data Service: Disconnected; Voice Network Type: LTE; Data Network Type: LTE.
- Cell on w/ data on and wifi off: Signal Strengh: -110 dBm 24 asu; Data Service: Connected; Voice Network Type: LTE; Data Network Type: LTE.
And the IMS status screen further down under the three-dot menu changes:
- Airplane mode w/ wifi calling active: Voice over LTE: Unavailable; Voice over WiFi: Available.
- Cell on w/ wifi calling active: same as previous.
- Cell on w/ wifi calling disabled but wifi on: Voice over LTE: Available; Voice over WiFi: Unavailable.
- Cell on w/ data on and wifi off: same as previous.
It's only in the 4th config that I actually see "LTE" on the network signal icon in the phone status bar on the home screen.
I should also note that I set the wifi calling settings to wifi preferred/wifi for both choices.
Thanks for all of the troubleshooting info.
I guess this shoots down my simply both radios on theory. You still get bad drain when wifi and cell data are both on?
I gave it about 18 hours to find out. But no, it now seems to have little effect to turn on cell data and wifi together. The phone is continuing to have a pretty good standby power drain with WiFi, cell voice, and cell data turned on.
I'm down to 52% battery and it has been 3 days it was last charged. The power graph shows nearly the same slope over the last couple days whether I turned cell functions on or off. Where there were dips, I think it may be partly that I took the phone away from WiFi, so it started actually using LTE data, and also that I had the screen on some around those times to look at settings and respond to some texts etc.
I'll keep playing with it for a while, but I am also running out of ideas. What's frustrating is that the battery consumption info listed just cellular standby as the originall high power use, not some other app or OS function that would be easier to explain as software-caused.
Just about the only settings I have left to re-test are WiFi calling (with cell modem on), Bluetooth, and Location. I suspect that the location was on constantly in the first day because I wasn't used to the Pie status bar. In my G4P running Nougat, the location icon would be visible in the status bar whenever it is on. But on the G7P, it doesn't seem to indicate anything unless you open the drawer and look at its toggle state.
I worked my way all the way back to having everything toggled on... cell voice, cell data, wifi, wifi calling, and location. It dropped from 100% to 96% in 12 hours overnight, and estimates 10 days remaining. This is far different than the 20-25% drop I saw in the first days.
The only explanations I can think of for this whole experience so far:
1. The power use was due to application behaviour, but the usage details screens were not assigning blame correctly.
2. The battery charge estimates themselves were wildly incorrect in the first days.
3. The phone is configured to waste power out of the box, and has to "learn" to conserve power when idle.
So, the phone seems to do quite well now. I just hope it doesn't decide to switch back to its high consumption mode when I am depending on its battery to endure like it is right now...

We know that would be an issue for sure, but the question is whether that's the only issue. I'm hoping it is.

OnePlus 7T on Google Fi

Has anyone activated a OP 7T on Google Fi recently? If so, does it work well and does WiFI calling work?
I have activated my OnePlus 7T on Google Fi and have been using it for about 2 or 3 months now. I'm not sure about the WiFi calling, I don't see an option for it in the Google Fi app, and I don't see an option for it in System Settings anywhere. I can tell you that you can't install Google's Phone app. I don't know why, it shows up in my Play Store Library, but I don't have the option to install it. Service is still good. Sometimes calls do take time to actually start dialing and there are a few locations in my area between cities where my service will drop but the radius that I lose service in is rather small. I didn't have the service dropping issues with my Pixel on Google Fi.

I switch back and forth between my Pixel 4 XL and My OnePlus 7T, and I also use Googe Fi. If you're rooted, you can download the google framework magisk module. I then downloaded the google phone app from apkmirror, and set it as default phone app. I also have the WiFi Calling option in the Google Fi settings. WiFi calling is funny like that with Google Fi though. for me, the only time that I actually know that I'm on a WiFi call is when I see the WiFi icon on the connected call screen of the phone app. Hope this helps.
Yep, not google fi here, but using the google phone app. Install the google dialer framework magisk module. Then you should be able to get google phone from the play store. Make sure you go to google phone's app info and allow "display over other apps" or else the chat bubble (whatever it's actually called) won't work. I have it set as the phone app, and the oneplus one disabled.
The oneplus dialer is better suited for dual sim calling though :\
So I've got a OnePlus 7T and wifi calling had been great for several months. I just noticed today that it wasn't working, and the option is suddenly gone from my Fi app options. Has anyone else experienced this?
That said, if you need wifi calling I may hold off on switching until someone else can verify that there's is ok.
I am using it. Activated few days ago on tmo version (HD1907). Prior to that it was converted to international fw 10.0.16.HD65AA.
Everything seems to work except:
1) I have option to enable Wi-Fi calling in Google FI app, it is enabled. If I turn phone into the plane mode and enable Wi-Fi it doesn't allow me to call saying I have to disable airplane mode. This used to work on Pixel. So I cannot tell it VoWiFi works or not, maybe yes maybe not, you will never tell unless check your billing and/or be in an area where you only have Wi-Fi and maybe roaming. I wasn't.
2) I am unable to switch network to Sprint, even though it shall be formally merged with TMO by now. Signal Spy just cannot do it. That said, it used to do it on Pixel couple years ago, but stopped working even on Pixel. So I am uncertain if that is a body or merger issue. Yet have to be in an area where only Sprint or US Cellular towers are present, but this will hardly happen.
3) FI specific google VPN does not work (this is for a good in my book).
Visual voicemail works with OOS phone app.
I can install google dealer without Magisk module, so that module is not needed on this FW. I don't see any benefits to use it though, except if I would like to use Google's call screening and spam protection. I am using a 3rd party dealer anyway with its own features like that pre-existed Google's implementation. I.e. if that is an issue, that issue can be solved by a 3rd party SW, you are not bound to Google here. But you can install their dealer on global FW if you so want.
Other than that everything seems to work. I'd like to see what happens in roaming but I don't expect problems there. It would be a very strange idea to prohibit roaming based on the IMEI. Anyhow, there is no way to check during the times of closed borders.
I didn't install a second SIM yet though.

Update: today I was in the area without network but with Wi-Fi. Wi-Fi calling with FI works. I was able to make and receive calls via phone app. App was showing it is calling via Wi-Fi. So that is purely artificial SW limitation that I cannot make calls from Airplane mode with Wi-Fi enabled, when in such situation it works.
I've been using my 7t on Google Fi for about a year now. I am using stock software and stock apps for voice. I installed google messenger to resolve some chat issues (from play store). Wifi calling works as it should with stock dialer as well as mms/sms.
The only issue I have had is... the phone will not automatically switch to the strongest provider. In my area, the strongest provider is t-mobile, therefor I essentially have a t-mobile data plan through Google Fi.
Typically I find that wifi calling increases the time from when you finished dialing to the instance of the phone actually ringing. Without wifi calling, the timing is spot on.
zero complaints.
