4G on/off toggle

This is for the Verizon LTE version of the Samsung Galaxy Nexus.
I am tasked with writing a tiny app that will effectively disable/enable 4G capability. This can be done manually via settings > mobile network > network mode and choosing either LTE/CDMA (4g enabled) or CDMA (3g only).
I have not tried anything yet because Android development isn't my strong suit. I am looking for guidance... examples, code samples etc. I am assuming this should almost be a one-liner, but it has been my experience that with Android development nothing is as simple as it appears.
I am exploring ConnectivityManager and setNetworkPreference but I'm not sure this will do what I need.
Any help will be greatly appreciated.

I don't know if this may help you at all or not...but there is an app called ANYCUT and u can make shortcuts of an activity..in example....instead of dialing *#*#4636#*#* for the phone info and for you to switch data from 4g to 3g....u can set up a shortcut with it also for network modes..instead of going to it .but I hope it helps in some way ....maybe not what you were looking for...but a toggle widget sure would be appreciated.

having attempted the same thing, i think you'll find toggling the 3g/4g is not trivial since after 2.2 they removed the ability to modify phone state.
I created a widget to shortcut to the settings (similar to a few that are out there already) am just polishing a few preferences.

Ahhh, good to know. So in your opinion should I give up? I can go to my pm and explain that this is "essentially" not possible. Unless it *IS* "possible." What are your thoughts?

Not sure if this helps but Widgetsoid will already do this. Few of the widget functions do work (it's not fully supported on ICS) but it will toggle 4g or 3g on and off. The key is setting the Data Toggle option in its menus to 'Root Toggle'.

4G says experimental on the version downloaded from the devs website. Cant check it to enable the widget

I believe that's to toggle between 3g/4g. The option to add it as a button to the widget is greyed out so that definitely doesn't work. However you can create a button that will toggle data off, whether you're using 3g or 4g.

A friend of mine created this widget a few days ago for me. The widget works for showing if lte is on or off. upon tapping the widget it takes you directly to the mobile network settings page effectively reducing the amount of time to toggle it.
he said the only way to make it actually work would be to have the app id be the same as the system id, it would have to be done via flashable zip and not just a simple apk.

If you guys are going through that much trouble to turn data on and off you should try widgetsoid.

I'm operating off memory because I don't have my phone in front of me...
Fist, make sure you installed widgetsoid2.x!! Also, he recommends a reboot after install. This may just be to get the widgets in your widget list. And of course, you must be rooted.
I dropped a widgetsoid widget to my homescreen and went into its configuration. The button you need to include is 'Enable/disable Data' (one arrow pointing up and one down). The other key is to choose 'Root Toggle' in global preferences. When you're done setting up your widget click apply.
That did it for me. Let me know if you're still having problems and I'll try and reply with my phone in front of me next time.

i wouldn't get too excited... turning data ON/OFF and toggling between 4G/3G are separate controls, i haven't tried the data toggle yet (to see if it's a real toggle), but the Widgetsoid 4g/3g "toggle" definitely only opens the settings menu. still, Widgetsoid is so awesome that i purchased the donate version.

Google Maps location not working in power saving mode

I'm using a Tab S 8.4 LTE, having an issue using Google Maps. When Location is in power saving mode, trying to find my location in Google Maps just gives me a dialog box asking me to turn on GPS to improve location accuracy, and after I decline the blue location button simply refuses to work. Google Maps is the only app that has this problem, every single other app that needs to find location has no problem using Power Saving Mode location service to find my location, whether it's a weather app like Accuweather or a map app like Citymapper, or even the browser version of Google Maps. When I choose to turn on GPS it actually does find my location immediately, while the device is still searching for a GPS signal. I already tried clearing cache and data and reinstalling Maps. My Tab S is my only device that is having this problem. Does anyone else get this?

The thing is pal by declining the only thing it has to work off then is your WiFi and mobile data which takes longer.
For anybody who disagrees with the wifi not being usable as a location aid well it surprised me to find that when google sent those vans around taking those lovely detailed photos of your street thats not all they were after. They also logged every wireless network they went past with their location at the time so that if needed you only had to have wifi switched on and an internet connection to give a pretty accurate reading of your location...
And theyve gone even further...they dont need to send vans out to keep this list updated.., they actually use your phones ...so you become a network information gathering tool which sends back to google any wifi networks you find combined with the strengh and location you were in
Sneaky blighters
So in answer to your question either turn on gps or turn on your wifi and mobile data...or just wifi if its connected to the net.

It doesn't just take longer, it just doesn't work at all in any way, even with both WiFi and mobile data turned on. Instantly works when I activate GPS, even if I'm indoors and the device still hasn't find a GPS signal to refine the location.

Like I said everything that isn't google maps app, including the browser Google Maps, has no problems. In desperation I tried a factory reset too but that didn't work. I just wondered if its only me who is having this issue.

Thanks for the help. Sadly turning location history on didn't solve it for me for whatever reason but its good to know it's not just my device being faulty somehow.

Location Services Stopped Working

I've done nothing to modify my phone (Root, etc.). However, I have disabled packages, which apparently cannot be re-enabled without root access.
My location services were working even after I disabled my phone's bloat, but about a week ago my GPS just stopped working. I can turn on location services, but apps don't receive my location. Not a single app knows where I am.
Anyone have this problem?

How did you disable the packages and do you know exactly what you disabled? If it was by using an app then there should be a way to re-enable them.

That's using the latest version available on Play? You could uninstall the app then reinstall it plus there's always the reset of your phone. In Package Disable Pro make sure "Hide System packages" isn't on. Also check the apps permissions.

Yeah, I'm afraid it didn't work. Everytime I enable a package it re-enables itself as soon as it leaves the screen when I scroll. I don't want to have to reset my phone, but thats what its looking like...

Have you looked at disabled apps in the phone's settings? If it's also disabled there, PDP may not override it.

com.google.android.gms wakelock

Com.google.android.gms is wakelocking like a banshee and its driving me crazy. I have location history on, but always leave location off unless using it. Og pixel xl stock P. Ideas?

Well by the icon it has something to do with Google play services no ?

Mine is much worse. Google play services draining my battery. And this happens only when I'm connected to mobile data..no issues on wifi. It used to happen on Oreo and still happens on pie. I tried safe mode too. So definitely no other apps are causing it. I tried other ways like disabling location history, location, turned off double tap to wake and all other gestures, turned off adaptive brightness, turned off web and app activity in Google account settings, turned off auto sync, denied Google play services permission to modify system settings, etc. No I don't know what else is left to try. This is so annoying....

Mine all have "sms" something or other in the alarm title. I have location turned off, why is it trying to ping location? Any idea?!

I feel it's related to Google account because this is happening in safe mode too so it's definitely not a 3rd party app causing this drain. It would be great if someone could help us find a way to figure out the cause.

There's a Magisk module for adding Google play services to the list of apps that are put to sleep when not in use. I would try that.

Not for a system service like that running wild. You can use Greenify for non system applications (if not rooted), but you'd have to root in order to take care of this issue. You could always try doing the laundry list: wiping app data/cache, force stopping it, or even starting fresh and wiping the phone. However that would take longer than it would to root the device.

I have tried wiping data/cache, tried formatting many times on Oreo and pie as well. Looks like the only option is to root. Will banking apps/Google pay work on a rooted phone?

With Magisk it will, it is a very easy app to navigate , and rooting w/ Magisk only takes a few steps. Boot into TWRP via fastboot ( there are TWRP.img files , that's what you'd want here ) flash Magisk, reboot to system.

Looks like it's not just me...my friend who is using a pixel 2 xl is also having play services battery drain.

Any fix for this?

location status icon constantly showing

any ideas? no issues with my 2xl, same apps installed with my 3xl. I've checked the location settings for recent requests and haven't found anything out of the ordinary. maps, phone, etc. even tried disabling them briefly but it's still there

Yeah, seems like its doing the same thing on my 3XL... I don't remember that the first few days. The good thing is it doesn't seem to have affected my battery life.

I had the same thing on the Pixel 3 and it turned out one of my running apps was looking for location in the background. Even though you installed the same apps some of the default settings might not have carried over or have been changed.

my battery life seems ok, and like I said checking the location requests doesn't yeild anything out of the ordinary. revoking location permission doesn't seem to fix it either, so I'm not sure what's going on

Mine did it on the second day I had the phone. I toggled Location services off, and then back on again, and haven't seen it since. That was about two weeks ago.

My Pixel 3 has done the same a couple of times. Toggling Location in quick settings has made it go away. Seems an app sets it and doesn't unset it. Haven't identified which one yet.

I think you are correct. I seem to recall that I went into Better Battery Stats and looked at one of the statistics such as network use or partial wakelocks. It was then identifiable, went into the app and turned off location sharing. It never came back. This is not a function of the Pixel 3 but of some rogue app.

Not really blaming the Pixel, but I just migrated from a Galaxy S7 and never saw this with the same apps I'm using on the Pixel. Could be the Pixel, or Pie, is more informative about displaying that icon, which is probably a good thing. In any case finding the apps responsible is the key.

Did you turn off network location aka fine location? That will do it, the Google app weather feed then locks location on. Took me three months on my 2 xl to figure it out.

no, I want that active and has always kept it active. has never caused the icon to stay on all the time

If you are using the Google app beta that might be your problem I had the same issue I removed the app rebooted reinstalled the Google app non beta version all is well now

It's the Google app causing it if you have the beta version of the Google app installed. The location icon shows any time you go home from using an app. I rolled back to the stable Google app because I got tied of it. Now I no longer have the problem. Try it. Go to your Google app and turn off location for it and see if it helps. That was what caused it on mine.
