Remove the SD Card and SIM Card, and then do a Factory Reset.
If your device doesn't use full disk encryption, and you are worried about someone using advanced forensic tools to recover your data, you might want to overwrite the internal storage area with random data. You can do this by creating a file containing random data that fills up the entire free ...
This question has been bothering me quite some time. So now, finally, I decided to get to the bottom of the issue.
The Playstore has an app named permission.READ_PHONE_STATE, which requests READ_PHONE_STATE as the only permission, and does nothing else than printing out all data it can access with or without using it. I've installed that on my LG Optimus 4X, ...
tl:dr; addressing OP's question - sorry, no way AFAIK. From Android 10 onwards normal apps can't access IMEI number.
Revised answer with additional inputs from Izzy (thanks)
How do apps (Google or third party) identify you?
Apps identify a device using:
Some or all of device identifiers, mainly Android ID, GSF Android ID, build serial number, and ...
Verification by OTP uses a different API which doesn't need read SMS permission. You can read more here Perform SMS Verification on a Server

Yes, it can, but only on Android 4.3 and lower. This is used for example in Whatsapp. When you activate the app, Whatsapp sends an SMS to the number you reported, and the app intercepts it quietly and reports to the servers that it has received the SMS. This is how the account is tied to your number.
Of course, this can be used in harmful apps also. If an ...
In Windows, if you open Manage password in Chrome, then it asks for a master password (i.e. Windows Admin password) to view and manage your passwords. But that's not the case in Android. So for security purposes, Chrome for Android doesn't reveal the password.

Not exactly matching your description (using the "last known" position if not GPS available), but still a good alternative:
On two of my devices, I completely got rid of all proprietary Google services, replacing them by alternatives. In detail, I've described this in Android without Google 5: Free your Droid!¹ (update¹). In short, this is what I've done:
I don't think there is a good way to do this - the issue isn't that the private number is being hidden by your phone, it's that the phone company isn't transmitting the caller id info to you at all. So there shouldn't be any way for you to get that data working strictly from your phone.
Unless you know people who regularly block caller ID data, but don't ...

with SMS_RECEIVE permission can read but not abort an incoming SMS
Android 4.4 and above : Any app with SMS_RECEIVE permission can read

A factory reset reformats the phone's user-data partition, but it's not a "secure" wipe; it doesn't overwrite everything with zeroes. If you want to be sure everything is erased, you can encrypt the phone first (which overwrites all the data with encrypted versions of itself), then do a factory reset (which sets up a new unencrypted filesystem).
You could try this app: GPS Aids.
It tries to provide a quicker and more stable fix by providing a couple of GPS aids (GPS Aiding Data like LTO Long Term Orbits, gpsOneXTRA and AGPS), and it caches your last known GPS data.
It will run without root, but some options require root access.

Yes, a device administrator only has permissions to do what it says.
If you change the permissions of the app that the administrator is associated with, the administrators permissions will not change

HOW DELETED DATA IS RECOVERED?
Data (un)deletion strongly depends on how a storage media (HDD, SSD, eMMC etc.), filesystem (NTFS, FAT32, ext4 etc.) and OS save and delete files.
File carving / signature search / content-aware recovery identifies standard signatures values in the headers of deleted files (as file command and antivirus programs do to ...
Dan already pointed out that this is more a social problem. Talk with your parents, express how you feel about this. The feeling of being constantly monitored is sure not very pleasant.
That said, the only way to make it hard for someone to monitor the location with the help of your Android phone is by ensuring that you have a clean initial setup and a ...
How about Chainfire's tool Pry-Fi which was announced over at XDA?
It works great and it is available via the official Google play-store at:
Here’s a screenshot showing the tool in action…
XPrivacy is not a stand-alone application. It's a module of the Xposed framework, and thus utilizes the latter to achieve its goals. So if the Xprivacy dev "reports in", he might just say: "Waiting for the Xposed team to show up"...
Oh, if you don't wanna wait: head straight to the Xposed thread at XDA for all the details. The intro over there states:
In contrast to the comment from Zlatty, I was very pleased to learn that the pro version of xprivacy can do just that. I use it to allow whatsapp selective access to contact book entries only if I know that the person in question is already registered with whatsapp.
Blocking contacts by default:
Allowing partial access:
There are low(er)-level commands that can be used in a shell to encrypt your user data partition. Disclaimer/Warning: the following instructions will wipe your data, ensure that you make a backup if needed.
Following these steps, you should be able to wipe your data partition and have it encrypted afterwards (similar to a factory reset):

I would use firefox. It has an option to clear on exit. You do have to go to the menu (which you can access by tapping the menu icon) and hit quit every time, but seeming as there is no way I know of in chrome, It's better than nothing. Firefox does take some getting used to though, so switch with caution.
Google Partner Setup is an app that helps you run applications in conjunction with Google products. For example, with this application's help, you can use the calendar from your device with a ToDo app that you've just installed.
As for the intrusive permissions, you are right. I don't understand why it needs all those permissions, if all it does is ...
Cases that doesn't affect your current permissions:
Updating app from play store.(also maybe the same for apk install too)
When you disable/enable any app.
When you clear only app cache.
When you force stop and restart.
During uninstall updates of an app. (This action is performed automatically when you disable that app).
Cases that may reset your current ...

No, apps cannot be installed on SIM. What you describe are rather SIM services. AFAIK you can use those with the "SIM Toolkit" app only (which is where you also should find your <operator-name-here>, and where you should be able to see what's installed there).
As long as you did not actively subscribe to any of those services, they should simply stay ...

Your #1 is simply an introductionary phrasing. With Android 1.6 and before, this permission was ...
