For example, my latest investigation shows that it took ms just to get the filesize, then it sat idle for ms, then it downloaded a 2MB file in ms.

I would advise to use a proper download manager, instead of Google's. SomeoneSomewhere I totally agree, I switched to the fetch2 library a long time ago it's pretty fast and solid , but DownloadManager is the more standard and long term answer I could give.

As an Android user, they know basically everything about you based on your device usage.

That can easily scare some people off who are worried about their privacy and security. You do have some say in what personal data Google controls, but what if you want total control?

One of the best ways to take complete control over your device is to install a custom ROM. A typical custom ROM comes without Google's core apps Gapps , but you would typically install the separate Gapps package to get them back.

However, if you want more freedom and privacy, you would just skip the Gapps package and go with MicroG instead. You should note that many apps require Google Play Services to work correctly; otherwise, there would be no point in having them installed. MicroG injects a modified version of those core Google services required by most apps, but without all of the tracking that comes with having a Google account.

This increases your level of privacy and can even improve battery life as well. Just about all custom ROMs support signature faking by default, which is used to make the system think the real Google Play Services are installed.

It is required and necessary for this whole thing to work. You might need to double-check the place you got your custom ROM from to see if it does support signature faking in the first place for MicroG. At this point, you should already have picked out a custom ROM you plan on flashing to your device, and it should have support for signature faking.

As mentioned before, you would typically install a Gapps package after flashing a ROM to get the Google services back onto your device. However, to use MicroG, you must make sure you do not install a Gapps package at all when following this guide. If you did install Gapps by accident second nature , go ahead and flash the custom ROM again and wipe data to be safe. After you take care of that, boot into the operating system, and make sure the Google apps and services are not present, then you can move onto the next step.

In the past, to get the entire MicroG package to work, you would have been required to download multiple separate apps. There's also a newer and more convenient Magisk module that's perfect for the root users out there. You can't go wrong with either method! For all of the TWRP people out there who like to keep things as simple as possible, installing NanoDroid with MicroG baked right into it couldn't be any easier.

To get started, hit up the download link below and save the file onto your Android phone's internal storage via the "Download" folder. Once you download the file, go ahead and boot into recovery mode to the TWRP main screen. Tap "Install," browse for the location where you stored the NanoDroid file, tap it once, then swipe the slider to begin the installation.

After it finishes the install process, you can reboot your device, then you can head onto the next step below. For the root users, developer nift4 previously Hieu Van has cooked up a special Magisk module for getting the job done systemlessly without needing to rely on TWRP.
