Security and privacy have been enhanced by updating to Android 10.
↓
There are three major changes regarding security and privacy.
↓
Updated to a new encryption method that is less likely to be cracked.
↓ You can now freely change things like fingerprints on your device.
↓
Until now, all the apps were stored in a large room, so it was easy if each app wanted to do something wrong with the apps around it.
↓
With the new method, it became difficult (not impossible) to do bad things to other apps by putting each app in a small room.
↓
With these changes, security and privacy are significantly enhanced over Android OS 9 (Pie).
↓
About Android Vulnerability
However, smartphones are always vulnerable.
↓
Especially if you use a native app to use Android, google will understand your propensity and tendency from the search results and shopping history of Google search.
↓
If you use GoogleMap, you can get location information from your home, such as where you work, where you often go on holidays, and your daily routine.
↓
From the information of the photo app, contact app, schedule app, notepad app, and Gmail app, Google can grasp information such as physical data of you and friends, tastes, faces, work relationships, personal thoughts, etc. from your Android device. Collect
↓
Furthermore, if your smartphone is made in China, you may be in a situation where you continue to give your personal information to the Chinese Communist Party, Google.
↓
This is always a state of being legally obsessed with stalker, and you can't cry secretly in the middle of the night.
↓
Graphene OS is a custom ROM created to close this security hole that probably won't be closed semi-permanently.
↓
By installing GrapheneOS, you can realize a polite and comfortable sense of distance while being close to each other.
↓
Correctly, the convenience will be greatly reduced, so it is recommended to carefully examine the contents before making a decision.
↓

Impressions of the replacement
Unfortunately, smartphones, whether they are iPhones or Androids, had a vulnerability that kept them stalking.
↓
Android + GrapheneOS has finally freed me from stalking to some extent.
↓
GrapheneOS is a custom ROM designed to eliminate native apps and code that could net stalking from a native Android 10 system.
↓
It's recommended for those who value privacy, those who are unbearably morbid minimalists with native apps eroding the screen, and those who are suffering from the damage of large corporate net stalking.
↓
It is also a good impression that the operability and system are the same as Android 10.
↓
However, since you cannot use the google play store, you have to download the stray apk file from the stray site to download the application.
↓
It's hard to say that malicious stray sites haven't put backdoors or trojans on their apk files.
↓
You've been freed from stalking big companies, but if you want to make it more convenient, you're at greater risk of being exposed to the threat of viruses.
↓
This is a trade-off, so I think you should decide which one is more important to you.
↓
There is one point to keep in mind for Chinese, Japanese and Korean users. This Graphene OS does not include Chinese, Japanese or Korean input devices.
↓
Chinese, Japanese, and Korean users must search for typing [japanese input apk] if they want to type using these languages, and install the typing app individually. not.
↓
Since the language display is included, the language display is possible. Please note Chinese, Japanese and Korean users.
↓
This is the end of the explanation of Graphene OS. Thank you for your hard work.
