How to Repair a Jailbroken Android Phone?
It can be stressful and difficult when someone controls your phone. If you suspect someone has hacked your Android device, don’t worry – figuring out a hacker whose entry point isn’t as hard as you might think. We’ll show you the common signs that you’ve been hacked or have malware, help you fix your jailbroken device, and improve Android’s security to prevent future hacks.

Popups and performance issues.
If your device is slow and restarting doesn’t help, a hacker may have installed malware on your phone. You may also see a lot of pop-ups, including ads and payment requests, and poor battery performance.
Apps you don’t have installed.
If you see strange apps in the app drawer or home screen, they may have been installed by someone who has access to your phone. But since apps installed by hackers can be more stealthy than your other apps, it’s a good idea to check out the Apps section of the Settings app.
Unrecognized text messages and emails.
If a hacker has access to your phone, he can use it to send messages to other people, including your contacts. Check your unsent messages in text conversations and in your email application’s Sent Items folder.
It’s also possible that someone is spoofing your phone number or email address, which means they can’t access your phone.
A sudden increase in data usage.
If you suddenly use your data plan more than usual, malware on your phone could be using the Internet without your knowledge. To check your data usage, open Settings and tap Data usage. Be especially careful if most of your data is being used by apps you don’t know about.
Of course, this only applies if you haven’t changed your surfing habits recently. If you suddenly watch more videos or download more media through the messaging app, the increase in data usage may be justified.
Remove the hack.
Consider resetting your device.
One way to get rid of hackers is to reset your phone to factory settings when backing up your device data or syncing it with your Google account.
Remember, resetting your device will delete all data on your device. However, as long as your photos, videos, contacts, and personal info are synced to your Google Account, they’ll sync to your device when you sign in again.
After resetting your phone, if hackers gain access to your account, change your Google Account password. You can do this in the Settings app. To do this, go to Google > Google Account Management > Security > “Sign in to Google” > Password to do this on your device. [1]
Reboot in safe mode.
If you want to remove hackers and malware without wiping and restarting your device, first enter Safe Mode:
Press and hold the power button on your device.
When the power options appear, press and hold to power off.
Click Restart in Safe Mode when prompted. [2]
If that doesn’t work, try turning off your device. Then press and hold the power button until your device turns on again, then press and hold the volume down key until the screen says “safe mode.” [3]
These steps are for Samsung devices only. Please visit the manufacturer’s website for instructions on how to boot into Safe Mode on your device.
Remove admin and application access.
Hackers often install applications, including cryptominers, keyloggers, and spying tools, on targeted Android devices with administrative privileges. Before uninstalling the app, you can check and disable the Device Manager app:
Open Settings.
If you have a search function in the Settings menu, search for “Administrator” and tap “Device Manager Application” or “Device Manager”. [4]
If that doesn’t work, go to Security > Advanced > Device Manager app or Lock screen and security > Additional security settings > Device administrator.
Some admin apps are installed by the manufacturer (or at your workplace) and should work, so disable only those
