Why reset your Samsung Galaxy A9 (2018)?

Frequently asked questions
Will a hard reset delete everything on my Samsung Galaxy A9 (2018)?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung Galaxy A9 (2018) to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Samsung Galaxy A9 (2018) remove the SIM lock or carrier lock?
No. A hard or factory reset only clears data and settings — it doesn't remove a carrier/SIM lock, which is tied to the device's IMEI at the network level. You'd need to contact your carrier for an unlock.
How long does a factory reset take on the Samsung Galaxy A9 (2018)?
Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.
Will I need my Google account password after resetting the Samsung Galaxy A9 (2018)?
Yes, if Factory Reset Protection (FRP) is enabled. Android (and HarmonyOS 2.x devices with Google services) will ask for the last signed-in Google account after a reset — make sure you know that password first.
What is recovery mode on my Samsung Galaxy A9 (2018)?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Samsung Galaxy A9 (2018) won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
Can I factory reset my Samsung Galaxy A9 (2018) without the password?
Yes — resetting through recovery mode doesn't require your lock screen password, since it bypasses the login screen entirely. That said, Factory Reset Protection may still ask for your Google account credentials afterward as an anti-theft measure.
How do I reset my Samsung Galaxy A9 (2018)?
Use the Hard Reset method above if your Samsung Galaxy A9 (2018) is frozen or won't respond, or the Factory Reset method if the screen still works normally — both are covered step by step on this page.
