Putting PIN/Password on your Galaxy S4 is surely a good way to secure your personal data on the phone. But what if you forget the PIN/Password ? What can you actually do ?
i. Perform a hard reset
To hard reset a Galaxy S4 :
- Power off your Galaxy S4.
- Press and hold the Volume Up + Home + Power buttons at the same time.
- Release all buttons as soon as you see the Samsung Galaxy S4 logo.
- In the Android system recovery mode, use the volume rocker to highlight wipe data/factory reset, and then press the Power button to select.
- Select Yes — delete all user data.
- Next, select reboot system now.
ii. Unlock Galaxy S4 via findmymobile.com
If you’ve setup your Galaxy S4 to use Find My Mobile, then you’re in luck. The Unlock My Screen feature at findmymobile.com can help you to unlock the mobile screen remotely. Obviously, your phone has to be connected to the Internet for this to work.
Here’s how :
- Using your desktop browser, log into your Find My Mobile account.
- Ensure your Galaxy S4 status is online.
- Select Unlock my screen and then click Unlock.
The methods that don’t work for me
You probably read somewhere or have been told by a friend that you’ll get a Google login prompt when you exceed certain times of wrong attempts. Unfortunately, this is only applicable to Pattern lock. I’ve tried more than 200 wrong attempts for both PIN and Password, yet I wasn’t being prompted to login to my Google account.
Besides the 2 suggestions above, I’ve also tried some of the methods that I found at xda-developers forum, which said to reset the Pattern/PIN/Password lock without compromising the data on your phone.
Unfortunately, they didn’t work for my Galaxy S4 which isn’t rooted with stock recovery. With the stock recovery, I got the “E signature verification failed” error whenever I tried to flash a .zip that isn’t signed by Samsung.
But if your Galaxy S4 has a different setup such as custom recovery, and would like to give these methods a try, hit the links below to get to the forum threads for the instructions. Having said that, I don’t hold any responsibility of what happens to your phone due to executing these methods :

- [NO ROOT] [NO USB DEBUGGING] Unlock Your Android.
Note: The steps here were written for Android 4.3 on a Samsung Galaxy S4 (GT-I9500). If you’re having a different model of Galaxy S4 or other version of Android, there’s a possibility that the steps and screenshots will be different.
