How do I fix this when the only thing showing up is a green android symbol on the reset screen and nothing else. I don't even get the option to reset on this screen.

Three Reasons Why Screen Lock is Gone
1. Screen Lock has been deactivated (Instructions how to activate are at bottom.)
2. Android Screen Security File may have been deleted, and screen lock option is no longer on your devise.(A Factory Reset will restore original Android files)
3. Malfunction Somewhere in Samsung Phone. (A Factory Reset might work, but not guaranteed)
(How to Factory Reset phone at bottom.)

How to ativate Screen Lock and Security settings

1. Press the apps icon, it usually at the bottom of screen.
2. Find Settings and press that button to open settings menu.
4. Scroll down the menu to Lock Screen and Security, press that to open options menu.
5. The first option at top is Screen Lock Type.Press and Open.
6. You will have 3 lock types to choose from. Swipe Lock, Passcode Lock, Password Lock
(advise, do not forget password, only a hard phone reset, or an apk lockout file will get you back in)

If activating screen lock through settings did not work, or if option is not available, you can try to reset phone to the way it was when you bought it.

There is a couple things you should know.
1. contacts, photos, videos, downloaded apps, games, and everything not on the phone when it was first bought, or when you first got the phone will be erased.
2. You can back up contacts, photos, videos, in settings menu, scroll down to Backup and Reset. Or save to an sd card, and remove sd card before applying reset option
3. If you have an account (google or android email) associated with your phone, you will need email address, ([email protected]) and password to get back in phone after phone resets and turns on.) Dont remember password, Please create a new password now before continuing to reset to manufacture settings.

Reset Phone to Manufacture Settings
1. Remove SD Card, or its saved files will be erased.
2. Open apps, Open Settings Menu, Scroll Down to Backup and Reset.
3. Scroll down to bottom of page to Factory Data Reset.
4. Follow instructions to reset phone.

When your phone comes back on, Swipe Screen Unlock should be active at phone turn on, if screen lock is not showing try again to turn on in security settings.
If still does not work,
I am sorry, Your phone has permanantly malfunctioned. You can try your phone store, or a phone repair shop.

Many people say to push and hold down the Volume(+) and Power button at the same time. Push and hold for as long as twenty seconds until you see a green android with green text.

But, on some devices and some Android O/S versions it takes pushing and holding the Volume(-) and Power button and holding them both down for twenty seconds or so or until you see the green Android and text screen. This will show the Wipe Data/Factory reset option. Select this option by scrolling using the Volume(+) button and engage using the power button. Some devices give you a second screen with a list of *no no no no no* and one line of Factory Reset. Again, scroll to the Reset option using the Volume(+) option and select it using the power button.

If the above doesn't work, either your battery is dead or your device is dead.

How did you reset?

if all you did was create a screen display lock samsung's typically will let you attempt to enter up to 10 times before doing a master reset since you obviously have nothing on the phone to begin with just keep entering the wrong unlock code until it prompts you for the reset easy fix

Try a back-up & reset option, if you can select its settings.

Sounds like its borked.
Have you pressed the reset button on the back - pinhole - press it with a pin its a long shot.

The real fix is to go into recovery mode using the power button volume up combo. Then select the restore tablet option.

If none of that works you will have to sideload or reinstall using an sdcard a replacement OS - Try cyanogenmod - your tablet will have to be rooted and have the cm bootloader installed however - tablets are not easy things to repair when the software goes belly up.

This works with devices having physical home button

1. Press the power button and the home button together for a while, long enough until the screen appears with Android bot and a progress bar which shows that it's formatting the internal memory. With NO physical HOME button:-


2. In case your device does not have a physical home button, press the power button and both the volume keys together for few seconds.


3. Press gently the "reset pin-hole" present generally on a side of Tablet. Use a clip-pin or similarly fine thing to gently push inside to reset your device to factory settings.

Note: I Use My Tablet SUNBERRY, and reset my Tablet
Turn Off your Tablet and then
Press Power + Volume Down (Press up Factory menu Show)

If you use Android 2.2 (Froyo)
Press Wipe data / Factory Reset -> Yes, Delete ALL user data -> if Finish press Reboot Now
