How can I have differebt lock and home screen photos on my android?

It depends on your version of Android.

Try this:

Settings icon - Display - Wallpaper

You should see an option for Home screen and Lock screen.

Press one of them and select the picture you want.

Repeat for the other one.

To get different lock you can install GO launcher Ex and download GO locker.

To home screen photos you can have multi picture live wallaper.In this you should select some pictures and time.SO that the pictures will be automatically changed.

Hi,jennifer in your question the name of your device and android version is not mentioned.

So,to help you i can only say that::::

GO TO GALLERY THEN GO TO IMAGE SECTION WHERE THAT PARTICULAR IMAGE EXIST,,

THEN OPEN THAT IMAGE,,,AFTER OPENING YOU CAN SEE THAT THERE IS OPTION MENU ON THE TOP OF THE RIGHT WITH SYMBOL OF LINES LIKE THIS(=),,,TAP THIS ,,,,THEN YOU CAN SEE THAT VARIOUS OPTIONS POP OUT,,,WHERE YOU CAN SEE OPTION OF *SET IT* OR *SET IMAGE AS* OR *SET WALLPAPER FOR*(DEPENDING ON ANDROID VERSION),,JUST TAP THIS ,,,THEN OPTION POP OUT FOR HOME SCREEN OR LOCK SCREEN.

OR PRESS&HOLD YOUR HOME SCREEN(TAP IN CENTER OF SCREEN),,,UNTIL OPTIONS POPS OUT LIKE:::WALLPAPERS,HOME SCREEN,LOCK SCREEN ETC.

BY TAPPING LOCKSCREEN/HOME SCREEN YOU WILL BE ABLE TO SET WALLPAPERS SEPARATELY.....

THIS IS METHOD OF ALL ANDROID PHONES,,,TRY THIS OR MENTION YOUR DEVICE NEXT TIME,,,,GOOD LUCK.
