I have updated my Samsung Galaxy Grand 2 to 4.4.2 and after that I'm not able to change my lock screen wallpaper. It always shows a wallpaper which is already in the device which has red background. Home screen changes every time whenever I want to change but lock screen remains the same. But if I put a live wallpaper as my home and lock screen it applies to both home and lock screen. Please suggest something how I would be able to put any pic from my gallery as lock screen. I changed the lock screen through settings also but no use.
I have a HISENSE SERO7 e2371 tablet here. I could not get the lock screen wallpaper to change at all.
Finally figured it out and thought I would post it here just in case anyone is looking for a solution.
I went into Settings → Security → Screen Lock and changed Hisense to Slide.
It seems that it was an issue with the Hisense custom lock screen they provided, so this may be same on other devices where the manufacturer has added a custom lock screen option.
just a quick search results show me that you may try power off and removing the battery some people face the same issue after update
Just change unlock effect.. There you go.. You can change lock screen wallpaper on Grand 2. Setting-device-lock screen - unlock effect. Change it. Thank you
I think it is software glitch on the Grand 2. To solve the problem, try to transfer the SIM 2 to 1. You may be able to change the lockscreen wallpaper.
