Galaxy Tab wallpaper help?

[R.Paul]

Hi guys tanong ko lang baka may nakakaalam, whenever I try to change my home screen wallpaper to a photo I took or downloaded nasstuck sya sa ganito



And hindi na sya magpalit.

Pero kapag default (built in);wallpaper naman ang pinapalit ko ok lang. Bakit kaya?

Baka naman masyadong malaki ung photo na dinownload mo.
