I don't know how these files got in my photos I get photos saved in a folder named files, I don't know the people in the pictures . there not photos I took ! How could they have gotten into my phone? and details show /storage/emulated/0/Android/data/com.littleengine.wordpal/files/ .......plz help.
This seems to be the Data asociated to an app called World Wars maybe some other (you can google "com.littleengine.wordpal" to know what aplication is, that is the package name), it's possible those photos are there because are saved data from gameplays or other players avatars, in this case there is not too much to worry about, except for the space of course. If you don't trust the source of the application i recommento to uninstall it, but if you installed it from the Play Store there are almost sure not problem at all.
Anyway, if there is not such application like World Wars or any other, find that folder with the pics and delete it, there'll no be problem, if the folder appears again, consider to install an antivirus or something
