Some people may accidentally delete their contacts from Android. How to get those important contacts back? When you deleted contacts from Android, they were not really gone, but only marked as useless on your phone and could be overwritten by new data.
Therefore, you'd better stop using your phone after losing your contacts, to ensure a higher rate of recovery. Accidentally deleted your messages from Samsung phones, like Galaxy S3, S4, Samsung Ace, Samsung Wave? Actually, when the message is deleted, it doesn't go to the trash or the recycle bin, because there isn't a trash or a recycle bin on your Samsung as on the computer. And it's only marked as useless information and can be overwritten by new data. Therefore, the deleted message only turns to be invisible, and disappear until being overwritten.

If you stop using your device immediately after losing your data, the data still can be recovered with the aid of an android data recovery software.
