The greatest app for permanently deleting data from Android smartphones without a backup is FoneLab Android Data Recovery Software. This is a sophisticated and potent tool for recovering your phone’s deleted data. It will assist you in recovering permanently deleted vital files from a variety of scenarios, including but not limited to: water damage, broken files, factory resets, upgrades, unintentional deletions, and formatted files. You may recover a wide range of deleted items with this application, including call logs, WhatsApp messages and attachments, contacts, videos, music, documents, and much more. I would highly recommend giving this utility’s free demo a try. It may freely scan and see deleted objects in preview.
