Though formatting is always the workable solution to most Android phone or tablet problems such as App flash back and inexplicable errors frequently occur on memory card, it would inevitably result in data loss and cause great inconveniences. Hence, there's every reason for you to learn to recover lost Android data after format with Android data recovery software.
Perhaps the biggest headache you'd meet is which software you should trust since there're so many free Android data recovery software available on the market. Fortunately, I've find one trustworthy based on my own experience: Tenorshare Android Data Recovery Pro.
Tips: I've also used Undelete 360 and Recuva, but neither worked. Undelete 360 took 1 minute to scan for files but came up with 0. And 10 minutes still seemed not enough for Recuva to "Deep Scan" an 8 GB SD Card.
Android Data Recovery Pro enables you to freely and quickly recover contacts, call history, text messages, photos and videos from all Android phones and tablets including the latest Samsung Note 4, MX 4, LG3, Sony Xperia E3, Samsung GALAXY Tab S, LG G Tablet 8.3, etc. And the following are the detailed steps.
