Most of our lives are stored in Android memory, both personal and work-related information. Some people don't like losing access to it. When my phone accidentally fell into the water, it shocked me. There was no way to recover the data on my own. Someone shared this link with me
RAID Data Recovery - SALVAGEDATA Recovery and I contacted SalvageData. They told me that due to encryption in Android, it was impossible to recover data from the eMMC. Their representative was cautious and told me they would do their best. Now, having learned from bitter experience, I make backups.
