We received this phone last week for water damage data recovery. First, the repair was attempted, the phone was disassembled and carefully examined under the microscope. There were few bad spots but it looked like it can be repaired.
The password you use on your Samsung Galaxy may not really stop Law Enforcement or forensic investigators from getting into your phone.
We have been doing this for a very long time using UFED and XRY.
Salt water damaged iPhone 6
Extremely corroded, especially when viewed under the microscope. Phone required: ultrasonic cleaning, board level repair to relieve any shorts and replacing few components, screen connector, and various other parts needed replacement as well.
The iPhone came back o life and data was recovered.
