Internal Phone Memory and Internal Storage Memory are two storage locations in Android devices. Internal Phone Memory is where installations files and other access restricted files are located. Internal Storage Memory is where user defined data is stored (e.g. Photos, Music, etc.).
Internal Phone Memory is locked by the Android device and hence recovering data from that location is not possible.
However, recovering deleted or lost data from Android phone’s Internal Storage Memory is possible using Remo Recover for Android software.
