Product(s) Affected:

  • BlackBerry 7 OS and earlier
Jump to: Environment | Overview
  • BlackBerry 7 and earlier

The following information is intended for retail support representatives who are assisting customers with troubleshooting.

BlackBerry smartphones, batteries, or travel chargers might be damaged if:

  • Exposed to rain or water
  • Placed near a bathtub or a sink, in a wet basement, or near a swimming pool
  • Liquid is spilled on them
  • Used with wet hands

Perform a visual inspection of the BlackBerry smartphone and battery to look for obvious signs of potential liquid damage. Ask the customer if they use a holster. If they do not, suggest they use a holster to protect their BlackBerry smartphones from potential liquid damage.

Potential liquid damage might be indicated by the following:

  • Active liquid damage indicator (LDI)
  • Green or white corrosion
  • A foggy screen
  • Sticky residue behind the battery

Liquid damage indicator

The liquid damage indicator (LDI) is a small tab inside the battery compartment. All BlackBerry smartphones and batteries have at least one LDI, which indicates superficial potential liquid damage to the BlackBerry smartphone or battery.

An inactive LDI appears solid white on a BlackBerry smartphone. On a BlackBerry battery, the inactive LDI may be solid white, white with a distinct red stripe, or white with distinct red XXXs. An active LDI appears solid red, indicating liquid contact. An active LDI with a pattern (red stripe or red XXXs) appears fuzzy, indicating liquid contact.

Locate and inspect the LDI. The location of the LDI can vary depending on the BlackBerry smartphone or battery. The LDI in a BlackBerry smartphone is often located in the battery compartment near the battery connectors. The LDI on a BlackBerry battery is often located near the battery terminals.
Liquid can enter a BlackBerry smartphone through openings in the keypad, the USB port, or the headset jack and cause damage to the circuit board, which may be beyond economical repair (BER). You cannot determine BER solely by looking at the LDI. Only authorized repair personnel can confirm BER when they disassemble and inspect the BlackBerry smartphone.
