If this phone was opened for service, replacing a battery or other parts, careful attention to reassembly can ensure against squeezing wiring or chafing. If water or other fluid entered and not opened for removal of remaining fluid, this can create short circuit conditions. Dropping onto a hard surface presents numerous issues.
