If encountered a nokia 3710 fold that does not detect any microSD memory card inserted to it, and it indicates that No memory card inserted or insert memory card on the display.
The solution below may possibly help fix this problem.
Aside from memory card corrupted problem issues which cause by a faulty or damaged microSD memory, the "memory card not detected problem" can be caused by a faulty memory card circuit components on PCB board. Some factors were caused by a dirty or corroded pin on the MicroSd card slot.
Check and ensure first that the memory card holder or slot is perfectly clean, all pins were not misaligned desoldered or already damaged.
If the MMC slot is okay, trace the memory card supply voltage, this voltage feeds from the power IC (GAZOO). Just apply a jumper wire if this supply voltage line paths is open or cut.
If the voltage line paths is okay and can read about 2.8 volts on that spots but still the problem still exists.
Reworking the GAZOO IC might only fix the nokia 3710 fold memory card not detected problem.
