  5. Mainboard Damage
    Another possibility is mainboard damage.

    Q: What is the Main board?
    A: The main board (motherboard) is the core part of the hardware and controls all functions of the phone. Every part of the phone with a function is connected to this main board.

    Q: How can the main board gets damaged?
    A: The main board can get damaged from shocks (drops), dropping into water or even from pressure. Also, mainboard damage can also be caused by charging with a poor quality charger/cable. Damage to the main board can arise even there was no physical damage.

    Q: What happens when the main board is damaged?
    A: As the main board is the core part of the device, once it is damaged, it can make functions play up. The functions affected depend on the location of the damage.

Q: How do I know if the signal problem is caused by damage to the parts (reception signal cable) or main board damage?
A: There is no way to physically find out if main board got damaged or not unless you test the device with a new part and see if it is working properly with a new part or not.
With this matter, we can help you through a quick inspection and can tell you if it will be solved by replacing the part or not. Please click the link below to find your nearest Happytel store!
