Hi there, I hope you all are doing great.

I have a Samsung Galaxy A21s (4/64)GB mobile phone and I need its complete motherboard diagrams for repairing purposes because my phone sank into the water and after that, the SIMs are not working on it I cannot make or receive calls on my phone, it always shows "Emergency Calls Only" with sims inserted in it.

Moreover, the radio frequency (RF) signals of SIM networks keep coming and going. The RF is not stable so the mobile repairing mechanic said I needed its motherboard diagrams so he could correctly locate the root issue in the board and fix it.

So I request please help me in this regard if someone in this community has that motherboard diagram please let me know I'll be very much thankful to you.

Thanks & Kind Regards,
Usman

Not our area of expertise, plus that phone is so cheap its going to cost a lot less to buy another than pay a repair shop.

From what I can see the Samsung Galaxy A23 5G is even cheaper when buying new.

I'd say the chances of getting hold of a diagram are next to none, and as Alex has said it's not economically viable to repair it anyway - certainly not in the UK anyway.
