g530az taking over 10 minutes to Boot after water damage

Got this water damaged Samsung g530AZ

Cleaned PCB

phone takes about 10 minutes to boot to android.

after booting, it works fine, seems like no problem.

I installed custom recovery and formatted almost every partition except system
and keep having the same problem.

I flashed the phone and still have the issue.

over 10 minutes to boot every time you reboot the phone
