Phone displays battery charging, won't turn on

My carrier is AT&T business plan. I got behind on my payments and after using it all day without issue, my phone showed that there was no network connection around 5pm. I didn't know why at the time so I went through the power prompts to restart. The phone turned off and has never powered up again. I immediately paid my balance and fixed my ATT account with other phones on the plan working fine, and my sim works fine in other phones.

When the phone is completely dead, I plug it in and the screen shows the normal charge initiation, shows normal charging vs super charging and will count up all the way up to 100%. If I plug it in at any point other than 0%, it will not acknowledge that it is being charged, will display nothing. Pushing the power button, holding it down, tapping the power button multiple times, holding it down with the vol + or vol - combo, "massaging" the screen, the phone does not respond, doesn't vibrate, doesn't display the Samsung text or anything else...it's is a dead brick at any %. I've done every troubleshooting tip with the exception of taking it apart.

The only other thing to mention, whether it's relevant, is that the phone had fallen in the toilet months ago, was dried out and working normally with the only issue being since then, 98% of the time, it wouldn't start a charge unless powered off. Once charging, I could turn it on again, do whatever with it while plugged it and it would continue charging fine. If I unplugged and plugged in again within a few minutes, it would usually continue the charge but 5mins + I would have to shut off, plug in, wait for the charge to initiate, power back on.

Any chance this phone can be saved??? Thanks in advance for any suggestions.
