So a few days ago, when I got up in the morning for work. I noticed my phone was off, even though I leave it on the charger turned on.. Turned it on, and got a message , the phone was powered off because it detected it was overheating.. Weird? While coming home from work, I had it plugged into my car charger and it seemed fine.. Was up to 69% once it was unplugged, it went down to 49% in 10 minutes.. Put the phone back on the charger in the house, and after a couple of minutes it powered off again.. That same evening went to use a different charger from the wifes Samsung work phone.. The phone would not charge, but would charge hers.. I tried a different charge block and her power cord.. it would show for the phone to reach 100% from 61% 3+ hrs. A couple of seconds later it was not charging.

Ok, tried a different charging cord, and my wife's charging block.. Time to reach 100% 14 hr 57 min..So today I took it to a Samsung repair center not far from my home.. They told me, the phone would not connect to their computer so they could diagnose it.. it was charging fine, so the told me the main board was bad.. They are ording one and will install it next Tue. I never had a issue with my other Samsung phones overheating, or needed to have the main board replaced..

I will say this.. Best Buy is suppose to be a Certified Samsung repair center.. But what I found out, they only service their Flagship phones.. I asked Samsung directly. when I called them first about the overheating issue, before bringing it into them.. Best Buy does not have all the tools to fix all their phones. But they do have all the tools to fix all their flagship phones???????? I find that odd for sure.

I purchase this phone, because it suits my needs.. I have always have flagship phones, but they are not needed for me at this time.. I'm was so pissed about this issue, and first getting alot of running around from different sources about this issue. I was almost ready to trash the Samsung and android all together and go Iphone..

Best Buy is a certified Samsung repair center. It is posted on their website. They just seem to do their high end phones. They also are listed as which devices they fix. Which is Samsung latest flagship phones S9+ and up.
 
When I started to read this I was constantly thinking this is a battery issue because its charging is so erratic. Now I wouldn't normally question the repair centre but I'm not certain how the main board would cause this. You mention charging a lot but not if the device can be powered on or used. If it can then theres no way there is a main board issue. Virtually all Samsungs have a secondary board which handles power and since your issues seemed power related, I would have thought that would have been culprit number 1. Anyway, I hope they informed you about data loss? The mainboard contains the storage and if they say it won't connect to their computer and you can't power it on for a cloud back up then you will lose all data.

The phone powers on and off just fine.. I purchased a new charger as I had mentioned I think my other one was overheating because of heavy use.. They said the main board and charging port will be changed. The main board because it will not connect to Samsung's computers fo they could diagnose the issue.. I'm not worried about losing any data, as all my stuff is backed up...

Fair enough. Good luck with the repair. Hope it fixes the problem!
