Hello first of all, I'm from the Philippines.

My samsung galaxy s7 edge had a problem powering on. There used to be a blue light and i've tried all remedies found in online such as pressing volume button, etc it didnt work.

So i had to go to a repair shop and have it checked. The technician said it was the motherboard problem. I was not planning to invest so much on a defective phone so it took awhile to make a decision. At the end, i let the technician replace the motherboard and my phone seemed to be working again.

However, on the same day when i got home, i tried observing the phone and it asked for a firmware update. It was unusually getting a little hot too (like my phone with original motherboard did not have any issue with overheating) So i clicked ok and went on. That's where the problem occured. While updating, my phone suddenly turned off and it wouldnt turn on. So i went back to the technician on the next day and as he checked upon my phone, he said it was the battery problem.

I mean, can you really believe what hes saying? At first he said it was motherboard problem and later on, he says there is a battery problem also. He also told me not to update the phone anymore because the new motherboard does not match with the recent updates.

I just trusted what he told me back then. Without having my battery replaced i just got home (i didnt want to risk anymore) and my phone seemed to be working again after he tested it. So i just let it open until the battery ran out. I have to admit, for few months, i did not care about my phone anymore and left it like that. But just recently, i started remembering it and i was able to charge it but it wont turn on again.

I went back to the technician for the third time. And he said the same thing to me it is the battery problem there is nothing wrong with the motherboard. When i got back home, i charged the phone 100 percent and seemingly it was working. I mean the battery doesnt seem like a problem to me. It seems more like a motherboard problem.

When i tried resetting it, it rebooted all of sudden in the middle and after finished resetting, i turned it off first. Now when i turned it on, it got stuck with samsung logo and started getting SUPER hot. Like i got so scared it might explode.

I really dont know what to believe.

I am getting skeptical about the technicians diagnosis.

Could someone tell me if its a battery or motherboard problem?

Thanks in advance.
