Samsung Galaxy Note 3 keeps restarting after boot

[Android Central Question]

Hello, I'm new here and first time posting a question. I searched all other related topics and didnt manage to find a solution for me. So here is my problem I hope that someone can help me. I have a Samsung Galaxy Note 3 and here's the thing. It crashed few days ago so I just replaced the screen. After that it couldnt manage to boot because it was stuck on a bootloop. I couldnt even reach recovery mode because it kept rebooting even before it gets there. I only could go into download mode so I flashed the stock rom with odin and everything went fine, phone started to boot normally, recovery mode fixed as well. I performed a wipe data factory reset and phone seemed to perform normally. But here's the problem now. Although it boots and starts normally and it seems pretty useable, now it reboots itself always nearly 10-15 secs after getting into the android. And this loop goes on and on. I cant really find a fix. I tried to wipe cache but nothing. I should say tha the phone functions fine and I can use it normally into the android os till the moment it reboots. Thats all, sorry for this loong story I hope someone can help me. Thank you in advance!

Welcome to Android Central! There might be a loose connection somewhere, perhaps related to the Power button. Or there's an off chance the battery is failing. You could try a new or different battery as a test, but for the Power button, you may need to bring it to a repair shop.

I suspect that it's something due to the screen replacement. If you did it yourself, you'll have to bring it into a repair shop to have it diagnosed and fixed. If a shop did the replacement, just bring it back to them and ask them to fix what they broke. (I'm assuming that, since you say it runs until it reboots, then you can start it again and it runs until it reboots, the battery has enough charge to last for more than 10-15 seconds.) It is possible that you replaced the power button in some strange way that it's causing a reboot, but the same amount of time each time would say no. It's more likely something on the motherboard (a loose connector, a crimped wire, etc.
