Did you hold down power+home while screenshotting?

Probably. I don't face this problem, so swapping it out is your best option. Although, you can try factory resetting to see if it resolves that problem.

Note 5 Duos (Black Sapphire) - 1440 x 2560 pixels (~515 ppi pixel density) - Exynos 7420 - 4 GB of RAM - 32GB storage Currently liking this phone, since I upgraded from Note 3. Don't really think I will flash Cyanogenmod (If there is one in the future) as I would lost some features that came with the phone. Alot of people bash on this phone for it's non-removable battery and no external sdcard expansion, but I don't use more than 16GB of storage and I don't really see any purpose for me to remove the battery when I have a portable charger in my bag. There are still some bloatware which I prefer it be gone totally than me disabling them, but they have lessened the amount of bloatware since the Note 3.

Alright, thanks for taking your time to solve this with me.

While connecting to my pc, it just says the "USB device has malfunctioned" I also have removed the battery, performed the "Freezing the battery" test, but it was not effective. Perhaps replacing the battery could fix this problem?

It was a Note 3 charger. I didn't had a free port so I just used my note 3 charger at that time to charge my Nexus 5. I been doing that for a few months though.

It was on when it was charged It was laying on it's back side (Meaning screen upfront) I live in a tropical environment (Singapore). Probably the dumbest move I did, using a Samsung charger brick while using the Nexus 5 usb cable. I had it for a year.

My Nexus 5 is not switching on after I charged it overnight. No matter what I do (Disconnecting the battery, holding power + both volume keys), it wouldn't switch on. I still feel warmth near the camera while charging the Nexus 5. Any idea what could fix this issue?
