The OP told us he bought the Pi several weeks ago, so he is entitled to a refund/exchange from his supplier if the Pi is really defective.

Re: 5V 5A power supply, yay or nay?

Except that much more smoke escapes when you manage to create a short, and not to speak of what will happen when you switch the supply on, and for a short while the output goes over 6Volt (Hint: much more smoke). the PI should get no more than 5.1 Volt. https://www.raspberrypi.org/help/faqs/#power ...

Re: Debian on Pi 3B & 3B+

A Raspberry boots from a SD FAT partition, this is where the software (KERNEL*.IMG) for the GPU is stored. The GPU takes care of the reading of these fles and loads this in memory. Only then the ARM processor is activated. Quite a different approach than on PC's for example, where a BIOS for the CPU...

Change the SD too, it is vulnerable due to wear out.

And in the (unlikely) cause it is dead, one per customer' in practice means one Zero per order per day per supplier.

Re: Pi 3B+ Improvements?

The CPU clock on the 3B+ runs at 1.4 GHz, on the 3B at 1.2 GHz.

No changes on the GPU side afaik, not in performance nor capabilities.

So if the CPU is involved in creating graphics, some improvement in speed will be seen.

Re: Raspberry Pi Zero Wifi signal gets bad after time

What you describe sounds more of a resource problem leading to slower response. You did not tell us what software you are running, or whether you started with a fresh SD card on your second Pi, so I guess things to check: - SD card wearout - SD card corruption - does the camera store images on the S...

" but camera should be able to take clear pictures in low light conditions."

This rules the Raspberry Pi Camera Module out I fear. The NOIR variant may work better here, but with the obvious IR coloring.
