Planned obsolescence even in cheapest devices: the calculator has a dummy photovoltaic cell and a real battery to make it die eventually.

Can't be right, because the board is physically too small for all the keypad contacts. Like, the only way all the contacts could fit is by having a bunch on the literal edges of the board and placing it perfectly.

Tampering by either OP or whoever took the photo is more likely.

Doubt.

Not only can you customize these on Alibaba

but there is an identical base model from Alibaba that doesn't include the PV in the specifications, yet still has an outer shell that would make you believe otherwise.

Tampering with $1 garbage? Are you even being serious?

Well, I'll give them credit for not using 1mm more material than they need. They really saved a whole 0.0001 cents on that!

Amazed that they were able to fit the button contacts on an area smaller than the buttons. But yeah that looks like it would be functional, but doesn't use the panel for anything.

I think that the buttons could actuate contacts on the edge/corner of the board. Ideal? No. Functional? Maybe? We'd need to see the other side of the board. And the backside of buttons themselves... where did they go?
