Can I run Stockfish with old Snapdragon phone?

[Jouni]

CPU Octa-core (2x2.73 GHz Mongoose M4 & 2x2.31 GHz Cortex-A75 & 4x1.95 GHz Cortex-A55) - EMEA/LATAM. I tried to run Android builds from Stockfish ARMv8/7. I got message "no application to run this program".

Hello Jouni, you never installed Stockfish on a phone? There must be enough instructions to find about that here on the board. Memory is very rusty. Google says Android is probably something like 9.0:

If that is the same phone, or thereabouts, it is not very old. Just follow instructions, even from AI if you must , you probably need to first install a proper GUI because Stockfish will not run on its own. That's why the message I think.

Android is 12. I am only interested to run bench and speedtest from console. Is this possible? No GUI needed.

[Eelco de Groot]

Probably not, Android don't like that sort of thing...

If you are somewhat familiar with Linux, install Termux.

I can see speed with DroidFish and SF14. But is it using only one core? Settings has no cores thing?

[Archimedes]

This works in general, although the results are not very accurate. When I do this in DroidFish, I always wait 10 seconds and then look at the number of nodes per second. But it's certainly enough for a rough estimate.

If there is nothing listed under “Manage Chess Engines” and “Set options,” then it is likely that only one thread will be active. That is also the default setting for Stockfish (and most other chess engines).

OK I finally found engine settings. And speed with 8 core and SF14 is about 1500 knps. With classic evaluation 4200 knps. Start position. Really respectable results for 2019 phone!
