I don't think it will be wise to run Bitcoin core on mobile device Linux as it takes a lot of time to synchronize with the network and consume a lot of internet. Do you think a mid-range device can handle this pressure? It needs at least 50 GB of free space even if anyone tries to run the pruned node. Forget about downloading the whole blockchain. Most mobile device comes with 64 GB storage if its RAM is 4 or 6 GB. Even a device with 128 GB storage won't be sufficient for this because most of the time the system takes up a lot of space. if you are an Android user, you should know this already. Even if anyone runs Bitcoin core, it will take ages to get syncronized.
You are right, Shishir99. Even if it were technically possible, I don't think we should run something we are unsure of. I could have installed the Bitcoin core and given you (PrivacyG) feedback, but just as Shishir99 said, you will run out of storage before you know it. I had to free up 20 GB of storage before the installation. And after the installations, I only had 5GB of storage left. But yes, if you have an 8/256 GB variant phone, then if you want to, you can give it a go. I don't know how to install Bitcoin Core, so I didn't. But again, I think that's unreliable. Using Kali Nethunter on an Android device for a long time can be unreliable. There can be app crashes, low memory kills, lags, hitting issues, etc. Nethunter can be quite handy in the hacking sector, to be honest. You run some tools, test, expoloit, etc. Or you could use PGP encryption (if it supports it). How much time would it take? Max 10 minutes, I guess.
Kali Nethunter is the perfect solution, for those who wanna, at least have a taste of Linux operating system on Android.
