I'm not sure I was clear enough with what I typed, so I'll try again.
All cheats can be entered anywhere, at any time, but for most of them the Console and V-ko are the easiest places. Unless that is different for Android. clowncar or tistheseason are probably the easiest to test.
For some reason, anotherbrickinthewall does not work when typed into a textbox, so you have to type it elsewhere.
When I said typing in the Codex screen, I meant the screen that appears when you first open the Codex. The one with "Stats - Log - Extra - Options" at the bottom.
anotherbrickinthewall is deceptive in that the 100K does not appear right away so you don't know immediately if it worked. You have to do something (move a square, open or close the Codex screen, pretty much anything other than look at your inventory) before the 100K will be added.
Also, money ceases to be a problem once you reach Zheng Shi. The Mining Robots consistently drop valuable Gems and Savicite, and after defeating the Shock Hopper, you can make a custom bet of all your money at the Robot Blackjack dealer to double it. And the best ship in the game is free (although if you want to keep the Casstech, you'll have to buy a different ship from Vahn, fly it Zheng Shi, then steal the Sidewinder). At this point, I'm more worried about inflation.
