My advice to punters is keep things as low tech as you can, I use a second hand old mobile which is sufficient for my punting needs. I wouldn't use an Android phone for punting but then I use that old fashioned thing called pen and paper to write down WGs numbers etc then can rip it all up if necessary. Never yet been caught out in over three decades so it works for me, though I wont ever get complacent as that's what caught a punting mate of mine out.
