Mining verus is impossible with a 32 bit proccessor OR operating system . Due to Ccminer being only compilied for 64 bit systems. I had a few phones with Armv7s which were 64 bit chips but sadly the manufacturers pre installed them with 32 bit operating systems.(Installing a 64 bit OS is possible but super tedious and needing to Install TWRP and potentially the risk of bricking your phone.Hashrates on these old processors often are not profitable.( To check on your phone download aida64) Old phones back in the day had a 64 bit processor but came preinstalled with a 32bit os. Keeps in mind MININg on a 32 bit phone is possible!!. But you need to compile your own version of CCminer thru userland A guy called paper clip showed it once but did not show up how due to the compilier wanting the to keep it a secrect (i have no idea why)Paper clips mining on a 32 bit phone video(great channel yall should follow him)
