Google should not allow Redmi or anybody else to deactivate my Google account

Yesterday I log in to my elder brother's redmi mobile phone to upload a video into my you tube channel. My elder brother's mobile number is: 7002418926. But uploading of that video could not be completed. After that  I tried to remove my Google account by logging out from that Redmi device( note 7 neptune model) Because they hid log out/ sign out/ account removal button in that Redmi device. Now I am worried about my Google account- because at any may moment they may give command to elder brother's and my bhatija's brain to deactivate my Google account. Google should not allow Redmi or anybody else to deactivate my Google account (including my this blog and my you tube channel)
