i was given a used smartphone this past year. i would like to have a working computer of my own again. one thing i have done is taken the battery out of it when carrying. and sometimes set it away from me. also i have heard that the government can turn on phones remotely if they want. since changing food recently i have been trying it some, since libraries closed on holidays. and, those things would make me sick. i have been trying to get screen darkener program to see if that helps.
