I installed SD card from my last blu phone.I'm not sure that I don't need to do more. SD storage indicates only 2 apps and 1 In ever installed. I k ow there was more on that card. ( format and mount? ). I also went into developer options and think I may have changed something, just not sure what. Really don't want to do factory reset. I' m just learning where everything is. I am SO tech handicapped. Thank you for any help you're able to provide.
