My camera can take up to 10 seconds to open. I have tried deleting all possible cache, deleted apps to make space, deleted all photos from album and backed up to Google photos. Also deleted cleaner app as read here that can slow things down. None have worked but if did clear some space so allowed a system update which had been pending and it seems to have made things worse and now my WhatsApp and Viber are taking the same length to open. Please help!
