Hi. I have samsung galaxy j5. I don't know that is good forum to ask, but maybe android owners help. So problem is that after software and apps updates, in my phone space gonna lower and lower. Maybe there is dump files or something? I buy sd card and planing to make default factory restore settings, I dont that is good idea. Also I wanna ask should I need use antivirus, adbloker if there is? Maybe is something software like ccleaner or something? I hope maybe helps somebody. Thanks ;)
