I have been using zd box now for several years and it's one of the first apps I download when I get a new phone and I have used it on low-range to top end android devices and find it to be an excellent tool app which handles most of the tasks to keep my phone running smooth I highly recommend this app.
All in one It works as task killer, app lock, battery saver, android booster, app manager.
Way to improve. I improved it by uninstalling it!
All I have to say is that its amazing download it plz 😋👍✌
One of the best app All in one App does evrything Download it
