A couple of questions, first my Zenfone has been very slow from day one, any time I select an app it can take anywhere from 10 seconds to a minute for it to open the app and make it usable, which is an unacceptable amount of time. Second. Now my Zen when hooked up to a charger will not remain charging. After a minute or two, or 5 I will hear the low charge alarm go off, and I will check it and it shows that it's not charging. It's not the charger, it does the same thing on every charger I try. This is quickly becoming a nightmare and don't want to have to babysit a charging phone. What can I do?
