These days, I really disappointed for using bad quality android phone with low specification, low memory, slowness, internal storage shortage, etc. If you compared with Apple produce, the experience is very quite different. Probably because I’s using cheap android phone, Ace 2. I found newest model like Note 3 or S4 can handle many apps and cause no slowness. But I cannot afford to buy new phone now.
But, these awesome developers made custom ROM ,4.3 for Ace 2. Thanks to them. These time with this new ROM, I should reduce apps, unless it will be slow again after many app installed. Although there are some bugs such as sometimes power button is not working, Google Book crush, it is still awesome and worth to use. No app is perfect.
