About “Android is Starting” message

Well many users have asked this question, what is ‘Android is starting’ error?

Even I have received the same error message once when I was using Android device of OS 5.0.

The actual reason is that when you install any apps and after that when you boot or when you perform, a factory reset then your android device recognizes the apps, which are installed, and this is where you can see “Android is starting” or “Android is Upgrading” message on your screen.

Practical scenario

I recently updated to Lollipop on a Moto G (1st Gen).

It was running a bit slow, so I wiped by cache then performed a factory reset as recommended.

I now receive the ‘Android is starting optimising app xx of xx’ every time I boot.

Obviously not life and death, but it’s annoying to have to wait 10 minutes for every reboot.

Is this a known issue and is there any way to fix this?

The actual message what they used to get on their screen was “Android is starting. Optimizing app 1 of x”. Here the ‘X’ represents the number of apps installed on the device.

How to get rid of “Android is starting” optimizing app error?

Well, I have gone through various forums and discussions. All have asked almost the same questions like:

No button works, the battery can not be removed, because it is an in built. It’s been tuning for the last 28+ hrs. but doesn’t count on.

Help me please….


I tried forcing it to shut down then doing a factory reset but it won’t let me get that far. It shuts down, restarts, and goes back to the same screen.



After going through the answers on several forums, I have come to know that this problem is rare and restarting the device can help to fix the problem. But some users have faced the similar situation after restarting the device.

Even many of them mentioned that downgrading your device OS from 5.0 Lollipop to Kitkat 4.4.4 could solve the error. However, this may be useful but I know that most of the user never wants to downgrade their android OS 5.0 rather they want to enjoy it.
