I managed to update my "Astro on the go" using Aptoide store.

Here how I did it.

i. Download and install Aptoide from http://m.aptoide.com/installer

ii. From the Aptoide Store, search Astro on the go (6.1.0)

iii. You will be prompted with "You don't have 'astro on the go' in your added stores." with "Search more" button next to it.

iv. Click the "Search more" button.

v. Select "Astro On-The-Go INT (6.1.0).

vi. Select "Install" button

vii. Another screen loaded (in the background) with "Do you wish to install:", select Yes.
Alternatively, after you have successfully installed the Aptoide store, launch the Aptoide and select "Updates" tab to update your old version of Astro on the go to the latest version.  Please try this method to see whether it work or not.

Folks, just wondering, what is the minimum speed to run astro on the go? Itchy to try.. but, not sure my UNIFI 5mbps is good enough for smooth streaming? Lagging is something unacceptable really, LOL.

Thanks for advice...

Streamyx 4Mbps still smooth.

What phone is yours?

When I try to install On-The-Go v5.3.0 using Google Play on my Xperia Z1, it's say not compatible. So I manual install the APK. (you may find my previous post here).

Last few days, when I launch On-The-Go v5.3.0, there a message say got new update and straight away goes to Google Play store.

From there I able to update to the latest version 6.1.0. 

Hi, can you help to provide 6.3.1 version ask? Appreciate it very much.. Thanks..

I try to backup what i have but when transfer to another phone, given error when install.

Any one have the Astro ON the GO APK? Please share, I am thinking to install with Samsung Home Sync. Thanks
