What is google go? I downloaded a few photo galleries for my default, they seem working excellent - DV Gallery it works wonders, basic app settings click on the "Allow access this to your gallery." Boom there you go.

 

And why wouldn't you want to use Google photos? It backs up every single photo to the cloud, free. If your phone ever gets lost or broken, boom! You're SOL without a backup.

 

Trust Google Cloud! And you can download your photos offline too Believe us, saves our black outs, when the phone is dead as well as even, saves when we are in a black out too

 

Google Go is a smaller, more space and memory effecient version of Google, designed for low end devices.
It will still work on better devices.

Think of it as a 'Google Lite'.

 

Try this...

Open your file manager app and find a photo, any photo.
Tap on it to select it.
If there is no default app set to open the file, a list of available apps to do so will appear and you will be asked to make the decision.

After you do so, and the file is viewed, do this procedure again.
This time, when the list pops up, you should have the option of 'open with always' or 'just once'.

If you select 'always', then that app will now be set as the default.
