It’s almost 3-4 months nothing phone 4a to switch between ultra wide - main - telescope lens in 3rd party apps like ( Instagram, Snapchat) , but no updated for 3a series and older. That not a fair thing if people are trusting nothing, you should atleast show some respect as a gesture of giving timely updates.
I wish 3a series soon get’s a update includes this basic features of changing between lens.
