Not every new feature is a winner. Sure, Hangouts is a brilliant messenger on Android, but it can be buggy and bloated when loaded in your Gmail. If you’re sick of it crashing your Chrome tab, there is help at hand: you can go back to good old Google Talk.
Hangouts is now the default messenger in Gmail, but you can still use the old view by clicking the little drop-down arrow next to your profile pic in the chat pane, and clicking “Revert to Old Chat”. Follow the instructions and you’ll be back to good old Google Talk before you know it.
Of course, this means you can’t participate in Hangout Calls or group chats, but you can just switch back and forth easily whenever the need arises.
