Google has expanded Smart Compose from Pixel phones to most other Android smartphones. And although it may be convenient, it can also be annoying if the suggestions are disabled. If you do not like it, disabling is a simple process.
Smart Compose finishes your sentence for you
Smart Compose should not be confused with Smart Reply. Smart Reply checks the e-mail you have received and suggests quick answers that are appropriate. An email asking for a meeting tomorrow might lead to a smart reply suggestion such as "That would be great", etc.
Smart Compose and others are holding hands , is for the email you are typing (see head of this post). Think of it as something like Swiftkey on steroids. The difference, however, is that Swiftkey tries to predict the next word you will type, and Smart Compose tries to predict the rest of your sentence. If you have entered the following: "I am free for myself", Smart Reply may suggest "On Saturday Unix". If you like the suggestion, you can click directly on the words (not your keyboard) to accept them.
But not everyone is a fan of predictive text – you may find it annoying or intrusive, or it does not suit your style of writing well. Thankfully, Google provided a simple process for disabling Smart Compose.
Disable Smart Compose
Open the Gmail Android app and tap the Hamburger menu in the upper right corner.
Tap on "Settings".
Tap an e-mail account (you must repeat this process for each one.) E-mail account).
Scroll down to the Smart Comose option and tap the box to turn it off. You can also disable Smart Reply here if you want.
When you're done, you should not see the suggestions for Smart Compose. If you have more email accounts, repeat the process for them. And if you choose Smart Compose suggestions, just check the above option.
