Step by step

1. 

   Tap OS version repeatedly

   Go to Settings, About phone. Tap OS version quickly, several times in a row, until a message says you are a developer.

   Done

2. 

   Already on?

   Our phone already had Developer options on, so tapping OS version showed No need, you are already a developer.

   Done

3. 

   Open Developer options

   Go to Settings, Additional settings. Developer options is listed there, below Accounts & sync and Enterprise mode.

   Done

4. 

   Change only what you need

   The list is long. Animation scales, for example, are near the top of the drawing section. Ours were all at 1x.

   Done

If you do not see this option

• No Build number to tap? Android's own instructions say to tap Build number. On our Xiaomi, OS version in About phone does the job instead. We have not checked older MIUI phones. Source: Configure on-device developer options
• Developer options not in Settings? It is in Additional settings, not in the main Settings list.

If this does not work

• Want to hide it again? Developer options has a switch at the top to turn it off. We did not turn ours off, so we have no picture of it.
• Phone slower after changing something? Set the three animation scales back to 1x: Xiaomi phone slow or lagging.

About this guide

Developer options holds advanced settings, such as the animation scales and USB debugging. On Xiaomi it is turned on from OS version, not Build number.

The screenshots are from our Redmi Note 15 Pro 5G with Xiaomi HyperOS 3.0.308.0 and Android 16, in Light mode. Developer options was already on for our capture, so our picture shows the already a developer message. We only opened these screens and changed nothing.

In short: Settings, About phone, tap OS version until you are a developer. Settings, Additional settings, Developer options.
