• Transition animation scale (0.5x)
• Animator duration scale (0.5x or Rec.)

2. Display of battery level in percentage

On some models (like the Redmi Note 11), the percentage of charge is hidden to return it:

1. Activate Battery Status (or Battery Percentage)
2. Choose the display style: inside or next to the icon

3. Compulsory 4G/5G Entry

If the smartphone is constantly switching between 3G/4G, you can fix the priority network:

• Go to the Mobile Network → Preferred type of network
• Select LTE only (4G only) or NR/LTE (5G+4G)

4. Permission OEM-unlock

It is necessary to install custom firmware (LineageOS, Pixel Experience):
