Which version of Redmi note4miui is better, 9.6 or 10.2?

For Redmi Note 4, the choice of MIUI version usually depends on your personal preferences and needs, as well as the performance of the device. Here's some information about both versions to help you make your decision:

MIUI 9.6: This is the older version and is probably more stable since it has been tested and improved for some time. If you pay more attention to system stability than the latest features, MIUI 9.6 may be a good choice. But be aware that it may be missing some new features and security updates.

MIUI 10.2: This is a newer version that usually brings more new features and improvements. If you want to experience the latest features, interface and performance optimizations, then MIUI 10.2 may be more suitable for you. But please note that new versions may sometimes introduce some new problems because they may not have been fully tested and optimized.

The final decision should be based on your specific needs and preferences. If you care more about stability, you can choose MIUI 9.6. If you like trying new features and are willing to deal with some potential issues, MIUI 10.2 may be a better fit. Regardless of which version you choose, though, it's recommended to back up important data regularly just in case something goes wrong.
