Upgrading Oppo Reno4 to Xiaomi 14T Pro

Today I upgraded my Oppo Reno4 smartphone to a Xiaomi 14T Pro model. The "old" Oppo was still good, but the offered price for the 14T Pro was too good to say no.

I already own a Xiaomi Tablet 6, with which I am very happy. So changing from OnePlus / Oppo to Xiaomi was an easy choice. Add to that, that the Oppo did no longer receive kernel updates, and OnePlus / Oppo no longer sell their devices in Germany due to patent trolls.

The specs.

Linux kernel after one HyperOS update according uname -a:

Storage is plentiful: 12 GB RAM, 512 GB SSD. As usual, some of this storage is used for internal purposes and therefore not directly available to you.

A good review of the smartphone is here: Verdict on the Xiaomi 14T Pro.

A video review of the camera of the Xiaomi phone is here:

Observations so far:

1. The fingerprint sensor is reacting very quick, way quicker than the Oppo fingerprint sensor. That's good.
2. There is no double tap to lock the phone, but you can use: Additional setting - Accessibility - Accessibility menu. With this you can activate something similar.
3. The 5,000 mAh battery seems to deplete faster than the 4,000 mAh battery of the Oppo phone, i.e., the Oppo phone lasts longer. That is unexpected and bad.
4. The Oppo phone (7.6mm) is clearly slimmer than the Xiaomi (8.39mm). It is also lighter: 209g vs. 172g.
