Hi @Bas143 Around 45 °C would be the normal limit, however it not too concerning. Just give time for the phone to cool down a bit. There should be warning if the temperature is excessive. When charging background apps should be shut down.
The device will heat up when charging and particularly when running power intensive applications, multitasking. During game play it is likely to get hot and should leave it for a short time afterwards. in all would only be worrying if it was excessively hot . It is advidsable to wipe cache partition after update , have you not noticed it to the same extent recently?
1. Turn off the device.
2. Connect To Computer , other Device or TV USB, Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.

5. Press the Volume down key several times to highlight wipe cache partition.
