There's another gathering of integrated circuits on the flip side:

Murata KM7N07016 Wi-Fi/Bluetooth module

NXP PN80T NFC controller

Qualcomm PM845 (likely PMIC)

Qualcomm SDR845 RF transceiver

Hard to make out, but we think this is likely the same Skyworks SKY78160-11 front-end module we found in the S9+

Qualcomm PM8005 PMIC

Qualcomm QDM3870 high-band diversity front-end module
