Thanks.
What additional information would be useful?
Under Settings> About Phone it lists the following:
Device Name: Note 12
MIUI Version: MIUI Global 14.0.12 (TMTMIXM)
Android version: TKQ1.221114.001
Under Detailed info and specs it lists:
Model: 23021RAAEG
Is there any other information I need to provide and, if so, where should I look for it?
