Different results of room correction on iOS and Android

[Vladetz]

Hello all
I have noticed that i get absolutely different results of measurements and room correction on 2 devices: iPad Air (2022) and Poco X6 Pro
Results from iPad are very close to REW, but Poco is a way off
I am using Dayton iMM-6C with calibration file in all cases, position, volume level and all possible settings are the same
Pictures 1-3 - iPad, 4-6 - Poco, REW without EQ - 7
FDW is disabled
OS and app versions are latest

Setup: Wiim Ultra - Topping E70 Velvet - Topping PA7 - Mission

I have also made measurements on quite ancient Xiaomi mi a1 and results are very close to ipad, both with iMM-6C. Also you can compare them ipad built-in mic
1 - A1 with iMM-6C
2 - ipad with iMM-6C
3 - ipad built-in mic
