Hint: Real answer flag is not easy to get it, if your post flag is incorrect, it is not real one. Please try to analyze more.
With some recon, we knew the APK is built with Unity. We used Unity Unpacker to analyze this APK and found this interesting asset.
We tried to submit SECCON{Y0U_4R3_34CH+3R?}
but failed. My friend suggested that the word is cheater, and tried to submit SECCON{Y0U_4R3_CH34+3R?}
but failed again. Then I tried to fix the grammar, and we got the flag!

Kami mempelajari bahwa APK dibuat dengan Unity. Kami menggunakan Unity Unpacker untuk menganalisa APK ini dan menemukan asset yang menarik.
Kami mencoba submit SECCON{Y0U_4R3_34CH+3R?}
tetapi gagal. Teman saya memberi ide kalau katanya adalah cheater dan mencoba untuk submit SECCON{Y0U_4R3_CH34+3R?}
tetapi gagal juga. Kemudian saya membetulkan grammar-nya, dan ternyata mendapat flag!
