I have a Redmi2 and after opening the app, using it a little bit, it closed. It happened 2 times, 1st when I opened the app and clicked on Facebook logo, later while I was reading a post on Facebook. I tested 4 browsers (Brave was the 4th) and two of them are closing without message, it just closes.
Device: Xiaomi Redmi2 (1GB version)
Andoird version: 4.4.4 KTU84P
MIUI version: MIUI Global 8.2 Stable 184.108.40.206(KHJMIDL)
If you guys need any other information, let me know.
