Hi, my phone actually is Xiaomi 8A but there is no option for it on the site. Last week, I dropped my phone on the floor. I did not think much of it and I've dropped my phone countless times before. This time, I noticed my mobile data strength doesn't stay the same, it goes weaker then strong and weak etc. I've tried some solutions but get no results. I placed my sister's phone on the same spot as mine which got good signal and strength while mine doesn't. We both use the same data provider. Any help is appreciated and sorry for my bad english
