I had the end call issue on my older phones Redmi 5A but it only happens on the whatsapp. Normal calls are just fine for the 5A. The A series are the cheaper models, it costs about $100. Now I'm using a Redmi 9. None of those issues anymore.
When it comes to bloatware, I'm fine with it since I don't install any heavy duty apps on my phone. I just have whatsapp, telegram, 2 games, 2 shopping apps and a few work related apps.
I'm writing this not to convince you, it's just people are so hardcore negative when it comes to China brands that they become an free anti-campaigners without actually using the products.
Some of you may be using Iphones or Samsung but for me I can't afford those luxuries, this cheap phone saved me when I was so broke and it helped me tremendously on numerous occasions when doing part time jobs and my full time.

But then this is reddit, go ahead an downvote me for my experience using Redmi. Damn the hateboner for anything remotely Chinese is insane.
