Poco Smart Phone Heating, Locks Itself, Speaker Is Problematic

Muscles, phone heating, locks. Low sound when speaking with the speaker. It has been constantly problematic since the day I bought it and I am not satisfied in any way. It is not worth the money given. I've been having trouble since the first day, I don't expect any solution because I've given up on this phone and this brand, I'm just writing this complaint for those who want to buy it. I don't want them to have the same problems, so social responsibility...just don't fall for the same trap I'm stuck in, this thing is not giving you what it should.
