My Phone Redmi 9c, I've been using this device for almost 4 years and my parents finally bought me a new phone so i had to give my old phone to my little sister. I carefully handled my old phone as it lasted 4 years to my care, it had some rough crash but it really didn't damage the phone much, only my screen cracked and currently it's slow as hell but i got used to it. Sometime passed and i got a news that my phone is not charging every problem just starts coming up. I bought a new charger and fortunately i work but when i tried to open it, it's become slower and very annoying to do stuff in it and then, after meddling into it, it shut down on it's own. It happen very often that I can't even use it
