So conflicted...

My phone is a Nokia 6120c, bought two years ago for 1,000 yuan. At that time, Android was just starting here. Two years later, 99% of people here use Android touchscreen phones. I'm the only one still using a Symbian keypad phone. During the summer vacation, I wanted to get a summer job, but because my mom injured herself, I had to stay at home to take care of her and do some small crafts. Now that school has started, I notice everyone around me is using Android or Apple. No one uses Symbian, and even fewer use Nokia. Some people look at me using a keypad phone with a face full of disdain.
\ I was just listening to music with headphones, but the phone kept automatically activating voice control commands. It would automatically activate every few seconds.
I've confirmed that the phone has no virus.
It's definitely the phone that's broken. There are no Nokia repair shops nearby, and even if there were, I wouldn't want to get it fixed, as the phone has already been used for two years. Now I can't open two apps at the same time; if I do, one of them will freeze. I want to buy a better Android phone, but my mom's leg hasn't healed yet. The family's financial situation isn't great either, so I'm embarrassed to ask my parents for money. But this phone really can't be used anymore (if you don't believe me, go ask someone who's used the 6120c for two years). It's too slow, the memory is too small, the screen is too small. It restarts automatically, goes black or white randomly. It gets extremely hot when used. I'm conflicted… Should I get a new one or not…
