How much is my phone worth?

I have an IPhone six, the motherboard is broken, but the only thing wrong is that you can't call or text with it… It's basically a IPod. The phone repair store said that they could ship it off to get it fixed, and it would cost $120 to fix but there's only a 50/50 chance if it working. I bought it as a brand new phone from Verizon in September 2017. I'm just wondering how much I should sell it for? I just replaced the glass too. If you want to know anything else about it ask.

Over protective mom keeps tracking my phone ( i'm 19 years old male)?

So i'm 19 years old and my parents still track my phone with the share my location thing on iPhones, she tracks my every movement, and I'm home for the summer and can't do anything without her tracking me 24/7. And when I turn it off she flips the f*** out and I don't know what to do. My friends want to hang out but I can barely out past 8 o'clock without her getting an attitude and I'm a male. Also, girls would want to chill to and I like older women. I'm on her phone line but I pay my own bill. I can't tell the girls that 22+ " my mom said I can't leave the house". I don't know what to do. Any suggestions?

My iPhone 6s is glitching like crazy?

Since last night, my iPhone continues to constantly glitch with a purple and pink screen, and the outline of the screen is a bluish pink. Glitching lines keep showing up
Since last night, my iPhone continues to constantly glitch with a purple and pink screen, and the outline of the screen is a bluish pink. Glitching lines keep showing up on my screen and the entire screen keeps flickering. My phone can't stay on unless it's plugged in, and if it's unplugged (even though it's nowhere near having low enough power to die) it goes to this black and blood red screen with the Apple logo. And when I'm on one thing And move onto the next, there's still an outline of what I was on, a faded version of it and the keyboard is lagging.
