FLASHING PHONE SCREEN

Hello my name is Deanie Coplen, phone number 254-218-9320 & I am having issues with my phone screen. It keeps flashing and gives me terrible headaches. I didn't get the insurance on it but I was wondering what could be done for cheap? I've been with y'all for a little over a year now and I know my next upgrade isn't until feburary of 2021 I believe but I was just wondering if there is anything we can get done since covid 19 has me short on money. Thank you.
