Please Excuse My Dear Aunt Sally, she downloaded a shitty ad-infested calculator from the Google Play store.
Unfortunately, it's the best calculator I could find so far (for my own needs). I paid to remove the ads though, ads bother me way too much to use something infested with them.
If you're willing to pirate (or legally generate) a TI calculator ROM, then Graph 89 is probably what you're looking for. This is what I use as my daily driver calculator with a TI-89 ROM.
Graph 89 with my TI-84 Plus Silver yields the bad answer
