A lot of the time when I press on anything, my phone spam-presses what Im pressing. For example, when I go to type a sentence, it would spam press those letters. So, if I said Hi, it would say Hhhhhhhiiiiiii. Please help!

Hi, Have you checked that your not pressing too hard. If your not, maybe it could be a good idea to check if the screen is damaged. Also is there a certain part of the screen that double presses. If that is the case, you will need to get your phone serviced

I have this phone too. It sometimes even freezes (or is laggy). How I fixed the issue on mine was by deleting app caches, deleting unused apps, and so on. When the internal memory is too low on space, it causes the phone to not work properly. I hope this helps!

Yes, this started happening to my device (of the same model) after I accidentally got water on it, this is called ghost touch. You will need to fix the screen.
