I dropped my phone from the third floor
Surprisingly it doesn't look like it did, thanks to a screensaver the screen hasn't shattered and it seems to be working well, but from the top, the phone seems to have gotten out of itself like the screen got unstuck from the plastic frame, but nothing seems to be broken, the headphone jack got a knock where it became tighter therefore I can no longer use my headphone jack. First two days, my wifi antenna seemed to be working fine, then, I started to get the wifi dimming problem, I would restart and it would work back again, till restarting stopped working, I tried the reset network settings trick and surprisingly (again haha) it worked, but then that trick stopped working. What can I do? can I just repair the wifi antenna? Also, in addition the phone is starting to get all weird, like it would sometimes freeze then I would have to force restart. I'm absolutely gutted about this but can it be fixed somehow? I don't have the budget to buy another phone (looking at the fact that I bought this iphone 6 less than a year ago)
