iPhone 11 Pro Max overheating and freezes.
Hi, I have a very big problem. One month after I bought this phone I was on Instagram when suddenly the application crashed(whole system was laggy) I closed it and reopened it (at that moment I had 5-10 FPS). I have this problem for 4 months now and it's annoying. I did an Antutu test and noticed that it has a much lower score than a normal iPhone 11 Pro Max. What should I change? I want to mention that I don't have an apple store in my country. Maybe the battery is damaged or something broke on the chip? It's my first iPhone and I'm scared.
