So i replaced all wifi, bluetooth antenas and covers ( three parts exactly), because they didnt work. I tought that would fix the problem but still the same. Wifi greyed out bluetooth spinning around and automatically setting time is not working. but here comes the WEIRD —>When i try to open settings –> About … the iPhone 7 just stucks freezes. if i press the home button it returns to the home without problems. Also the sim card is working just fine having service and yeah… Anyone got something on this? #06# also not working
There could be three problems. The first could be that you have some outdated apps on your iPhone. Outdated apps slow down your phone in general if they are not compatible with IOS 11. Another possibility is that you have a lot of memory on your phone. I’d suggest clearing some up. The third I can say is that it might be the processor. Some devices take longer to load information or data.
