After reading so many posts I dont know if I feel better that I am having the same continual issue or not. I have had my new iPhone 11 for about 5 weeks now. Reset it twice, had it replaced with a new phone once, had a new SIM card replacement and still have continual issues. Not only the WiFi connection dropping out every 15-30 seconds and having to reset the network everytime to get a connection for another 15-30 seconds but also the screen blacking out in the middle of calls, middle of using the phone on apps and just looking at photos. This is the worst phone I have every had from Apple and given most of us rely on this for work and I am now stuggling to do business with my clients because my phone just hangs up on them, I could not be more disappointed. Apple store blame Optus and say it is not the phone but given the threads I have just read, I am certain it is a major fault in the iPhone 11.
I am currently travelling overseas, and how frustrating is it that I am having so many issues with the phone. It is costing me so much money in roaming data charges because I cannot hold a WiFi connection for longer than about 30 seconds. When I get back to Australia I will be taking the phone back to Apple and requesting the iPhone 10. I cannot afford to have issues that impact on my business due to a phone which clearly is very unreliable even though it has been out for nearly 6 months.
Apple...I cannot believe after all that I have read and the issues that so many people are having, that you have not sorted this and done a recall or something. That is not good business on your side of the fence.
I guess as you hold a big space in the mobile phone arena, these threads mean nothing to you so you sit on your hands and do nothing clearly. If this is the technology you are moving into the future with, I may need to bit the bullet and move to another mobile phone supplier and move away from Apple all together. I can now appreciate why others have done this in the past.
