Hotspot between 7 plus and 12 pro max disconnect automatically also after resetting both phones.
Good Morning beautiful people,
I am sharing my internet from my iPhone 7 Plus to my iPhone 12 Pro Max using the Hotspot feature, both phones has the latest iOS and the same Apple ID, but unfortunately every time I leave my 12 Pro max for some minutes I found it disconnected, I tried to find any settings to solve the problem on both phones but couldn’t find, I did a clean factory reset using my Mac with the DFU mode but I still have the same annoying problem, anyone please know a solution please?
I already tried to use Bluetooth connection instead of wifi but the internet speed was very very slow ( on Bluetooth I receive 0.2 to 0.5 Mb/s but on Wifi Hotspot between 20 to 50 MB/s) and I tried to connecting using Bluetooth and Wifi, the Wifi will disconnect automatically also.
Thanks in advance.
iPhone 12 Pro Max, iOS 15
