moritz.ebert, May 23, 2019 : Hi all, since the last few months my 5 is behaving strange. When I´m connected to WiFi the download speed is good for about 5 minutes and then it drops to almost 0 so nothing loads anymore. Same thing happens with 4G. To fix this I either have to turn on WiFi or turn it off. After that it works just fine for another 5 minutes. Is the hardware defective or is this some software problem which happens to other people too?
