I have a strange problem on my iPhone 7 plus a1661 whenever I run Speedtest on it for my local wifi at first attempt I get accurate ping and speed but on second third fourth attempts it gives me very high ping and unstable speed what could be the issue? I had reset my network settings but still not solved

I have conducted same test at my android phone but everything shows up accurately even better speeds on my cheap android phone ! Not to mention I have no noticeable speed problem on my iPhone 7 plus while browsing or using facebook

Here is the screenshot of unstable readings on my iPhone 7 plus

Several things can affect signal and cause fluctuations. If you really want an accurate wifi speed test, do it on your computer. It's much more accurate than a phone. Are all the server locations the same?

after trying different methods i came to know that is the ios speed test app which is not providing accurate readings after few tries......i tried ookla's speedtest web browser test from safari on iphone 7 plus and it is giving accurate readings...also tried same app on my iphn 6s ....same issue is happening there too... so it is definitely speed test app..for ios.....
