Dont think flashing official firmware from there will void your warranty as its official.
Tried flashing the latest stock ROM, same temporary fix like wiping the cache, but after a few hours, goes back to normal. This is with no other apps installed, other than the speedtest app, which I installed after I first identified the problem, so its not an app.
Another thing I noticed is that it went away after I disabled the 5Ghz wifi connection on my router, but it came back. The I tried manual wifi channel instead of auto, same thing. Problem went away, and then came back.
If I change the wifi channel the problem goes away, and then comes back after a few hours.
It seems like wifi settings must have something to do wit it, but I can find a combination which cures it completely.
Any help would be greatly appreciated, this is starting to drive me bonkers
