Didn't know this, thank you very much for explanation. I really wonder how it will performed on android powered laptops

Well, after the latest update most of smartphones I have checked or saw on screeshots, have all same hashrate - 30H/s which give about 10 ETN coins per day. I don't really know chromebook specs, but I'm wondering too if those would get more hashpower than high end smartphones. Although they may be not compatible with Electroneum app, cause for example I can't install it on my Samsung Galaxy S2 Tablet.
Am also finding it strange why some good spec device are not compatible with the app? I think this is a flaws in the part of the mobile mining experience, it can only support one of my device, why make it compatible to some device and not compatible to other's? I thought follow up updates could have fix this discriminating error or some how the dev are aware and are working to fix it, but i guess am wrong!
Between balance has not reflected in my wallet till now, i don't know, but seem the network is really congested as it is.
