ONeAD is a refer and earnapplication when we can earn money by bringing friends to sign up whith our referral code and for this we get aome cash for each referral.OneAD claims that one can earn up to 2.5L per month by sharing their referral code.When I signed up on this application I get about 3 rupees per referral. I tell my friend's to download this application with my referral code and they will get money for it. They signed up and I get about 6 rupees estimated monthly income. After few days I get notification from Google Play Store to update OneAD. I updated it. Thinking that it will be going to more better. But, from that update OneAD become worse for mr. OneAD request Notification access of my phone. I granted permission. After that when I unlocked my phone I got a lot of notification and advertisement from OneAD. Due to which my phone gets down slower. Also I can't get enough battery Life. My friends also told me that they get lot of advertisement from OneAd, so they are going to uninstall this. I also uninstalled this app. But I don't see any improvement in my phone. Then I finally do a factory reset on my phone to get back it in a good condition. It worked fine for my phone. I get it's previous status as it was.So, friends this is not a worth application to earn money by putting your phone on risk. Better to avoid this application because it consumes more RAM, more Memory and More Battery of your phone by showing a large amount of useless advertisement.
