Today, I want to talk about Vivo Y91 phone.I am using this phone for one year and I experienced that this is the modern phone.One good feature is that it is inbuilt so its battery cannot be griefed.A bad feature is the virus notifications by hacker on Google Chrome.I received weird notification from Chrome, then father said it is virus and I immediately turned on the antivirus.But another good feature is system update.Yes, you can have two types of systems together on this single phone.And, its Ocean Blue colour catches the eye.The best part is that it has 23-24 GB storage.Best part is cost.The same model of other company costs 30, 000 rupees plus.While, this only 7, 000 rupees.Buy and enjoy!
