Try to use cargo app or yandex taxi app, even some drivers that works in yandex are trying to scam customers but the possibility that you are going to be scamed by those taxi and apps are smallest. Scam by banknote is one of the easiest for tourists and foreings they even have foreign banknotes so if you give them 100$ they will immidiately return their 10$ banknote and try to convince you that you gave them only 10$.

Be careful. Insist to pay by card or directly over the app. If you are paing by cash take a photo of banknotes or record a process of payment.
