Never buy these phones!
Bought a umidigi F2 back in February, got it a month later... BUT since day one earpiece did not work on VoIP calls... After contacting customer service i didn't get any proper help and they offered to reimburse partly after i send the phone back (i did not). I kept using a headjack meanwhile... Last month the fingerprint sensor just died suddenly and the option in the settings too! A few days later the microphone gave up... Then ... It randomly stopped ringing at times and today it stopped connecting to the internet! I had to buy a new phone in less than a year! Never buy umidigi!
