I have read some technology-heavy recessions here. No problem for people with relevant expertise and instruments. I use this device for music, audiobooks, WhatsApp, Skype, Calendar and of course I also telephone thereby. The sound is clear and good for my poor ears. The display is amazing. (Positive) Android version is a 4.1 ... Wiko does not like Android updates. System updates are easy and timely. Initially, it was not possible should get an online connection for me. (About Sim, Wifi ran) Solution: SimKartensteckplatz exchanged in the phone. Not. My old Samsung with new simcard (IFI) equipped. Tried Settings, ran! Card back into Wiko. Internet via Sim worked! All this with the friendly, patient accompaniment of 1ยง1 Hotline. AMAZING WHAT THEY SAY FOR can buy 131.- Euros.
