I own this smartphone for 3 months. No bugs to report. Instead, many are SHIFT with MIUI France who do an outstanding job. We are 1,000 miles from Wiko that tends to take its customers for cash cows ... To be honest, I've owned a 3G iPhone 4S and then I finished by wiko cink Peax 1 and 2. Wiko is standout: their phones, whatever the model, are low-end and only bring you problems. I changed the Peax 1 by 2 after 6 months and 2 after 6 months ... Xiaomi has not ashamed to face apple. Their phones are fine finishes: screen retina, protective gorilla glass and touch worthy of Apple. Please be aware that Xiaomi phones are mounted with FOXCONN, the Chinese manufacturer of iPhones! In China, Apple has been dethroned by Xiaomi unharmed. No, frankly, Xiaomi worth a visit and MIUI interface is a marvel!
