I have been facing some issues in my mi2 for sometime now and I just wanted to know if other people are facing them too and if they found any solution. 1- Wifi Hot Spot does not work. It used to work before update to V5. It just says 'turning wifi on' and thats it. 2- Receving and making calls has glitches. People sometimes have to call me two or three times to get connected. Their previous calls show up as missed calls. Sometimes when I call someone it just gives a tone and it says call not completed. I have to try two or three times to get it to work. I have all my contacts saved in international format like '+ countrycode area code phone number'. Can that cause a problem? 3- Getting OTG to work has been the most frustating experience with mi2 for me. It is very random. I have to twist cable, remove/connect several times for it to even recognize. Apart from all this, I still really like this phone.
