Infinix hot 2 which is the second version of the popular infinix hot was released last year, the device was launched with Google android one, you can read more about this here. Because of this, infinix hot is said to receive update for new android versions.
- Missing Sim contacts
- Missing data from internal memory.
If you are yet to receive yours, I will suggest you wait for sometimes or before upgrading make sure you do the following.
- Move all your files on your internal memory to SD card
- Remove your SIM card in other to avoid missing contacts or contacts without names
What I noticed after upgrading is that the phone lags alone and somethings very slow to response. I hope Google sends a fix soon, right now I am unable to save contacts to sim because the option is missing.
update 27/10/2016: According to a user on nairaland, which i also tried, go to your contacts app, click on the three dots then import & export then import your SIM contacts. the good thing about this is that now you know who you are calling the bad news is when you receive a call only numbers is showing.
Let me know in the comment box on fixes and issues you may have with the device.
