To those that upgraded their Infinix Hot 2 Lollipop 5.1.1 OS to Marshmalow 6.1 and was having problem with the phone, like lagging and phone heat up, the problem has been fixed.

Update your OS with the new update that u see on your phone and this will automatically fix the issues with Marshmalow OS. I have just done that and i ve fall back in love once again with my Hot 2 which i almost hated for the lagging and slowness due to the initial upgrade.

Thanks to Android technical group.
