I want to share an experience related to a device xiomi mi4i. My friend using this device since 2016 and it looks good in hands good colors but they face a lot of issue in their device the first thing is the device doesn't have micro sd slot and it has a only 16 gb of rom which is not sufficient.
The next thing most the apps can't work in their phone whenever he tries to install some apps in their device some apps didn't work properly. The next thing is heating issue his device heats very much with a normal usage and if the device heats so much then the hanging issue start in the device and it affects the functioning of the device.
The processor not works like a octa core processor this type of processor works really fast but in this device it fails to stand on my expectations.
