No matter what mobile phone, you cannot add text on the screen. Signatures can only be added on the lock screen. Redmi note 5 is also not included. Disadvantages:

1: Serious heat generation

Especially when making calls on the train or using data to surf the Internet

2: Occasionally crashes

Maybe it’s a common problem with Android

3: The resolution is slightly lower

There is a slight graininess

4: The battery is not very durable

I am currently using 4.12

Basically flush once a day

A mobile power supply or backup battery is still necessary

5: The front camera is not very satisfactory
