The main problem in this way is that when it is connected to the computer and activated, the data is no longer available on the smartphone until the mass storage of the computer is disconnected, which can also cause some failure in the applications when trying to access it. In the event that the device has an external memory card, it is also mounted independently as another storage device. In this mode, the device simply connects as a USB memory or a conventional external hard drive, so that we can work with this storage space without any problem. This mode is undoubtedly one of the most useful, compatible and easy to use. This mode is basically recommended only if the user wants to transfer photos easily as it allows us to transfer photos from the device to the computer without the need to use any additional software or tool.

While in PTP (Picture Transfer Protocol) mode, the smartphone simply behaves like a photo camera without MTP support. Generally, when we connect the cameras the computer simply offers support PTP and MTP at the same time. This type of connection is the least used by Android users, as when users select this method, the Android device is displayed on the computer as a camera. PTP (Picture Transfer Protocol) on Android This protocol can also generate some problems of incompatibility in other operating systems like MacOS, as it does in Linux. Moreover, this protocol has some drawbacks, as it is more unstable than mass storage and much less compatible, for example with Linux operating systems, because MTP depends on specific and proprietary drivers to operate. However, the fact is that the speed of this protocol is quite lower than the speed offered by mass storage protocol, although it also depends on the device that we have connected.

And below we have mentioned the steps that we usually follow when we connect our Android device to the computer and here they are. Basically, in this method, the computer has no control over the storage device at any time but behaves in a similar way as a client-server connection does.
