Today I will give you a Samsung phone review. Samsung has a new foldable smartphone. Let's give the smartphone's audio system a full review.

First don't look at his audio, just open the appearance of this phone, see its folding screen is ok, feel good, folding screen is very convenient to use, the weight is relatively heavy, it would be better to make a little lighter. Folding screens requires a higher level of technology, so Samsung is investing heavily in research and development. When you look at the screen from the side, the overall screen is very smooth, and you really can't tell it's a folding screen. It's very convenient to watch movies on screen, and the picture quality is very realistic. When folded open, the interface looks a bit like a computer.

Besides, the stylus can be operated and recorded on the mobile phone at any time. The use of the smart pen is just like the ordinary pen, smooth and natural, very accurate, and it can write and draw freely on the screen.

It's a waterproof foldable smartphone, so you don't have to worry about burning your phone if you drop it in the water.

You can also split the screen to operate, you can take notes, watch videos, chat, etc. It's as easy to operate as it is on a computer.

In terms of hardware, the audio control unit he used is a very reliable part that has been used in the market for many years.

. Samsung's smartphone-folding lock uses online music, which can also be played. Radio music online, and you can play local music.

The phone is Android-based and has a built-in music player that doesn't work well with the foldable screen. The space of the interface is not fully utilized, but it is still easy to find the sections of online music, online radio and local music you need.

However, local playback mainly supports some specific audio formats, many audio formats are not available.

The following is a simple evaluation of the external device of this mobile phone. This time, I will evaluate the audio device of UC 2.0 and test the project of Bluetooth decoding support. First, when the device is plugged in, it automatically powers up and recognizes that the default output of the system is switched to the device. However, this device does not fully automatically switch the sampling rate, and you will output the minimum frequency when the sampling rate is less than the frequency. If broadcast frequency sampling rate does not meet the requirements of the machine will appear the sound quality is not very good, if you want to be able to get a better sound quality, you can use other APP swimming to playing the local music, so his quality will be improved greatly, but online program is not enough this kind of method to solve.

After testing the frequency response curve of the LDAC of this foldable phone, it is found that the intermodulation distortion is very serious.

This Samsung foldable phone supports Bluetooth 5.2, SBC/ACC/APTX/LDAC, and Samsung's own encoder. But he doesn't support some of the most popular codes on the market. This is strange because it is very inconvenient for consumers. Perhaps because Samsung wants to use its own independent codec to avoid some patent fees for use. But that creates consumers. There are very few headphones that work with the phone, and only Samsung's own headphones work with it. In order to use better earphones, we tried to connect traditional earphones with a 3.5mm headphone jack converter, but it didn't work after testing. You can't do this part of the test. Because our hands all transfer simulation line does not support, after insert the phone will display does not support the USB device is connected, this way let consumer very antipathy, if not through their special headphones, can't get a good sound quality, if use the wireless headset to operation, consumers can choose the choice of bluetooth headset is also very small. I feel that the design of this product is not in the position of consumers, and the price of the phone is nearly 2000 DOLLARS, which is really disappointing.
