With this button, you can quickly turn on data transfer on your Android device. If you do not have such a button, then you can enable data transfer through the settings.
Method number 2. Turn on data transfer through Android settings.
If necessary, you can enable data transfer through the Android settings. To do this, you need to open the settings and go to the "Other networks" section.

After you have opened the "Other networks" section, you need to go to the " Mobile networks».
In the Mobile networks section, you can enable or disable two features: Mobile data and Data roaming.
The Mobile Data function is responsible for data transmission in all cases, while the Data Roaming function is responsible for data roaming.

With the growing popularity of iPhones, the number of complaints about the quality of the recording properties of an expensive gadget is growing. The manufacturer is far from always to blame, usually the microphone does not work on the iphone 7 plus due to dirt and dust that accumulates on the mesh as a result of careless operation by the user. 
On iPhones, starting with models 4 and 4S, they put several devices. This was done for the comfort of the user, the devices acquired active noise reduction systems. Now it has become possible to talk without problems in a crowded or noisy place. A system of two recording devices intercepted the noise, processed it, amplifying the user's voice, and transmitted the sound to the speaker of the device. Thus greatly reducing the percentage of third-party noise. But you have to pay for comfort, with the increase in the number of mini recording devices in the iPhone, the number of user complaints began to grow that the microphone does not work in the iphone 5.

We start recording, we say something into the phone, there is no need to read the volume of War and Peace, three seconds is enough. Now we turn on playback, if the voice is heard, then the recording device is working in the desired mode.
- To test the upper microphone (to be near the iSight camera), you need to open the "Camera" and switch to the "Video" mode, turn on the recording, again, 3-4 seconds will be enough. Plays video, if there is no sound or it is very muffled, then the upper microphone is not working.

Take care of your expensive equipment!
We continue our stories about the problems that may arise during operation with the iPhone and iPad. And today we will talk about one of the most common types of breakdowns in the iPhone 4 and iPhone 4S, namely sound problems.
First, I'll tell you how it all works. Let's start with . Figuratively, the audio path in this iPhone models consists of a microphone (actually there are two), a voice speaker (it is from it that you hear the voice of the interlocutor when you put the iPhone to your ear during a call), a speakerphone, an audio mixer and an audio codec.
A microphone near the headphone audio output, which is used for noise reduction and for a voice recorder.
There are two microphones in the iPhone 4. One - the main one, is located at the bottom of the case, it picks up the sound during a conversation. The second is auxiliary, located in the upper part of the case and serves for noise reduction and as a separate microphone, which the recorder uses when recording sound.
The microphone used to transmit your voice to the other party.
Audio codec is a chip Cirrus Logic 338S0589. The chip is a hardware audio decoder. For example, when you listen to music on your iPhone, this chip converts the sequence of ones and zeros that make up a digital file into analog signal, which is then output to the voice speaker, loudspeaker or headphones.
The iPhone 4 uses a Cirrus Logic 338S0589 chip for sound processing.Illustration taken from ifixit.com.
An audio mixer is, in essence, a switching device that is responsible for communicating an audio codec with voice and loudspeaker speakers, microphones and headphones (10C0124A0696). And when one of the above fails, the problems begin.

So, what are the symptoms of iPhone breakdowns and what do they tell us?
Let's start with the disappearance of the volume level scale. For example, one day you press the volume buttons, the familiar speaker icon appears in the middle of the screen, but there is no volume scale below it. Such symptoms may indicate a failure of the dock connector cable. There is a loudspeaker on it, and because of such a breakdown, the audio mixer does not “see” it. Replacing this part will cost around 300-350 UAH.
Or it may indicate the failure of the audio mixer. It seems to be like the sound in the phone and is processed, but there is nowhere to output it. By the way, in such situations, this scale appears after connecting the headphones. If everything is fine with them and the scale is visible, then the problem is most likely in the dock connector cable. The cost to restore the audio mixer will be within 800 UAH.
If the iPhone 4 becomes completely numb, then this most likely indicates the premature death of the audio codec. In such cases, you will not even be able to start playing music in the Music.app application. And this is not surprising, because the device will simply have “nothing” to reproduce it. Replacing the audio codec will cost 600 UAH.
The failure of the audio mixer is accompanied by the “falling off” of one of the above devices for outputting or receiving sound: speakers, headphones (headset) or microphone. For example, you may not be heard by the interlocutor, or you may not hear him in the voice speaker, but only when you switch to the speakerphone. Or, instead of the interlocutor's voice, there will be some crackling in the voice dynamics. It is also possible that your interlocutor will not hear you during a conversation, and the recorder will wonderfully record the sound. Let me remind you that this situation is possible due to the fact that different microphones are used for the conversation and for the operation of the recorder.
And finally, sound problems can occur due to the failure of the speaker, microphones or headset (headphone) jack. All these breakdowns, as a rule, are covered by a breakdown in the audio codec, and it is very difficult to identify the real cause in the field. Replacing all of the above peripherals will cost from 200 to 400 UAH.
Now briefly about the reasons for the failure of microcircuits
There are only two of them. This is usually a factory defect or mechanical damage. The microcircuit fails and fails and is no longer able to perform its function, or the microcircuit is detached from the phone board due to mechanical impact (shock, fall). The most common cause is mechanical damage.
All of the above cases are not fatal. The non-working microcircuit is replaced, and the torn one is re-soldered into place. All of the above is fully true for the iPhone 4S, with the only difference being that it lacks an audio mixer. Its functions are performed by an audio codec labeled Cirrus Logic 338S0987 (Apple 338S0987 B0FL1129 SGP).
All of the above damage this moment are repaired unless the problem is due to a crack in the main board. Damage like me already
Important! If you are not heard when you call, it is a problem with the microphone. If you can't hear it, it's a speaker problem. The iPhone since the 4th generation uses 2 microphones. One of them (lower microphone) is located at the bottom end next to the charging / sync connector. The second (top microphone) is on top next to the headphone jack (iPhone 4/4S) or between the camera and flash (iPhone 5/5S/6). Finding out which of them does not work is very simple. It is enough to check the sound recording in the voice recorder application and in the camera application. (when recording video, the upper microphone is used, and the lower microphone is used in the recorder)
Sound problems on iPhone 7
One of the most common iPhone 7 faults is the Audio Codec. The signs are as follows: when you call, you can’t hear the interlocutor, the voice recorder does not record, and the camera freezes when recording video. If these three problems appeared on your iPhone at the same time - You need to repair the Audio codec.When talking, I can not hear or hear poorly.
If, when talking on the iPhone, you hear the interlocutor, but he does not hear you, this is most likely due to the incorrect operation of the microphone, which is located below. It can be clogged with dust, or simply fail. Therefore, you can try to clean the grid, which is located next to the charging connector. If that doesn't work, you probably need to change the part. It also often happens that when talking, you yourself close the microphone with the hand that holds the iPhone when talking. In this case, the interlocutor may not hear you well. To confirm that the microphone is not working, just open the voice recorder application and try to record sound.iPhone microphone only works on speakerphone.
This is a consequence of the fact that the lower microphone does not work and the upper one works. Try to follow the recommendations described in the previous paragraph.Audio is not recorded when recording video on iPhone.
If the sound is not recorded when recording a video, this means that the upper microphone is not working. In this case, you need to check if the lower microphone and speakers are working. As practice shows, in 90% of cases the microphone needs to be changed, but before that it is necessary to check whether it is closed with a cover or clogged with dust / dirt. To confirm that the upper microphone is not working, it is enough to turn on the speakerphone when making a call. If the interlocutor does not hear you when you are talking on the speakerphone, this confirms that the upper microphone is not working, since it is he who is used for speakerphone.This manual is also intended for iPhone 6 and 6S
