Today we will talk about the display light problem of Android phones First I will tell you what is the display light problem of android phone and then I will tell you how to solve this problem.

To solve the display light problem, first you have to install a new display and check. If this problem is not solved after installing the new display, then I have discussed it below.

Android display light solution

If there is a display light problem in the mobile phone, it is necessary to check with a multimeter whether the power supply is going to the place where there is a display light section on the motherboard of the mobile phone.

If the input power supply does not reach the display light section properly, it needs to be fixed. And check the EN signal means control point

Follow the steps below to solve the display light problem of Android phone

• If the input supply in the display light section is correct then the boost coil needs to be changed from the display light section and then checked.
• If this problem is not solved even after changing the boost coil, then the rectifier has to be replaced
• Try changing the feedback register in the third step
• And lastly you try to change the display light driver IC

If this problem is not solved even after applying all the above steps, then I have created a universal method that you can solve the display light problem of any Android phone by looking at it.

I have discussed below what components you will need to create this light section and what their value will be.

To make this light section you will need a total of 6 components a light driver IC a boost coil a rectifier diode a register and two filter capacitors , display light section will be created with these 6 components

1. DISPLAY LIGHT DRIVER ICs (MP3202/IL6KC/IL60A/IL67N/IL6EN ) These ICs can be used in this display light section
2. LIGHT BOOST COIL 10uH
3. Rectifier diode MBR0520
4. Resistor 3Ω to 5Ω ohm
5. ONE INPUT SUPPLY FILTER CAPACITOR 4.7uF 5V ONE OUTPUT SUPPLY FILTER CAPACITOR 2.2uF 50v

Friends this method is completely testable I have used it myself before then I am sharing it with you it works 100%

I have shown this method here because many times we do not have the same digital microphone. Therefore, if you do not have the same microphone, then you can see this method and connect any digital microphone to any mobile phone. I would say to use a 3 pin digital microphone to do this method because it is very small and it sits very easily on any mobile phone. However, I have shown here a 3-pin digital microphone, a 4-pin digital microphone, a 5-pin digital microphone and a 6-pin digital microphone. And these 4 microphones are the most popular. Most of these digital crystal microphones are mobile phones.

Friends, I created this method myself and it is 100% effective, so I will do it exactly as I have shown here.

When using a digital microphone, we need to pin out 3 points from the digital microphone. 1. vdd- power supply v1.8 2. data digital signal audio point 3. Gnd ground negative point . Jumping these three points of a digital microphone will do the job

3pin digital mic use any digital mic support mobile phones

4pin digital mic use any digital mic support mobile phones

5pin digital mic use any digital mic support mobile phones

6pin digital mic use any digital mic support mobile phones

The microphones that are used on most mobile phones are the ones I showed you how to use here. I’ll give you more updates on using a new microphone here in the future Thank you.
