Blank screen during call fix

In this post I will be showing you different ways of fixing blank screen during call. I have seen many users facing this issue from last 4-5 years. I previously made 2 videos on the topic explaining how to fix the issue on my youtube channel youtube.com/encryptedguy. The problem is with the proximity sensor of the phone. This post will be the final verdict on blank screen during call fix.

There are 4 methods that I know that will fix the issue


  1. Checking if the screen protector is blocking the sensor
  2. Using Xposed module Sensor Disabler
  3. Using a moded phone.apk
  4. Physically removing / replacing proximity sensor (Haven’t tried it need your feedback)

 

The first one is the basic test that everyone should perform before going forward. Remove your screen protector and check if the problem fades away.

The later two is for users with root access. We need to play around with system to make this wok

I have made a video for both 2 & 3 if you don’t like reading you can watch the video to fix your problem.

Fixing using Xposed module :

 

Fixing using moded phone.apk :

 

Xposed method :

To use this method you need to install xposed and you should have root access.

After that you need to install a module called sensor disabler. Basically this module manipulates the sensor values so when system tries to read the sensor values the fake values are interpreted.

After installing sensor disabler you need to reboot your phone and run the app. In the app select proximity sensor and increase the distance to max.

Doing this will fix the problem of blank screen during call.

 

Moded phone.apk :

This method is little bit tricky you might need help from the developer of your phone.

You need to contact the developer and ask him to modify the phone.apk in such a way that it ignores the proximity sensor value.

To request this you need to go to https://forum.xda-developers.com/ select your device, select proper section and post your request there.

The final method is untested and should be tested only if you cannot live with this issue. Better ask a local mobile repair shop to perform this operation and if its successful let me know in the comment section of this blog

Creating first IoT project using ESP32-Node MCU

There has been a lot of development in the field of ioT and smart homes. We live in a era where most of our devices are connected to the internet. Raspberry Pi was launched in 2012 and with it there was a rise in several IoT Smart home applications. But the problem was that raspberry pi was a bit costly. Here in India it was available for around 3000 to 4000 rupees. We had Arduino uno before but it lacked Wi-Fi and adding external wifi module was a headache. But in 2015 a new device surfaced in the market with built in wifi. It was the node mcu. It was not as powerful as raspberry pi and it didn’t even run linux os but it was powerful enough to compute and control other devices. It was the perfect cheap alternative to develop iot projects. Later ESP32 was developed with more features and processing power. That’s enough history now let me explain how I managed to develop a smart home project. The goal : We should be able to control the lights using wifi. The Idea : ESP32 / Node...

  Aim : To understand buffer overflow and exploit a c code Things you will need : VM software(Virtual Box / VM Ware) Kali linux 32 bit Procedure : Let me break the procedure for your better understanding (Watch video linked to this tutorial for better understanding): 1.        Write / Copy C program 2.        Compile the program 3.        Execute the program 4.        Testing the program 5.        Disassemble the program 6.        Hack the program Buffer overflow is an anomaly that occurs when software writing data to a buffer overflows the buffer’s capacity, resulting in adjacent memory locations being overwritten. In other words, too much information is being passed into a container that does not have enough space, and that information ends up replacing data in adjacent c...
