How to Fix Infinix Nougat 7 Problems & Hot 4

Infinix smartphones mid last year started creating buzz in Nigerian mobile market over products like Infinix Hot 4, Infinix Hot 4 Pro, Infinix Note, Infinix Note Pro, Infinix Zero 4 and Infinix Zero 4 Plus. They are great brands of smartphones if you ask me.

fix Infinix Hot 4 X557 and Hot 4 Pro X556 bugs

But lately last year, I began to listen to complains and buggy issues with Infinix Hot 4 Pro X556. It is normal for bugs in smartphone functionality when it happens only to the operating system.

But when you have issues with Infinix Wifi not working, fingerprint sensor not working and all that; it become a panic. Even calcare won’t fix except replacement.


This article has been extended to solve all Infinix Nougat Issues.

Below are some common Infinix Nougat Problems

  • Memory not accessible via PC or USB cable
  • Constant Rebooting
  • Phone gets too hot
  • Wi-Fi takes longer to connect
  • Call volume is sometimes low and unclear
  • Battery drains too fast
  • Phone takes up to 4 hours to charge complete
  • when receiving calls or sending calls, my infinix hot 4 screen goes blank and all functions seizes
  • OTG not working
  • Permission problem keeps saying screen overlay is turned on
  • Hotspot not working when it’s switched on. If I attempt to set it up from settings, it crashes.
  • Bluetooth switches on itself when I restart the phone.
  • Camera Isn’t working
  • Camera quality has reduced
  • Mobile data not working
  • Automatic screen rotation not working properly
  • Apps not responding
  • Constant System UI crashes
  • Recent apps not clearing

When you study the above well, you would understand that it is a whole lots of problem. To fix these Infinix Hot 4 pro problems, I have to categorize them according to similar fix method.

Fix Infinix Nougat 7 Problems, Hot 4 Pro X556 problems

Constant Rebooting

When your Infinix Hot 4 or its Pro reboots constantly, what you do is to make sure that you have updated your firmware to its latest version.

You may go to Settings and deactivate Sleep mode. Then clean

Screen Overlay is turned on

When permission keeps saying screen overlay is turned on; it is either that you have installed a battery saver, energy saver or screen filter. It is not basically a fault from Infinix.

If that is not the case, then follow this => Goto settings > Apps, tap on the settings icon and choose Draw over other apps. Now select recently installed apps one after the other and deselect the option to draw over other apps.

Internal Storage is not accessible via PC or USB cable

If your Infinix internal storage is not accessible via PC or USB cable, then it is either the driver is not correctly installed on your system or USB cable is charge only.

For the case of incorrectly installed driver, what you do is to update your ADB driver. You can do this either by installing PDANet, universal MTK driver or through Windows Device manager. Click here for PDANet or MTK universal driver. It is simple to install.

For Windows device manager, right click on This PC or My Computer as the may be and select Manage. On the dialog window, select Device Manager. Locate the USB driver marked unknown to find the correct match. You should know how to update Windows driver.

Battery drains too fast or takes longer to charge complete

If your battery drains too fast or takes longer to charge complete, it is either you change charger or discharge your battery manually. To discharge your battery, open the back cover. Remember that it is non-removable battery.

What you do now is to take off the clip holding the battery to the internal case. Leave it for about 2 minutes and put it back. Please, if you had no idea about this, meet a phone technician.

OTG does not work

if your OTG does not work, failed wifi and hotspot, Bluetooth not connecting or phone goes blank when making calls, phone crashes and tons of them – you simply update your firmware.

Camera Isn’t responding or Camera quality has reduced

If your Infinix Camera stops responding after update to Nougat, you can simply reset camera Setting to Default.

If it does not work, try to clear the Camera Cache. You can find this at Settings > Apps > ALL. 

For the case of Infinix Camera quality, it is either your build is yet to fix the camera quality issue. Always make sure to clear Cache as well as factory reset after updates. Try the above solution for camera not responding on this.

Mobile data not working

Simply reset Network settings. To do this, follow the below steps

  1. Go to Settings
  2. Backup & reset
  3. Network settings reset
  4. Tap Reset Settings

This will reset all your network settings including your saved wifi, wifi settings, bluetooth, data

Apps not Responding or System UI crashes or Apps has stopped unexpectedly

Firstly, clear

  1. Clear App preferences
  2. Clear entire App cache (Install Clean Master or Ccleaner)
  3. Remove Babel font, set font to Default
  4. If not work, Hard reset

Recent Apps not clearing

  1. Press and hold the recent apps button
  2. Tap on the lock key icon beside app to unlock
  3. Then clear apps

Firmware is an official manufacturers bugs fixes and new functionalities to particular devices. Connect to the internet and get updated.

Even if other method fail, update won’t let you down. Enjoy your Infinix Nougat Builds.

    1. Hello Thelma

      I’m sorry about these challenges. It is obvious that you updated to Infinix Nougat Beta version which is the cause of this.
      You have done almost everything you can as far as my knowledge can take me.

      You may try any of these
      1. Clear Play Store data through the App manager
      2. Re-install Facebook from Play Store.
      3. If it fails to re-install using Play store, then download Parallel Space and install Parallel space
      4. If it fails, Facebook Lite may not fail

      If your hot 4 is rooted, you can clear com.facebook folder inside /system/data/data/com…facebook

      If the above fails, you may try
      1. Wipe cache partition using recovery mode.
      2. Hard reset Infinix Hot 4
      I hope these solve the issue.

    1. Hi Dalphie

      I’m sorry about these frustrations. Since you have done all these things without resolving, I recommend that you change/flash your device firmware totally because it looks like it has been compromised so bad.

      To flash your hot 4, kindly take it to specialized phone technician…It may not cost you 2K.

  37. Any time I decide to play game or use the phone with many other apps …..the phone off and then on by it self…….and I am getting scared of always using it what do I do please ?

    1. Hi Ekpe, you may need to install Clean master. It will help to free memory to allow you use multiple apps.

      You could also clear cache using clean master to remove unusable files .

      Mind the number of apps you run. Most apps require lots of memory before they could run. This could set your device to restart because it couldn’t handle the request.

      We hope you find this useful

      1. I have done that before…..it still the same

          1. Yes or is there any other way please??

          2. To clean cache,

            1.Open Clean Master,
            2.Tap on JUNK FILES
            3. Tap on CLEAN JUNKS

            That’s all.

            Also try game boost option on Clean Master.

  38. My hot4 do reboot whenever I play game……I don’t understand its hangs den reboot by itself

    1. You might need to hard reset your Hot 4. It should work properly after hard reset

          1. Pls I have done just that…. Yet still the same thing

  39. I have already done the hard reset yet it still rebooting by itself whenever I ham using it

  57. I just bought an infinix hot 4 pro but anytime I have a call, it won’t pop up the incoming call interface and wunt even show any missed call, but meanwhile it will be ringing from the callers phone.
    I did a factory reset and it solved the issue partially. I mean it starts ringing and showing the incoming call interface but I noticed if someone calls me, it wud have ring for like 4 seconds from the caller phone before actually showing for incoming call on my phone.. But now my big headache is when someone try to flash me, my phone will not ring and also it won’t detect I have a missed call atall, meanwhile it wud have ring from the callers phone.
    This is really frustrating as I can’t even know when someone flashes me cos my phone won’t detect any missed call. My phone only pop up for incoming calls after it has ring like 4 sec from the callers phone
    I returned it bk to where I bought it and they reinstall another OS but it still the same. I am also surprised cos my phone came with Android 7.0 from factory.i don’t know if this is normal.
