Screen goes black for a while when making a call

[PDas]

From yesterday,  whenever a call was made, the screen would go black, only the upper side (sim status, battery percentage, clock) and the lower side (back button, home) are active. And after 15-20 seconds the normal call interface appears on the screen.

If anybody has any solution of it, please let me know. Thank you.

@PDasI see you're using a third party theme. have you tried switching to one of preloaded themes, or even uninstalling the theme for a while, to see if the same thing happens?

Hi,

It has certain started from yesterday. And the theme I use from right after purchasing the phone 4 months ago. The theme is not making problem for sure. Is there any other solutions please let me know. Thanks

@PDas still, it wouldn't hurt to try. anyway, you should see if the same thing happens when you boot to safe mode.

Dear @najodleglejszy, it is not happening when it is in safe mode. But in regular mode it is happening. And after sometime when the normal call interface appears, then only the call is possible. 

Now pl suggest what do I do.

[najodleglejszy · Accepted solution]

@PDas since it doesn't persist in safe mode, it's caused by one of the apps you have installed, as all safe mode does is that it disables third party applications. the question now is which app is causing that. I'd strongly suggest temporarily uninstalling the custom theme you're using, as themes sometimes cause some weird bugs like that. if the problem doesn't disappear after that, then you'll probably just have to try uninstalling apps one by one, starting from the ones you updated or installed recently, until you find the one that causes the issue.

Extra tip:

When you see your apps, then tick the 3 dots in the upper right corner.

Then sort by date.

You will see the most recent installed apps.

Start deleting the last installed app and so on until your problem is over.

@najodleglejszy, thanks... for your support. And the issue is fixed after uninstalling almost all the 3rd party apps. Thanks a lot.
