How to fix the android.error.acore issue?


Something may be wrong with the data in your contacts. Delete data and cache of it. 

Go to Settings > Applications >Contacts > Storage > Delete data and cache.


Very important  – Back up your contacts because you will loose every phone number. 


A simple way to save your contacts:

Go to Contacts > Settings > Export 

Select all your phone numbers and click Export.

A .vcf file will be saved in your files. You can use the .vcf file to restore all your data on any other devices too.

Some android phones do not have the export option so here is a simple alternative.

Go to Google Play Store and install Super Backup. Open it and allow permission. Now click on Contacts and select Back up all. This will also create and save a  .vcf file on your device. You also have the option to upload it to the cloud for future use.


After deleting the data turn off your phone for about 3-5 minutes, then restart it.


2.Restore the deleted system applications

Thanks to Android Data Extraction we can easily get back our disabled system applications.

Download the Data Extraction on your computer, install it, and run it.Connect the device to your PC with a USB cable.

Boot your phone in download mode. To enter download mode on most of the android phones you need to turn off your phone then press the Volume up and the power button at the same time and hold them for 5 seconds. 

If it is not working search in Google for “how to enter download mode – device model”.Select the second option. Select your phone model and click Confirm.

3.Update errors

If the acore pop-up comes from an updating not finished then roll back the update or ultimately  install an official version of Android. A guide will be here at Androidjar soon.

4.Factory reset 

This last option is not something we like but if we can’t fix the android.process.acore has stopped error we might be forced to go for a factory reset. I assume everyone knows how to reset an android device.

Click Settings, click the search box on top and simply write – Factory Reset.
