Can't figure out why I'm not receiving any emails anymore. Yesterday I was trying a few different applications by installing them like phone boosting security clean junk files to make my phone go faster antivirus memory and few others. Kept telling me that my memory is full my junk files is full that I had viruses on my phone. Think I made things worse. Just uninstalled all of them
Did you change the password of the email being used? Also, can you check Settings > Accounts > tap on the email account > Check if it is synced.
