Several issues started regularly happening a few days after I upgraded to the G3. First, chrome keeps crashing spontaneously, even when running in the background. Other apps don't crash seem to be reloading or briefly timing out for no reason--for example, kindle pages will go blank and reload every minute or so, and the same even happens when I go to the home screen sometimes. Lastly, the Google Play store rarely connects and either displays a blank page or the loading circle. I was relatively sure this was the work of a virus, but I did a factory reset and the problems persist. Could a virus have survived the reset (or could I have reintroduced it moving data back to my phone)? If so what else can I do? First post in this forum, help for this newbie would be much appreciated.
