So, during last three days I've had weird hiccups with my Samsung Galaxy S3, which I've had for almost 3 years by now. On random occasions, my phone's internet signal seems to randomly cut off (as the connection bar is replaced with error cirle icon, which would not be offbeat by itself probably, but sometimes when this happens, my phone's screen starts flickering like malfunctioning TV or computer monitor. I'm not completely sure if these two issues are connected, since the connection issues have been happening without screen flickering. When these issues have occured together however, they've occasionally caused my phone to freeze and restart or I've had to restart it manually, and on one occasion has caused it to fall into restart cycle, with new restart right after the screen flickers again when it gets to the screen where I'd enter my pin code.
Today I noticed that when the screen flickering starts, Avast Mobile Security gives a notification of too many processes running on the same time on my phone. When I've tapped on the notification and let it close all those processes, some of them have been normal processes running constantly, but some of those processes are kind of which should not be running by themselves, like photo gallery, camera, alarm clock etc. which don't appear to be visible when I try to check my phone's "running processes" menu.
I've been talking about these issues to some, and I've heard suspicion for possible gremlin in my phone, it feels little weird since I haven't visited any random websites with my phone and only visited offical websites, nor ever installed any applications, and neither Malwarebytes Mobile or AMS haven't detected anything. I've also had some occasional lags and freezes here and there with my phone all over the year, so I've personally had thoughts about my phone simply being getting old. Another interesting thing is that all of this doesn't seem to occur when my pohne just sits idling, and only starts when I browse internet with mobile Firefox. The time when all this randomly occurs seems to be whenever I use my phone at work 10.00 - 14.00, but after that when experimentally using it at home, it doesn't seem to do anything. All notecable I've done during the last week has been installing bunch of application updates, which I remember doing on the same day as all these hiccups started.
So, this is all rather problematic. Could it be my phone would be messing with itself or something else?
