Ever since the last OTA update I have been fighting frequent (5-6 times a day) system crashes. This will happen in a any app, or when I am using the dialer. It happens most frequently in Chrome, but I think that's because that is my most used program. When it crashes the screen goes black and comes back up with the main screen, Bluetooth disconnects and reconnects and the main screen has to reload. It's not a reboot just a crash and recover. I took it to Best Buy and had them reflash the ROM, clear the cache, and take the phone back to factory. The OTA downloaded and installed. I'm completely stock, no weird apps, mostly just business use. Crashes in banking app, holiday inn app, strava, garmin, dialer, chrome, no pattern or reason. Anyone have any ideas or suggestions? Could the SD or SIM card be causing this?
