Okay, so I'm new to these forums. But anyway, I've had my Verizon HTC One since release day, and I've had no problems with it, until recently. A few days ago, I noticed a lot of RAM being used up, so I started force closing apps, and trying to clear out the memory. No matter what I did, nothing seemed to work. So, I decided to restart my phone. When it came back on, the Sense weather clock had disappeared from my homescreen, so I went into the widgets to try and add it again, except that all my HTC clock widgets had disappeared. I thought "Okay, whatever. I can live without a clock on my homescreen." It wasn't a big deal. But then today, I installed the OTA update, and after going into my apps, I noticed that the clock app has disappeared entirely. I thought maybe I could just tap the clock in the app drawer to open it. Nope. It just says "App isn't installed". I went into the settings, and the clock app, as well as the weather clock widget, are still installed on my phone, but it's just acting like they're not there. I use the clock app for my alarm in the morning, and I know I can install a third party app from the Play Store, but I'd really like to know if anyone knows what's going on here, and if there's anything I can do to fix it.
