I have noticed that there are a few apps that are just unusable on the CAT S60. the Facebook app - though I could not get it to function correctly on the much more powerful Sony Z5 either, where it would just never update the wall. On the S60 though the app just does not work. Facebook works very well in the Android Chrome browser though. Deezer app: here it works very reluctantly, making it very close to unusable too. I am close to uninstalling it. Actually, it did not seem to work on the Sony Z5 either, which is why I cancelled my subscription to that service. On the laptop, Deezer works very well. Sadly they don't allow one to use the browser version in the phone, as Facebook does. Soundcloud: I also uninstalled that app as it was too slow. But many other apps work fine: I have no trouble with the YouTube app, WhatsApp works great, Facebook works fine inside of Chrome, I have listened to french radio stations without any trouble, Google Maps works very well, ... Are these apps just badly written? Is the CAT S60 processor, that is a middle range processor too slow? Will perhaps the next version of Android Nougat help?
