I have had my Galaxy S 4G (Fascinate on Telus) since last October. Love the phone even without dual core. Everything has always worked perfectly. No problems. I just picked up a Galaxy Tab 10.1 and again, no issues. Everything works perfectly. Last week, I tried to access the Samsung App store on my phone, and I got a window saying there was an update. I clicked OK, the window showed a green progress bar that ran up to 100% quickly, then showed the alternating green/black progress bar, but just exited. This was the start of my first headache with the Samsung Android products I have. I removed the battery and restarted but same result. I uninstalled all previous updates (to the Samsung App Store), but after one update it tried to update a second time...same result. I performed a factory reset and tried the Samsung App Store...same result. Setting>>applications>>Samsung Apps Notification Off ....same result. Setting>>applications>>Unknown Sources (Allow non-market apps) ON (Green Checkmark) ....same result. Samsung has washed their hands of me. They give up trying to help because they say everything that can be done has been done. I feel this may be an issue with the last app store update. Is anyone else with a Galaxy S 4G (Fascinate) having a problem getting into the Samsung App Store? They have told me to contact Telus, but I highly doubt they will be able to do anything since they don't control the Samsung App Store and its updates. Anyone have any ideas? Please, no "what do you need the Samsung App Store for" responses. I have already made use of it several times for things that were not available in the Android play store (or whatever the heck they're calling it now). If anyone has an idea I'd be happy to try it out. After the weekend I'm going to contact Telus once, then I'll try the Samsung help one more time. I'll factory restore the phone once more after that before, if no further help is available, demanding a replacement phone free of charge. If I'm the only one having this problem, then a factory restore should have fixed it. Since it didn't, I have to wonder if perhaps many people are having the same issue and either don't realize it or don't care because the Android store still works. All the rest of the phone functions perfectly. I doubt it's a phone defect since I think if it was there would be another symptom other than the Samsung Store not working.
