920 here. Check my other thread about complaints. But no forze for sure. I did failed to reconnect to internet even though it says I have LTE. I had to reboot to get my internet back. Didn't complaint that on my thread because I am still evaluating it.
BTW, I removed all AT&T apps except the one cheching data usage. And I removed Nokia Map, Nokia Drive, and most of OEM crap. You can try that first.
