[Galaxy S 4 i9505 Original Android Development] tophee:
I have understood that the problems with the camera can probably not be resolved any time soon, but I am having a host of other issues with the stable2 release. I don't want to complain to the developers because I know they are doing their best, but I do want to mention this, hoping that it might help finding solutions. So here is a quick list of the problems that I am having with Stable2 on my i9505:

The biggest thing was a huge crash about two weeks ago. I have never experienced anything like it on any ROM. At first it looked like the usual camera freeze which crashes the camera app but nothing else. But then I was unable to kill the app. I was unable to move away from the frozen camera screen. I could not access the reboot menu through long pressing the power button. In fact, I was unable to do anything. I could not even force reboot the phone by holding the power button for 10-20 seconds. So I took out the battery in the usual quick fashion - out and right back in - but the phone would not start. Only when I took out the battery for 10 seconds or so before I put it back in was I able to boot the phone again. Luckily, this only happened once.

But the camera freeze happens on a daily basis. There seems to be a pattern that the camera works fine the first time I use it after a reboot but the second time it freezes (Though not always) and once it freezes no camera app will work ("Cannot connect to camera") before I reboot the phone. I am using "Snap Camera" and I am using it almost exclusively for videos.

As a result of the big freeze mentioned above, had to reconfigure several widgets which either completely disappeared from the home screen or were suddenly set back to their default settings. Also some apps seemed to be somehow reset or at least they thought they were because they started asking for permissions that they had long been granted (and which were still active when they asked for them again). And the Messaging app was the default texting app although I have been using a different app for years. But the longest lasting consequence of that crash is that my contacts had completely disappeared from my phone. I am syncing all my contacts with an Exchange Server, so they were still on the server but I could not access them on the phone (except in my email app ("Nine"). At first, when I ticked the respective box in the default Contacts app under "Contacts to display", nothing happens. The same was the case in the "Simpler Contacts" app. Today I did a wipe of the Dalvic cache but to no avail.

I have a huge battery (5200 mAh) which usually lasts me way longer than a day. But with Stable2 I am sometimes (like today) running out of battery already in the late afternoon.

When I was recently travelling in a remote area with little or no coverage, I put the phone into flight mode to save battery. The battery saving worked but after a day or so the time was off by several hours (it was running ahead of time). Once it connected back to the GSM network, the time was adjusted automatically to the correct time.

My travel in the remote area was divided into two parts of several days and between those two parts, I had full coverage for an hour or so. I am using the app "Moves" which tracks my location also while it is offline. What is very strange is that it did so only during the first period and stopped tracking as soon as I had that 1 hour of internet connection and did not resume the tracking until it was back online. I first thought that this was a bug in the app, but when I checked my google location history, it showed the same pattern. I'm assuming that the phone simply did not deliver any GPS coordinates any more, even though location was turned on and set to high accuracy. So it looks to me as if there is some bug that stops GPS positioning under certain conditions... I have now set the STweaks GPS region, but wont be able to test whether that fixes it as I wont be out in the wild any time soon again. But even in theory I can't find a coherent explanation why the GPS region would have anything to do with this, since GPS worked fine at first.

While the lag is not as bad or as frequent as in stable1, I still have some extreme lag from time to time. I am using the app "PowerLine" which displays the CPU usage as a line at the bottom end of the screen and when the lag occurs, I am seeing very high CPU usage even though there is absolutely no reason why there should be high usage at that moment.

This one is a bit less concrete, but I mention it anyway: I seem to have some problem with WiFi internet connections. Sometimes a webpage just wont load or takes ages to load despite the wifi connection being on full bars. According to the network traffic displayed in the status bar, there is a bit of traffic happening, but very little. Most of the time, the webpage will load after 1-5 retries without the WiFi icon disappearing, but sometimes the wifi disconnects and reconnects again immediately before the internet connection will work again.

Any suggestions?
