[Xperia Z5 Q&A, Help & Troubleshooting] rfgamaral:
I did not have time before but here are my reasons for having seconds thoughts on whether I should get this phone or not:

CAMERA: It's a good camera, much better than my current M7 and similar to iPhone 6S, but it still shows more noise than it should and feels like a watercolor painting. Also, look at this picture, I'm not expecting it to look like the 808 pureview, but the Z3 compact looks much better. On my next phone, whatever that is, I'd really like it to have a good picture quality. Judging that last picture, the Z3 compact is acceptable for me, but the Z5 one it's just horrible. Maybe this was taken with an older firmware and it's better now and maybe it will get better on the future but I don't know any of that and can't make decisions based on what may or may not happen.

The low-light capability also bothers me a lot because the M7 is the same way (although one of it's selling points was just that, I guess I was mistaken) and I wanted something better. I do know that the Z5 camera has other things going on for it, like excellent OIS for video and "an incredibly fast and accurate 0.03-second autofocus", that's awesome. But on the other hand, the app takes a while to load as someone stated above and reacts kinda sluggish (from what I've read). I know every phone will have small faults like those but they still weight a little on my decision.

ROOT/BOOTLOADER: Unlocking the bootloader and/or rooting it breaks stuff like X-Reality, Bravia Engine and Advanced Camera features. This was not a very good decision on Sony's part and I don't expect them to revert their position on this. As a guy who likes to tinker with his phone a lot, this is something that really bothers me. Yes, I'm completely aware that there's currently a work around for this but this problem should have never existed in the first place. Yeah, I know, other phones may have similar or worse problems, but this is something that bothers me. Maybe this "fear" is unjustified. Have you guys unlocked your bootloader and rooted your phone. Did you restore the DRM thingy? Is everything working as expected like X-Reality and stuff like that?

ROM/SOFTWARE/FIRMWARE:

This post bothered me because I feel the same way, a phone like this should not have any kind of slow downs, it's a powerful phone and there's simply no reason to be sluggish or laggy. Maybe it will get better with MM update or maybe it won't, we can't know that for sure. That's why I was looking to get an AOSP build into this, instead of Sony's custom version. From the few minutes I've played with this phone at a store, I do like the fact that Sony made minimal changes to the UI, that's really a plus. But I'd prefer if it was completely stock but with all hardware improvements (i.e. X-Reality and camera). And to clarify, it doesn't really matter to me if this is running Lollipop or Marshmallow (although one always prefers the latest and greatest) as long as the software runs smoothly and without any annoying bugs.

OVERHEATING: This phone uses the Snapdragon 810 chip which had a lot of overheating issues. Yes, Sony and almost everyone else seems to state that this issue has been fixed on the Z5 by under clocking the CPU (without a big impact on performance). However, I've read a few comments still stating that the phone can till get extremely hot and I come from the M7 which has a completely different and older chip but it also gets extremely hot. I'm worried that the Z5 gets hot enough and making it uncomfortable to use and everyone has a different sensibility so it might not be too hot for some, but hot for others. I don't game much (on the phone) and this issue is probably most visible with gaming but I've read reports that updating apps (and maybe other actions) can the phone a little bit too hot. For instance, my M7 gets hot while browsing the web with Chrome and that's one thing I do a lot with my phone. This is a huge concern for me as I'm kinda sensitive to heat.

To sum it all up...

The camera picture quality could be better. Maybe it's a software problem that can be fixed. I could deal with this since it's actually a lot better than my current M7.

I like to tinker with my phone as such I need root and I need Xposed.In the Z5's particular case, we have the DRM issues. Can someone really confirm me that this is no longer an issue? Can we unlock the bootloader, root the phone, install Xposed and still have all the hardware and Sony enhancements? Cause if not, that's reason enough for me to not buy this phone.

It seems that the ROM could be better (as stated by the [MENTION=5122995]Phazonclash[/MENTION]), maybe it will get better with MM update. I'd prefer I could get an AOSP build into this phone and maybe this will be possible in the future. I can still accept this phone as-is because Sony's ROM has minimal impact UI wise, I just hope that the software is not as bad as stated above.

As for the over heating issues, if they are not as bad as my M7, I can probably handle it and accept the phone as-is just fine. If it's too hot for me, maybe this phone is not for me.

This is my opinion based on what I've read on these forums, maybe there are some misconceptions and misinformation and I hope you guys can clarify me on my doubts. I'm not trying to bash anyone's opinions or their decisions on buying this phone, I'm just trying to understand the pros and cons of this phone from my point of view, for my needs and requirements.

I apologize if any of you felt like I insulted you or bashed you in some way. Although I don't think I ever did that, I apologize if you felt that way.
