[Xperia Z3 Q&A, Help & Troubleshooting] RCJ89:
For me Note 4 has

1) faster charging an i am not uncluding the fast charge mode either, it also has better battery not by alot maybe by 1 and half hours but considering it is pushing a 2K screen.

2) the note 4 is louder in calls (also better call quality and reception), loud speaker (Z3 sounds better though) and in headphones (better audio quality too).

3) Note 4 also has caller readout and also blocking mode and more call settings like better call equalizer and additional loudness volume and other neat little features like when you press the volume button from the home screen your able to turn up ringtone, media, notification and system sounds independently of each other where as on the z3 you have to go into settings, quick toggle notifications are also a bit better as they are right there when you pull the menu down whereas on the z3 you have to click on qucik settings tab i mean things like these is why I like Samsung phones despite touchwiz being laggy at times. Also on the text message keyboard the number buttons are at the top so you dont have to click the number button to bring numbers up. It just has more features and I am not talking about those useless things like eye scrolling and air view and the motion stuff.

4) Note 4 is better for playing games plus the larger screen gives you more space I guess due to being more powerful and better GPU, it doesn't skip a beat nor does it get hot when I play asphalt 8 for a long time, battery also drains less during gaming.

5) Note 4 feels more solid but I guess thats due to the additional weight but both phones look and feel great to hold, Z3 is easier to use due to smaller dimensions

6) Note 4 has better screen but Z3s screen is alot brighter

7) Note 4 has better camera/video recording and video sound

8) Multi tasking features and S pen ofcourse

Call me mad but despite all of this the Z3 is my main phone reasons being

Yes the note 4 does majority of things better but the Z3 still has

1) A very good camera/video recording and video sound and focuses fast

2) not as loud as the note 4 but DSEE HX really does make a difference and especially if you use the MDR-NC31EMs and sound quality is still . I don't find the Z3 as low in volume as the Z2, Z1, Z, T & S before it however Sony still could improve on the volume.

3) Call Quality and reception on the Z3 are still more than good enough

4) Battery life is excellent

some things that maybe some people do not know about or care about but I do and is a thing I have always been annoyed with samsung phones for a long time

5) you can't send messages longer than 3 pages without it turning into a MMS (sony and HTC allow you atleast 10 pages) and as someone who texts alot this is really annoying. Another thing is if you want to forward messages you can only do so to 10 people at a time (say you want to send a invite to a party or merry christmas or happy new year to people in your contacts)

6) if your in a phone call and someone sends you a video via whats app, you cannot watch the video until you end the phone call (Sony and HTC allow you to watch the video)

7) I understand this really wont apply to some people but you can listen to music and record video when your in a phone call (You can also do this on HTC phones) the music one doesn't bother me really but sometimes when I am on the phone and I see something sometimes I might want to record it and with a samsung phone u have to hang the call up first where on a htc or sony phone u can just tell the person you want to record something and to keep quiet lol).

8) The Z3 is waterproof and currently in London it has been raining alot and last year i was wearing a tracksuit bottom and top and it rained really heavily and despite my s4 being in my pocket it still got somewhat wet and that was the end of that working without a hitch, so after just splashing 630 on the note 4 i rather not take it outside in this weather unless i am going in my car. Annother example is on saturday I took my daughter to legoland for her 4th birthday and while we were there the weather was a bit miserable and it did rain at times and had I just had the note 4 with me at the time some of the pics I took I wouldn't have been able to as the phone would have got seriously wet, whereas with the Z3 no issues just continued to snap away.

9) The Z3 just feels smoother to use at times is the faster of the two to opening the main apps I use: Call log, phone book, text messaging, settings, camera, gallery/album, music player, whats app. Though scrolling around etc is faster on the note 4.

Loading dolphin browser they are the same but loading web pages and connecting to wi fi/4g the note 4 is faster.

Closing apps they are the same I have tried this several times and despite me having big hands the Z3 is easier to use one handed. Sonys ram usage management is better aswell, I don't know if its a good thing or not but the Z3 always has more ram available at any given time both phones have the same apps on them aswell.

So for those reasons right now I use the Z3 as my main phone and the Note 4 is for note taking/all the multi tasking stuff and playing games.

Its also a nice change from having Samsung as my main phone I mean I have had the Galaxy S, S2, S3, Note 2, S4 & S5. I have had the Xperia S, T, Z & Z1 too but for me they were lacking vs the Samsung at the time imo in terms of audio volume, loudspeaker volume, call volume from earpeice, camera/video quality + I found the cameras quite slow to focus and battery life so I never ended up keeping the sony phones for a long time. However Sony did address alot of these issues with the Z2 but I still found the audio volume lacking a bit and chose to go with the S5 instead as it was louder, however the z3 imo as stepped up the volume so I decided yep I am going to get it and I mean just look at the Z3 is looks stunning awesome looking phone! not that the Z2 wasn't a looker but the Z3 is more refined with the founded corners for me.
