Disgusted with Sony Mobile phone support

Question

Hi. I was thinking of getting either the Xperia M2 Aqua or the Z3 Compact. My main concerns are:
1. Asking for the Android version
The lady on the other end of the line albeit being polite says its "4.4" and that is what her "system is telling" her. This is itself is very inaccurate as there are other Kitkat versions of phones such as 4.4.1 / .2 / .3 / .4? Being on a Customer Support Line and working for Sony Mobile she should be more aware of the different versions and she should have asked a 2nd-line tech support person which she failed to do so.
2. Known camera issue with the Z3 Compact
Issues such as the overall screen & photo quality being more of the "cooler" side (with pictures seemingly less natural, less sharp, less contrast), slow camera speeds, an "overwhelming" LED flash during night shots are all well documented on very well-known websites such as GSMArena. There seem to be a not-so polished, confusing, & low-quality camera software and an update is needed. The lady kept saying that in her own experiencre she did not encounter these issues. She refused to recognise the issues i have mentioned based on what i have read & seen from this very well-known tech websites as it was pretty much useless to base my opinions on phones in stores as the phones will either be on demo mode, are turned off, software is not updated, camera is covered by the phone holder, phone not connected to a wifi or there are no media files to try out. 5 out 5 times i went to O2, Vodafone, Three and Carphone warehouse stores this has been the case. 
I have told the lady to at least make a note of my opinions, comments, complaints & suggestions and to forward it to the relevant people in Sony Mobile which she says she will be doing.
3. Lollipop timeline
The phones i have mentioned have been out for months now. Lollipop has been out since November. Google themselves said that 1. they have made a way to make sure the Lollipop SDK or API gets to the OEMs (such as Sony)  in order for updates to hapen in an early manner and 2. Google stated that they would like to see updates to the latest Android version would not exceed 6 months which in my opinion is very late. The time a new Android version comes out there should be a "limit"of 3-4 months to update current-gen, flasgship phones and 6 months for the mid-range ones. So with those facts in front of us...why still no Lollipop timeline update?
The bottom line is your profits are slowing down and Sony is cutting on jobs. For people to like Sony phones again you must take in these opinions, comments, complaints & suggestions from us users, incorporate them on current & future software and hardware products coupled with timely and early and "as often" software updates then this would be a better world. I have had Android phones for the past 4 years and although not having a computer degree i think i know pretty much how phones work, etc.
Dear Sony...IMPROVE your customer service over phone (include a chat service please), LISTEN  to end-user complaints & suggestions, UPDATE in a realistic/timely/early manner and BE UP TO DATE to market and consumer trends.

Answer 1

I have noticed two known bugs & issues in my Xperia Z2:
1. Alam Clock
This alam clock bug appeared in my Z1 weeks ago and my current Moto G (4G) phone. When my phone is on Silent mode I set the alam clock to ring even on silent. When the alarm goes off in the morning its either i don't see a slider to cancel the alarm or it rings but i have to go to the alam clock settings and go to delete alams and the alarm stops which is 2-3 steps more than the slider. I had to resort to a 3rd-party alarm clock which helps but prefer the 1st-party one. Can anyone explain this?
2. Charging
This issue again is not confined to the Z2 but also to my Moto G and my Nexus 5 which i had weeks ago. Charging the phone, regardsless of how many percent left is on the battery, it causes the screen to go "haywire". What i mean is the screen is almost unusable to the point that multiple tasks are being done at the same time i.e. opening Messages, pulling down the Notification panel, going to Album, etc. I have seen videos on Youtube and i'm not sure if Sony is aware of this. Any advice?
3. Performance
I cannot fault the performance of the Z2. But i'm not the type who do benchmarking tests, etc. I still find sometimes some lag and is a tad slower than my Nexus 5 which has a slightly the same specs. I have speeded up the animations speed under Developer Options but i don't know what else to do.
I also do not believe that by resetting the phone these so-called bugs will go away as this seem to be a "default" advice whenever you ring customer support. I have reset the phone twice and they are still there.
Please advice & help. Thanks.
