Using the phone for 8mo now, black version... Isn't rooted yet (will wait for lollipop update and then will see what will i do with the phone) Complaints -
* Very Low free space(the only one 16gb version has 12.83gb of usable space) after setting up my phone i struggle to keep free 1gb of free space and constantly need to delete or copy photos/video or files elsewhere to have some space on the phone.
* The body paint job isn't great, i have been using the phone with the s-line TPU case and screen protector from the day i got it, but from some sand crystals which got behind the case the paint on the back has gone away and the back is looking ugly like i even didn't use any case. For Sensation i used the same type of case and this problem only started to appear when using the phone for 2years and more.
* And don't get me started about the shh... main camera. downgraded 4 ''ultrapix'' is a massive joke that is ONLY somewhat view-able in the phone 4.3'' screen because it
IS DOWNGRADED and it's not the same as the big brother's has (M7 or M8)
See the picture test comaprison here
In comparison It's lacking the clarity and the sensor detail, and because its only 4m/u pix this is seen right away, so the camera sensor inside is much much MUCH cheaper that the big brothers has, even if it should be ''the same'' 4upix camera!
From day1 i had took like 100s of pics but i only had managed to take few good looking pics that turned out ok and those pics can be view-able on any bigger screen, every other pic is a total ****** that cannot be view-able in larger screen than the phones.
( i know that any phone camera isnt 'pro' camera, but now im not comfortable to show to ppl any pics i took from this phone to big screen! with sensation's 13mpix i was showing pics to my friends/family on larger TV screen like a boss, now with this im showing only on the phones screen cuz on 42'' 1080p TV screen, 4mpix resolution pic isn't a view-able picture but its a color palette

)
My conclusion -
If my sensation didn't broke so fast i would wait for one mini 2 price to drop(it was just released) from overpriced 'new' phone price tag to normal price tag and buy it, but my senny died fast and i was forced to buy a new phone, 'mini' had a sweet deal in my country so im stuck with this for now.
If you are considering of buying 'one mini' version now then most definitely choose mini 2! It is much much better with ok 13mpix main camera that isn't shy of bigger screens in any pic taking situations, better front facing camera, expandable SD card so you wouldn't worry abut free space, build-in NFC, and better battery life.
