1. Gallery -the tilt is really annoying sure aesthetically it's cool but practically, its horrible to use. -the sliding often causes an 'over-slide' and makes the middle column between 3 annoying to open. the slide is just not smooth, it's like having pictures in between 2 pages of a book -unable to organised the gallery -full of random crap eg, pictures from greader, or facebook tags, or wtv.. i have 'whatssap' picutres and the normally gallery. when i send a picture through whatssap, it causes me to have double of the same picture in my phone. idk about most ppl, but i like my folders well organised and this is annoying!! -No settings to change to simple settings! if i had a choice i would rather use the normal gallery folder from nokia like 10 years ago.. at least it was easy to view pictures and organize them 2. screen -since using it about 3 weeks ago, my screen often becomes inactive and i have to tap it multiple times or go back home to reactivate it. im not sure why that is. There has been times when i wanna unlock my phone and i drag my finger across, it will only detect it half way through the screen. 3.Hanging and lagging -happened on the first day i got the phone, hangs pretty regularly. not so often now but still when i run apps it occasionally hangs.. how does a new phone hang? kinda retarded.. -lag happens almost always, im not sure where this problem comes from but my iphone (no im not a fanboy but its a good comparison) took 2~3 years before the apps lag while i use em.. 4. heat sensors -i reckon this bit was unnecessary.. it gets in the way.. someone it doesnt work when i want it to and sometimes it works when im playing games.. can you imagine playing a game and suddenly i get sent back to my home screen and i gotta restart from the beginning in my game I hope the people in charge would focus on fixing some of these problems rather than keep producing new models.. at the same time.. I wonder if other people are having similar issues such as mine and think this phone has the potential to be awesome but really fails in certain aspects..
