What has disappointed you most about a smartphone?

one of my phone is note 1, which have an 4.1.2 update but the worst thing is the battery life. my phone stays for 2-3 hours and i need to recharge 1-2 times daily. but iam happy with that. i have brought 3-4 battery but they don't play their role. this phone is also a water proof yes i accidentally put my phone in a washing machine for 1 hour but he was still alive. now i use this phone for experimental purpose.

i have a lot to say about my smart phones .. open up the threads

My touch screen just doesn't work suddenly! I was wondering what would have caused such a problem. I then realized whenever I placed my mobile in my Jean, it got pressure. Finally parts of my touch screen are out!

That's the worst thing and I hate it now coz I can't even type with correct spelling

My first Android phone was a LG Spirit ms870 and it developed a taste for SD cards. Totally clobbered them. Helped justify new HTC One M8 which I totally love er like a really lot.

When I bought my Note 2 I decided to not have case or screen protection, because it's already big itself, and it had Gorilla Glass 2.
On the 10th day from standing landscape it fell onto it's front (so the weightpoint fell like 4cm) and it cracked the screen. Such a disappointment.

I've (luckily) never had a huge disappointment, but the Xperia Arc was a let-down. As an X10 owner this was supposed to take the best parts of it (design, build quality, Sony Ericsson audio/visual development) and add technical specs to make it a class leader. It was one of the best looking smartphones, but it was fragile, a generation behind spec-wise compared to the Galaxy S2, and Sony Ericsson were at that time really slow with updates.

For me it's always battery life and camera (but I've had both the Nexus 4 and Nexus 5, so...)

But even with all the flagships models I use daily at work, I'm never fully impressed by any of the cameras, although the Galaxy S5 probably comes the closest in terms of results and the G3 for simplicity/clean app interface. I just feel like the ''perfect'' Android camera is yet to appear.

And while the S5's UPSM and general battery optimizations (not to mention those on the G2 and G3) are impressive, I still think battery life tends to be the biggest issue/letdown for every Android owner.

Oh, and I should also add crappy updates to the list! That's always a massive disappointment!

For me, the simple thing that the Galaxy S5 doesn't have FM. I am spending all my data on listening to songs.
