Nexus 5 no sound - The Ultimate Fix

"When I play an audio or video file I cant hear anything through my nexus 5 speakers, but when I connect my headphones I can clearly hear the sound."

I was experiencing the same problem lately. I googled everything I could to fix this problem but none of the provided solutions seemed to be working or fixed the problem permanently.

Sometimes I get the sound for short period of time and then it’s gone again and I couldn’t figure out what was causing this problem. Until today …

How to fix nexus 5 no sound problem?

  1. Open your fridge 
  2. Put the Nexus 5 in the fridge for 2-3 mins
  3. Open the fridge again and take out your Nexus 5
  4. Hooray! You have sound again!

This is really works, I just tested it :) I’m assuming the sound problem is coming from overheating at some point, can be just a small raise of temperature to cause this problem.

Oh and, my wife just asked me: “What the h*** is your phone doing in the fridge!?” - I just smiled :)


Skype birthday notice

I always found the Skype birthday notifications great because they reminded me about my friends birthdays, but on the other hand also a bit confusing.

1. You receive a notification in sidebar next to username, just like a regular Skype conversation (1), which made me think that the person actually sent me a message. This may be good if you want to force user to check the message, get disappointed that it is actually a birthday notice, then find it actually helpful because you can send him best wishes and then never really buy your friend a Skype gift card. Besides the fact that I’m always against intentionally forced mind games with users I find this confusing.

2. First word I always read when I open the conversation screen is “Forgot …” which makes me anxious. This may be good to trigger user emotional responses and decision making but I doubt the decision made here would be towards buying your friend a Skype gift card.

This is why I slightly redesigned this notice to be straightforward and engaging at the same time.

Oh and yes, I had some spare time to do this, not that I’m totally addicted to redesigning other peoples software :)

Cheers and I hope you like it!

The Web Designers’ Guide to Photo Selection

Photographic images grab our attention and trigger an almost instantaneous response when we encounter them. They are therefore an important part of any website we create. Photos play a significant part in determining our first impression, but they can also tell us what the site is about and can be a huge factor in earning trust. 

When used properly, photos are very effective and can quickly send the intended message to your audience. However, using the wrong photos can degrade your users’ experience. How do we choose the right ones?

UX Developers Aren't a Thing


UX is not made of code. Developers work with code. So what does a UX Developer do?

I just want to call your attention to a problem that seems to be growing instead of dying the horrible death it deserves:

Job ads for “UX Developers”.

For the record: developers are great, smart, valuable…

4 Types of Customer Analytics Data to Collect


Want to have a complete picture of your users? Then you’re gonna need more than one type of information about them. 

Read the linked article (it’s fairly short) and ask yourself if you know all of those things about your users. 

If not, how could you find out?

10 Ways to Pretend You Know UX (When You Don't)


The most amazing thing, to me, is when people try to pretend that they have expertise when they actually know very little. This is an epidemic in UX. And like any good vaccine, I have to infect you with a small dose so you can kill it in real life. So here is my guide to how it’s done.

UI Design Rules

A reminder to myself of some well known User Interface Design Rules.

Booknotes 001 - Designing with Mind in Mind

My notes  from the book Designing with Mind in Mind by Jeff Johnson

This has been a very nice read. I recommend buying this book and reading through all the sections and research findings provided in the book. It will help you a lot when making critical decisions when designing your next interface. 

DOET - Elevator with(out) controls

"I just found a Norman door, it was really difficult to use" - sounds familiar?  It is a popular quote from the book "Design of everyday things" by Don Norman.

So, I went into this building and needed to go to 14th floor. I came to the elevators (6 of them, 3 on each side) and wanted to call one. I couldn’t find normal controls like you see on normal elevators these days, instead I was introduced to something that looked like a phone keypad. It looked like this:


I was confused at first, I thought maybe this is something for employees of the company to enter their special code or something. Notice the “star” button? What the heck is that!?

On the display it said: “Please enter floor number”. I “typed” 1 and 4 and the message on the display changed to something: “Elevators to come A, B..” - and I don’t remember after that because the message quickly disappeared and returned to default state. I was confused but….

Eventually, one of the elevators arrived and I stepped inside. To my surprise inside the elevator there were no buttons or controls at all. I was presented with this:


Nevermind, I was on my way to 14th floor. 

After the meeting I had to go down of course :) I pressed number 0 on the left keypad and again display showed some message very fast and disappeared, and in that very moment one elevator just arrived on the other side (right). I turned around and entered that elevator, door closed and …. nothing happened. I was trapped inside! Since there were no buttons to choose to which floor you want to go, I couldn’t do much. Eventually I found a small tiny button that looked like if pressed the door will open. It did, I was free again!

What really happened here is that this wasn’t my elevator for the ride as I “the genius” figured it out, because the message on the display told me which elevator I should take or expect to come, since I was using the keypad on the left side. Elevators were marked with letters from A to F, and coincidentally the moment I pressed 0 on the left side, elevator came on the right side. Since the message on display isn’t really readable (except you’re super duper mega uber fast reader) I couldn’t tell I was wrong until I was trapped. 

And finally, I figured out how this “state of the art modern” elevator operates and found my way out of this building.

Imagine you work in this building. You must go to 14th floor and on your way back to ground floor, in the middle of your ride you decide to stop by on 8th floor to visit your colleague. Normally you’d quickly press number 8 and elevator would stop there and you can step outside. Unfortunately that ain’t gonna happen with this one :)

This elevator design probably won several prestige awards for the design of the century in whole universe or something like that.

Till next time when I return with more DOET stuff ;)
