Messenger app only working on WiFi?

Messenger app only working on WiFi? published on No Comments on Messenger app only working on WiFi?

I’m a huge fan of the Telegram Messenger. I’ve been using it for a couple of months now and it’s nothing short of amazing. I have it installed in almost every device I use. I kept trying to get Randy and Chanux to switch to using it and even managed to finally get Chanux to set it up on his android but I don’t see him using it much. Randy kept disappointing me as he usually does these days and simply refused to try it (he also refused to watch Star Wars, so yes, my dear Internet, I think we can safely give up on the guy now).


Anyways I didn’t really write this blog post only to talk about Randy and his awful tastes. About a week ago I noticed that Telegram stopped working in the background while on mobile data and only started working while I’m connected to WiFi. This was really annoying because more than a couple of times I missed all my messages while on the road only to realize that Telegram was offline during my travels. When I get back on WiFi Telegram would notify me about all the messages that I didn’t receive during the day.

This obviously looked like a problem with my data settings that would restrict Telegram from using any mobile data and to my surprise it was all set to normal. Then I thought it was a restriction from the Power saving mode in android and that was also not the case.

A quick search on google led me to a bunch of forums that showed this is not just a problem with Telegram but also happens to be a problem common to a lot of apps that uses background data. And none of them seem to have solved the issue.

I kept looking through the threads and found one suggestion that finally worked for me. It was to reset all app preferences in android. This looked crazy at first but after trying everything I gave up and just did it, and guess what! Telegram now works well on mobile broadband.

So if your messenger app is not working and nothing else works you can do the following:

Go to Settings -> Applications -> Applications manager

Select Reset app preferences from the “MORE” menu and you’re done.


Be warned though. This would reset the preferences for all the apps in your android phone. So only do this if nothing else works for you.

This trick should also fix apps like Slack, Snapchat, Viber or any other app not working on mobile data.


Welcome to User Centric!

Welcome to User Centric! published on No Comments on Welcome to User Centric!

U-S-E-R(This is the post I wrote introducing UserCentric in the official blog at

Hey all! Welcome to the first official post on the User Centric blog! So… what exactly is User Centric??? I truly am glad you asked!

You know all those little complaints/ideas we share on social networks such as twitter, facebook etc. about the products/services we use, and get lost in the sands of time? of course you do! User Centric is the one place that you can share all those micro reviews and unlike normal social media sites, your user experience reviews will be organized nicely based on #Tags.
So what is the difference between traditional product review sites and User Centric? Three words, Ease of use! Most of us don’t have the time to write lengthy reviews on things that we use. But something that we all do is post micro reviews on social networks. We complain about the flaws in products, we post our ideas on features that we wish to see in our favorite products, Why not collect all our micro reviews on a product and organize them in one place so others can benefit from the tips we share? That is exactly why I built User Centric.
What we needed was a system that makes product reviewing fun hassle free! That is why I designed User Centric the way it is now. All you have to do is write your reviews starting with the product name as a #tag.
Review anything you use, one point at a time… Becoming a semi-pro product reviewer has never been so easy! 😀

You can check my reviews page on User Centric at to see how organized UX reviews look like.
We are currently on private beta so if any of you want to grab your preferred username early, you can use the beta code KyXnrTz” at the signup page. Just don’t tell anyone else! 😉

How Dropbox Won

How Dropbox Won published on No Comments on How Dropbox Won

A couple of days ago, I came across something very interesting Dave Winer shared on twitter. It was a link to the application Drew Houston, the Dropbox founder submitted to YCombinator for their Summer 2007 cycle. I opened it out of curiosity and found it very interesting and thought provoking to read. Here’s is the answer from the application, to the  question: What is your company going to make?”

“Dropbox synchronizes files across your/your team’s computers. It’s much better than uploading or email, because it’s automatic, integrated into Windows, and fits into the way you already work. There’s also a web interface, and the files are securely backed up to Amazon S3. Dropbox is kind of like taking the best elements of subversion, trac and rsync and making them “just work” for the average individual or team. Hackers have access to these tools, but normal people don’t…”

The moment I read this I realized how well Drew saw the future of his product way before even anyone else sees it. He had a very clear vision what the product is and how it’d help to solve what he waned to solve. And looking at the success of Dropbox, it’s obvious that he has executed his plan precisely. This sure is a winning mix. I’d be surprised if a product fails to achieve suceess with the founders having this kind of insight about what they’re going to do. I’m sure Paul Graham had his winning smile when he saw this one… well, here’s exactly what came to his mind when going through the Dropbox application Y Combinator received that summer…

What happens when I read this:

File syncing. Superset of backups, which people will pay for. Good. Single founder. Bad. But at least he’s looking for more people. Went to MIT, 1600 SAT. Probably fairly smart. Wrote a poker bot. Now I’m starting to get interested; has the right attitude. Description of the software sounds plausible but generic. Maybe it’s good, but who can tell. But little sister uses it; that’s impressive. Scroll down to what he understands that competitors don’t get. Wow: very concise and unequivocal. I’m now basically sold. Scroll through the rest. No red flags. Did not make the usual joke single founders make when asked how long the founders have known one another. Good answer to what might go wrong. A-. (Would be an A with a cofounder.)

Very interesting indeed. It seems PG sure knows when he sees a killer idea and a brilliant mind behind it.
The application is full of very interesting questions like What do you understand about your business that other companies in it just don’t get?”  and brilliant answers from the Dropbox founder. It’s really worth a read if you are a startup minded person and I strongly suggest that you answer yourself to this application for any products you are building.
Oh and btw, If you haven’t used Dropbox yet, Trust me! you have no idea what you are missing.

How to Unlock the Huawei E220 HSDPA modem

How to Unlock the Huawei E220 HSDPA modem published on 1 Comment on How to Unlock the Huawei E220 HSDPA modem

Huawei e220 or Vodafone e220 is the HSDPA modem we usually get from Dialog Telecom or Mobitel GSM (probably from Airtel) when we purchase a mobile broadband connection. But usually it’s operator locked, so we can’t switch between networks when the current ISP starts treating us like dust, If you’ve read my previous post you know I have my reasons to unlock the Huawei e220 modem I got from Dialog Telecom. Here I’m gonna explain how I did that and I’ll try to be as simple as I can. But Feel free to ask for help if u need any.


Disclaimer: I’m not responsible, nor will be held liable, for anything you do with the information I provide in this tutorial. Use it at your own risk.

Ok, since we are done with the traditional “Disclaimer” Lets see what you have to do.

First you’ll have to download the following tools.
e220 CardLock UnLocker
e220 Updater version
QC Mobile Analysis Tool
And a Hex editor. But if you do it correctly you can do it with an ordinary text editor too 😉

Or you can download and extract this file. It contains all the tools we need for the job, including a lightweight portable hex editor 🙂

Basically, Unlocking the e220 is simple as running the E220 CardLock Unlock tool and entering the unlock code and pressing the “Ok” button. But that’s when you “know” the unlock code.


So how do we find the unlock code for our modem? that’s where the other tools come in handy.

Plug your modem to the computer and run the E220 Updater. Wait till it detects your modem and then press the “Cancel” button. yes! Cancel it! This is just to make it easier for the “real tool” to identify the modem.

e220UpdateNow open the QC BQS Analyzer and click on Hardware forensics menu, select Use Com/USB Port
QCMob-1Now the “QC Com Diag” window should be open. Most of the time your modem and com port is automatically selected on the Serial Com port drop down list. If not you’ll have to select it manually. And then click on the “Send Cmd” button and wait till the message “Successfully sent command” appears on the bottom right.

Now Select ” Read EFS” from the Diag Functions drop down menu and Click the “Lets go” button. When it asks, enter the file name e220.bin and save it. A message saying “Successfully read EFS” should appear.


Now its time to do some hex reading 🙂 Open the e220.bin file from your Hex Editor. And search for the ASCII string Sd, (including the comma) or Search for the for the Hex string 53 64 2c
After few random characters you’ll see a clean 8 digit code. Believe me, it’s easily recognizable and guess what! thats our Unlock code 😀

HexOnce you’ve found the unlock key all you have to do is enter it on the CardLock Unlock utility and click “OK” And your modem is… Unlocked!!! 😀

Hope this will be helpful. I’d absolutely love to know your views on this. Good luck with unlocking your modems 🙂
