Motorola Droid Razr XT912: Death of Tech Device

The Motorola Droid Razr XT912 seems like a nice enough smartphone. Small, slim, with a carbon fiber back. Friend David bought it from, I think Canada Computers, refurbed. After using it for a while the battery life was reduced, then he used it as an MP3 player. In the end I received it and used it as a desk clock. Finally, it would no longer reboot, seemingly in a boot loop.

After many years of careful use, the headset that came with a long gone Blackberry smartphone lost sound in the right ear. If I wiggled it “just so” the sound would reappear, but with any further movement the sound would again be gone. It was clear that the wire would need to be cut back and the 3.5mm phone plug would need to be replaced. Because I do like the feel and the quality of the headset and mic, this was worthwhile to repair.

Freedom/Wind Mobile Texting Error Message, but can Talk

Little Weed had a problem with his Google Pixel and Freedom Mobile. While he could call people he could not text, and received an error message “Can’t send message with freedom, error 8”.

We went to the Wind store and this is what the guy did. It did take a couple of seconds to kick in:

settings > network and internet > mobile network -> advanced > access point names > … (top right corner) > reset to default

Sim card was fine. I’m glad the guy knew his stuff.

LG D-852 Smartphone: Screen problems and fix

This is an LG G3 smartphone with the back and bezel removed. The LG D-852 has some differences. Note the brown flexible flat cable at the top (yellow arrow). The LG D-852 has a rectangular and square one. Remove and reinstall both.

My LG D-852 suddenly developed screen problems, which included fading to black from the edges, then black horizontal lines, and finally just all black. It seemed odd that only today this would happen.

I found this post and decided to investigate. I took the phone apart, unplugged and reinstalled two connectors, which fixed the screen problems. It took 3 minutes, a very small screwdriver, and no additional cost.

LG Optimus Net p500h Smartphone from Koodo: Unlocking

LG p500h Optimus One smartphone, circa 2011, unlocked from Koodo for use on the Bell network, Canada.

LG p500h Optimus One smartphone, circa 2010, unlocked from Koodo for use on the Bell network, Canada.

Somehow I have an LG p500h smartphone, which was locked to Koodo. As Canadian law has changed, forcing mobile service providers to unlock phones free of charge, I went on Koodo’s Facebook page and requested an unlock code. They gave it to me and I was able to unlock the phone. I put my Bell sim card in and it worked! Yay, I have a 2011 phone, but it works!

Smartphone: Tool of Evil in China

Every tool used by humans can be used for good or evil. It is up to the individual to determine its use. Smartphones are some of the newer tools for modern living. Their longer-term implications for everyday use are as yet unknown. While we in the West, where I see this in Canada, take steps to preserve privacy, this is untrue in China. The Chinese government has turned the benign too of the smartphone into a personal tracking device for its own political purposes.

Our Asus Zenfone 2 Z00ADA ZE551ML smartphone has a broken camera. The selfie camera simply does not initialize in the camera app, which says it is not there. We wondered why. There are a lot of complaints about this broken camera, so the problem seems common. We decided to take the phone apart, to take a look and ensure that all the electrical connections were tight. What we found was that the electrical socket that connects to the selfie camera was very cracked. The socket is so small as to be irreparable. This socket could not have been damaged by wear and tear, as all the other components around the selfie camera, including the forward facing camera, are in pristine condition.

Smartphone and Texting Addiction: Possible Causes

Well known, is that smartphone use, specifically texting while driving and walking is dangerous to both the person and to all others either on the road or sidewalk. There is no question that smartphone use has an addictive nature and seems to be able to tap into something primal in the human spirit.

Recent news articles have come out to try to explain what is happening and why the addiction happens. Here is one on Texting and Addiction.

1. Sending a Text creates a “TR”, a novel brainwave in the prefrontal cortex on both sides of the brain, but only acting when sending a text, not receiving one, or talking on the phone.

La Presse journalist Patrick Lagacé Surveilled by Police

La Presse journalist Patrick Lagacé just found out his phone was tapped by Quebec police, one of 7 other Quebec reporters. His meta data and geolocated movement were legally obtained, through 24 court ordered warrants for police surveillance. This is shocking.

DS ()Diana Swain): We’ve focused on journalists, and that’s what we’ve heard about this week. But should Canadians at large be concerned about this? People who are not journalists?

PL (La Presse journalist Patrick Lagacé):
