How to update CyanogenMod using the automatic updater

Tue, 2016-08-02 07:17 by admin · Forum/category:

First thing I would do is a system update, which is automatic after you start it and may take between half an hour and one hour, depending on how many apps you have installed.

The battery should be nearly full or you should have the phone connected to a charger or a computer. Tap Settings, About phone, CyanogenMod updates (the top choice). Tap the circular arrow symbol (top right) to get the latest updates.

Charging the OnePlus One smartphone

Sat, 2014-08-23 14:36 by admin · Forum/category:

Since I could not find any specifications, I conducted a test. I measured one charging cycle from 0 to 100%, so I have an estimate now. I first discharged the battery to 0%, until the phone powered down. Then I connected the phone to the original power adapter and occasionally noted the charge percentage and the clock.

The first result is that the phone reached 50% after 45 minutes, which is normal for a smartphone, perhaps even a bit on the fast side.

SIM-Karte für Smartphones in Deutschland

Hier kommt ein Kauftipp, aber nicht für ein Smartphone, sondern für die darin steckende SIM-Karte. Es gibt eine neue SIM-Karte, die mit einigen ihrer Eigenschaften alle anderen in den Schatten stellt.

Sie heißt simquadrat und stammt von sipgate, einem Unternehmen, das sonst IP-Telefonie anbietet. Was sie meines Wissens von allen anderen SIM-Karten unterscheidet, sind eine Reihe besonderer Eigenschaften, ganz besonders das sehr preisgünstige Telefonieren im EU-Ausland und ins Ausland generell:

GPS takes a long time to get its position

Mon, 2013-07-29 15:36 by admin · Forum/category:

The first question is whether you had an Internet connection. Without Internet it takes much longer for the GPS to get a position.

To get a position fix, the GPS needs the satellite orbit data first. There are two ways to get these:

  1. Over the Internet
  2. From a GPS satellite

With an Internet connection a typical time to the first fix is 15 s. Even without an Internet connection the time for a subsequent fix, less than 4 h after the phone already had one, is also around 15 s.

GASAG, the Global Android Stay-Awake Gesture

How often has it happened to you that your phone went to sleep and switched off its display while you were looking at it?

For reasons of conserving battery charge and AMOLED screen wear I have set my phone to fall asleep after one minute of inaction. This is usually enough to keep it awake while I read an article in the browser, because I have to scroll down approximately once a minute.
