Proximity Sensor Finder does what it says - it helps you locate the proximity sensor on your Android device. It is a very simple, purpose-built app with no flashy graphics.

Proximity Sensor Finder tells you a few things about your device:

1. Does the device have a proximity sensor?
2. Is an object in close proximity detected?
3. Does this device support actual proximity distances or just "covered" and "uncovered" sensor states?
4. For supported devices, exactly how far away is the object?
5. How long has the sensor been covered?
6. How much power is the proximity sensor consuming?

We developed Proximity Sensor Finder as an internal testing tool but it soon became apparent that there was a need in the market for just such an app, so we decided to ship it and make it free!

Internet and location permissions requested are just for ads, no other data is transmitted or received.

* Uses your phone or tablets proximity sensor
* Shows continuous values from the sensor
* Plots a time series chart
* Additional info about the hardware and capabilities

Phone tester is a free app that allows you to analyze and test your device's hardware and components, to make sure everything is operating correctly.
You'll be able to test the following:

***SENSORS***
Accelerometer, gyroscope, compass, proximity sensor, pressure sensor... You'll be able to check which sensors are supported by your phone and all the information and values provided for each sensor.

***WIFI***
You'll be able to check your LAN status: internal & external IP, gateway, DHCP server...

***TELEPHONY***
Signal, network type, external IP, SIM data...

***GPS***
You'll see the real data provided by the GPS: satellites, latitude, longitude, altitude, speed...

***BATTERY***
Level of charge, time on, temperature, health...

***MULTITOUCH***
How many points of contact does your device recognize?

***SYSTEM INFORMATION***
Information about hardware and software like CPU, RAM, kernel version, screen...

This app is similar to EVEREST or AIDA64, but apart from showing the components and system information, it also shows sensors readings.

The Pro version of Phone Tester displays more information (CPU speed, phone memory, sd card memory) and removes the ads.

Reenable proximity sensor on call.

This app requires root access, if you don't know what that means don't install this app

If you have problems with your proximity sensor? Or the screen stays black after a call. It's most likely the sensor, this app will fix that.

Tested on:
Note II, GT-N7100

Please send a mail to vrognaas@gmail.com if you encounter any problems.

I am a developer in the inital phase, i would be very happy if you would buy me a bee.

*** ROOT ONLY ***

This utility can be used to recalibrate a dirty or worn proximity sensor on your HTC rezound. If you are not rooted this utility will not work for you.

Want to feel what gestures can do? here's an application which will let you turn of your screen just with a swipe!! yes that's right!! All you have to do is swipe your hand over the proximity sensor (Located near the earpiece on top of the phone).

https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FQMVBPXQ6PERN

Features:
1) Turn off the screen by sliding your hand
2) Turn off the screen by Covering the sensor for a duration of time (Tap and Hold)
3) Turn on the screen by Covering the sensor for a duration of time (Tap and Hold) - Note: This can cause Battery Drain
4) Enable screen on/off during calls only
5) ScreenOff shortcut, to turn off the screen by launching the app.
6) Based on your device select the sensor of your choice, or the one that's available and configure their values, as they are different for different devices.

Motivation to build this app:
1) While the phone is in pocket, and you have your bluetooth headset connected, even though you can answer your call with a click of bluetooth headset button, because the screen goes on and remains on, your call may hang-up or go on hold or probably few buttons may get pressed, isn't that annoying?
2) Lot of android phones don’t turn off the screen when phone is held close ear (You may end up hanging up on someone)
3) Accidental call pickups: Since capacitive screens are sensitive to touch as well as heat, An Incoming call gets picked up automatically when phone is in the pocket (And we get obliged to speak to annoying calls)
4) Its Cool!!!
5) If you are a HD2 user, you would know the pain. Many users have replaced that hardware buttons due to usage!!!

NOTE: To un-install, go Settings, Locations & Security, Select Device Administrators and disable the ScreenOff App

How does your phone compare with your friend’s phone? Does it have a more advanced accelerometer or gyroscope? What other mysterious high-tech sensors does your tablet have hidden on board, and what do they do? Find out with Sensor Kinetics.

Sensor Kinetics is an advanced viewer and monitor for all of the standard sensors available in your Android device. The new built-in Multi-Sensor Recorder allows you to record up to six kinetic sensors simultaneously.

Written by one of the pioneers of the use of accelerometers and gyroscopes within the modern smartphone, it provides a comprehensive look at the total dynamics of the combined operations of all the sensors.

The app demonstrates the use of the accelerometer, gyroscope and the rotation sensor to control a tilt based view navigation like the RotoView technology by INNOVENTIONS. It also demonstrates the operation of the magnetic sensor, the linear acceleration sensor and the gravity sensor within special graphical displays.

Use Sensor Kinetics to monitor and understand the behavior of the sensors while you change the delay setting or activate/deactivate specific sensors. Each sensor is attached to a sophisticated chart viewer. The Multi-Sensor Recorder records multiple sensors simultaneously at a controlled data rate. If you need to save or share sensor charts, please purchase the companion Sensor Kinetics Pro.

For educational users, the app includes comprehensive help files which provide physics students with hands-on knowledge of how these sensors interact with smartphones and suggest numerous experiments you can perform on your phone or tablet.

Who Should Use Sensor Kinetics?

Developers, students, hobbyists, technicians, engineers... anyone who's curious about what lies "under the hood" of their mobile device!

Test your Android phone or tablet: Sensor Kinetics allows you to test all of the sensors on your device. For example, you can quickly determine if your Android device has a gyroscope sensor and how fast it's operating. The numerous chart viewers allow you to measure any sensor over time and gauge their accuracy and behavior.

Educational: Sensor Kinetics demonstrates the physics of gravity, acceleration, rotation, magnetism and more as these forces are measured by your phone or tablet. The app includes comprehensive help files with easy to understand information and experiments you can perform with the sensors.

App Developers: View in detail the behavior of the sensors used in your apps. Compare the performance of advanced sensors like gyroscope, linear acceleration sensor and the rotation sensor.

This app relates to gyroscope and accelerometer data logging, magnetometer, smart scroll, science, physics, tilt measure, pressure sensor, relative humidity sensor, light sensor, linear acceleration, temperature sensor, proximity sensor, gravity sensor, MEMS, kinetics

Calibration of the touchpad temperature settings
In extremely cold weather or abnormal temperature conditions your phone might not function like it normally should. If you are operating your phone in extreme cold conditions the touchpad of your phone may not react as it would under normal conditions. Any effect to the usage of the touchpad may therefore be caused due the impact of the surrounding environment.
In order to avoid any inconvenience or interruption to the usage of your device, ZTE will provide a user friendly solution to ensure the usability of your device.
This app solves typical touchpad problems through the calibration of the settings on your phone which are then adapted to a lower temperature environment.
All settings are done automatically, one need only install and execute the app on your phone.
Place your phone on an isolated desk (lay some non conducting material between your phone and the desk) then execute the application. While the process is ongoing please keep a certain distance between yourself and the device in order to avoid any unwanted influence during the calibration. The process will take only a few seconds. Once completed you may then return to main home screen and start using your phone normally.
