There should be a zoom-in or zoom-out feature anywhere within the map area, and a maximum or minimum zoom-in or zoom-out ratio.
-
Marker text and icons should remain the same size at each zoom level of the map.
-
When displaying the map, it should be either north up or the front of the car up.

sound test
Adjust the ringtone volume to the minimum. The actual ringtone volume should be minimum or turned off. Is it normal?
Gradually increase the ring tone; the actual change in the ring tone should be from small to large to see if it is normal.
Adjust the ringtone volume to the maximum; when the ringtone is played at the maximum volume for a long time, there should be no abnormality such as noise, pitch change, or speaker damage.
Gradually adjust the ring tone from maximum to low; the actual change in ring tone should be obvious from high to low; whether it is normal.
time test
Set the clock and date to match the local time and date. During the entire test period, do not change the base time at will unless specifically required to change the time and date.
Generally, after the date is set, the day of the week is automatically generated and should be accurate.
Using 24 hours as an observation period, compare the error between the navigator time and the standard time.
If you set a time and date that does not actually exist, such as 0, 0, 13, 32, etc., or if you set an unrealistic time and date such as February 29, 2003, the navigator will not accept it and will provide a correct prompt. .
After setting the clock and date, turn it off normally, remove the battery, automatically shut down, etc., and then turn it on again. There should be no errors in time and date, that is, keep the clock running normally.
After shutting down, unplug the battery and observe whether the clock can continue to run normally for the longest time.
Picture browsing function
Browse JPG pictures, click on the automatic, manual, previous picture, next picture, zoom in, zoom out, full screen button, and check whether the function changes normally according to the operation.
Check whether the display is complete, whether the color is normal, and whether there is any blurred screen.
Support image formats.
Interface information test
Interface text content check: typos and garbled characters.
Whether the displayed information changes accordingly after the menu changes function.
Multi-language display check: Are there any typos or garbled characters?
The correctness of time display: especially the time display of ultra-long MP3.
Correctness of progress display: Check whether the progress display is accurate.
The scroll bar in the playlist shows: The file exceeds - screen. Is it easy to cause screen blur when scrolling the scroll bar quickly?
The correctness of the prompt box: Prompts must appear where the prompts should appear, such as deletion prompts, low battery prompts, memory full prompts, and key lock prompts.
GPS
Go to settings and check GPS status.
Go to Settings - Location & Security Settings.
Check GPS satellite positioning and Allow access to my location, Wi-Fi and mobile network location information.

Can GPS positioning be used in airplane mode?
Finally, I would like to thank everyone who reads my article carefully. Reciprocity is always necessary. Although it is not a very valuable thing, if you can use it, you can take it directly:
This information should be the most comprehensive and complete preparation warehouse for [software testing] friends. This warehouse has also accompanied tens of thousands of test engineers through the most difficult journey. I hope it can also help you!
