DYU Smart Bike Group is Going to Update Its E Bike APP in 2019

Recommended Posts

After 1 year test of the APP from DYU e bike users, DYU group has gathered enough information of the user experience on the APP and is going to update its Android and IOS APP soon in 2019. Hopefully, it will be updated in May 2019.

According to the Google Play data of the Android system APP, Crashes and ANRs by Android Version is serious and its rate going up with time passing by. Therefore, the new android APP will mainly focus on the solution of the APP crash problems.

According to DYU engineer, most APP crash problem is caused by the phone compatible issues. As we all know, the Android phone does not have a standard of software and different phone usually has different Android system, which is the main reason causing the crashes.

Some users have very old Android system while others have the latest Android system on phone. The different system makes a big problem in the compatibleness of the APP. Therefore, it's not a big problem when you failed in starting the APP, it's normal and don't worry. Besides, the functions of the APP is unnecessary in most riding occasions. And DYU group is going to launch a new version APP soon dealing with the crash problems.

Android Version
SEE DETAILS
1. Android 6.0
2. Android 7.0
3. Android 8.0
4. Android 7.1

Crash problems have been found in multiple Android phones like:
GE LG K4 (lv1)
Acer A3-A30 (omega)

Samsung Galaxy Note9 (crownlte)
 
And the DYU APP team will include those phones in the compatible database in the next version of the APP.
 
Very sorry hearing about this, but please don't worry, following users, 
”It keeps crashing on my Samsung Note 9. Please fix the issue“ Le Fear
”does not detect my device. beug the app“ Cyril Abraham
”Unable to work - Huawei Mate 20 Pro If this app doesn't work on my phone“ Cedric Poh
”it keeps crashing!“ Telvin Goh

...

Though DYU e bike has an excellent riding experience, our users who like the art of the ebike are the group who pursue perfectness. And they will make it happen.

The velocimeter of the LCD display and the app IOS don't match when real speed in the LCD is over 25 km/h

i.e:

Test has been made on DYU D3+ 1) Cruise mode On, 2) Speed settings 30 km/h, Start up accelerator

LCD=23,4 then Ios app=23,4 that's ok
LCD=26,2 then IOS app= 24,2 don't macth
This means that the app software does not admit values over 25 km/h

Other minor bug in the IOA app (map screen when you discrad to save the track)
Cancle >>> Cancel

Thanks for your help!

Thanks for sharing. The speed is also related to the rider weight and road condition

What do you mean of this?"Other minor bug in the IOA app (map screen when you discrad to save the track)
Cancle >>> Cancel"   and how do you want to do with the track?

Hi!

I know that max speed is 25 km/h but when you drive downhill or in good conditions speed can go over 25 km/h. In this case, velocity above 25 km/h, is clearly showed on the LCD display (right hand accelerator) but not in the mobil phone app which shows always speed below 25 km/h. I will try to explain this bug with some pics in next messages... thank you!!
