Solutions for Android phones with recent Google Play system update?
If the date of Google Play system update on your phone is later than June 1, 2024, it will be more difficult to mirror your phone screen to Tesla with the Tesla Display app.
The problem
Because recent Google Play system update (June 1, 2024) blocks the network requests to the virtual IP address through personal hotspot. We have to adapt more complicate solution to mirror phone screen to Tesla. This page will show the best solutions we can find out so far.
Check app version first
The version of Tesla Display app must not be older than 5.27
Solution A (only effective to a subset of users)
If the internal IP address your mobile phone obtains from the mobile carrier happens to be outside the range prohibited by the Tesla browser, the solution is easy.
1. Check the "Disable SSL" option on the setting tab
2. Tap the "start" button, choose "Phone screen"
3. If you see an address that is NOT http://7.7.7.7:7000, it means Tesla browser can access that address after Tesla is connected to the personal hotspot of your phone.
Solution B (require two Android phones)
If Solution A cannot work for you, you can try Solution B.
Solution B requires two Android phones.
One phone is the phone we want to mirror its screen to Tesla, which has installed the latest Google Play system update. We call it the new phone.
The other phone must not install the Google Play system update after June 1, 2024. We call it the old phone.
These two phones and your Tesla vehicle have two schemes of network connections to meet different needs.
Connection scheme 1
If the old phone can enable personal hotspot using Wi-Fi instead of cellular data, you can choose this scheme. No SIM card is required for your old phone.
Network connection:
1. The new phone turns on cellular data, and enables the personal hotspot "Wi-Fi N".
2. The old phone is connected to "Wi-Fi N", and enables the personal hotspot "Wi-Fi O".
3. Your Tesla vehicle is connected to "Wi-Fi O".
App operations:
1. On the new phone, launch Tesla Display app, check the "Disable SSL" option on the setting tab, tap the "start" button, choose "Phone screen"
2. On the old phone, launch Tesla Display app, tap the "start" button, choose "Forward another phone screen"
3. On Tesla browser, access http://7.7.7.7:7000 to see the screen of the new phone
Connection scheme 2
If the old phone can only enable personal hotspot using cellular data, you must choose this scheme. You must insert one SIM card into the old phone for personal hotspot.
Network connection:
1. The old phone turns on cellular data, and enables the personal hotspot "Wi-Fi O".
2. Both your Tesla vehicle and the new phone are connected to "Wi-Fi O", and enables the personal hotspot "Wi-Fi O".
App operations:
1. On the new phone, launch Tesla Display app, check the "Disable SSL" option on the setting tab, tap the "start" button, choose "Phone screen"
2. On the new phone, Swipe down from the top of the screen, long press the Wi-Fi icon, select More Wi-Fi settings, tap on the > to the right of "Wi-Fi O", and remember the IP address, assuming it is 192.168.3.xyz.
3. On the old phone, launch Tesla Display app, tap the "start" button, choose "Forward another phone screen", input the IP address 192.168.3.xyz, and tap submit
4. On Tesla browser, access http://7.7.7.7:7000 to see the screen of the new phone
Hints:
a. The new phone must launch Tesla Display before the old phone
b. To control directly on Tesla's touchscreen, you should enable "Control on touchscreen" on the new phone.
c. On Tesla browser, you should access the URL shown in Tesla Display on the old phone.
d. You must disable automatically system update of the old phone
e. Only "Phone screen" of the new phone can be forwarded.
f. You'd better test if the old phone can mirror its phone screen to Tesla first.
Solution C (require a rooted Android phone)
