Phone Compatibility with Carv

October 1, 2022

4 min read


Carv is compatible with any iPhone that has a minimum of iOS 15 installed, though we recommend using the most up-to-date version of iOS.


Carv requires a minimum of Android 8.0 to run, and your phone must support Bluetooth 4.2. It is also recommended that you use a phone which has a barometer in order for Carv to function most effectively. Some Android devices need to have Battery Whitelist or App locking enabled when using Carv. These include some Huawei, OnePlus, Oppo, Realme, Samsung and Xiaomi models.

Read more about specific Android devices we have tested here.

Other devices

Carv requires GPS service and a barometer is also strongly recommended. Other devices which have these features should also be able to run Carv, but we do not guarantee compatibility with any devices other than those specified explicitly.

Whichever device you are using, ensure that you give the app permission to use location and that Bluetooth is switched on while using Carv.

If your phone is a previous generation of one of the phones listed above, we would not anticipate any issues using Carv with your phone.

Bluetooth issues

We transmit data from your Carv trackers to your phone 20 times per second over Bluetooth. The following devices have been shown to be unable to meet this demand, and therefore we do not recommend using Carv with these models:

  • Samsung A12 and other similarly priced Samsung phones
  • Huawei P30 lite
  • Nokia 1 Plus
  • Honor 8X

Snapdragon 865 Bluetooth issues

During our testing programme of 2020/2021, we encountered a strange bug on a brand new flagship phone, the OnePlus 8T. This bug seemed to happen at random, causing the Carv app to stop detecting turns whilst skiing. It was, and still is, one of the larger headaches of the season for us.

The bug wouldn’t happen consistently and there was no pattern to explain its occurrence. This meant that reproducing the bug was very difficult.

Over time, we noticed a trend: the worst-affected devices all have the new (as of 2020/2021) SnapDragon 865 SoC (System on a Chip). These include:

  • Samsung’s S20 range
  • OnePlus’ 8 range
  • LG’s V60 ThinQ
  • Sony’s Xperia 1 & 5 (mk.2)
  • Xiaomi’s Mi 10 range.

To read more about what this issue is please see our full article on Snapdragon 865 issues here.

The following phone models also exhibit this corruption bug very frequently and as such we have had to mark them as 'incompatible':

  • Moto G8 range phones
  • Moto G30
  • Motorola Defy
  • Motorola E30
  • Motorola Motor G Play
  • Samsung Galaxy A5
  • LG V20
