Can I still do the test if I’m unable to hold the phone steady?

There are a few tricks that you can use if you are unable to hold the phone steady:

• Try holding the handset against a wall, so that the wall can provide stability.
• Use a firm surface such as a table to anchor your elbows and provide extra stability.
• Use a tripod or phone holder to keep the phone in place.
• Ask somebody to hold the phone for you.
