Google's Nexus One looked the business during its launch demo last week, but now customers who have bought the phone are logging up the complaints.
According to the BBC, many users have filed complaints on the support forums that Google has set up. Ironically, many of the complaints relate to Google's email-only respond policy, with calls for the company to set up phone support.
Other complaints included problems with the phone's support for 3G networks, glitches when syncing contact books, and in some cases, problems even getting the phone to work with Google accounts.
The phone is only available from Google, not from HTC which manufactured the phone, or T-Mobile, Google's operator partner in the US. However, both companies have released conflicting information about the phone, in particular about its 3G support.
A Google spokesman told the BBC that 'this is a new way to purchase and support a mobile phone, and we're committed to sorting out the few kinks that do exist.'
The Nexus One is currently available exclusively from Google for US$529 (£331) unlocked, or US customers can also get it on contract with T-Mobile for US$179 (£112). The phone will come to Vodafone in the UK by early April.
