Along with launches of new smartphones from major players like Huawei and LG, two former giants - Nokia and Blackberry - will attempt to make a comeback with new devices.
Nokia is reportedly set to reveal several new devices at the four-day Mobile World Congress (MWC) in Barcelona in northeastern Spain, including an updated version of its iconic 3310 phone.
Blackberry will debut a new high-end device rumoured to be called the Mercury. Like Nokia, its new phones will be made under licence by a Chinese manufacturer.
"Don't expect innovation on smartphones' hardware, but instead a focus on emerging technologies" like virtual reality and artificial intelligence (AI), said Forrester analyst Thomas Husson.
Samsung Electronics, which had to discontinue its Galaxy Note 7 smartphone last year after several cases of the devices exploding, will not unveil any new phones at the congress.
The delay in putting out a new phone comes as its parent firm, South Korean conglomerate Samsung Group, is caught up in a corruption scandal that saw its chief arrested last week.
Samsung is the world's biggest seller of smartphones but saw its share of the world's market shrink by two full percentage points to 20.5 percent, according to the Gartner consultancy.
It faces growing competition from Chinese phone makers on one side and on the other from US titan Apple, which released its iPhone 7 in September.
Strong sales of the iPhone 7 helped Apple to post record revenues of US$ 78.4 billion (82.6 billion euros) in the final quarter of 2016 although it also lost market share last year.
Apple, the world's second biggest seller of smartphones, is not present at the show in Barcelona.
With Samsung not unveiling a new phone, the rest of the industry will have a rare opportunity to grab the spotlight in Barcelona.
The congress comes as smartphone sales in developed markets, mainly Western Europe and North America, are poised to peak this year, according to research firm CCS Insight.
"Unless we see a major new disruption similar to the one prompted by the Iphone's arrival in 2007, we expect smartphone sales in Western Europe and North America to slowly decline after 2017," said CCS analyst Jasdeep Badyal.
CCS predicts the global phone market will reach 2.35 billion units in 2019, up from 1.96 billion in 2014.
