Smartphone giants Samsung, LG and Chinese firm Huawei are among those set to unveil the newest versions of their devices when Mobile World Congress (MWC) begins on Sunday.
The annual technology trade show, held in Barcelona, has become the regular launching point for Samsung's range of Galaxy smartphones - the current generation S6 was unveiled there last year, and the next generation is expected to debut this year.
Though the event is not attended by Apple, there will still be high levels of industry attention, with LG set to announce their next flagship smartphone, the LG G5, at a press conference on Sunday, a day before the trade show floor opens.
Last year more than 94,000 attended the show, which opens to the public on Monday and runs until Thursday.
Visitors will have the opportunity to see the new phones announced for the first time, and the vast range of tablets, wearable devices and other technologies which are launched during the week.
