Samsung has already officially announced that the Galaxy S9 and S9 + will be presented during the Mobile World Congress 2018 held next month, of course, both devices will have all the spotlight's attention, so they won't leave much room for other devices to shine.
Thinking about this, LG and Huawei may not present their flagship devices during MWC 2018 and do it at exclusive events afterward.
Huawei P11 and LG G7 presented in March or April
It is speculated that the LG G7 will be released in March or Aprill, while only an advanced version of the LG V2018 will be presented at MWC 30.
On the Huawei side, things would go the same way, The Huawei P11 would be presented at an exclusive event sometime in April, it is likely that the company only presents tablets and a 2-in-1 laptop. It is also rumored that this change is not due to the presentation of the Galaxy S9 and S9 +, but to last minute modifications, perhaps changing some of its already leaked characteristics.
If we remember we will remember that last year, during MWC 2017, Samsung presented the Galaxy Tab S3, while LG announced the LG G6 and Huawei did the same with the P10 series.
Of course, with the introduction of the S9 and S9 + during this year's MWC, everything changes. Experts assure that many companies will seek to avoid splicing the presentation of their most important devices with the launch of Samsung, so it is almost a fact that we will not have another very important announcement during the event, although there are several new mid-range / low-end devices .
Lastly, the Galaxy S9 and S9 + are expected to arrive worldwide in March, first in its pre-sale phase on March 1 to be shipped on the 16th of that same month.
