What is OTA and the pros & cons of OTA upgrade?
OTA (Over-the-air programming) refers to a method of distributing new software, configuration settings, or updating encryption keys to devices like cell phones, TV boxes, etc.
What is OTA?
One necessary feature of OTA is that a central location will send an update to any users at once, who are unable to refuse, damage, or alter that update, which the update applies right away to everyone on the channel. A user might refuse OTA update but the channel manager could additionally kick them off the channel.
Because mobile phones accumulate voluminous new apps and become more advanced, OTA configuration has become vital as new update technique and services return on stream. OTA permits the distribution of the latest software updates to smart devices with the necessary settings with which to access services like WAP or MMS.
If your device doesn't have OTA, you will have to:
(a). Seek help from shop.
(b). Connect the devices and computer with a cable, thereby alter the device's configuration, and add software to devices, etc.
In modern mobile devices like smartphones, OTA updates may simply refer to obtaining distributed software updates via Wi-Fi, mobile broadband and built-in function in the operating system, where "over-the-air" refers to wireless Internet application, without the need for users to connect the device to the computer via USB connection to perform updates.
OTA upgrade can be completed directly online in the phone by using the mobile network or Wi-Fi. There is no need to back up data in upgrade, and you just need to reboot your phone after the upgrade is completed.
OTA upgrade has no obvious shortcomings, but in the upgrade process, it will download some upgrade package, which will occupy some phone's memory storage space. And if your phone system gets stuck, OTA upgrade also can not solve the problem. But if you flash firmware upgrade, the system will return to the original state, which may have some help for system fluency. However, flash upgrade takes more efforts, and will empty the data in the phone.
