OTA is short for Over The Air, and as the name suggest, the process involves updating your phone with enhanced firmware or operating system or both remotely.
How OTA updates for latest Android operating system are finalized?
When Google announces new Android operating system, it distributes Platform Development Kit for all Android partners to analyze the framework. A similar procedure is also followed by Microsoft before Windows Phone update.
Why are OTA updates to my phone delayed even after roll out starts?
Most OEMs roll out update in batches. Only about 1 to 2 percent of devices get the update in the first batch. The update adoption rate, error reports and other data is monitored and analyzed before the second bigger batch is dispatched. The process can continue for several weeks based in your region, but rest assured you will get your update sooner or later.
Conclusion
Patience is the key here. It’s hard to determine when you will get OTA updates on your smartphone, but considering the process involved, you can expect it to be always delayed compared to consumer expectations. If your device is out of warranty period, you can always flash custom ROMs with updated OS instead of waiting for official OTA updates.
