Whether you’ve flashed any other custom firmware on your Vivo Y70s device and now you want to go back to the stock firmware ecosystem again or the third-party firmware flashing process didn’t go well and you want to unbrick or restore your Vivo Y70s device, this guide is only for you. It’s worth mentioning that the stock firmware not only unbricks/restores your device but also offers all the official benefits like the optimized software, latest software updates, latest security patch updates, battery optimization, warranty support (if any), smoother & stable performance for daily/multitasking usage. Talking about the Vivo Y70s device specifications, it has Samsung’s Exynos 880 SoC, Android 10 (Funtouch OS 10), a 6.53″ IPS LCD display, 6/8GB of RAM, 128GB onboard memory, 48-megapixels triple rear cameras, a 4500mAh battery (18W fast charging), a side-mounted fingerprint sensor, 5G connectivity, and more. Now, let’s check out all the useful features of having the stock firmware on your device.
Stock Firmware Features
Stock ROM always comes preloaded with the device according to the model-specific for a specific brand. Each and every device model as well as each & every OEM does come with its own specific stock firmware. Stock ROM basically designed for the individual device model that runs smoothly and offers more stability, battery optimization, official software updates, fewer lags or stutters, etc.
While custom firmware (Custom ROM) is an aftermarket software that can be installed on your device (if compatible). But due to the unofficial firmware, it won’t get any brand-specific official software updates, may not get official support (under warranty), the stability & performance may get decreased, etc. Additionally, you’ll start noticing multiple bugs, errors, crashes, glitches, stutters, frame drops, unusual battery draining, device overheating, app crashes, app update failed, stock Google apps error, and lot more. Whereas, sometimes users can’t properly flash the third-party firmware due to multiple processes, and more. In that case, it’s quite common to easily get bricked or stuck in the bootloop issue due to some flashing mistakes or file compatibility issues. So, it’s a good idea to either go back to the stock official firmware after checking out the third-party unofficial firmware or always stay on the stock ROM to get maximum performance, stability, and most importantly, official software updates.
