As with everything. It depends on what the kids install and, importantly, how the additional memory card is integrated into the system. I was able to install an SD card on a cheap SAMSUNG smartphone back then. However, the Samsung smartphone did not offer the option of fully integrating the card into the system. It was almost like an additional drive. Apps, pictures, music - everything had to be moved to the card manually. You couldn't select the card as the main memory - it was just annoying. I think the XIAOMI Pad 6 mentioned above should have enough resources for now. And if the memory is cluttered with unnecessary junk, you can learn to "tidy up your room" and practise moderation. Not everything is always and everywhere inexhaustibly available. To answer the question. After the failure of the Samsung device mentioned above, I would always buy a tablet/smartphone that doesn't have the minimum configuration. If it also offers the option of installing an SD card later, then okay, but I wouldn't rely on it being fully integrated into the system before buying it.

Yes, the two products have the same specifications. Regarding the "better" product, it depends on what your requirements are. For personal advice, please contact our customer service directly. :) https://helpcenter.galaxus.ch/hc/de/requests/new
