@Cassidy - If Root is available for any device & if there's any Custom Rom Development for the device - Then sure you can likely Flash a more current Android version - I've never owned a Samsung Tablet - So I don't know how much Development there is? Just like I have Android 10 running on my Note 3 & Pie running on my Note 4 - But these are fairly popular devices and there's a lot of Development for them - Same with the S7 incidentally - I was running Pie on it before I sold it - XDA is a good place to look for Custom Roms for your Tab 🙂🐧
CHMultimedia SM-T230NU if it could be flash, i need a version that could integrate Sd card like if it was internal stockage because this tablet have only 8 gb internal memory but was perfect for my appointment...
Tab A 4 7.0... Ah I see why you didn't get any update. There is however an official firmware with Oreo. It's for the T230NZ, a 2018 refresh which seems to have the same specs. You could give it a try?
I don't have that app indeed. Also the link here leads to incompatible ROMs. The Tab 4 7.0 uses a Maxwell SoC, the two other tablets uses a Snapdragon 400.
