Not for years: it’s 15 years old and Samsung no longer gives it security patches.
Before you pay: the seller signs out of their Google and Samsung accounts in front of you.
What to check before you pay
Five minutes that save you a headache:
Google and Samsung accounts signed out, in front of you. Otherwise the tablet stays locked when you reset it. Don’t buy a locked tablet, not even at a discount.
Battery: charge it for a while. If it heats up or drains fast, plan on replacing the battery.
Wi-Fi, the cameras, the speakers and charging.
Where to buy it
There’s no Samsung Galaxy Tab 10.1 (2011) for sale on Damjitech right now.
