Samsung Galaxy Tab A9+ (SM-X210): problems, parts and running costs

Checked: 2026-10-19

Summary

Owners most often report lag on this 4GB/64GB version, ghost touches and slow charging, and no power adapter is included in the box. Running costs are minimal: about $3 a year in electricity and no routine consumables or subscriptions. It is a good buy at $150 or less new from a credible seller; at $190 or more it is a poor buy.

Common problems and fixes

Lag and slow app navigation — the most common complaint on the 4GB/64GB version; owners in January 2025 and January 2026 threads describe severe lag and delayed app navigation, with one participant contrasting a smoother 8GB version. A lighter workload, fewer background apps and current software updates may help, but physical RAM cannot be increased. Covered by the 12-month limited hardware warranty if it is a defect. [1][2][10]
Ghost touches and unresponsive screen sections — reported in threads from 2024 through 2026, including after One UI 7 and One UI 8 updates. Clearing the system cache helped one owner temporarily; a factory reset did not fix another. Removing cases and screen protectors is diagnostic, not a guaranteed cure. [3][4][5]
Tablet unresponsive after an update — a March 2026 Samsung US community report described a Tab A9+ that stopped responding after updating to One UI 8; Samsung advised charge, restart, Safe Mode or service. A single case, not a published failure rate. [6]
Slow charging, no adapter in the box — a full charge from empty took 2h 58m with a third-party 20W adapter, and only a USB-C cable is included. Budget for a charger. [7][8]
Storage fills quickly — about 41GB free after the OS and preloaded apps on the 64GB model; a microSD card expands files and media but not internal app storage. [7]

Parts and consumables

Samsung 15W USB-C charger (EP-T1510XBEGUS) — $19.00 at Samsung US, listed October 2026 (regular $19.99); not included in the box, so most owners buy one once. Replace only on failure or damage. [8]
Samsung Book Cover (EF-BX210TBEGUJ) — $49.99 at Samsung US, listed October 2026 but shown out of stock; optional, with no replacement schedule. One owner reported the magnetic closure weakening after roughly one year. [9]
SanDisk Ultra 256GB microSDXC (SDKSQUNR256GB) — $55.99 at Best Buy, listed October 2026; optional file storage, not extra system RAM. The tablet supports microSD up to 1TB. [11][7]

Yearly running cost

About $3 a year in electricity for one full charge per day, an assumption-based estimate using the 7,040mAh cell, roughly 75-80% wall-to-cell efficiency and $0.20/kWh. No routine consumables, no subscriptions and no data plan on this Wi-Fi-only model. A case, microSD card and charger are one-time purchases. Repairs are excluded: one 2024 owner cited a $110 repair quote on a $180 tablet. [3][7]

When it is a good buy

Best Buy listed the exact 4GB/64GB Graphite SKU at $197.99 on clearance in October 2026; Target listed it at $219.99; Walmart advertised the same 4/64 Wi-Fi model in Navy at $149.00. [12][13][14]
Buy at $150 or less new from a credible seller. At $151-$179 it is conditional: only if the Samsung ecosystem and headphone jack matter and you accept the 4GB RAM. At $190 or more it is a poor buy. [7]
Alternatives: the Galaxy Tab A11+ 128GB at $219 from Walmart (October 2026) is the better choice when newer software and more storage matter; the Lenovo Idea Tab 11-inch 128GB at $219.95 at Best Buy (October 2026) has a sharper 2560x1600 display; the S Pen-equipped Galaxy Tab S10 Lite at about $399.99 at Best Buy (October 2026) is the better choice if you need handwriting.
