Touchscreen digitizer failure makes typing and scrolling unusable until restart
From a Galaxus (EU retailer) Q&A thread on the Redmi Pad SE 11" 128GB. An owner describes the screen registering phantom repeated keystrokes and rapid taps while scrolling; only a restart temporarily fixes it and the problem recurs regularly. The owner suspects the digitizer. This is a hardware fault that makes the tablet hard to use and typically needs a screen/digitizer replacement.
What to check. Test the touchscreen thoroughly during the return window; if ghost input appears, claim warranty rather than paying for a digitizer swap.
From the same Turkish Şikayetvar page. An owner reports that after a system update the battery began draining excessively, dropping from 100% to 80% on its own within a few hours, and after a restart the charge fell from 30% to 1%. This is a power-domain complaint tied to a software update rather than a hardware defect.
What to check. If you see rapid idle drain after an update, check for a runaway background process before assuming the battery is faulty.
Lag during gaming from thermal throttling and low memory
From Xiaomi's own support FAQ for the Redmi Pad SE 8.7. Xiaomi itself acknowledges the tablet lags in heavy gaming because of thermal throttling and lack of memory. This is a performance-domain limitation a buyer should expect on this entry-tier hardware.
What to check. If you plan to game or run many apps, expect lag; close background apps and avoid long heavy sessions on this model.
Redmi Pad SE lag under load: thermal throttling and low memory cause lag in games and multitasking
Xiaomi's own FAQ for the Redmi Pad SE 8.7 acknowledges lag during gaming and multitasking, attributing it to thermal throttling under heavy load and to limited memory (the entry model ships with 4 GB RAM). This is a manufacturer-confirmed performance limitation rather than a defect, and matters most for buyers who expect smooth gaming or heavy multitasking from an entry-tier tablet.
What to check. Expect lag in resource-intensive games and heavy multitasking on the Redmi Pad SE; close background apps and avoid long gaming sessions if you want smoother performance, and consider the higher-RAM variant if performance matters.
Redmi Pad SE touchscreen/digitiser ghost input: wrong characters typed, recurring until restart
Owner question on the Galaxus (EU retailer) Q&A for the 11-inch Redmi Pad SE describing a recurring touchscreen fault: typing produces repeated wrong characters and scrolling registers as rapid taps, and the only fix is restarting the tablet, with the problem returning regularly. The owner suspects the digitiser. Other owners in the thread report no such issue, so this appears to be a unit-level hardware defect rather than universal.
What to check. If you see ghost input/repeated characters on a Redmi Pad SE, restart first, then check whether it recurs; if it does, file a warranty claim early since the owner suggests a digitiser fault, and note that some units are unaffected.
From a kakaku.com (Japanese review site) user review of the Redmi Pad SE 4GB+128GB. The reviewer notes the Wi-Fi connection occasionally drops. This is a connectivity-domain complaint, though it is a single owner report and the cause is not confirmed.
What to check. If Wi-Fi drops recur, test against multiple routers before assuming a hardware fault; a weak or flaky radio may need service.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
