The display can certainly still be rated as quite positive here. Unfortunately, however, the manufacturer relies on old or weak components at many points. The TrekStor tablet is a good idea in itself: a large display with integrated stand and stereo speakers, which can serve as a multimedia centre for the home. However, the protective film quickly becomes dull and offers the fingers a lot of sliding resistance. In the test, the touch screen reacts precisely and sufficiently quickly to touches. This doesn't happen very quickly in combination with our reference router Linksys EA8500, because the TrekStor tablet remains below its capabilities, but does not show any interruptions in data transmission. The WLAN module supports the IEEE 802.11 standards a/b/g/n (Wi-Fi 4) and can transmit in both 2.4 and 5.0 GHz networks. After all, bloatware is not found on the tablet.
The operating system used is Android 9.0 Pie, which is equipped with the security updates of at the time of the test. We are a little irritated that a proprietary power connection and not USB is used for the power supply. The latter, however, does not support exFAT. In addition to two full-fledged USB-A ports, the connectivity offers an additional microHDMI port for wired image output, an audio jack and a slot for memory expansion using a microSD card. Only the already applied display protection foil already shows some air bubbles on our test device. The integrated kickstand is also made of metal alloy, is sufficiently stable and infinitely adjustable. The case of the Theatre S11 consists of a neatly processed mixture of aluminium and plastic.
