[Sony Xperia 10 Plus ROMs, Kernels, Recoveries, & O] tickhack:
on another forum (4pda) people with our device get problems with touchscreen. Here is an example translated via google translate:

Perhaps the most "popular" problem is the problem with the tach. This includes: random triggering of a wheelbarrow without touching it - the so-called ghostly triggering, non-triggering with real touches. I note that before the 10k update, this happened in my phone, but very rarely, let's say only 3-4 times for all 9 months of using the phone before the 10k update. But after the update, the described problems with tach occur, attention, almost every session of using the phone, in other words - this problem really delivers. And after the 10k update, two updates have already been released (53.1.A.3.34 and 53.1.A.3.57), which I installed consistently and none of them solved the problem, nor even improved or worsened the situation. Specifically, on my phone, this happens in something like this scenario, for example:

- I hear a notification about a message in Telegram (in fact, the application can be absolutely any, Telegram is just for example);

- unlock the phone;

- I get into Telegram;

- I start typing the answer and notice that there are a lot of missing letters in words;

- put the cursor in the right place, tap on the desired letter - the letter does not appear;

- I change my finger from the index to, say, the middle one and lo and behold, they type a letter;

- then you can continue typing with the middle one, but this is exactly another 5-10 characters and no longer responds to the middle finger either, but again, not all letters, but randomly on the keyboard;

- returning to the index finger can help or not help at all, it comes to the point that both fingers are already "banned" by the phone, then a light but sharp blow with the end of the finger (with its leather part: lol :) in about the middle of the screen can help , but accuracy is not needed here, almost always this solution gives a margin of another 10-20 characters with any finger, but the sensitivity fades again;

- and then a ghost gets down to business, which begins to use it himself, mainly and most often he uses the upper third of the screen vertically and the middle third horizontally (someone in this forum thread described the same areas of the screen), which means by itself the shutter leaves, the panel opens with the function disabled and then randomly - the wifi is extinguished, the bluetooth is turned on, the "on the plane" mode is turned on - all this is randomly selected by the ghost.

It helps for a while, turn off the screen, unlock and continue entering the message, but this is not for long, plus you often need to enter each character twice so that it is "printed". Let's just say, if I tried to dial this message of mine on the forum from the phone, I would have shot myself about 10 times already. : lol: Separately, I note that during use, the phone never fell or hit any surface, it is used gently (except for hitting the screen with a finger: lol :), did not dip into water. And by the way, rain drops falling on the screen do not spoil the work with the touchscreen at all (as it was on my last Xperia XA Ultra, which just went crazy with it), you can continue to work freely if the main described problem did not arise. Also, the problem can arise in any other application and not be associated with typing, for example, when scrolling through the Instagram feed, there simply the touch stops responding to the scrolling movements and a ghost appears again, chaotically opening everything.
